Anand, Viswanathan – Ivanchuk, Vassily

2817 2011 · Draw

A classical Ruy Lopez from 2011: Anand (2817) against Ivanchuk (2779), a game where the balance tips three times. After 20.dxe5 dxe5 and the central exchanges, Black looks to be holding the thread, but 36...Qd2 is a missed chance: the evaluation swings from -0.4 to -2.8 from White’s point of view. Anand fails to convert either — 39.Rg4 lets part of the edge slip, from +3.2 to +1.1, and 44.Qe2 is an outright mistake, from +1.7 to 0.0. The finish is a string of black queen checks, and the game is drawn. Accuracy: 84% for White, 88% for Black. The lesson: an unconverted advantage evaporates in two lukewarm moves.
