@lichess Qh6. The g pawn can’t capture because it’s pinned. If black answers Bf8, then Rxg7+ Kh8 Qxh7#; otherwise Qxg7#.

@lichess Can't I just take on f6? I guess I'm missing something obvious.

@lichess 1. Rxg7! King can't take, because of 1. ... Kxg7 2. Bh6+ Kg8 or Kh8 3. Qf6 and mate next move.

@Pentaxke

And what if 3. ... Bf8? 🤔

Pentaxke, 7 months ago

@lichess Ok, you postponed mate with one move.

1. Rxg7! Kxg7 2. Bh6+ Kg8 3. Qf6 Bf8 4. Qg5 Bg7 5. Qxg7#

So still 1. Rxg7! and Black King can't take and loses also the knight on f6.

@Pentaxke
Black can cover with 4. ... Ng6!
Something needs to be changed before. 🙂

@lichess @Pentaxke 3. Rxe5 is probably just good enough.
