The Benko Gambit arises after 1.d4 Nf6 2.c4 c5 3.d5 b5 and falls under ECO code A57. Black offers White the b pawn. Declining comes with disadvantages so White usually accepts it, at least for now. If White accepts, 4. cxb5 , Black offers the a-pawn, 4...a6. If 5. bxa6, Black's idea is that in compensation for the pawn (Black is down two, but can take back on a6 at a time of their choosing), Black gets strong pressure against White's queenside from two half-open files, an open diagonal for the bishop to control from g7, and a good pawn structure. If White wishes to avoid the positions resulting from 4. cxb5 a6 5. bxa6, then usually they accept the first pawn and decline on turn five (e.g. 5. b6). However, White also has several ways to decline the gambit on turn four. Generally, declining at this stage is suboptimal because it allows Black to play ...b4!, expanding on the queenside and controlling a3 and c3, where White's knight would like to develop. In practice, Black often leaves the tension between the b- and c-pawns to see if White will accept the invitation to transpose back into a Benko gambit accepted. With 23,569 games in the master database, it is a well-established opening choice.

Common Mistakes to Avoid
- Neglecting development: In the Benko Gambit, it can be tempting to make extra pawn moves early on. However, falling behind in development can be punished quickly, especially in open positions where opponent pieces can find active squares.
- Overextending without backup: When playing a gambit, each attacking move should have a purpose. Random checks and threats without coordination can leave your own position exposed once the initiative fades.
- Playing without a plan: Each position in the Benko Gambit demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
- Forgetting about piece coordination: Chess pieces are strongest when they work together. A single piece attacking alone is easy to defend against, but coordinated pieces can create unstoppable threats.
