Chess Opening Theory/1. d4/1...d5/2. c4/2...c5/3. cxd5/3...Nf6

Gusev Countergambit (3...Nf6!?) Gusev Countergambit Arising from the Austrian Defense, the Gusev Countergambit, named after the Soviet Master of Sports Nikolai Nikolaevich Gusev, is represented by the gambit of a pawn on c5 with 3...Nf6. In distinction to traditional openings that prioritize immediate control, Black elects to relinquish central pawns for active piece play. By offering the pawn on c5 as a gambit, Black aims to swiftly develop their pieces and pinch the action from White. The position's dynamic nature places emphasis on sharpness and quick development. White's responses White will probably reply with one of the following options: /4. e4/ - The critical approach for White. /4. dxc5/ - Accepting the gambit and the further complications. /4. Nf3/ - Inviting a transposition to one of the main Austrian Defense lines. /4. Nc3/ - Trying to consolidate the position while keeping the central tension.
