The longest game of Round 8 of Grand Prix Beijing was played by "veterans": Boris Gelfand and Vassily Ivanchuk. Ukrainian GM faced a lot of problems during the game, however, he still could hold in the endgame.

GELFAND - IVANCHUK

65...Kh3 It seems like a mistake as the black king cuts itself from the game; but actually it only seems to be wrong move.

The main question is what will happen in case of 65...Kxh4. It turns out nothing is clear: 66.Nxd6 Rxd6 67.Rh1+ Kg5 68.Rxh7 Ra6 69.Re7 Kf6 70.Rxb7 (70.Re8 isn't any better 70...Rxa5 71.Re6+ Kf7 72.Rxe5 Ra6 and Black should hold) Rxa5 71.Rb5 Ra3+ 72.Kd2 Ra2+ 73.Kc3 Ra3+ 74.Kb2 Re3 75.Rxc5 Rxe4 76.Rc6+ Kf5

77.c5 (definitely doesn't win 77.d6 Rd4 78.Kc3 g5 79.c5 g4 80.Rc8 Ke6) g5 78.Rh6 Rc4 79.c6 g4 80.Kb3 Rc5 81.d6 Rxc6 82.d7 Rxh6 83.d8Q

Can White win this position? Yes, it can but only with the help of Black. If Ivanchuk has played correctly the position would most probably be drawn.

Let's remember this variant, we will need it in two moves.

66.Rg1 Nf8 67.Ke3

67...Kh2? Now it's really a mistake. The variant we have mentioned gave Black a chance to escape 67...Kxh4!. In comparison to that variant white king is on e3 instead of d3, however, that changes nothing: 68.Rf1 Nh7 69.Nxd6 Rxd6 70.Rh1+ Kg5 71.Rxh7 Ra6 72.Re7 Kf6 73.Rxb7 Rxa5 74.Rb5 Ra3+ and so on.

White can try another continuation: 68.Rh1+ Kg5 69.Rh8 Nh7. Here 70.Nxd6 brings to already familiar position: 70...Rxd6 71.Rxh7 Ra6 72.Re7 Kf6 73.Rxb7 Rxa5 and so on.. This shouldn't be successful as well: 70.Re8 Nf6 71.Re6 Ng4+ 72.Ke2 Rh7 73.Nxd6 Kf4! 74.Rxg6 Rh2+ 75.Kd3 Nf2+ 76.Kc3 Nxe4+.

Obviously that's about the objective evaluation, because in practical sense it's absolutely not easy for Black to find all the best and accurate continuations move after move.

68.Rf1 Nh7 69.Rf3! That's the end.
69...Kg2 70.Nc3 g5 71.hxg5 Nxg5 72.Rf5
Ivanchuk decided to stop defending and he was quite right here: the cut off king, the difference between the activity of his and the rival's pieces, d6-pawn as a weakness - all that creates a considerable and even decisive advantage for White. 1-0
