The Falkbeer Countergambit arises after 1.e4 e5 2.f4 d5 (ECO C31). Instead of accepting the gambit, Black strikes back in the centre, opening the position and going for a quick initiative.
The idea is to exploit the weakening White has made with f4: after 3.exd5 e4 the black pawn on e4 cramps White while Black leads in development. The play turns sharp and tactical.
An active, principled answer to the King's Gambit for anyone who wants neither to accept the sacrifice nor to play passively, but to seize the initiative at once.
