Chess Rules on the Chess.com Platform

While following one of the games from the Tuesday Night Marathon on our broadcast, we commented on a game where given the pieces on the board, there was a strategy possible for one of the players to attempt to sacrifice material to get down to the classic King, Bishop, and Rook pawn vs. King, with the bishop being the opposite color of the queening square, leading to a theoretical draw. A moment later, someone watching our stream asked in the chat what the rules were on Chess.com regarding draws on the platform, whether it uses USCF or FIDE rules. This made me think that it would be beneficial to explain this to our readers, especially given the volume of games many of our players play on Chess.com and that it is the preferred platform of Mechanics' Institute.

I reached out to Chess.com staff. Here is what was told to me regarding the rules and platform.

We don't follow FIDE or US Chess directly for various reasons, including the fact that these rules cannot always map directly onto an online system, that there is no arbiter in the system, and that online chess primarily consists of blitz and bullet and not classical. Our implementation is designed to provide the best possible experience for our members, most of whom are casual players and have no exposure to USChess or FIDE rules.
 
This makes sense. The platform was designed to play chess and adhere to the basic rules of chess, not to be responsible for rated chess and being malleable to the nuances of USCF vs. FIDE rules. An example of the difference between USCF and FIDE rules and how it can come into conflict with the platform is a game where a player has a king and two knights vs. a lone king. In this example, under USCF rules, the game is declared drawn since it cannot force mate. Under FIDE rules, the game is not declared drawn, as it is possible to mate, though the lone king would have to be a willing participant. 
 
So in this respect, it seems that Chess.com follows USCF rules, because as it states here: https://support.chess.com/article/128-what-does-insufficient-mating-material-mean, a king and two knights is considered insuffient mating material. 
 
Chess.com also auto recognizes three-fold repetition and 50-move draws according to USCF rules. 
 
So the simple answer is it does not specifically conform to either USCF or FIDE rules, but was designed rather to conform to what is commonly recognized as standard rules of chess. It pretty much adheres to all the rules except in certain instances, where it may differ between a USCF or FIDE rule. An unforseen challenge may arise for example if a tournament is run on a platform where it does not account for a nuanced rule, for example, if an event goes by FIDE rules, but uses Chess.com as a platform. A rule like the king and two knights vs lone king would come at odds with the server capability, and so the tournament director and organizer would have to decide what to do in that instance.
 
Best practice for organizers and tournament directors of online rated chess is to announce in advance if there should ever be the possibility that a specific USCF or FIDE rule cannot be observed given the parameters of the platform, and what the arbiter will do if the situation arises. We are all learning best practices as we go, and new challenges arise as we push the envelope of utilizing online chess to play competitively. As long as we all keep the dialogue open and keep players informed, we are keeping the integrity of the game intact.
 

Ray Conway Memorial Tuesday Night Marathon Report

The Tuesday Night Marathon concluded rounds 5 & 6 on Tuesday night, with the top players rising to the top. IM Elliott Winslow played a very inspiring and aggressive draw against GM Gadir Guseinov, a game in which it appeared he may even have had some winning chances. He now sits as the sole leader of the Ray Conway Memorial Tuesday Night Marathon with 5.5/6 with 2 rounds to go. FM Kyron Griffith won both of his games in very quick fashion, pulling him right behind Elliott with 5/6. Also on the heels of Elliott is NM Michael Walder, who also has 5/6. Trailing at 4.5/6 are GM Guseinov, IM Prasanna Rao, Felix German and Javier Silva. The final two rounds next week will surely produce some action, as the top players battle to climb the ladder. 

Here are some games from Tuesday, annotated by GM Nick de Firmian.

1.e4 c5 2.Nc3 d6 3.Bb5+ This as-yet unnamed line has been appearing in the Bay Area among some of the top players -- in fact, this is the third time Winslow has been up against it. Maybe he's starting to catch on. [One can find quite a few games where Guseinov has played 3.d4 cxd4 4.Qxd4 Nc6 5.Bb5 for example 1-0 (23) Gadir Guseinov (2586)-Davit Shengelia (2523) Baku AZE 2007(but after a string of losses he switched to 5.Qd2 (analyzed in NIC #128 "The Birth of a New System", by Ioannis Simeonidis) and won: 5...e6 6.b3 Nf6 7.Bb2 d5 (7...a6 8.0-0-0 b5 9.f3 h5!? 10.Nh3 Be7 11.Ng5 h4 12.f4 Bb7 13.Kb1 Rc8 14.Be2 Qc7 15.Rhe1 Nh7 16.Nxh7 Rxh7 17.g4 1-0 (31) Carlsen,M (2843)-Wojtaszek,R (2744) Shamkir 4.23.2018 was the game that started quite a run on this line.

Bxg5 17.hxg5 e5 18.dxe6 Rxe6 19.Rxe6 Qxe6 and Black held on: 1/2-1/2 (54) Guseinov,G (2665)-Baches Garcia,G (2329) chess.com INT 2020; 11...Nh5!? 1/2-1/2 (33) Shimanov,A (2593)-Grischuk,A (2777) chess.com INT 2020] 12.h3

