Going into the third round of the Batavia Chess Tournament 80% of the games had been decisive so far. In order to maintain this percentage 4 games today would have to be decisive. The tournament features only one player who is on a 100% (2/2) score so far; Dimitri Reinderman. We will start by taking a look at his game and see if he can maintain his perfect score.
Bosboom,Manuel (2410) – Reinderman,Dimitri (2582)
1.c4 g6 2.Nf3 Bg7 3.Nc3 c5 4.h4 From an early stage of the game Bosboom is showing that he is not afraid to challenge the tournament leader and is immediately aiming at an attack on the black kingside. The strategy of pushing the h-pawn early is recently back into fashion after being popularised by AlphaZero and can be seen in many top games.
4…Nf6 5.a3 Bosboom is taking some liberties in the opening. By pushing both his a and h pawns he is neglecting his development for the time being.
5…Nc6 6.b4?! cxb4 6…d5 Would be a thematic in order to open the position as much as possible since white has so far neglected some development
7.axb4 Nxb4 However, nothing is wrong with the pawn-grab
8.Qb3 Nc6 9.Bb2 0–0 10.e3 d6 Black has achieved a better position out of the opening. His king is safer, he is ahead in development and is a pawn up. In the meantime, it is hard to imagine where the white king will find shelter in the future with pawns having moved on both wings.
11.h5? One should credit Bosboom for his ultra-aggressive approach against the tournament leader in which he seems fearless. However, with more objectivity this move seems premature in the current position. Black already has a better position and white is intending to further sacrifice material for the initiative. Although different moves might be stronger Bosboom is consistent in his attacking and enterprising play/
11.Be2 A normal development move seems more logical. Yet the question remains where to put the white king. In case of putting it on the kingside one may wonder if the h4 push was worth a tempo in the opening.
11…Nxh5 Correctly not being afraid of the exchange sacrifice
12.Rxh5? gxh5 13.Be2 e5 14.Nd5 b6 15.g3 Ne7 Challenging the strong knight on d5 and due to the material advantage every exchange will bring black closer to a win.
16.d4 Trying to add some fuel to the flames, as not much was achieved so far by the sacrifice of material
16…e4–+ 16…Nxd5 17.cxd5 e4 18.Nd2 h4 19.Nxe4 Bf5 20.Nd2 hxg3 21.fxg3 Re8–+
17.Nh4 Nxd5 18.cxd5 Bf6 19.Ng2 Bg4 20.Bb5 h4 21.gxh4 Bf3 The white king turns out to be less safe than his black counterpart.
22.Nf4 Bxh4 23.Kd2 23.Bc6 Bxf2+ Is the main threat. White cannot capture on account of a mating attack. 24.Kd2 (24.Kxf2 Qh4+ 25.Kf1 Kh8 Getting ready to use the last piece for the attack 26.Qc2 Rg8 Mate follows as a result of Qh1–Qh2–Rg1. See diagram 1)
23…Bxf2 24.Ba3 Qf6 25.Rf1 Bh4 26.Bc6 Rad8 27.Ne6 Desperately trying to confuse matters
27…fxe6 28.dxe6 Kh8 29.Bxe4 Qg7 30.Rxf3 Qg2+ 31.Kd3 Rxf3 32.Bxf3 Qxf3 Black calmly defended and is now a rook up
33.d5 Bf6 34.Kd2 Qf2+ 35.Kd1 Rg8 With mate following very soon. Reinderman maintained his perfect 100% score with a smooth black win.
The great score with black so far remains. Let us take a look at one of the few examples so far in which white managed to strike back.
Zwirs,Nico (2443) – Sukandar,Irine Kharisma (2408)
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.c4 Nf6 6.Nc3 d6 So far the round 1 game of Nijboer-Sukandar was followed
7.f3 The first deviation from the round 1 game
7…Nxd4 8.Qxd4 Bg7 9.Be3 0–0 10.Qd2 Be6 11.Rc1 Qa5 12.b3 Rfc8 13.Be2 Rab8 Following a pet line of Zvjaginsev
13…a6 14.Na4 Qxd2+ 15.Kxd2 Nd7 16.g4 f5 Is how Guseinov approaches this line
14.Nd5 Qxd2+ 15.Kxd2 Nxd5 16.cxd5 Bd7 17.Bxa7 Rxc1 18.Rxc1 Ra8 19.Be3N The first new move and what seems to be the strongest move in the position
19.Rc7 Was previously played
19…Rxa2+ 20.Kd1 Ra1 21.g4 f5?! This creates an unfavourable pawn transition for black in which white will soon have an outside majority on the kingside. Resulting in a potential outside passed pawn in a later stage of the endgame.
