The November edition of the Tuesday Night Marathon Online kicked off with rounds 1&2 on Tuesday with close to 50 players. This is a great turnout considering that of this writing we have more than 30 players registered for the new Thursday Night Marathon beginning this week. The competition in the top section will be fierce, as GM Gadir Guseinov and GM James Tarjan are entered, as well as Mechanics' powerhouse players IM Elliott Winslow and FM Kyron Griffith.
The first rounds saw some entertaining action, with FM Kyron Griffith having to pull off two escapes that would have made David Blaine proud. GM Jim Tarjan used a nice tactical shot in his first game, then used GM technique in his second. Also with two wins were GM Guseinov, IM Winslow, NM Mike Walder, NM Arun Dixit, and Ethan Guo.
In the u/1800 section, Phillip Gerstoft, Bryan Hood, Pranav Pradeep, and Sebby Suarez remain perfect with 2/2.
It was an entertaining start for the new TNM this month as we were joined on the broadcast by WIM Dr. Alexey Root. The exciting games and great commentary by Alexey and FM Paul Whitehead enhanced a terrific evening for chess. Special kudos as always to tournament director Judit Sztaray, who paired the games manually on chess.com.
Here are some games from the evenings action, annotated by GM Nick de Firmian.
(1) FM Kyron Griffith (KyronGriffith)(2220) - Jonah Busch (Kondsaga)(2070) [C06]
MI November TNM Chess.com (1), 10.11.2020
1.e4 e6 2.d4 d5 3.Nd2 The Tarrasch Variation is positionally safer than the strange positions that arise from the Winawer Variation (3. Nc3 Bb4 4. e5). It leads to more normal positions which are more straightforward to play. 3...Nf6 4.e5 Nfd7 5.Bd3 c5 6.c3 Nc6 7.Ne2 cxd4 8.cxd4 f6 9.exf6 Qxf6 The less common recapture on f6. The black queen is developed but also somewhat exposed. 10.Nf3 h6 11.0-0 Bd6 12.Be3 0-0 13.Qd2 e5 14.dxe5 Ndxe5 Black has gotten his pawn break with freedom of action for his pieces yet has the isolated d-pawn. 15.Nxe5 Bxe5 [15...Qxe5 16.Ng3 d4 17.Bxh6! is very good for White.] 16.Bc5 [White should consider 16.Rad1 as 16...Bxb2?! 17.Nf4 is great compensation for the pawn] 16...Rd8 17.Rab1 b6 18.Be3 d4 19.Bf4 Bf5
One must consider the opening a success for Black. All of the pieces are out and the isolated d-pawn looks like a strong passed pawn. 20.Bxe5 Nxe5 21.Bxf5 Qxf5 22.Ng3 Qg6 23.Rfe1 Rac8 Natural development, but [23...Rd5! followed by Rad8 would force White to deal with the powerful passed pawn. Black would have the edge and an easy game to play.] 24.Rbd1?! Letting the black rook invade with tempo [24.Re4! Nc4 25.Qd3 is about equal] 24...Nc4?! [24...Rc2 25.Qb4 Qf7 26.f3 Nc4 would be a strong initiative for Black] 25.Qf4 Nxb2 26.Rxd4 Rxd4 27.Qxd4 Nd3 28.Rd1 Nc5 everything is back to equal with no weakenesses for either side 29.h4 Qe6 30.a3 Re8 31.h5 Re7 32.Qf4 Rd7 33.Rxd7 Qxd7 34.Kh2 Qf7 35.Nf5? Kyron just gives a pawn away. 35...Qxh5+ 36.Nh4 Qf7 [36...g5 37.Qb8+ Kf7 38.Qxa7+] 37.Qg4 Kh7 38.f4 Ne6 39.f5 Ng5 40.Ng6 Objectively Jonah should be winning the position with the extra pawn. Kyron is being tricky with the knight on g6, creating mating possibilites. 