?? 4. Qxf5 why not 4. Bxf5
Why not 4.Bxf5?
sorry, didn't see this previous post - I think this solution delivers mate 1 move earlier
why the fourth move is not Bishop X Bishop? That wins immediately
to sookenneth : Bishop x Bishop interferes with backup that Queen recieves from Rook. Allows King some other moves.
If black goes 2 ... g6. That saves the situation for black isn't it?
It doesn't really help. If 2...g6, then 3. Bxg6 h6 4. Qxh6+ Kg8 5. Qh7#. Mate in one less move than the puzzle solution.
