2723 2013 · White wins (resignation, time or agreement)
Nepomniachtchi (2723) against Cheparinov (2678), 2013: a Philidor Defence that turns into a test of patience. Queens come off early with 16...Qxg4, and White stacks rooks on the h-file for a long bishop-versus-bishop grind, dozens of moves of pure manoeuvring. The turning point comes very late: 95...Rh6+ is a missed chance that swings the evaluation from +1.4 to +3.5 for White. Accuracy tells the story — 90% for White, 82% for Black — a gap that widens over time rather than in one blow. The lesson: in endings this long, one badly chosen rook square can turn an unpleasant position into a lost one.
