puzzle 50905

chekmate in 4 moves ph4 and Qg5++.
As was done is in 5 moves. Thank you.

Just looked at the solution and your alternative, and I thought for a moment you were correct, but nope. Since h4 is not a forcing move, it allows:

3. h4...Qb1+!
4. Kh1...Qc1 and now mate is stopped.

Sorry. The puzzle solution is (as usual) correct.
