Urusov Gambit


Super fun to play. Never studied it in depth as I don't play bishop's opening all that much. Whatever little knowledge I have came from youtube and playing and trying out ideas in an engine.
But for a while I didn't even know it was from the Bishops opening because according to chess.com and lichess it can arise out of the petroff defense (1.e4 e5 2.Nf3 Nf6 3.Bc4) gambiting the e4 pawn. And I thought that was the Urusov... But most people say that the urusov is 1.e4 e5 2. Bc4 Nf6 3.d4 , which lichess and chess.com call it ponziani gambit so it all gets a little confusing...
But anyway it's a fun line to play against the petroff when you play e4 e5 king's knight and they play petroff.... if they take the pawn 3...Nxe4 you can play 4. Nc3 and play some sort of stafford gambit with white...
