looks like a smothered to me.
Petrosian called it "Oops!", in 1962.
where did you get my last game as white?
Wow. This looks pretty clever especially for a blitz game.
You're not thinking of Phildor are you? Thats the only thing that springs to mind with smotherd mate. Either way good game and great mate.
Yeah, it looks like the schematic of the Blackburne Shilling Gambit to me. Supposedly Blackburne offered games to amateurs, at stakes of a Shilling, and would proceed to win by this wily if dubious Gambit. This is just chess legend, and I doubt if it is true.
It's very similar to the Costage Trap.
Yes, definitely Blackburne pattern, did you aim for it or it just happened ?
