📘 28. Rfb1

Topalov missed a winning continuation. He should not have given his opponent an opportunity to castle:
(28. Qxg7 Rf8 29. Rad1! With the idea of Rd8+! Bxf5 30. e6! Bxe6 31. Rfe1(idea R×e6!) Qe7 32. Ne5 a5 33. Ng4 f5 34.Qg6+ Rf7 35. Rxe6+-)

📕 20...Qe8! A typical move in such positions. Black intends to transfer his queen to h5 and continue his attack with ...g7-g5 and perhaps...Rh6.
20...g5 21.Nd4! Bxg2 22.Kxg2=/+ exchang pieces to ease the defence which is a strong idea when you are under attack.
20...Kh8? It is not logical to place your king on the same diagonal as the enemy queen.
⚪️#112 (Strategy-White to Move)
🔸Kortschnoj,Viktor
🔸Arnason,Jon L (2540)
🔸Beersheba, 1987
📕 19.Rc4! A very clever way to transfer the rook to the kingside. Viktor Korchnoi is known as a creative player.
19.b4!? and then a4 were also interesting moves to get more space on the queenside.
19.Ba3? It does not have any particular plan.

16...Na4!
Black threatens ...c7-c6!, trapping White's wayward knight. if White's knight does move, then Black forks on c3.
16...c6 17.Nxd4 Na4 18.Be3 Nc3 19.Qc2 Nxb1 20.Rxb1 Although White has also obtained an exchange, his advantage has decreased.
16...g4? An aimless move that helps white strengthen his position: 17.Qc2! c6 18.Nxd4+/-