MIOnlineOct23_1276
Black doesn't have any conspicuous reason to be unhappy with the result of the opening. 18...Rac8?! [and in fact Stockfish thought it was some advantage after 18...b5] 19.Rad1 Rfd8 20.c3 a6?! 21.Kh1 Ng6 22.Rd2 Be5 23.Bf2
MIOnlineOct23_1277
23...Bf4! Black decides to take out the white knight before it can get "tricky." His remaining minor piece will have no trouble finding squares. 24.Rfd1 b5 25.Re2 Bxe3 26.Bxe3 Qc4?! 27.Red2 Qxb3 28.axb3 Rc6 29.Bd4 e5 else 30.Bf6 would be disruptive; the hole on d5 isn't a problem, seeing as how White has no knight to plant there. 30.Be3 Kf8 31.Kg1 Ke7 32.Kf2 Ke6 33.b4 [33.g4!?] 33...f5 keeping the balance 34.exf5+ Kxf5 35.Ra1 d5 It's hard for either side to make progress, except for one factor: the experience imbalance. Guseinov has been playing these lines since he was European Under-10 Champion (he was born in 1986), and he's used a grand total of six and a half minutes on his clock, while Winslow has burned almost two thirds of his time. And it gets worse, as he tries to avoid ghosts. 36.Bc5 Nf4 37.Rad1 Ke6 38.Be3 Ng6 39.Kg3 Rc4 40.Bb6 Rd7 41.Ra1 Rc6 42.Bc5 h5 43.Rdd1 Nf4 Times: White: 26:38, Black: 10:10 44.Rd2 Rg7!
MIOnlineOct23_1278
Black tries to give his grandmaster opponent something to be concerned about. 45.b3? [45.Kf2 g4 46.hxg4 hxg4 47.Rh1=] 45...Kf5 46.Kh2 g4 [46...h4!? when the weakness of c3 is a factor.] 47.g3 Nxh3 48.Rxd5 [48.Rf1!?

MIOnlineOct23_1279
50.Rxe5+! Tactics in the Endgame indeed! 50...Kxe5 51.Bd4+ Ke4 52.Bxg7 White has won a pawn for now, but Black's king rules. 52...Nf3+ [52...Rd6!?] 53.Kg2 Rg6 54.Bf8 Kd3
MIOnlineOct23_1280

55.c4! White heads for safety, eventually trading off the queenside pawns and continually harrying Black. Now follow a lot of moves, leaving Black with very little time, but in the end he finds a repetition that can't be avoided. 55...bxc4 56.bxc4 Kxc4 57.Kf2 Rf6 58.Be7 Re6 59.Bc5 Kd3 [Last chance for a plus: 59...Nd2!] 60.Ra3+ Kd2 61.Be3+ Kc2 62.Ra5 Kc3 63.b5 axb5 64.Rxb5 Truthfully the players could make peace here. 64...Ra6 65.Bf4 Re6 66.Rd5 Kc4 67.Rd8 Times: 22:04 3:02 67...Nd4 68.Be3 Rf6+ 69.Kg2 Nf5 70.Bf2 Re6 71.Rg8 Re4 72.Rg5 Nd4 73.Ra5 Nf3 74.Ra2 Kd3 75.Ra3+ Kc4 76.Ba7 Re2+ 77.Bf2 Re4 78.Ra8 Kd3 79.Rb8 Kc4 80.Rd8 Kc3 81.Rd7 Kc4 82.Ba7 Re2+ 83.Bf2 Re4 84.Kf1 Nh2+ 85.Kg1 Nf3+ 86.Kg2 Kc3 87.Rg7 Kd3 88.Rc7 Rc4 89.Rd7+ Ke2 90.Re7+ Kd3 91.Re3+ Kd2 92.Ra3 Re4 93.Ra6 Rc4 94.Re6 Kd3 95.Re7 Re4 96.Rf7 Ke2 97.Ba7 Kd3 98.Rd7+ Ke2 99.Rg7 Ke1 100.Bf2+ Ke2 101.Rf7 Kd3 102.Rf6 Ke2 103.Bb6 Ne1+ 104.Kh1 Nf3 105.Rc6 Re5 106.Kg2 Ne1+ 107.Kg1 Nf3+ 108.Kg2 Ne1+ 109.Kg1 Nf3+ 110.Kg2 It's been "0.00" for the last 50 moves: Game drawn by repetition 1/2-1/2

1.c4 g6 2.Nc3 Bg7 3.Nf3 d6 4.g3 Nf6 5.Bg2 0-0 6.0-0 e5 7.d4 Nbd7 It's now the King's Indian Defense, Classical Fianchetto. 8.h3 [This is usually only played after 8.e4 c6] 8...c6 9.Be3 White goes another way. Does Chelsea know "theory"? Perhaps she was thinking about the Panno Variation, where instead of ... Nbd7 and ...c6 Black has played ...Nc6 and ...a6. In that position the moves h3 and Be3 used to be quite a main line. 9...Qe7 [This old game is in the database 9...exd4 10.Nxd4 Qe7 11.Qd2 Re8 12.Bh6 Bxh6 13.Qxh6 Nb6 14.b3 d5 15.cxd5 Qb4 16.Qh4 Qxc3 17.Rac1 Qa5 18.Qxf6 Nxd5 19.Qh4 Nc3 20.Rc2 c5 21.Nf3 Bf5 22.Ng5 h5 23.Qc4 1-0 Lombardy,W (2520)-Winslow,E (2250) US Open (9) Fairfax 1976] 10.Qd2 e4 Producing quite a different battleground:

