Spoelman, W. – Plat, V.

2578 2018 · White wins (resignation, time or agreement)

Old Indian Defense, 2018: Spoelman (2578) against Plat (2569), a closed game where both sides manoeuvre behind their pawns for a long time before everything tips. The engine credits White with 77 % at-least-good moves and Black with 85 % — yet it is Black who cracks. The clear turning point comes on move 27: 27...Kg8 shifts the evaluation from 0.0 to +1.7, turning a holdable position into a White advantage. Black then lets it slide further: 29...Qc5 runs from +1.4 to +5.3, and 33...Kf8 from +7.1 to +15.0. The lesson: a high accuracy figure is no protection against one badly chosen move at the critical moment. White converts, 1-0.