40...b5?! [40...Qc7+! 41.Kh1 (41.g3 Qc2+) 41...Qc1+ 42.Kh2 Qxa3 is two pawns ahead] 41.Qf4 a5?! [41...a6] 42.Qe5! b4 43.axb4 axb4 44.Qc5! b3 45.Qc8
45...Qxf5?? panic. Black could defend the mate with [45...Qg8 when White needs to make a draw by repeating with 46.Nf8+ Kh8 47.Ng6+] 46.Qxf5 b2 47.Ne7+ Kh8 48.Qf8+ Kh7 49.Qg8# KyronGriffith won by checkmate. 1-0
(2) Chelsie Zhou (mwncklmann)(1886) - GM Jim Tarjan (Tirantes)(2407) [A53]
MI November TNM Chess.com (1), 10.11.2020
1.c4 e5 2.g3 d6 3.Bg2 Nf6 4.Nc3 Be7 An unusual and straightforward development against the English. Tarjan makes his opponent figure out the best strategy against this unpretentious set-up. 5.e3 [5.d4! Hits quickly at the center to give White more freedom of action.] 5...0-0 6.Nge2 c6 7.d4 Re8 8.0-0 Bf8 9.b3 Choosing a middle game battle. The ending after [9.dxe5 dxe5 10.Qxd8 Rxd8 would be very comfortable for Black.] 9...e4! 10.d5 c5 11.Bb2 Bf5 12.Qd2?! This starts to turn the advantage over to Black. White needs to address the control that Black is getting over the kingside light squares. [12.h3 was called for] 12...Nbd7 13.Nf4 Ne5 14.Qc2 Qd7
It looks like the e-pawn is hanging, but do you think the great Tarjan has just made a mistake? 15.Nxe4? Chelsea grabs the pawn, but this loses. He was already under pressure with the black pieces looking to infiltrate on the kingside. 15...Nxe4 16.Bxe4
16...Nf3+! Cute. The white bishop on e4 is pinned and Black wins a piece. The game is over. 17.Kh1 Bxe4 18.Qd1 g6 19.Qc1 Bh6 20.Qc3 Re5 No checkmate on the long diagonal. Black will play ...Bxf4 then ...Qh3 with mate to follow, so Chelsea resigned. 0-1

MI November TNM Chess.com (2), 10.11.2020
1.e4 d5 2.exd5 Qxd5 3.Nf3 [3.Nc3 and 4.d4 is still the most popular way to play, keeping open options for the king knight and avoiding early pins with ...Bg4.] While the text does the same for the other knight, where c2-c4 or c2-c3 is still possible right away. 3...Nf6 Even this knight has another option. [3...Bg4 4.Be2 Nc6 5.d4 (And pawns! Perhaps 5.0-0 0-0-0 6.h3 so as not to place a target on d4 too soon.) 5...0-0-0 certainly pressures the d-pawn. 6.Be3 (6.c4 is somewhat more common (and quite critical!),; while 6.c3 has to reckon with 6...e5!?) 6...Nh6!? when ... Nf5 has its value.] 4.Be2 Tarjan is playing the waiting game full-out. [4.d4 and; 4.Nc3 would be committing one or another.] 