no point in resigning.. He could still get a good game
Nimzovitsch Opening, Colorado Gambit

Thanks for making the follow-up PGN, Amartalon

If you actually want to learn how to play the opening consider looking up GJ_Chess he has a whole video on it and how to react to some of these moves properly. I've had great success with this opening even at the higher rated plays.
Havn't been faring too well with my rating lately, but I was happy to beat this guy in 11 moves.
