Available Lines

Benoni Defense: King's Indian System

After 1.d4 Nf6 2.c4 c5 3.d5 e5, Black continues with 4...d6 and 5...g6, adopting a King's Indian setup within the Czech Benoni structure. This system combines the closed center of the Czech Benoni with the fianchettoed bishop typical of the King's Indian Defense. Black aims for a solid, flexible position with good piece activity and potential for kingside expansion.

Benko Gambit Accepted

After 1.d4 Nf6 2.c4 c5 3.d5 b5, White accepts the gambit with 4.cxb5, and Black continues with 4...a6 to regain the pawn with pressure. This is the main line of the Benko Gambit, where Black's compensation for the sacrificed pawn includes open a- and b-files, active piece development, and long-term positional pressure on White's queenside. Black aims to create lasting initiative and attacking chances.

Benoni Defense: Old Benoni, Schmid Variation

After 1.d4 c5 2.d5, Black continues with 2...d6 and 3...g6, adopting a fianchetto setup. This variation combines the early c5 challenge of the Old Benoni with a King's Indian-style development. Black aims for a solid, flexible position with good piece activity and potential for expansion on both flanks.
