Tbilisi Rd7: Crucial Mistakes

by Alejandro Ramirez
2/22/2015 – Decisive mistakes in Tbilisi! Grischuk missed an unusual tactic from Mamedyarov, leaving him in a position down two pawns for very little instead of having great compensation for only one. Dominguez blundered in the dreaded move 39 while Giri was unable to hold an endgame that required precision against Jakovenko, who is now only half a point away from Tomashevsky.

Kasimdzhanov, Rustam ½-½ Radjabov, Teimour
Kasimdzhanov again tried his 5.Bd2 Grunfeld, but this time it was much less successful than it was against Svidler. Radjabov was able to liquidate the central tension and started trading pieces and pawns. The board was barren by move 28, when the players agreed to a draw in a 3v3 rook endgame.

Kasimdzhanov seems to be adopting this 5.Bd2 line as his pet variation against the Grunfeld

Radjabov was his usual solid self with black

Andreikin, Dmitry ½-½ Vachier-Lagrave, Maxime
The real drama in this game occurred when both players were already low on time, and both were fighting too and nail for their initiative!

Every Russian schoolboy knows that in opposite colored bishop positions, king safety is key!

Tomashevsky, Evgeny ½-½ Svidler, Peter
Svidler showed again that even when Black is down a pawn in many Grunfeld variations, he retains an initiative and strong compensation for the material deficit. He was able to regain his pawn and threaten White's center, so Tomashevsky pulled the brakes and forced a perpetual.

Jobava, Baadur 1-0 Dominguez, Leinier
The Georgian star used his patented Jobava Variation (it sounds way cooler than "reversed Philidor Defense"), which for one reason or another has brought him considerable success. Dominguez was holding his own until time pressure cost him half a point:

38...Rxc5 39.Ra4 A complicated position. White has a powerful passed pawn on the a-file, but at the same time he has to be careful since his knight on c4 is pinned and the a-pawn might fall. Nc7? Time trouble costs the Cuban player half a point, at least. 39...Nd6 40.Qb3 40.Rxd6 Looks somewhat dangerous at first, but a quick calculation reveals that White has no way of pushing his pawn past a7, where it will perish. Qxd6 41.Nxd6 Rxc2 42.a7 42.Nc4 Rxa6 42...Rd2 43.Nc4 Rd7 40...Nxc4 41.a7 Rb5 42.Qxc4 Qxc4 43.Rxc4 Rxa7 44.Rxc6 with a dead draw. 40.a7 Nb5 41.Qd3 Rxa7 42.Rxa7 Rxc4 42...Nxa7 must have been Dominguez's original intention, but it does not work: 43.Qd8+ Kh7 44.Ne3 and Black is too uncoordinated. The main threat is Qf8 followed by Nf5 or Rd8, wich a mating attack. 43.Qd8+ Kh7 44.Re7 Qf6 45.Qd7 If black could hold his f7 pawn he might have a chance of holding the position, but it is not possible and the rest is trivial for Jobava. Rd4 45...Rc2 46.Qf5+ Qxf5 47.exf5 still leaves the f7 pawn hanging. 46.Rxd4 Nxd4 47.Rxf7 Qg6 48.f3 c5 49.h4 h5 50.Kh3 Qh6 51.g4 hxg4+ 52.Qxg4 Kg8 53.Rc7 Ne6 54.Rc8+ Kf7 55.Qf5+ Ke7 56.Qxe5 Kd7 57.Ra8 Nf4+ 58.Kg4 Qxh4+ 59.Kxh4 Ng6+ 60.Kg3 Nxe5 61.Kf4 Kd6 62.Rd8+ Nd7 63.Rg8 c4 64.Rxg7 Ne5 65.Ke3 c3 66.f4 1–0

Jobava,B2696Dominguez Perez,L27261–02015C44Tbilisi FIDE Grand Prix7

Dominguez was unable to cope with the dreaded Jobava variation

Jakovenko, Dmitry 1-0 Giri, Anish
A Dutch! Black's weaknesses on the kingside were compensated by weakness on the queenside from his opponent. The endgame they entered gave chances to both sides, but Jakovenko always seemed to be just a tad better. When it was time for Giri to find the drawing line, he was unable to do so.

Giri, metaphorically, cut his own string today

Jakovenko,D2733Giri,A27971–02015A88Tbilisi FIDE Grand Prix7

Jakovenko's second victory on this tournament puts him at only half a point from Tomashevsky

Grischuk, Alexander 0-1 Mamedyarov, Shakhriyar
Grischuk was playing a great game and had fantastic compensation for his pawn when he missed an important resource from his opponent!

Shakhriyar Mamedyarov, the new Joseph Blackburne, who was nicknamed
"the Black Death" due to his prowess with those pieces?

The development advantage and central control gives White plenty of compensation. Qxa2 11.Be2 Qa5 12.0-0! What a nice move! The knight on d2 is hanging, but White will be able to recover it without problems and keep his compensation. Bxd2 13.Ra1 Qb4 14.Qc2 c5 14...Bxe3 15.fxe3 opens up the f-file, which is very dangerous for Black. 15.Ra4 Qb6 16.Qxd2 The minor piece is recovered and Black's development is sub-par. He is up a pawn, but clearly on the defensive side. e5 17.Ra5? Overlooking or underestimating Black's next move! Qh6 An unusual tactic. The bishop is hanging on h4, but also important is that the e-pawn is now pinned. 18.Bg3 exd4 19.Bf4 19.f3 was probably the only way to fight for compensation, but it should be insufficient. 19...g5 20.Bg3 d3 21.Bd1 White is not dead, for his two missing pawns he has the pair of bishops and Black's king will always feel uncomfortable, but Black should win with good play. Mamedyarov made his life pretty hard at different junctures, but the win was never in question. b6 22.Ra1 f5 23.Ba4 0-0 24.f3 Qe6 25.fxe4 fxe4 26.Bxd7 Rxf1+ 27.Rxf1 Bxd7 28.Qc3 Qe7 29.b3 Re8 30.Qa1 a5 31.Be1 Rd8 32.Rf2 h6 33.Bd2 Rf8 34.Rxf8+ Qxf8 35.Qe5 Qe8 36.Qf6 Qe6 37.Qd8+ Kf7 38.Bc3 Qd6 39.Bd2 Qe6 40.Bc3 a4 41.bxa4 Bxa4 42.Qc7+ Ke8 43.Bd2 Bd7 44.h3 Ke7 45.Qb8 h5 46.Qh8 Qxc4 47.Qe5+ Qe6 48.Qxg5+ Kd6 49.Qxh5 b5 50.Qh8 b4 51.h4 Qa2 52.Qf6+ Kc7 53.Qf2 b3 54.Bc3 Qxf2+ 55.Kxf2 Kc6 56.Ke1 Kb5 57.h5 Ka4 58.Bb2 Kb4 59.Kd2 c4 60.g3 Bg4 61.h6 Bf5 62.g4 Bg6 63.Bf6 Ka3 0–1