4...Bg4 This and the other bishop development are the lion's share of games here, but quite a few other things have been tried; after all, Black has been given free rein. 5.h3 Bh5 [5...Bxf3 6.Bxf3 Qe5+!? leads to a typical Center Counter game, maybe minus the queens. Black plays ...c6 and ...e6 and develops smoothly, hardly missing his light-square bishop.] 6.Nc3 Qd6 As usual, the queen has a selection of good retreats (but please not f5, and definitely not c6!). 7.d4 e6 8.0-0 [8.g4! Bg6 9.h4! Nxg4 10.h5 Bf5 11.Nh4 Nf6 12.Nxf5 exf5 Here White's play seems worth more than the pawn.] 8...Be7 9.Bg5N [9.Be3 is pretty much all that has been played here (somehow the game is already in rareified territory).] 9...Nc6 10.Nb5 Qd8
[10...Qd7!] White: 20:59, Black: 11.Ne5?! [11.c4!? a6 12.d5!? Bxf3 13.Bxf3 exd5 14.cxd5 Ne5 15.Nc3 0-0! isn't much for White.; 11.Bxf6!? Bxf6 12.d5! exd5 13.Qxd5!] 11...Bxe2 12.Qxe2 0-0 Played after quite a long think. [12...Nxd4?? 13.Nxd4 Qxd4 14.Qb5+ is disastrous.; But 12...a6! favorably forces the issue: 13.Nxc6 bxc6 14.Nc3 Qxd4 15.Rfd1 White has compensation for the pawn but no advantage.] 13.Rad1 Nxe5?! [13...Nd5!? 14.Bd2! Nxe5 15.dxe5 a6 16.Nc3 Nxc3 17.Bxc3 isn't much going for White; Black sidesteps, trades a rook, sidesteps the other way, trades another rook, nothing.] 14.dxe5! White: 12:41 Black: 10:28 14...Nd5 15.Bc1! Now the problems with the knight on the d-file plus less space and still kingside attack issues, should cost Black, eventually, the game. 15...a6!?
16.c4?! [16.Nd4 is a straightforward advantage, with a slight curveball after 16...c5 17.Nf5!] 16...axb5 17.cxd5 exd5 18.Qxb5 c5 19.Qxb7 d4! 20.Qb3?! [20.a3 Rb8 21.Qf3 Qd7= will take a lot of untangling.] 20...Qc7 [20...Qd7!?] 21.Rfe1 Kh8?! This gives White time to organize a break on b4 or e6. But note that Black has been taking a lot of time on every move, even the more-or-less forced ones; it's now: White: 4:43 Black: 2:37 [21...Qc6 again aiming at a4, continues to make White's progress difficult. 22.Qc4 (22.Qc2 Qg6!) 22...Qe6! when White pretty much has to trade: 23.Qxe6 fxe6 24.a3 Kf7! Again, White's extra pawn won't buy anything.] 22.Qc4 The threat of Rxd4 has Black giving up a bit more ground. 22...Rad8?
[22...Qa7 or other queen moves] 23.b4!? [23.b3! could well be better. White is able to arrange a4 without trouble on b3, and e5-e6 is still available. The computers make this a win.] 23...f6? Doing White's work for him. [23...Qb6 24.bxc5 (24.b5 Qe6!) 24...Qxc5 25.Qd3 Qd5 still requires White to make something happen.] 24.e6! [Stockfish makes 24.exf6! even better. But the psychological pressure of that passed pawn (and keeping Black without play) is never a bad idea. (And White is still comfortably within the winning range.)] White: 3:21 Black: 24...Rfe8 25.a4 [25.b5!] 