MIOnlineOct23_1255
11.Ne1N [The previous, probably not too important game was 11.Nh2 1-0 (36) Schwaninger,U (1892)-Vokroj,G (1792) Frohnleiten 2000] 11...d5 12.cxd5 cxd5 13.Bg5 [The standard attack on Black's center here would be 13.f3 but coupled with h2-h3 it starts to look pretty loose on the kingside.] 13...Nb6 14.b3 Letting herself be led around. (This move wasn't necessary.) 14...Be6 15.Nc2 Rfc8 to keep a7 guarded vs. Nb5 [15...h6!? 16.Bxh6? Bxh6 17.Qxh6 Rac8 18.Qe3 Qc7 19.Nb5! Qd7! (19...Qxc2 will be a perpetual on the queen) 20.Nba3 Bxh3 21.Qh6! Bxg2 22.Kxg2 Ng4 23.Qg5 Kg7 24.Rh1 Rh8 25.Ne3 White is looking to hold the line.] 16.Rac1
MIOnlineOct23_1256
16...h6! The first appearance of the Overworked Queen theme in this game. 17.Bf4?! [17.Be3; 17.Bxh6? Bxh6 18.Qxh6 Rxc3] 17...g5?! [17...Nh5! 18.Be3 (18.Be5? f6 19.Bf4 g5 20.Be3 f5 gives Black a free move) 18...g5 is dangerous for White. (or 18...f5 first) ] 18.Be5! Nfd7?! [18...Nh5! 19.Bxg7 Kxg7 20.Ne3 f5] 19.Bxg7 Kxg7 20.Ne3 f5
MIOnlineOct23_1257
21.Kh2? White needs to stop the bulldozer: [21.f4!+/- has to be played, which is fine -- it exposes the weakness of f5 (and Black wishing his rook were still on f8).] 21...f4-/+ 22.Nc2?!
MIOnlineOct23_1258
[22.Ned1!?] 22...a6?! [22...Nf6! makes better use of the O.Q. theme, and gets that knight back on track to h5 where it's doing something (pressuring g3).] 23.gxf4 gxf4
MIOnlineOct23_1259
24.Qxf4? Sacrificing a piece for some dangerous threats, which indeed Black mishandles. [But 24.Rg1! would have been more sophisticated, even if the computer finally finds some advantage for Black: 24...Kh8!! (24...Kh7? 25.Nxe4!+-) 25.Qxf4 Rxc3 26.Qxh6+ Qh7 27.Qxe6 Rc6! 28.Qg4 Rg8 29.Qf4 Rf6 30.Qe3 Qh4 31.Rcf1 Rfg6 and despite the two-pawn deficit, the computer makes Black doing pretty well.] 24...Rxc3 25.Rg1 Qf6 [25...Kh7! is safe when White doesn't have the knight to play Nxe4 any more! 26.Bxe4+ fizzles: 26...dxe4 27.Qxe4+ Kh8 28.Rg6 Rxh3+ 29.Kg1 Bd5! is a rude surprise.] 26.Qd2 [26.Bxe4+ Kf7] 26...Rac8 27.Bxe4+ Kh8 28.Bf3
MIOnlineOct23_1260
[28.Bd3 Bf5! is the best according to Stockfish 12.] 28...Qh4? Sure enough, defense is hard. The following moves all would have been winning: [28...R8c6; 28...Kh7; 28...Nf8; 28...Bf7] 29.Rg3? [29.Rg6! when Black is lucky to have two paths to a draw: 29...Kh7 (29...Qxh3+ 30.Kg1 Kh7 31.Bg2 Qh4 (31...Kxg6 32.Bxh3 Bxh3=) 32.Rxe6 Qg5 33.Re3 R3c6 is a pin that's hard to break: even game.) 30.Rxe6 Qxf2+ 31.Bg2 (31.Kh1 Qh4 32.Kh2 (32.Bg2??

[30.Ne1? Ne4!-+; 30.Ne3! Rxc1 (30...Ne4 31.Bxe4 and no ...Rxg3!) 31.Ng2! Black's queen is "trapped, although the knight-check and QxR+ both draw.] 30...Qxh3+ 31.Kg1 Ng8 [31...Kh7!] 32.Bg4!? The computer suggests all sorts of moves that are "only' around -4.7 (vs. -8 for the move played), but Black was confused and took a lot of time here. 32...Bxg4 Hard to give this an exclamation point! [Times: 4:30 4:07] [32...Rg3+ was the alternate, forcing a draw. 33.fxg3 Qxg3+ 34.Kh1 (34.Kf1?? Rf8+) 34...Qh4+ 35.Kg1 (35.Kg2 Bxg4 starts to get uncomfortable, with ...Bh3 being check) ; 32...Qxg4+ 33.Rxg4 Bxg4 34.Qf4! isn't good for anything (except maybe a draw) either.] 33.Rxb6
MIOnlineOct23_1261
[33.Qf4!? was the scary move, but when you're two pieces up there are a lot of roads to a successful defense. Either rook along the c-file (c6 or c7) was enough, but best was 33...Qh5! e.g. 34.Rxg4 Nd7] 33...Rg3+? Black just didn't see the knockout: (and now 2:23 left) [33...Bf3! 34.exf3 Nf6!] 34.fxg3 Qxg3+ 35.Kh1 Bf5 [3:13 2:23] and Chelsea didn't see the defense - and resigned! [

1.e4 e5 2.Nf3 Nc6 3.Bb5 d6 The time-worn Steinitz Defense. 4.0-0 Nothing wrong, [but 4.d4 tries to upset Black right away and encourage ...exd4, when White has a space advantage (but Black is solid for now).] 4...Nf6 5.Re1 Be7 6.c3 [Or 6.d4 still, reserving c3 for the knight.] 6...0-0 7.h3

7...g6!? Played after two seconds (!). In fact, with a time control of 35 minutes and an increment of two seconds, David's clock now read 34:57! And that's about how it went the whole game. [Most common is 7...Bd7; or 7...a6; 7...Nh5? 8.Nxe5 was the course of one game whose players shall remain unnamed.] 8.d3?! Too passive. Black's plan is ...Nh5 and maybe ...f5? Then White should "meet a wing attack with a counterattack in the center" -- [8.d4! exd4 9.cxd4 Bd7 10.Nc3 Re8 11.b3 a6 12.Bd3 Nb4 13.Bb1 c5 14.Bb2 Nh5 15.a3 Nc6 16.Nd5 Bf6 17.g4 Ng7 18.e5 and White crashed through: 1-0 (26) Gimenez Aguirre,I (2234)-Prado,I (2063) La Cumbre 2019] 8...Nh5 9.Be3 [9.d4!+/- Better late than never!] 9...Bd7 10.Nbd2 [10.d4!] 10...Bf6 Black shuffling of his pieces, allowed by White's cautious buildup. 11.Nf1 Qe7 12.a4 a6 13.Bc4 Na5 14.Ba2 c5 Standard queenside expansion by Black Times: White: 30:12, Black: 34:15.

