A queen sacrifice too late to stop mate.
White built a promising position out of the opening, winning a pawn and reaching a clear advantage by move 16. The game turned on move 17 when White retreated the rook to d2 instead of keeping it active on d1, allowing Black counterplay. White still had winning chances on move 22, but Rfd1 walked into a forced queen sacrifice that led to immediate checkmate.
- Active piece play in the opening
- Tactical alertness to win material
- Before moving a rook, ask: is there a more active square on the same file? Avoid unnecessary retreats when pieces are well-placed.
- When you have a winning position, scan for your opponent's forcing moves first — checks, captures, and threats — before committing to an 'obvious' move.
