The idea
Why this opening works
The Benko Gambit gives White a clear route to consolidate the extra pawn without allowing permanent queenside activity. Its recurring positions revolve around the a- and b-files, queenside development, and long-term compensation, so the repertoire rewards understanding the structure as much as remembering the move order.
What to remember
- Know the first 8 half-moves of the main line.
- Understand the purpose of your key moves before adding more theory.
- Practice the branches until you can respond without move-order guessing.