[20.Ba2! followed by d4 and/or Nc4 keeps Black's game dire.] 20...Nxd5 21.cxd5 Bb5 22.Nc4 Nf4 Black still hasn't gotten around to ...f5 23.Red1?! giving Black's knight the option of ...

28...exd4?! [28...cxd4!-/+ and White's chance of opening up the b-file goes away.] 29.Rc1?! [29.Re1! White has a new lever -- e5! -- and should play for it.] 29...h5 30.Rdc2 Bg7 31.Nh4 Bh6 32.Re1 White has been burning up his clock (finally!) and is down to 6:36 left (Black: 32:41, having spent less time on the last dozen moves than White has on almost any one of them!). 32...Qf6?! [Black could cripple White on the dark squares now: 32...Bg5! 33.Nf3 h4!] 33.Kg2! Re7?! [33...Bg5 34.Nf3 h4 35.e5! dxe5 36.Rxe5 Bh6 37.Rxc5 is a lot of trades, with White on top at the end. 37...Rxc5 38.Qxc5 hxg3 39.fxg3 Bxd3 40.Qxd4] 34.Nc4 Bxc4 35.Rxc4
MIOnlineOct23_1266
35...Re5? 36.b4?! A dangerous but inconclusive exchange sacrifice by White. [36.Nf3 pushes Black back without risk. 36...h4 37.Nxh4 Rh5 38.Nf3 Rxh3 doesn't do it.] 36...cxb4? [36...Bd2! 37.Rb1 Bxb4 38.Rbxb4 cxb4 39.Qxb4+/=] 37.Qxb4 Qe7?!
MIOnlineOct23_1267
This would be a huge win for White, except that he's down to under four minutes (Black has yet to break a sweat -- or 31 minutes!). 38.f4 Going for the whole enchilada, but with some risk to the king. [38.Nf3!] 38...g5!? 39.fxe5 How could you not, especially with 3:11 remaining (and he used almost a minute on it!). [39.Nf5! Rxf5 40.exf5 Qd7 41.fxg5 Bxg5 when White dares Black to take on f5 (and the rooks have the f-file then as well).] 39...gxh4 40.Qxd6?! Qg5

41.e6?? It looked so good in the moment, but it loses -- and he had much much better moves! [41.Kh1! and Rg1 suddenly it's White taking over.] 41...Qd2+ 42.Kf1 Be3! A final instant move -- and it's over. 43.exf7+ Rxf7+ 44.Qf4 Rxf4+ 45.gxf4 Qf2# A tough game to lose by Nicholas -- and as for David's final clock time of 30:51, what fire was there in the kitchen that he played so fast! It could have cost him. 0-1

[de Firmian,Nick]

1.e4 e5 2.Nf3 Nf6 3.d3 This is hardly bad, but no way to play for an advantage. [3.Nxe5 is the classic approach; 3.d4 is the more modern move] 3...Nc6 4.Be2 Bc5 5.0-0 d6 6.h3 h6 7.Re1 Be6 8.Bf1?!

