Ivan Sokolov ran into a well-prepared Peter Leko in Round 10 at the 75th Tata Steel Chess Tournament 2013. Leko opted for the Nimzo Indian against Nimzo expert Sokolov. At the 2012 Olympiad Leko had suffered a painful defeat at the hands of Arkadij Naiditsch in the same line that appeared on the board, and found the novelty 15…Nh5! in his preparation of the FIDE Grand Prix Tashkent in November of last year. Instead of defending a slightly worse position, Sokolov tried to punish Black’s weakening of the b1-h7 diagonal with 16.Qc2, but was struck by the killer 16…g6 17.Rxe6 Nf4! winning an exchange, as for example after 18.Bxe7 Nxe7 19.Re3 Nf5 20.Re4 Black has the crushing 20…Nxg2! 21.Kxg2 Nxd4. Once the White attack had run out of steam, Leko took over the initiative and won quickly.
