The Evolution of the Benko Gambit

Our November Chess Life infographic honors the legacy of Pal Benko by sketching the evolution of his most famous creation, the Benko Gambit. Here, in this extended web extra, we expand upon what appears in our memorial issue, giving some more details about the six positions provided there. Position 1: Taimanov vs. Bronstein Zürich Candidates Tournament, 1953
The "spiritual forebearer" of the Modern Volga / Benko Gambit. Bronstein's famous game at Zürich 1953 is widely considered the first such gambit, although Lundin played it earlier, including in a game against Bronstein, and Russian masters had analyzed it in print before Bronstein played this game.

Position 4: Dlugy vs. Cramling Brussels, 1987
In the 80s and 90s people began trying to find advantages by declining the gambit. Here Dlugy tries 5.f3, which gives White an advantage if Black goes for the standard ideas with ...g6 and ...Bg7. Eventually theory settled on 5...e6 as a good response, and while 5.f3 is still played, it is not considered critical.

Position 5: Nakamura vs. Bologan Biel, 2012
Around 2010 12.a4 (and the associated 12.Qe2) was discovered in the Fianchetto line. The idea is to put the knight on b5, the rook on a3, etc., and Black has a surprisingly difficult time coming up with counterplay. Avrukh replaced his original recommendation in GM Repertoire 1.d4 with this move in the new second edition.

Position 6: The Modernized Benko
The “Modernized Benko Gambit” has attracted flocks of Benko players, largely due to problems in the Benko proper. Black focuses on development and postpones decisions about the a6-pawn.
