KP - Colorado counter

The Colorado Counter arises after 1.e4 Nc6 2.Nf3 f5. ECO code: B00.

This aggressive counter-gambit offers the f-pawn to undermine White's e4-pawn. After 3.exf5, Black develops rapidly with ...d5 and aims for open lines. The gambit is dubious but creates tactical complications that can trouble unprepared opponents.
