This Sneaky Pawn Push Broke the Benko Gambit

The Benkö is often considered sound, but maybe that is not true.

Benko can be playable, especially in blitz, but in this game most of Black's problems came from them choosing an unusual move order.

1.d4 c5 2.d5 d6 is hinting at a Benoni Schmidt rather than a Benko. Then the attempt to transpose back to a Benko with 5...Nf6 backfires badly. In the Benko move order, 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6, here 5...d6? would be a serious mistake throwing all the thematic justifications for the pawn sacrifice to the wind. As Yermolinsky said in "the road to chess improvement", the Benko offers long-term positional compensation but obtaining it depends initially on short-term factors, as a development advantage (preventing White from castling being a major component of that in the main line). Let me quote his conclusive sentence from memory : "Without that you get a Benoni a pawn down. Nothing more, nothing less."
The rest of the game is definitely a textbook example of how to beat the pawn-down Benoni. I wouldn't refer to the Benko in the title of the article though, as this has very little to do with the Benko. Small detail, not intending to start a debate :D .

That’s a very good point.
From a strict theoretical perspective, you’re right, the early ...d6 combined with the delayed ...Nf6 means this never really becomes a “true” Benko. By the time Black tries to steer it in that direction, the critical dynamic ingredients (especially development and pressure on the queenside) are already missing.
And what we see here is essentially what Yermolinsky described, Black ends up with the structure of a Benko, but none of the compensation for the pawn.
That said, I still lean toward calling it Benko in the title because from a practical standpoint Black clearly intended Benko-style play with ...b5, ...a6, ...Qa5, and the game is instructive precisely because that plan collapses due to move-order inaccuracies.
So I’d say it’s less a “pure Benko” and more a good example of what happens when you try to play a Benko without the correct move order.
Appreciate the insight though.

I thought this was an interesting game to review, but I lost the thread when you were talking about Black's rooks being on a4 and b5?

That didn't happen in the game, but I was talking about how the position of Black's rooks would be almost comical if they took the knight on b5 on move 27, where they have no business in defending Black's king.

i would take the pawn and play rb7 who said ra8 is forced its a terrible move wasting a valuable tempo rb7 applies pressure to b2 and in some lines helps against b5 invasions. as for the lightsquared bishop well it can stay put or do something fancy on g4 , im not a benko player but thats how i see it. and if the queen wants to retreat it can go back to a8 ! .

By the by, the idea with a7 has been known for some years now. Srinath Narayanan included it in his 2020 Chessable course on the Catalan, for instance.

This reminds me of the b6 idea in one of the main lines: 1. d4 nf6 2. c4 c5 3.d5 b5 3.cxb5 a6 4.b6!? and white basically forces the black queen on b6 from where it will lose a tempo because of the inevitable a4-a5 push by white. Interestingly, there's lot of these ideas even in mainstream theory.
Great conversion from white in the game. a7 is certainly really unique, and at first glance seems like a rookie move. Then, you catch a glimpse of the nuances, and my, do I love these quiet positional blows!
