- 42. Rxf7+ — the rook takes the pawn on f7 and uncovers a check from the bishop on b6 and at the same time attacks the rook on g7.
- 42… Ke8 is forced: it is the best way out of check.
- 43. Rxg7 — the rook takes the rook on g7.
Why it works. Moving one piece uncovers an attack from another, creating two threats in a single move. At the end of the line White is about 6 points of material better off.
