Peter Leko vs Veselin Topalov · 2005 · move 18.
Which knight move attacks White’s queen on e2?
The opening round of the 2005 world championship produces a sharp Sicilian and then an unusual ending: White has two knights while Black has two bishops. Topalov’s central break starts the counterplay, and his bishops later find active diagonals. The final pawn move attacks a centralized knight and shows why piece activity must be reassessed after each exchange.