21…Rxc1+ 22.Bxc1 h5
22.Rxa1 Bxa1 23.exf5 gxf5 24.g5 Kf7?! This unfortunate square no longer allows black to stop white from achieving h4–h5 with the ability to create a passed pawn.
24…Bc3 Allows black to stop white from getting his pawn to h5. The idea of this move is that if white plays Kc2 black can respond with Be1 stopping the h-pawn by controlling h4 25.h4 Be8 26.f4 Bf7 27.Bf3 h5 Black manages to stop the white play on the kingside
25.h4 e5 26.dxe6+ Bxe6 27.Kc2 Bd5 28.h5 Be5 29.f4 Here black missed the last chance to somewhat maintain the balance
29…Bh8 29…Be4+! Not allowing an exchange of the light squared bishops without getting connected passed pawns which would stop the white king from winning the game in case all bishops are exchanged. 30.Bd3 Bh8±
30.Bc4 Now white manage to exchange this bishops after which he will use his dark squared bishop to challenge his black counterpart. The remaining endgame will result in a win as the constant thread of creating a passed pawn limits the black king in his movements while the white king can go escort his pawns to becoming a new queen.
30…Ke6 31.Kd3 b5 32.Bxd5+ Kxd5 33.Bd2 Bb2 34.Bc3 Bc1 35.g6 hxg6 36.h6 Nico Zwirs won a nice technical game as the pawn is unstoppable
Trent,Lawrence (2386) – Nijboer,Friso (2469)
1.d4 Nf6 2.Nc3 d5 3.Bf4 Just like in round 1 Trent took another chapter from the Jobava book and aimed for a creative position from the opening.
3…Bf5 4.f3 e6 5.g4 Bg6 6.h4 h6 7.e3 Nc6 A rare move, but one that has no direct refutation. It may have been played by Nijboer in order to get his opponent out of book.
8.Bd3 Bxd3 9.Qxd3 Bd6 10.Nge2 Qe7 11.0–0–0 0–0–0 12.Kb1 Kb8 13.Bxd6 Qxd6 14.Na4 e5 15.Nec3 exd4 16.exd4 Nb4 17.Qd2= So far the balance was held by both players.
17…Na6 18.Nb5 Qb4 19.Qxb4 Nxb4 20.c3 Nc6 21.Nc5 b6 22.Nd3 Rde8 23.Nf4 Nd8 24.g5 Nd7 25.Na3 c6 26.Rhe1 Rxe1 27.Rxe1 hxg5 28.hxg5 Kc7 28…g6 Black can aim for a position with a pawn more or for a position in which his pieces are more dominant than the white counterparts. 29.Nc2 Rh4 30.Nd3 Ne6 31.f4 (31.Rg1 Rh3 32.Nce1 c5 Black stands better as a result of his better coordinated pieces) 31…Nxf4 32.Ncb4 Nxd3 (32…Kc7 33.Re7 Nxd3 34.Nxd3 and white wins back the f7 pawn due to the threat of Ne5) 33.Nxd3 Re4 34.Rf1 Re7³ White is more actively, but black is a pawn up (which is blockaded well)
29.g6 Rh4 29…Rf8 30.Re3 a6 31.gxf7 Rxf7 32.Nd3 Kd6³
30.Nd3 Rh3 31.Kc2 fxg6 31…Rg3 Was again a chance for an advantage 32.gxf7 Rxf3 33.c4 dxc4 34.Nxc4 Rxf7
32.Re7 Kd6 33.Rxg7 Ne6 34.Rxg6 Rxf3 35.Nb1 Rf6 36.Rxf6 and the balance was held
Warakomski,Tomasz (2501) – Feuerstack,Aljoscha (2459)
1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Qe2 Qe7 6.d3 Nf6 7.Bg5 Nbd7 8.c4 h6 9.Bd2 Nc5 10.Qxe7+ Bxe7 11.b4 Na4 12.Nc3 Nxc3 13.Bxc3 0–0 14.0–0–0 Re8 Black seems to be more comfortable out of the opening as the white pawns on the queenside might be overexposed in the future.
