Svidler, P. – Yuffa, D.

2723 2019 · White wins (resignation, time or agreement)

Svidler (2723) against Yuffa (2566), 2019: a King’s Indian where the queens come off at 10.Qxd8, leaving a sharp rook-and-bishop endgame. Black grabs material on the queenside and the evaluation swings hard both ways: 29...Bh3 pushes it from +1.7 to +3.4 for White, but 32.Kg3 (−3.7 to −1.8), 34.b4 (−4.1 to −2.6) and 35.a6 (−2.2 to −0.3) hand back everything White had won. The decisive moment is 35...Be4, a missed chance that lifts the eval from +0.3 to +5.5, with 38...Rb4 making it worse still, from +6.2 to +8.3. Accuracy: White 88 %, Black 83 %. The lesson: in endings like this the advantage can change hands repeatedly before it finally sticks.
