After 19.Nxg7! black probably planned 19...Rxe3 but forgot 20.Rxe8! with the threat Nxf6+!

Taking in f5 is very dangerous because of Qh4 with a strong attack for black. But 1.Qc4+ and 2.Qxg4 is simply winning!

After 2...Rxe5 3.Qxa7 if black plays 3...bxc4 4.Qb8+ wins the rook in e5! So black has to win to pawn back with 3...Rg5 and the game is approximately equal. If 2...Qe8 3.Qxa7 bxc4 4.Nxc4 there is no Rd1+ any more and white is in the game.

After the forced line 1.Rxd7 Rxd3 2.Qxg4 Rxc3 Sokolov totally forgot white has 3.Qb4! winning on the spot.

1...c5+ (the game went 1...Rxe5?? 2.Rxf7?? (2.Re3 1-0) c5+ 0-1) 2.Ke4 Ra4 3.Rc3 Ra5 and black pressure on e5, c4 and a3 is enough to draw, for example 4.Rb3 Ra4 and if white try Rb6+ and Kd5/Kf5 black will take in a3 and h3, drawing the endgame despite being a pawn down.

1.Qg5+ Kh8 (Kf8 Qh6+ Kg8 Rg3+ Kh8 Qg7#) 2.Rg3 Rg8 3.Qf6+ Rg7 4.Qxg7#

1...Qe4! 2.Bf2 (if 2.Bg1? Qg2+ winning the bishop with check; if 2.Be3 Qd3+ ; if 2.K moves the black K advances with a quick mate; if Bd8/c7/a5 Qe5+) Qd3+! (the difficult move) 3.Ke1 (Kc1 Kb3 mating) Qf3 (threatening Kd3) 4.Kf1 Kd3 5.Kg1 Ke2 with Qg4+ and Kf3 to come.

1...Qxh2+ 2.Kxh2 Rh4+ 3.Kg1 (Kg3 Nf5#) Ne2++ 4.Kf1 Ng3#

56.c6! Bxc6 57.Rf6 Bb5 58.Nc5 Rxh3 59.Nxa6 +-
Bacrot had the idea but he tried one move too late.

1...g5+ 2.Kxh5 Qxg4+! 3.Qxg4 Bf7#

1...Ra4! clever move! (Cornette played 1...Ra3 but after 2.Rxg6 Rxe3 3.f5 black are suffering and lost 4 moves later ; 1...g5 is interesting but not a safe draw) 2.Kg2 (if Rxg6 Bxf4 exf4 Rxf4 with an immediate draw) Bxf4 3.exf4 Rxf4 4.Be6 Rxg4+ with a draw.

1...Ra7 (only move, Tkachiev played 1...c5?? and was lost after 2.Ra3 +-) 2.Ra3 Ra5! it's very important to block the pawn as soon as possible. Now it must be draw: black will go to e6 with the king and then play c5.

Because 19.Qd5! black still have some compensations but can't play 19...Rxe2 20.Qxd7 Qxf4 because of the unpleasant surprise 21.Qxb7 with a fork!

Contact me if you would like answers.

1...h5! threatening mate in 1 and stopping all back rank problems, is a nice intermediate move, 2.gxh5 Nc3 3.Rd2 Rxd4! 4.Qxd4 Qxd4 5.Rxd4 Ne2+
