Vienna Countergambit

[edit | edit source]

The Vienna Countergambit of the Vienna Game, is an variation where black plays a line similar to the Latvian Gambit but instead of the knight on f3 there is a knight on c3, the main line of this Countergambit for white is just accepting the pawn whoever there are other moves that will be on the other section of this page

Possible Moves

[edit | edit source]

3. exf5 - The theoredically best variation, accepting the pawn that black gave to you for free, whoever, after Nf6, black has the idea to play d5 and control the whole center, white needs to take a little bit of care in this position if they don't want to lose, with perfect play, white gets a slighly better position

3. Nf3 - This directly transposes to the Latvian Gambit Declined, it is not the best, but white can still get a position with more development than black after 3...fxe4, 4. Nxe5 Nf6 5. Bc4, and Stockfish 16 gives this a +0,7 advantage

3. d4 - This has a slight similarity to the Falkbeer Countergambit in the King's Gambit, since black can't take the e4 pawn because of Qh5+!, instead, black should play exd4 and white should play Qxd4, but there is also the astonishing, exf5, if black plays dxc3, white will play Qh5+ after Ke7, Bg5+ and Nf6, white can just play the absurd-looking move O-O-O if black were to take the pawn, Kb1!, sacrificing yet a pawn, and black has to deal with a lot of attacking possibilities, after d5, Nf3, white's a attack is really strong
