very nice indeed :)

I was sure that after queens "exchange" the knight couldn't prevent the black king from taking the pawn. So I gave up for some time. But finally the white king goes down the way to help.. nice checkmate ^^

1. Qf4+ Ke6 (Ke7) 2. Qf7+! Kxf7 3. d8=N+! Ke6 4. Nxb7 and with Knight and King, Withes join to win, promoting the a-pawn to Queen. Very nice, indeed.

To Andrea Bassoli : I disagree with the end, white can't take a3 ; for example 3 ...Kf6 4.Nxb7 Ke5 and the road by d6-c4 is closed ; if 5. Na5, 5 ...Kd4 and road closed again.. but you don't need this pawn to win (my first comment gives a hint ;) )

You are quite right, my friend!! The problem isn't only very nice, it's really wonderful. Here's what happens if Black King tries to capture the pawn in a2: Nxb7 Ke5; Kg6 Ke4; Kf5 Kd3; Ke4 Kb2; Kd3 Kxa2; Kc2 and now the Black King is blocked! Now White Knight move towards the unavoidable mate: ... Ka1; Nc5 Ka2 (if a2 Nc3 Mate); Nd3 Ka1; Nc1 a2 (forced); Nb3 MATE!!! WONDERFUL!
