9.h4 in the third diagram with forced mate in at most ten moves
Black's best move is not 3...fxe5?? which loses at least the Exchange in all variations, but 3...Qe7, after which he is still practically losing. There is a trap here: 4.Qh5+?? g6 wins a piece for Black because after 5.Nxg6 Qxe4+ the King and Knight are forked by the Queen. I have won a couple of blitz games this way, but the Damiano should not be taken seriously.
In the third diagram, 6...Kg6? loses faster than 6...d5 7.Bxd5 Kg6 8.h4 h5 9.Bxb7! (the important point of 6...d5 was that the Bishop defends f5 from c8) 9...Bd6 10.Qa5 and White wins the Rook on a8, but does not have an immediate mate.
So there is this cool opening that I wanted to learn more about. It is called the Damiano Defence. White's knight does something a little bit counter intuitive and takes the pawn, but with good reasoning, because later he will probably get the rook or screw up the king really bad. I couldn't find the variation names for these on the web so I made up my own. Of the Damiano Defence there are 2 major variations that black can play. I call them the "Cowardly King":
And the "Paramounting Pawn":
As far as I'm aware, these are the only two moves for black. Now for the big question. Given the following game what is the correct play for white?