25...Qc6 26.b5 Qd5 27.Qxd5 Rxd5 Black does get ...c4 in now, but when you add in the pawn on e6 and the tricks with Black getting mated on the bank rank, it's pretty bad. 28.Bf4?! [28.b6! does work: 28...c4 29.Bb2 (29.Bd2) ] 28...Bd6? [28...c4; or better yet 28...g5 29.Bd2 c4 puts up some fight, although White should prevail.] 29.Bxd6 Rxd6 30.Rc1 Rd5 31.b6 d3 momentarily scary! But Tarjan has seen futther. 32.Red1 White: 0:45 Black: 0:43 32...Rxe6 33.b7 Re8 [33...Rb6 34.Rb1] 34.Rb1?! [34.a5! (still eyeing Pc5) is the sudden death kick.] 34...Rb8 35.a5 Rd6
This has gotten critical! White: 0:31 Black: 0:18.5 36.a6?? [36.Kf1! c4 37.Rdc1 d2 38.Rxc4!! d1Q+ 39.Rxd1 Rxd1+ 40.Ke2 Rdd8 41.a6 Kg8 42.Rc7] 36...Rxa6= 37.Rxd3
37...Ra7?? [37...h5! 38.Rd5 (38.Rd7 Rc6 39.Kf1 c4 is just fast enough to hold) 38...Rc6 39.Rxh5+ Kg8 and White would get R+3 v R+2, a theoretical draw but in practice...] 38.Rd7 h6 39.Rc7 c4 40.Rc8+ Tirantes won by resignation 1-0
(4) Nicholas Weng (ninjaforce)(1934) - FM Kyron Griffith (KyronGriffith)(2224) [B15]
MI November TNM Chess.com (2), 10.11.2020
1.e4 c6 2.d4 d5 3.f3!? The Fanstasy Variation of the Caro-Kann. This is unusual as White has many other reasonable developing moves. Still, it guards the center and takes the game to unsual territory where the opponent probably doesn't remember the book lines. 3...g6 [Black has some other decent alternatives - 3...e6; 3...dxe4; 3...Qb6!?] 4.Nc3 Bg7 5.Be3 Qb6!? 6.Qd2!? [6.a3!? Qxb2?? 7.Na4 would win the queen] 6...Qxb2 7.Rb1 Qa3 8.exd5 Nf6 9.Bc4 So pawns are back to even and the postion is messy. 9...0-0 10.Nge2 b5 11.Bb3 b4?! Kyron is wanting to win a pawn, but this gives away squares and keeps the black queen on a poor square. 12.Na4 Nxd5 13.Bh6 Ba6 14.Bxg7 Kxg7 15.h4 It makes sense to go for the attack with Black undevoloped and the queen offside. 15...Nd7 16.h5 N7f6?! [16...Bxe2 17.Kxe2 e6 18.hxg6 hxg6 19.Qh6+ Kf6 looks risky but is a better defense] 17.hxg6 fxg6 18.Qh6+ [18.Nc5!] 18...Kh8 19.Ng3 Bc4?
20.Nc5 [20.Ne4! Bxb3 21.axb3 Qa2 22.Rc1 Qa3 23.Nxf6 Nxf6 24.Ke2 would be a winning position as Black will lose his queen to Ral (24...Qa2 25. Qd2).] 20...Bxb3 21.axb3 Qa2?! 22.Kd2! Rg8 23.Ne6 White is back to a winning postion. 23...Nh5 24.Nxh5 [24.Ne4! is even better, but White is still winning] 24...gxh5 25.g4! Nf6 26.Qe3 Qa5 27.g5 Qf5 [27...Ne8 28.Rxh5 Ng7 29.Rxh7+! Kxh7 30.Rh1+ Kg6 31.Rh6+ Kf7 32.Nxg7 is a winning attack] 28.Rbg1 [28.gxf6 Rg2+ 29.Ke1 is a little messy though should still win] 28...Nd5 29.Qe4 Qxe4 30.fxe4 Nc3 31.Ke3 Rg6 32.Nf4
