I’m referring to puzzle https://www.chess.com/puzzles/problem/2702988

… and specifically its last move. As shown in the below screenshot, computer at level 30 thinks capturing the black knight with white’s rook is a superior move compared to the next best move, Kh2.

However, chess.com only accepts the king move as the correct move. How’s so?

I have long held that chess.com policy to unnecessarily prolong puzzles, in order to punish those who get the first move wrong, is ridiculous. However, this puzzle takes the cake!
