🔸Alekseev,Evgeny (2659)
🔸Ivanchuk,Vassily (2768)
🔸FIDE World Cup Khanty-Mansiysk 2011

17...Rc7!
Here lies the logic behind Ivanchuk mysterious rook move. Black prepares his desired set-up without allowing his knight to be pinned against a rook or queen on d8.
17...c5 This advance opens long diagonal for the white bishop on g2.
17...Qb6? would lose a pawn after 18.Bxh6 Bxh6 19.Qxf6.

🔸Epishin,Vladimir (2630)
🔸Ivanchuk,Vassily (2720)
🔸Interpolis Tilburg 1992

23...Rc7!
Ivanchuk with defending the a7-pawn releases his queen. Superb defending and prophylaxis by him, making it extremely tough for Epishin to find a way through, who soon loses focus slightly.
23...Bf5 24.Bxf5 Nxf5 25.gxf5 Rxf6 26.Ne5 White is clearly better.
23...fxg5? 24.Ne5 black cannot defend all of his weaknesses.

15...Qa6!
White has problems defending the b3- and d3-squares. Castling becomes a remote dream.
15...d4?! Allowing the opponent's king to castle: 16.exd4 Qf5 17.0-0
15...Qf5? 16.0-0 This leaves Black with a weak isolated pawn at d5.