MIOnlineOct23_1269
8...g5! Black takes advantage of not having castled to throw his pawns at White's kingside. Correctly, according to the computer! 9.Be3?! [Incredibly Stockfish finds the idea to play a delayed Evans Gambit, 9.b4 Bxb4 10.c3 Ba5 11.d4 as the best way to minimize the disadvantage (although it is still pretty good for Black).] 9...g4 10.hxg4 Bxe3 11.Rxe3 Nxg4 12.Re1 Nd4 [12...Qf6!] 13.Nbd2 Qf6 14.c3 Nxf3+ 15.Qxf3 White: 31:13, Black: 32:13 15...Qh4 [15...Qg5! gains time attacking the knight, and there follows ...h5 and/or ... 0-0-0, with a winning attack.] 16.Qg3!
MIOnlineOct23_1270
Another case of speed-demoning: the clock times are White: 31:13, Black: 32:04. 16...Qxg3 Keeping queens on might have been right strategically (attack!), but giving White a dreadful pawn structure is right up there in value. 17.fxg3 0-0-0 18.d4 Rhg8 19.Be2 Ne3?! looking for trouble... there's nothing there (for Black...) 20.Bd3
MIOnlineOct23_1271
20...Rxg3?? ...and finding it! [Black should just say no: 20...Ng4 still with a sizable advantage (but the lost time will cost him).] 21.Kf2 Rdg8 22.Rxe3 White is winning. 22...Rxg2+ 23.Ke1 h5 24.Kd1? His biggest think of the game so far, and it's a lemon. [24.Bf1! gets on to the business of neutralizing Black's rooks, with a likely win.] 24...Rf2 [24...Rh2! leaves White with no advantage!] 25.Ke1 At least White admits the error of his ways. 25...Rh2 26.Rf3 and has a clear advantage again. But between moving his king back and forth, and then this (excellent) move, it cost him a third of his time. 26...Rgg2?! and eight minutes for this helpful (for White) move. 27.Nf1 Rh1 28.Rf2 Rgg1 29.d5 [29.Rd1] 29...Bh3?! [29...Bg4!?] 30.Rxf7 [30.Rd1] 30...h4! 31.Kd2 [31.Rd1! Gets the rook in the game.] 31...Bg2 White: 13:27, Black: 11:11 32.Ke3 The best move, but he used the majority of his time. Ultimately that costs him the game. 32...h3 33.Kf2 Bxf1 34.Bxf1 h2 A scary position! Suddenly the black h-pawn has become a force. 35.Rh7 Kd8 36.Rd1
MIOnlineOct23_1272
White still has to solve the problem of dealing with this pin without something awful happening (Black queening!) or slipping into a bad ending. But Black also has a problem: Is this Zugzwang!? [Annoying that 36.Rxh2?? Rxf1+ 37.Rxf1 Rxh2+ 38.Ke3 Rxb2 fails dreadfully.] 36...Rg4 All the "best" moves for Black, according to Stockfish, are pawn moves now. So this lets White free himself! White: 2:09, Black: 6:47. 37.Be2! Rgg1 A trade of e-pawn for h-pawn means that White is ready to get his bishop into the game and after Black's pawns. 38.Rf1?! Only 25 seconds left! (plus the two-second increment) [38.Rd3! and Rf3! is problematic. 38...Rg8 39.Rdh3 Rb1 40.Rxh2 Rxb2 41.Rf7 is going to get ugly on the 7th.] 38...Ke8 39.Ke1! Kd8 40.a4 a6 41.b4 Ke8 42.a5 Kd8 43.c4 Ke8 44.b5 [44.c5! looks to take out the b-pawn (c5-c6), then the a-pawn, then make a queen.] 44...Kd8 45.bxa6 bxa6 White: 0:14.3, Black: 2:36 46.c5! [46.Kf2! even better] 46...Rxf1+ 47.Bxf1 dxc5 48.Kf2 c4
MIOnlineOct23_1273
(Black wouldn't have had this if he'd played 46.Kf2 first) 49.Kg2?? White has played such a fine strategic endgame, only to trip up at the finish line. [49.Bxc4 Ra1 (49...Rc1 50.Bf1) 50.Rh8+ Kd7 51.Rxh2 Rxa5 52.Rh6 is pretty routine.] 49...Rg1+ 50.Kf2?! [50.Kxh2 Rxf1 51.Rh6 is a try, but it looks like Black takes it with 51...c3 52.Rc6 Re1 53.Rxc3 Rxe4] 50...h1Q 51.Rxh1 Rxh1 52.Bxc4 Ra1 53.Bxa6 Rxa5 This is a technical win. Black is down to 1:31 (White 11.1 seconds!) but that is plenty of time to claim the win. 54.Bb7 Ke7 55.Ke3 Ra3+ 56.Ke2 Kd6 57.Bc8 Kc5 58.Bf5 Kd4 59.Kd2 Ra2+ 60.Kc1 Kc3 61.Kb1 Rg2 62.Be6 Kd2 63.Bf5 Kc3 64.Be6 Rd2 65.Bf5 Rd4 66.Kc1 Ra4 67.Kb1 Kd2 68.Kb2 Rb4+ 69.Ka3 Kc3 70.Bg6 Rb8 [70...Rb6] 71.Ka4 Kc4 72.Ka3 Rb6 73.Bf7 Kc3 74.Ka4 Rd6 75.Kb5 Kd4 76.Be6 Kxe4 77.Kc5 Kf4 78.Bg8 Rh6 79.Be6 e4 80.Kc6 e3 81.Kxc7 e2 82.d6 Rxe6 83.d7 Re7 84.Kd6 Rxd7+ A difficult struggle with interesting phases, marred by a game-turning blunder leading to an upset win by Adam. If Eric only had more time he surely would have brought it home. 0-1

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 The sharpest line of the Najdorf. It's good to see this classic battle played again. 6...e6 7.f4 Be7 8.Qf3 Qc7 9.0-0-0 Nbd7 10.f5!? Mike likes this direct move and has scored well with it. 10...e5 [Black may wish to keep the pawn on e6 to cover the light squares and try 10...Ne5 11.Qh3 Nfg4 12.Bxe7 Qxe7 (not 12...Nf2? 13.Nxe6!!) 13.Qg3 0-0] 11.Nde2! b5 12.Bxf6 Nxf6 13.Nd5 Nxd5 14.exd5! An interesting plan to open the e4 square for the white knight. This is much more dangerous than it looks at first sight. 14...0-0?! [14...Qc4 15.Kb1 Bd7 16.Nd4 Qc5 could be an improvement. The black king will then have a choice which of place on the board is safest.] 15.Ng3 Bd7?! [15...b4!? 16.Ne4 f6 17.g4 Bd7 18.Kb1 a5 19.h4 looks dangerous, but Black should also get some chances for attack.] 16.Ne4 f6 17.c3!

MIOnlineOct23_1249
17...a5 18.g4 White can close up the queenside against any pawn advance but Black can't stop the white pawn storm on the kingside. So Black needs to do something to alter the course of the game, but it's not easy. 18...b4?! 19.c4! a4 20.Bd3 Rac8 21.h4 Qb6 22.Kb1 White is now in complete control. There is no breakthrough for Black on the queenside and White can calmly prepare the kingside breakthrough. 22...Rb8 23.Rdf1 b3 24.a3 Qd4

Color Allocation

US Chess Rules of Chess 29E addresses how tournament directors should assign colors to players in any given round. It is a complicated and tough subject, so no surprise the matter is discussed and detailed out in almost 10 pages. While I’m not going to try to summarize and cover all aspects, recent chat discussions in the live twitch broadcast prompted to point out some of the basic, easier and regularly used guidelines.

Two Principle Guidelines

1)The objective in a tournament with an even number of rounds is to give white and black the same number of times to as many players as possible; in an event with an odd number of rounds, each player should receive no more than one extra white or black above an even allocation.

2)In addition to the task of equalizing colors, the director, after the first round, tries to alternate colors, by giving as many players as possible their due (correct or expected) color, round by round. The due color is usually the color a player did not have in the previous round, but not always. For example, a player who had white in rounds one and two and black in round three has a due color of black in round four, as equalization has priority over alternation.

First round colors in the top section is decided usually by coin toss. Consecutive sections are determined based on the open section. As many players as possible are given their due colors in each succeeding round, so long as the pairings conform to the basic Swiss system rules.

 

What’s a due color?

A player who has had an unequal number of whites and blacks is due the color that tends to equalize the number of whites and blacks. A player who has had an equal number of whites and blacks is due the opposite color to that he received in the most recent round. Unplayed games, including byes and forfeits, do not count for color. This means forfeit wins, and byes!

 

So what’s the priority? Equalizing the number of whites and blacks? Or Alternating the colors?

Equalization of colors takes priority over alternation of colors. First, as many players as possible are given the color that tends to equalize the number of times they have played white and black. After that is accomplished, as many players as possible should be given the color opposite to that which they played in the previous round.


What about pairing players due the same color?

1.If one player has had an unequal number of whites and blacks, while the other has had equal colors, the player who has had unequal colors gets due color. Example: WBW gets black over BxW, where x denotes any unplayed game—full-point bye, half-point bye, forfeit win, forfeit loss, etc.

2.If both players have had an unequal number of whites and blacks, the player with the greater total color imbalance gets due color. Example: WWBW gets black over xWBW.

3.If both players have had an equal number of whites and blacks, or both are equally out of balance, and if they had opposite colors in the previous round, the players should be given colors opposite to that which they played in the previous round. Example: WWB gets white over WBW.

4.If both players have had an equal number of whites and blacks, or both are equally out of balance, and if they had different colors in one or more prior rounds, priority for assigning color should be based on the latest round in which their colors differed. One or both players should be assigned the color opposite to that which they played in that round. Example 1: WBWB gets white over BWWB, because the first player had black in round two, the latest round in which colors differed. Example 2: BWxBW gets white over BWBxW, because the first player had black and the second had no color in round 4, the latest round in which colors differed.

5.If both players have had the same color sequence, the higher-ranked player gets due color. The higher ranked player is the player with the higher score. If the players have the same score, the higher-ranked player is the higher-rated.

Application of these Rules in Recent Matches

Applying these rules, we can understand why IM Elliott Winslow got black in Round 6 against GM Gadir Guseinov. Elliott had BWBWB going into Round 6, while Guseinov had HHBWB. Since they both had BWB in the last three rounds, going back Elliott had W in Round 2, while Guseinov had no color in Round 2. This means Elliott was equalized at that point, and Guseinov had a color imbalance.

Take on the Mechanics' Chess Staff Live on Twitch!

The chess room staff at the Mechanics' Institute are taking on all comers now weekly, as each of us will live stream an arena tournament where we will commentate our own games! You might be playing 3-time US Champion GM Nick de Firmian, or perhaps our commentator and instructor extraorinaire FM Paul Whitehead. Try to take down Organizer sensation Dr. Judit Sztaray or Chess Director Abel Talamantez. We will all be live on Twitch playing, reviewing about our games, and talking about anything that comes up in the chat. Come hang out with us at the Mechanics' online club, perhaps we may even give out an occasional free prize!

Arenas are an hour long, and the chess staff will be paired against the first available player to play at the conclusion of their games. All other players will be paired with the next available opponent. This will continue for the whole hour. While there is no guarantee you will be paired against a chess staff member, you will have a very good chance at it, depending on the number of players playing. All games will be streamed live on our Twitch channel: https://www.twitch.tv/mechanicschess

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 This classic line of the Guico Piano has been played for centuries. The action in the center is complicated though now the right plans have been found so that Black can fully equalize. 6.0-0!? an unusual move that sets problems for Black. It may not objectively be so good but it has a lot of practical value (and it's fun). [6.cxd4 Bb4+ 7.Bd2 Bxd2+ 8.Nbxd2 d5 9.exd5 Nxd5 is the standard old line that is safe and equal] 6...dxc3?! [The right pawn to take is the trouble making e-pawn - 6...Nxe4! 7.cxd4 (7.Re1?! d5 8.cxd4 Bb4 9.Bg5 Qd6 10.Nbd2 f5) 7...d5 8.dxc5 dxc4 9.Qe2 Qd3 solves all of Black's troubles and leaves White the task of trying to regain the sacrificed pawn.] 7.e5! Ng8? [The only way out of trouble now is 7...d5! 8.exf6 dxc4 9.fxg7 Rg8 is still ok for Black. The game would have equal chances.] 8.Qd5! Qe7 9.Nxc3 White's developmental lead is a decisive advantage He controls the whole center and has open lines for the one pawn given up. 9...Nh6 10.Nb5 [10.Bg5 Qf8 11.Nb5 Bb6 12.Nd6+! cxd6 13.Rfe1! dxe5 14.Rxe5+ wins right away] 10...0-0

Domination Part 8

[email protected]

 

This week’s studies take us to the material imbalance of rook and knight vs. queen, with her majesty chased, trapped – dominated.  I suspect she will take her revenge soon enough, however.

These studies have immense practical value.  Without moving the pieces, you can work on visualizing forced sequences, witnessing the birth of creative ideas and thought, spurring your own investigations into the mysteries of chess.

Again, the examples are taken from Domination in 2,545 Endgame Studies by Ghenrikh Kasparyan (1974).

-------------------------------------------------------------------------------------------------------------------------------

1. Rinck 1903 – White wins.

This is our model, and the solution is precise, elegant: 1.Rb4! Qe8 (1...Qa5 2.Nc6+ wins) 2.Rb8! Relentless. The queen has but one square. 2…Qh5 3.Rh8!  Incredible, but true. 3…Qxh8 4.Ng6+. The knight has the last word. White wins.

-------------------------------------------------------------------------------------------------------------------------------

2. Troitzky 1910 – White wins.

With Rinck’s study – and solution - in mind, this won’t be too difficult, but of course there’s a nice twist or two along the way.

-------------------------------------------------------------------------------------------------------------------------------

3. Kubbel 1911 – White wins.

You have your rook and knight: use them!

