New Opening Line: Vienna – Orolov Gambit (e4 e5 Nc3 d5 exd5 c6!)


There's no way this is sound, but it may trick some players and especially so in blitz or bullet. I don't think I'd use this opening at my level, but maybe in unrated games, I could try it just for fun. This opening is unsound because it just gives up too much material without enough compensation and white is much better.
In this game you shared, 7. Nxe5 was far too greedy though. White already has more material, so they should prioritize king safety and piece development. I'd recommend Bc4 and castling, or Bb5+ to develop with tempo and then castling. If white castles with the extra material, then their opening is to their advantage here.

Like many counter-gambits it's an interestingly creative idea if accepted. Like many counter-gambits, one questions how Black might avoid serious disadvantage if White declines. For example:

In neither case is the game over, but in neither case do I much fancy Black's position.
I wish it were otherwise. My heart is in the era of Andressen and Spielmann. But my head is mindful of Neumann and Capablanca [et seq.].
