The game between Nahun Gavarrete, of Honduras, and Guyana’s Taffin Khan at the International Chess Federation’s 2020 Online Chess Olympiad last month sizzled with known theory until Khan committed a horrendous blunder and resigned in frustration.
Khan played white against a King’s Indian Defence, and he and his opponent treaded carefully until the dreaded doomsday moment arrived. Perhaps Khan was experiencing time trouble which manifestly engineered his defeat. He left a pawn en prise (exposed to capture) and was forced to sacrifice a Rook for a queened passed pawn. The Olympiad games had a 20-minute per player feature.
