Ivanchuk - Tiviakov Benidorm (rapid) 2008 White to move
1.cxb5! Rxc3 2.bxa6!!
3...Bd7 4.a7 R3c5 was preferable, although after 4.b4 Qxa7 5.bxc5 dxc5 6.Qf2 White's advantage is practically decisive – Golubev.
This helps White to create a strong passed pawn on the a-file. The prophylactic 1...Rec8 was better.
Simple but strong. Now that 3...Rec8 fails tactically, White wins the battle for the c-file.