-------------------------------------------------------------------------------------------------------------------------------

4. Lilja 1962 – White wins.

Finally, I’ll leave you with this mind-bending study: enjoy!

-------------------------------------------------------------------------------------------------------------------------------


GM Nick de Firmian's Column

The Old Man and the Endgame

Excuse the reference to Ernest Hemingway’s classic novel, yet this week we must consider the “old men” of the game of chess who take refuge in the endgame. Tournament players know of the terror of playing an up and coming young kid. The youngsters are sharp with the tactics, know their openings extremely well and can navigate the middle game. Yet they are often lacking in endgame skills, which is something one acquires with experience. The older player will sometimes seek to bail out of a bad position into an inferior endgame that can be held for a draw. Older players (particularly older masters) will often play a safe opening and middlegame against a young opponent but then seek to grind down the youngster in a dry ending where they figure they will have the chances.

Below we have three examples of endgames and in these the older player wins, as often happens. One reason for our nod to the “old men” is last week’s US Senior Championship which was won by GM Joel Benjamin (a former US Junior Champ and 3-time US Champion). We must remind you that age is relative and so the question is, are you older than your opponent? If so you may wish to head to the endgame and we hope these examples give you some ideas.

(1) Firouzja,Alireza - Carlsen,Magnus [A04]
Altibox Norway Chess, 18.10.2020

Here we have the young super talent - 17 year old Alireza Firouzja - meeting the "old" champ. 1.Nf3 Nf6 2.g3 c5 3.Bg2 Nc6 4.0-0 e5 5.e4 d6 6.c3 g6 7.d4 cxd4 8.cxd4 Bg4 9.dxe5 dxe5 10.Nc3 Bg7 11.h3 Bxf3 12.Qxd8+ Rxd8 13.Bxf3 0-0 The game is an equal ending. Young Firouzja was likely happy to have a safe draw against the champ. Yet it is the endgame, and Magnus loves to try to grind things out. 14.Kg2 Nd4 15.Bg5 h6 16.Bxf6 Bxf6 17.Nd5

ColumnOct21_1241
17...Rd6 It really looks like the game is headed for a quick draw. How can one get chances in this symmetrical, bishops of opposite color position? 18.Rac1 Bd8 19.Rfd1 Kg7 20.Ne3 Ra6 21.a3 h5 22.Nc4 Bf6 23.h4 Rc8 24.Ne3?! a safe looking move, but the retreat begins to give Black an initiative. There was a forcing variation - [24.Rxd4! exd4 25.e5 Rc7! 26.exf6+ Kxf6 27.Rc2 d3 28.Rc3 b5 29.Ne3 Rxc3 30.Nd5+ Ke5 31.Nxc3 Rb6 32.Nd5 Rd6 33.Nc3 should hold the draw] 24...Rac6 25.Rxc6 Rxc6 26.Rd3 Bd8 27.Bd1 Rc1 Magnus has gained a small advantage with control of the c-file. Of course he continues to press. 28.Bb3 b5 29.Rd1 Rc8 30.Ba2 a5 31.Rd3 a4! 32.Kf1 Bb6 33.Rc3?! This trades the rooks but weakens the queenside pawns. Black's advantage now becomes serious. 33...Rxc3 34.bxc3 Nb3! 35.Ke1 Bc5 36.Nc2 Nc1?! too eager to grab a pawn, Magnus allows the game to become simplified. He would have kept a lot of pressure with [36...f5 e.g. 37.f3?! f4! 38.gxf4 exf4 39.Kf1 Be7] 37.Bd5 Nd3+ 38.Ke2 Nxf2 39.Bc6 The queenside pawns will be liquidated. 39...f6 40.Ne3 Nh1 41.Nf1 Bxa3 42.Bxb5 Bb2 43.Bxa4 Bxc3 44.Kf3 Bd4 45.g4 hxg4+ 46.Kxg4
ColumnOct21_1242
All the pawns are on the kingside and there are bishops of opposite color. White has very good drawing chances. 46...Nf2+ 47.Kf3 Kh6 48.Ng3 Nd3 49.Be8 Nf4 50.Ne2 Ne6 51.Bf7 Nc5 52.Ng3 Bc3 53.h5! Be1! 54.Bxg6 Bxg3 55.Kxg3 Kg5 56.Kf3 Nb3 57.Bf7 Nd4+ 58.Kg3 Ne2+ 59.Kf3 Nf4 60.Kg3 Nxh5+ 61.Bxh5 Kxh5 62.Kh3 so Black has won the h-pawn and has 2 pawns vs one in the king ending. Yet the game is a draw because White has the opposition. Magnus knew this, and Firouzja also figured on the draw. Yet Magnus will be as tricky as he can be to try to take the full point. Can you dear reader hold the draw in this position? Think opposition, and especially distant opposition. 62...Kh6 63.Kh4 Kg7 64.Kg3 very good so far. White keeps the kings doing the dance with the right number of squares in between. He must be ready to close in when the black king advances, but in a way that White keeps the opposition when the kings are one square apart. 64...Kf8 65.Kf2 Ke7 66.Ke2 Ke8 67.Ke3 Kd7 68.Kd3! Kd6 69.Kc3? Oh no! The wrong square. The youngster fails at the finish. 69. Kd2 Kc5 70. Kc3 holds the game. 69...Kc5
ColumnOct21_1243
Now White must give way with the king. 70. Kd3 Kb4 or 70. Kb3 Kd4 wins easily, so Firouzja resigned. 0-1

 

