Predke, A. – Ibarra Jerez, JC.

2688 2022 · White wins (resignation, time or agreement)

Philidor Defence, 2022: Predke (2688) against Ibarra Jerez (2570). Black handles the opening well until 12.Bxe5, flagged as a mistake, swings the evaluation from −0.9 to +0.9 — White, instead of defending, suddenly sits on the right side of the assessment. Black’s chance comes later: 31...Rc8 is a missed opportunity that moves the needle from −3.5 to −0.2, a large advantage handed back in one move. From there the game drifts, 37...Re2 (from +1.3 to +3.5) confirming the trend, and White converts, 1-0. Accuracy: 89% for White, 83% for Black. The takeaway: a winning position survives exactly as long as your care does.
