Qf4 - Kg6 , Nh4#
That's not mate. As far as I can tell, that becomes mate in 4.
I found this mate in 5 beginning with Qf4+:
2. Qf4# or 2. Qg5#
If the first move is knight to e5+, the 2. Qg5+ leaves Kxg5 and quite possibly looses for white.
Since people keep inflating it, I found this mate in 19. :-p
I played the correct moves, and I didn't realize that I checkmated the black king.
good puzzle, yet sort of easy
Wow. I did not see that. My inital thinking was a mate in 3:
it was too easy... I was actually looking to make sure it wasn't that easy...
very nice mate
