Pepsi Countergambit

[edit | edit source]

This Pepsi Countergambit is a rare "meme" opening which mirrors its parent, the Coca-Cola Gambit, in it's boldness and aggression:

1.g4 g5 2.f4? f5?

Although it's technical value is dubious at best and it hasn't been seen in any formal 'over the board' high level tournaments, it has been played online, with it's popularity highest in bullet chess.

It's doubled mirrored pawn structure is similar to the Beyer Gambit of the Centre Game or the Austrian Defence to the Queen's Gambit.

History

[edit | edit source]

Like the Coca-Cola Gambit, the origins of the name 'Pepsi Countergambit' are uncertain, with one of the first online mentions of its name on a chess.com forum post from 2017[1] and later mentions in various spheres of chess fandom[2]