Well played by Nicholas. Black is on the verge of collapse and Kyron decides to try something tricky. 32...e5!? 33.dxe5 Re8 34.Rxh5 Kg8 35.Nxg6 hxg6 36.Rh6 Kg7 37.Rg4 Rxe5 38.Rh2 a5 39.Kd4 Re8 40.Rf2 c5+ 41.Kc4 Nxe4 42.Rff4 Nc3 43.Kxc5! Rc8+ 44.Kb6 Nd5+ 45.Kb7 Rc7+ 46.Kb8 Rxc2 47.Rd4 Still we have a completely winning ending for White. The g5 pawn keeps the black king in a mating net against the two white rooks 47...Rc5 48.Rge4 Rb5+ 49.Kc8 Kf7 50.Re5?? [50.Kd8 Rb8+ 51.Kd7 would just be winning for White. Nicholas makes a blunder in extreme time trouble.] 50...Ne7+ KyronGriffith won on time. In fact Black now has a winning rook ending after 51. Rxe7+ Kxe7 as the g-pawn falls. Quite a comeback from Kyron, but certainly a tradgedy for Nicholas Weng. We expect good things from him to come! 0-1

1.d4 Nf6 2.c4 g6 3.f3 A fairly popular way to avoid the standard Gruenfeld lines, although it commits White to a Saemisch structure against the King's Indian. 3...Bg7 [Plenty of players still go for the Gruenfeld idea, but after 3...d5 4.cxd5 Nxd5 5.e4 Black has to retreat the knight: 5...Nb6 6.Nc3 Bg7 7.Be3 Still this has been wildly popular at the highest levels, including with Carlsen involved.] 4.e4 d6 [4...0-0 5.Nc3 Nc6!?] 5.Nc3 0-0 6.Nge2 [6.Be3 Nc6 (6...a6 7.Qd2 Nc6 0-1 (32) Muir,A (2285)-Ivanov,I (2500) Swansea 1987) 7.Nge2 0-1 (41) Valbuena Mota,A (2072)-Roa Alonso,S (2383) Galapagar 2005] 6...a6 7.Be3 Nc6 8.Qd2
The main line of the Saemisch Panno, but now Black does something different. 8...Bd7!? First seen at a high level almost 60 years a couple times by Taimanov against Polugaevsky and Petrosian. But he (Taimanov) had already played 8...Rb8, and later played that again as well. Everything was an experiment back then! [8...Na5!? was played in a game by Igor Ivanov, then was hardly seen for 18 years -- and then became quite popular. It's certainly worth a look! 9.Nc1 (9.Nf4!? b5 10.h4!? Nd7 11.h5 e5 12.Nfd5 exd4 13.Bxd4 Ne5 14.hxg6 fxg6 15.cxb5 axb5 16.Rd1 Nac6 17.Be3 b4 18.Nb5 Rxa2 19.Bh6 Bxh6 20.Qxh6 Rf7 21.Qc1 Be6 22.f4 Bxd5 23.exd5 Qe7 24.Be2 1-0 (48) Shankland,S (2671)-Patel,A (2410) Greensboro 2017) 9...e5 10.d5 c5 11.dxc6 bxc6 12.b4 Nb7 13.Nb3?! (13.Be2 and just get castled) 13...a5 14.a3 Be6 15.Rd1 axb4 16.axb4 Nd7! 0-1 (32) Muir,A (2285) -Ivanov,I (2500) Swansea 1987; 8...Rb8 is the main line, which has been deeply investigated. The latest big thing is 9.Rc1!? , a positional approach, intending a) Past fads include 9.Nc1; b) 9.Rd1; c) 9.h4!? h5 10.Nc1 (10.0-0-0; 10.Rc1!?) 10...e5 11.d5 Nd4 12.Nb3 (12.N1e2!?) 12...Nxb3 13.axb3 is similar to the game, but the difference shows itself in Black's main move 13...c5; 9...Bd7 (9...b5? 10.cxb5 axb5 11.Nxb5) 10.Nd1 b5 Black players have fished around: (10...Re8; 10...e6) 11.c5 Obviously this is highly sophisticated maneuvering, but Black still isn't sure how to handle it.] 9.h4 White fires the first shot to soften up Black's king position. [The even more blunt 9.g4 has a minus score.; 9.Nc1 was the standard plan for a while; 9...Nh5!? (and 9...e5 was the straightforward response at first; 10.d5! left Black unhappy going either forward or back.