It's a strange variation on the Scotch. I honestly thought the best move in that position would be to defend the weak f7 square (4. ...Nh6, perhaps), but your 4. ...h6 seems to hold the slight advantage pretty well. It's a bit ugly that the king has to capture and lose castling rights, but that's really your only move in that position (and you're up two pawns, which is a nice trade).
Surprised that as a 1250 he didn't pause to think about mate in two after 9. ...Ne5: 10. Qd4+ Ke7 11. Qxe5#.
Ouch, just noticed 34. ...Rb8. Those back-rank mates are tricky.
I played this earlier (I'm black). My opponent did some really unexpected stuff in the opening and I blundered mate, then he just didn't take the checkmate? Idk why?
Thoughts on this 'opening'? I've never seen it before but it seems like a good trap for beginners, there're only two continuations after 5. ...Kxf7 that maintain an advantage for black (and one of them is reeeeeeaaally weird, 6. ...Kg6).
