Anastasia's Mate

Anastasia's Mate is a typical checkmating pattern that occurs in games. The key things to note are:

1. A White Knight on e7 (or Black Knight on e2 if transposed).
2. A Black pawn on g7.
3. A Black King on h8.

Since the Knight covers the g8 and g6 squares, usually a sacrifice on h7 occurs then the Rook or Queen deliver mate.

Here Qxh7 followed by Rh3 wins.

Another example:

A mate in 3 starting with Ne2+.

Recognizing the pattern, we can solve this puzzle from lichess. It's a little bit tricky since move 2 is a quiet move. 😀
