Ruy Lopez Anastasia Mate in Chess

The ruy lopez anastasia mate is a tactical mate pattern from the Ruy Lopez where Black’s rook reaches the 7th rank and White’s king gets trapped by a pinned piece. A defining feature is the “Anastasia” setup: White’s knight on c3 (or a closely related square) is pinned to the king, so it can’t capture the checking rook. When the rook on e7/e1 (depending on the exact line) gives the decisive check, the king has no safe squares and the mate is forced.