(10.Nb3) ) 10.Nb3?! Again this. (10.N1e2!?; 10.d5!?) 10...e5 (10...a5 11.d5 Ne5 12.Be2 f5 13.exf5 gxf5 14.f4 Ng4 15.Bxg4 fxg4 16.0-0 g3 17.h3 c5 0-1 (37) Vovk,Y (2611)-Smirin,I (2658) Kishinev 2016) 11.d5 Ne7 12.0-0-0 f5 13.Kb1 b6 was a protracted draw by Guseinov a few years ago: 14.a3 Kh8 15.Bd3 Ng8 16.Nc1 Rf7 17.exf5 gxf5 18.N1e2 Nhf6 19.g3 Qf8 1/2-1/2 (62) Karthikeyan,P (2497)-Guseinov,G (2645) Porticcio 2017] 9...h5 [9...b5 10.h5 bxc4 (10...e5 led to a friendly repetition: 11.Nd5 bxc4 12.Nxf6+ Bxf6 13.d5 c3 14.Nxc3 Nd4 15.0-0-0 Qe7 16.Kb1 Rfb8 17.Ne2 Nb5 18.Nc3 Nd4 19.Ne2 Nb5 20.Nc3 1/2-1/2 (20) Levitt, J (2455)-Lawton,G (2365) Southampton 1986) 11.hxg6 fxg6 12.Nf4 e6 13.Bxc4 d5 was a quick and early win by a very famou player: 0-1 (23) Andersson, B-Botvinnik,M Stockholm 1962] 10.Nc1
[10.Rc1 was played against Bay Area youthful star Christopher Yoo, who got into trouble and lost: 10...Rb8 11.Nd1 b5 12.c5 The modern plan although usually without h4/ h5. 12...Re8 13.Nf2 e6 14.Bg5 e5 15.d5 Nd4 16.Nxd4 exd4 17.c6 Bc8 18.Be2 Re5 19.Nd3 Re7 20.Nf2 White offers a repetition here also, but Yoo avoids. 20...Qe8 21.Kf1 Re5 22.Nd3 Re7 23.Re1 Kh7 24.g3 Qh8 25.Kg2 Re8 26.Nf2 Kg8 27.Bd3 Nh7 28.Bf4 b4 29.a3 bxa3 30.bxa3 1-0 (45) Kelires,A (2508)-Yoo,C (2414) Heraklion 2019] 10...e5! The standard opening combination 11.d5 Nd4 12.Nb3 Nxb3 [Another common sequence was the only other game here: 12...c5 13.dxc6 bxc6 14.Nxd4 exd4 15.Bxd4 Re8 Sometimes this blows up in White's center, but more usually Black can't quite get enough for the pawn. Here the higher rating prevailed: 16.Be2 Rb8 17.Rd1 Be6 18.0-0 c5 19.Be3 Nd7 20.f4?! Qxh4 0-1 (41) Valbuena Mota,A (2072)-Roa Alonso,S (2383) Galapagar 2005] 13.axb3 Nh7N keeping an eye on g5 and, frankly out of the way. 14.b4 f5 15.c5 Both sides expand on the side where they have prospects. 15...Kh8 A sort of "wait and see" strategy -- but Guseinov is already envisaging the game's ultimate path. 16.Bd3 Qe7+/=
Black stands ready to go right or left depending on where White's king ends up. 17.cxd6? Opening the c-file, but for whom? The possibility of c5-c6 was worth keeping as an option. [17.Ra5!?] 17...cxd6= It is hard to find a specific progress for White on the queenside. Stockfish pretty clearly doesn't know what to do for White (moving to and fro), and makes it the usual "0.00." 18.Na4?!
The initiative on the queenside slips away -- while Black still has his kingside chances. [18.Ra3] 18...Bxa4! 19.Rxa4 Rac8?! [19...Nf6!=/+ 20.Bg5 (20.0-0 fxe4 21.fxe4 Qd7 22.b5 Ng4) 20...Qd7 picks up time on the rook 21.Bxf6!?

