what is the problome with 4 move checkmate?
eh... could use it in bullet or hyper and it works if they are premoving
Yea I won loads in bullet

1. e4 e5 2. Qh5 Nc6 ( 2. ... g6 would allow the king and rook to be forked) 3. Bc4 Nf6 ( 3. ... g6 4. Qf3 Nf6 would be better, with a threat of 5. ... Nd4 and 6. ... Nxc2+ ) 4. Qxf7#.
So it turns out that this opening is good for black.

Qh5 is only a good move if black falls for it. Otherwise, your queen is in a rather precarious situation, and black can gain tempo.
