30... Qd7!
With the idea of f5-e4-Be5-Bd4.
31. Bd3 g6 32. g4
White has prevented the opponent's plan, but now, his kingside becomes a target for attack.

Anand's carelessness. He has missed a beautiful tactical blow from his opponent.

Setting up a trap in a drawish queen ending.

Mamedyarov should have played 50...Qe2 or 50...Kg7 to prevent his opponent from playing 51.h5!.

White has a lead in development and makes use of it to mount an energetic operation in the center.
19.Rd5!
Rubinstein presents Black with a difficult choice between playing down his main line and 19...Rc4. Neither equalizes.
19...Rxd5 20.exd5 Nd4+?
20...Ne7 was better.
21.Kd3 Ke7 22.f4!
White isolates and seriously weakens Black's e-pawn. White's king will be able to attack it, while at the same time giving extra support to his potentially dangerous passed d-pawn from the excellent blockading square e4.
22...f6 23.fxe5 fxe5 24.Ke4
An even better move would be 24.Ne4+/-

25...e5!
This stunningly simple move opens the game for Black's rooks and king to swarm all over key space in the kingside and center. White's rooks lack space and White's king is too far from the center and kingside to do much about it.
26.dxe5
Could it be that Schlechter had now intended to play 26.Rg5, but then saw Igor Zaitsev's (presumably also Rubinstein's) wonderful refutation? Zaitsev gives 26...Rf6! 27.Rxf6 Kxf6. Black also wins the king and pawn endgame, due to his powerful king and 3-2 kingside pawn majority, after 28.Rxe5 Rxe5 29.dxe5+ Kxe5, and if 30.Kc2 Ke4 31.c4 g5 32.Kc3 f5 33.b4 h4 34.a4 g4 35.a5 f4 -+.