[21...fxe4 22.fxe4 Nf6 provokes White to trade on f6, when again the dark squared bishop finally emerges.] 22.0-0 [22.Bd3+/=] 22...f4!? 23.Bf2 Bf6 Black methodically prepares the opening of the g-file. 24.Rc1 Rxc1+?! [24...g5!? 25.Rac4 Rxc4 26.Rxc4 gxh4] 25.Qxc1 g5 26.Rc4 gxh4 27.Rc7 White is getting something going. 27...Qg6
White: 11:17 Black: 26:22 (Guseinov is hardly taking any time for the whole game!) 28.Bd7?! Very sensible looking! But Black can stymie White. [28.Kh2!? Rg8 and now Stockfish likes 29.Qh1!!] 28...Rg8 29.Qf1 [29.Bh3? Ng5-+] 29...Qg7!
The critical moment! 30.Bb6??

Before going into the annotations, Kristian Clemens sent us an email with the following comment regarding his game:
I spent three minutes on my 19th move, 19. c5, because I realized it would involve sacrificing a pawn, and as some old master once said, it can be harder to sacrifice a pawn than a queen. While I was trying to gather the courage to make the move, I remembered reading a great article on chess.com by Greg Serper in which Serper remembered analyzing a game with his mentor Mikhail Botvinnik (https://www.chess.com/article
My favorite part of Kramnik's game was when he sacrificed a pawn with 30. Nc4! and 31. b5!, setting up a perfect light-square blockade. (I can't seem to paste a diagram, but here's the game: https://www.chessgames.com/per
1.Nf3 Nf6 2.c4 g6 3.d4 Bg7 4.Nc3 0-0 5.e4 d6 6.Be2 e5 7.d5 The Petrosian System against the KIng's Indian. The late world champion would simply take the advantage in space with the advanced d-pawn. 7...a5 8.Bg5 h6 9.Bh4 Na6 10.0-0 Qe8 11.Nd2 Nh7 12.a3 h5 13.f3 f5
14.Rb1 [14.b4 right away could be good as Black cannot capture twice on b4 with the rook on a8 unprotected.] 14...f4 [14...Bh6 is a worthy alternative as Black seeks to get the bishop outside with pawn chain with ...Be3+] 15.b4 axb4 16.axb4 g5 17.Bf2 Nf6 18.h3?! [18.c5! g4 19.cxd6 cxd6 20.Nc4 quickly starts the play on the queenside. White would have a clear edge.] 18...b6 [18...g4 right away starts the kingside action 19.hxg4 hxg4 20.fxg4 Qg6 is at least equal for Black.] 19.c5 Kristian breaks through at the cost of a pawn. It is a worthy sacrifice and takes Black's focus off of the kingside. The psychological impact is also important as chessappeals begins to think too defensively. [Interesting is 19.Ra1 as 19...Bd7?! 20.c5! Nxb4 21.Rxa8 Qxa8 22.c6 Bc8 23.Qb3 will win a piece] 19...bxc5 20.bxc5 Nxc5 21.Bxc5 dxc5 22.Nb5 Qe7 23.Nc4 Ba6?! now the battle is only on the queenside where White has the edge. Black could keep equality by continuing with the plan - [23...g4! 24.d6 cxd6] 24.d6! cxd6 25.Nbxd6 The extra black c-pawn is not important for now. What is important is that White has a strong queenside initiative and Black has been held up on the kingside. It is much easier to play the white position as he has the tactical possibilities. 25...Rfd8
26.Nf5! Qe6 [26...Rxd1 27.Nxe7+ Kf7 28.Rfxd1 Kxe7] 27.Qc2 A marvelous positon for White. The knight on f5 is very powerful and the light squares in the black camp are weak. 27...Rab8 28.Rfd1 Qc8?? a blunder under pressure [28...Rxd1+ 29.Rxd1 Bf8 30.Ra1 leaves Black suffering but keeps everything together for now] 29.Ne7+ kclemens won by resignation 1-0