15.Re1 Bd7 16.Be2 d5 17.Nd2 d4 17…Bf5 It was possible to maintain some more pressure 18.Bf3 Rad8
18.Bxd4 Bxb4 19.Bf3 Red8 20.Re3 Ng4 21.Bxg4 Bxg4 22.Nb3 Bf5 22…a5 Winning more space on the kingside and potentially limiting the white king his breathing space in the future
23.Kc2 b5 24.cxb5 c6!? White defended well
24…a6! 25.bxa6 (25.Kb2 Rd5 26.Rc1 Bd6 27.bxa6 Rxa6 28.Bc5 Bf4 29.Re8+ Kh7 30.Be3 Bd6 31.Bc5 Rxd3 32.Bxd6 cxd6) 25…Rxa6 26.Kb1 Be6 27.Bb2 Rda8 28.Nc1 Bd5 29.f3 f6 The black bishops are dominating
25.bxc6 Rac8 26.Kb2 Rxc6 27.Rc1 Rxc1 28.Kxc1 a5 29.Bc5 Rc8 30.d4 a4 31.Kb2 axb3 31…Rb8 32.Kc1 Bxc5 33.Nxc5 Rb1+ 34.Kd2 Rb2+ 35.Kc3 Rxf2
32.Bxb4 bxa2 33.Kxa2 Rc2+ 34.Ka3 Rxf2 35.Rf3 Rxf3+ 36.gxf3= Bh3 37.f4 f6 38.Kb3 Be6+ 39.Kc3 Kf7 40.Kd3 f5 41.Ke3 Bd5 42.Bd6 g6 draw was agreed
Admiraal,Miguoel (2501) – Van Haastert,Edwin (2438)
1.c4 e5 2.Nc3 Nf6 3.Nf3 Nc6 4.e4 Bb4 5.d3 d6 6.a3 Bxc3+ 7.bxc3 0–0 8.g3 Ne8 9.Nh4 Ne7 10.Bg2 c6 11.0–0 f5 12.exf5 Nxf5 13.Nxf5 13.Nf3 it was possible to keep on the knights in order for white to create more pressure on the black pawn on e5 13…Nf6 14.c5 e4 15.dxe4 Nxe4 16.cxd6 Nfxd6 17.Re1 Qf6 18.Bf4
13…Bxf5 14.f4 Qd7 15.Ra2 Nf6 16.fxe5 dxe5 17.Bg5 h6 18.Bxf6 Rxf6 19.d4 Bg4 20.Qd3 Rxf1+ 21.Bxf1 Re8 22.Rf2 e4 23.Qe3 Bf3 24.c5 b6 25.cxb6 axb6 26.Rb2 Qa7 27.c4 c5 28.d5 Qc7 29.Rd2 Qd6 30.Bh3?! 30.Bg2 Aiming for the exchange right away
30…Kh8 31.Rf2 Qe5 32.Bg2 32.d6 The only move to maintain the balance according to the silicon machine. The d-pawn keeps the black pieces busy enough that they don’t establish the right pressure on the white setup.
32…Bxg2 33.Kxg2 Qd4 34.Qe2 b5!! Aiming for a winning transposition to the endgame
35.cxb5 Qxd5? 35…e3!–+ 36.Rf3 (36.Rf1 Qxd5+ 37.Kg1 c4 38.a4 Qd2 39.Re1 c3–+) 36…Qxd5 37.b6 c4 The black passed pawns are decisive
36.Qe3 c4 37.a4? This move allows black to win the a-pawn
37.b6! c3 38.Rc2 Rc8 39.a4=
37…c3 37…Qd3! 38.Re2 Qd1 Threatening both c3 and Qxa4
38.Rc2 Rc8 39.b6 Qb3 40.Qxe4 Qxb6 41.h4 Qa6 42.h5 Rf8 43.Rf2 Rxf2+ 44.Kxf2 Qc8 45.Qc2 Qc5+ 46.Ke2 Qxh5+ 47.Kd3 Qf3+ 48.Kc4 Qxg3 49.Qxc3 Qg4+ 50.Kb5= Qd7+ 51.Qc6 Qd3+ Although black is a pawn up he is not winning in this position due to the advancement of the white pawn. Black cannot exchange queens as otherwise the white pawn promotes first.
52.Kb6 Qd4+ 53.Kb7 Qb4+ 54.Qb5 Qe4+ 55.Qc6 Qb4+ 56.Qb5 Qe4+
Reinderman is currently one point ahead of Van Haastert after three rounds. Let us hope that the fighting spirit of the participants remains as it has been so far, resulting in many decisive games with very enterprising chess.
