Volokitin, And – Cheparinov, I.

2638 2014 · Black wins (resignation, time or agreement)

Volokitin (2638) versus Cheparinov (2682), 2014: a classical King’s Indian, Black pushing 10...f5 and 12...g5 while White works the other wing with 14.c5 and 17.a5. Accuracy stayed high — 88% of White’s moves at least good, 90% of Black’s — yet the advantage kept switching hands. With 26.Nxd6 White let a chance slip, the evaluation moving from +0.1 to +2.2. Black returned the favour with 28...Bh3, which took it from -2.2 back to 0.0. Later 40...e3 (from +0.4 to +1.9) and 41.Re1 (from -1.9 to -0.1) cancelled each other out too, and Black converted the rook-and-bishop ending. The takeaway: in these sharp structures, a won position lasts exactly one move.
