Illescas Cordoba-Banikas, Istanbul 2012, saw the Parma Variation, and a critical gambit line: 1 d4 Nf6 2 c4 e6 3 Nc3 Bb4 4 e3 0-0 5 Bd3 d5 6 Nf3 c5 7 0-0 dxc4 8 Bxc4 Nbd7 9 a3 cxd4 10 axb4 dxc3 11 bxc3 Qc7 12 Be2!?
This pawn sacrifice came to prominence when Kramnik played it against Kasparov in their 2000 World Championship match. White gains considerable compensation in view of his active pieces and bishop pair. The modern preference after 12...Qxc3 appears to be 13 Rb1!?, as chosen by Illescas, instead of Kramnik's 13 Ba3.
