Mate in 2 Puzzles!
In 43 1.Qc6 with an unstopable threat of Rxe8# also mates in two.
In 47 1.Qc8 also mates in three, and all the main lines starting with Qc8 have duals.
In 48 there is a mate in one (1.Qe6#).

That's a dual (wich is qiute unfortunate because it's a really nice concept) because after Bd4 right away black has to play h6(only legal move) allowing Qxh6#
fixed it!
That is what this forum is for! Most of chess.coms attention goes to game play and game players. Most of their puzzles are also from games. But they have given us this forum to place puzzles for "puzzles sake" and not just under the pretense it is "training for games". Even though it is actually good training!