(2) Carlsen,Magnus - Aronian,Lev [D35]
Altibox Norway Chess, 18.10.2020

When Magnus was quite young Aronian was already a veteran player. Back then he taught Magnus a thing or two in the endgame, though of course Magnus learned his lesson well. In the recent Altibox Norway Chess tournament Magnus played Aronian in the last round (when the champ has already won the tournament). The final game was like the old days with the older Aronian getting an endgame advantage. 1.Nf3 d5 2.d4 Nf6 3.c4 e6 4.Nc3 Be7 5.cxd5 exd5 6.Bf4 c6 7.Qc2 g6 8.e3 Bf5 9.Bd3 Bxd3 10.Qxd3 Nbd7 11.h4 a5 12.Kf1 a4 13.a3 Qb6 14.Qc2 h5 15.Bg5 0-0 16.Ne5 Rfe8 17.Bxf6 Nxf6 18.Rh3 Qb3

ColumnOct21_1244
The game is level and would remain so if White just trades queens on b3. Magnus retreats and gets a disadvantage. We will fast forward to the endgame to focus on our theme. 19.Qb1 Ne4! 20.Nxe4 dxe4 21.Qxe4 Bd6 22.Rg3 Bxe5 23.dxe5 Qb5+ 24.Kg1 Rxe5 25.Qd4 Rd5 26.Qf6 Rf5 27.Qd4 Qe2 28.e4 Rb5 29.Rb1 Qc2 30.Qd3 Rc5 31.Qxc2 Rxc2 White is somewhat tied down in the double rook ending as must play for the draw. 32.b3 b5 33.Rd3 axb3 34.Rbxb3 Ra4 35.Rdc3 Rc4 36.Rxc2 Rxc2 37.f3?! Kf8 38.Kh2 Ke7 39.Kh3 Ke6 40.Rd3 Rc4 41.Kg3 Ke5 42.Rd7 Rc3 [42...Ra4!] 43.Ra7 f6 44.Ra8 Kd6?! [44...Kd4!] 45.Kf4 Kc7 46.g4 Kb7 47.Rg8 hxg4 48.fxg4 Rxa3 49.Rxg6 b4 50.Rxf6? Here Magnus goes wrong with a greedy move. He loses a critical tempo in the race to queen and we can't blame it on his youth this time. Aronian is not quite the player he was ten years ago, but his endgame play is still the highest level and he can take down Magnus when given the opportunity. [50.Rg7+ Kb6 51.Rg8 c5 52.g5 would hold the draw] 50...b3 51.Rf7+ Kb6 52.Rf8
ColumnOct21_1245
52...Ra7! Now the black pawns are just too fast. 53.Rb8+ Rb7 54.Rd8 c5 55.Ke3 c4 56.Rd1 [56.Kd2 b2 57.Kc2 b1Q+ 58.Kxb1 Kc7+ picks up the white rook] 56...c3 57.Rb1 Kc5 58.Kd3
ColumnOct21_1246
White resigns. 58...Kb4 supports the black pawns and they easily advance. 0-1

 

(3) Benjamin,Joel - Wolff,Patrick [B50]
US Senior Chp., 18.10.2020

The winner of the US Senior Championship was Joel Benjamin of New Jersey. Here he meets the MI's own Patrick Wolff, who had a very respectable showing in the championship. 1.e4 c5 2.Nf3 d6 3.Bb5+ Joel chooses a quite opening, planning to play for small advantages. 3...Bd7 4.Bxd7+ Nxd7 5.0-0 Ngf6 6.d3 g6 7.Re1 Bg7 8.c3 0-0 9.d4 cxd4 10.cxd4 e5?! This gets a pawn stuck on e5 and so makes the fianchettoed bishop less valuable. [10...b5!? would get some queenside space] 11.dxe5 Nxe5 12.Nxe5 dxe5 13.Nc3 Qb6 14.Qe2 Rfc8 15.Bg5 Bf8 16.Bxf6 Qxf6 17.Nd5

ColumnOct21_1247
This strong knight on d5 ensures White a small but enduring advantage. 17...Qe6 18.Rac1 Rxc1 19.Rxc1 Rc8 20.Rc4 Kg7 21.Qc2 Rxc4 22.Qxc4 Qc6 23.Qxc6! Headed to a knight versus bishop ending where the knight is a little better. Benjamin is going for the slow squeeze. 23...bxc6 24.Ne3 Kf6 25.Nc4 Ke6 26.Kf1 Bc5 27.Ke2 Bd4 28.f3 h5 29.b3 h4 30.h3 All the white pawns are on light squares where the black bishop cannot attack them. Clearly White is better and pushing for the win. The question is whether he is able to make progress. 30...Bc5 31.Kd3 Bb4 32.a3 Bc5 33.b4 Be7 34.Na5 Kd6 35.Kc4 Bg5?! [35...Kd7 would keep better drawing chances. The bishop is good guarding from e7.] 36.Kb3 [36.b5! cxb5+ 37.Kxb5] 36...Kd7 [36...Bd8!] 37.Ka4 Be3 38.Nc4 Bd4 39.Ka5 Kc7?! The best plan now was to go completely on the offensive! [39...Ke6 40.Ka6 Kf6! with the plan of marching the black king down to take the g2 pawn.] 40.Ka6 f6 41.a4 Bf2 42.b5 Bd4? [Black had one last chance to draw - running with the king to the kingside while White grabs the a-pawn: 42...cxb5 43.axb5 g5 44.Na5 Kd6! 45.Nc6 Kc5! 46.Nxa7 Kc4 47.b6 Bxb6 48.Kxb6 Kd3 49.Kc5 Ke3 50.Nc6 Kf2 51.Kd6 Kxg2 52.Ke6 Kxh3 53.Kxf6 g4 54.fxg4 Kxg4 55.Nxe5+ Kf4 56.Ng6+ Kxe4 57.Nxh4 and all the pawns are gone] 43.Na5 cxb5 44.axb5 Kb8 45.Nc6+ Ka8
ColumnOct21_1248

46.Nxa7! This clever move crashes through right away. 46...Bxa7 47.b6 f5 [47...Bb8 48.b7#] 48.bxa7 1-0
