Not all latvians get crazy, this one was a more calm, positional one since white declined the gambit. Perhaps whites best option is to accept it to play for a win.
So far, this gambit still works for me. I wonder at which rating level it will stop working..
... there's also e4 e5 Nf3 Nc6 Bb5 f5, which is more advisable.
Do you play it regularly, and does it still work if white goes for italian instead of spanish?
I don't really play e5 that much, so no, I don't play it regularly. It only works against the ruy lopez, not the italian. I mostly play the caro-kann with a few sicilians thrown in there. I have a ton of model games on my YT channel if that interests you:
