The game between the two top seeds was quite difficult – even to name the opening is not an easy task. We’ll just call it a Nimzo/Queen’s Indian hybrid. Anyway, Black’s play was very thematical and when she had managed to push d6-d5, Polgar was doing fine. Ivanchuk subsequently played quite risky and indeed was losing at one point. 46…Qd4 wins on the spot and Polgar did see it, but not the exact pointe – see the game viewer.
Ivanchuk, V (2756) – Polgar, Judit (2687) [E21]
