After 17. Nd1 g5!? 18. exd5 exd5 19. Nd2, 19...Qg6 is impossible, and the light squares in Black's kingside are rather weak. Stockfish's evaluation hovers around +1.0, but the position is characteristically murky, so if the position looks acceptable to you, I would understand.


Actually, the longer I look at it, the more I like it for Black. After your continuation with 19.Nd2, my computer shows the amazing resource 19. ...Ne5!, sacrificing another pawn. 20.Qxc5 Kh8! and Black seems to have some really nice play. There are many ideas for Black, like Ne5-g6-f4, maybe followed by h6-h5; d5-d4 (opening the long diagonal) or doubling rooks on the f-file and launching a kingside attack. For example
21.h3 Rfc8 22.Qe3 Re8 and White's pieces are poorly coordinated, or
21.Ne3 Ng6! 22.Qc2 Nf4 23.Bf3 h5.

OTB I think I would really enjoy this with Black. In correspondence I wouldn't be so sure, but I'm not looking for mathematical equality. And White also has to be very precise to even get the position discussed above.

@ Lauri Torni: I disagree. The sidelines you give should be okay for Black:
4.Qc2 d6 (4. ...e6 should also be solid enough) 5.e4 b4.
4.cxb5 a6 5.b6 e6 6.Nc3 Nxd5 7.Nxd5 exd5 8.Qxd5 Nc6 leads to approximately equal and interesting positions, as far as I know. If you don't like that, 5. ...Qxb6 leads to a Benoni structure, where White might be slightly better, but it's definitely playable.
4.Nf3 can be answered with 4. ...g6, if you're fine with the resulting transpositions, or 4. ...Bb7, which is known to be solid. Maybe there is nothing wrong with 4. ...b4 here, either.

The two lines you give against the modern Benko 6. ...Bg7 are of course critical, but also interesting. I believe in Blacks compensation here. One funny line:
1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6 g6 6.Nc3 Bg7 7.e4 0-0 8.e5!? Ne8 9.h4!? Nxa6!? (9. ...Bxe5 10.Bh6 Ng7 might objectively be better) 10.h5 d6 11.e6! Nb4! 12.a3! fxe6 13.hxg6 hxg6 14.Rb1! Rxa3! 15.bxa3 Bxc3+ 16.Bd2 Nxd5 17.Rb3! Bxd2 18.Qxd2 Nef6 and White should be objectively better, but tables can quickly turn if he's imprecise.

Benko has a long time been a practical weapon the correctness of which has been more or less suspect. To quote (and slightly modify) my post from 9 years ago: 

I have played benko 35 years. In the good old days people took the pawn and I was winning almost every game. Nowadays benko feels very different.

Glenn Flear puts it well: "Again we see the problem for Black in the Benko Gambit Accepted: If White is well-prepared, he can keep Black's dynamic activity in check and gradually make progress. This explains why top level players are reticent to play the Benko on a regular basis: Black's winning chances are perhaps not much better than in more 'solid' openings and he may have to play many moves with little to show for the pawn deficit."

Benko is nice against lower rated players, but what openings are not. Also, how often does one nowadays meet comfortable benko-like positions, when white has so many nasty ideas such as 4.Qc2, 4.Nf3, 5.b6 and 5.e3? Moreover even the "real benko" variations with 5.ba are somewhat better for white (g3: 10.Rb1!, e4: 12.a4!)  The modern benko with 6.-Bg7 is not a perfect answer either: there are both 8.a7 and the very dangerous 8.e5, 9.h4 -idea.

Benko is also very committal. You cannot play fluent positional chess: at some point you often just sit and wait, or you decide to make a highly committal -c5-c4,  -e7-e6, -f7-f5 -move when you either get some activity or lose quickly.

Finally notice that benko can be sidestepped with 2.Nf3 after which 2.-c5 3.d5 is just better for white.
  
1.Nf3! -  beat your opponent by killing his zest for life.

In your line with 9. Ra3 and 16...Qb6, Stockfish gives 17. Re1!, for instance, 17...Rae8 18. Bf1 Ng4 19. exd5 exd5 20. Rxe8 Rxe8 21. h3 Nge5 22. Nb1! and White's advantage is close to decisive.

The rook on a3 is far from misplaced (in fact, it's now quite active along the third rank), and ...d4 is countered cleanly by Nbd2, which supports f3 and keeps an eye on the weakened c4 square. White's positional play should be quite effective OTB.


Good point. If that is Black's best line, we can consider the whole variation almost refuted.
Perhaps Black should refrain from this Qe7-d6-b6 maneuvre. What about 15. ...h6 (instead of 15. ...Qd6). Both
16.Bh4 g5 17.Bg3 d4 18.e5 Nh5 19.Ne4 Bd5 and
16.Bxf6 Qxf6 17.Rd1 Nb6 18.e5 Qf7 19.Bd3 g5 seem to offer Black some compensation, although I'm not sure whether it's enough.

Of course, there remain some questions; for example the flexible 15.h3!? (instead of direct 15.Bg5) seems annoying, as it's not clear, what Black should do.


Unfortunately, after 15...h6 16. Bxf6 Qxf6 (or 16...Rxf6), a variant of the same rook uncovering idea with 17. Nd1! is quite strong. Not only is Ne3 now available, a future Nd2 will clear the entire third rank for the a3 rook.

I suspect that Black's best chances after 5. e3 might lie in 5...e6, given the strength of 9. a4! in the 5...axb5 line.


Okay, but that line with 17.Nd1 doesn't look too disastrous for Black. For example, after 17. ...g5!? (17. ...c4 might also be an option) with the idea of ...Qg6, Black seems to have reasonable counterplay. The position is quite messy, and I cannot see a clear way to a safe advantage for White. For sure, if White plays this line very precisely, he might be somewhat better, but not too much, and there are definitely practical chances for Black, no?

After 5. ...e6 there is the annoying 6.dxe6 fxe6 7.Nc3 d5 8.Nf3. After 8. ...c4, Black's position looks rather unhealthy to me.


After 5...e6 and 8. Nf3, I thought Black wasn't necessarily forced to play 8...c4. But even after simple development with 8...Be7, it looks like White maintains a significant edge with something like 9. b3 O-O 10. a4. 

After 17. Nd1 g5!? 18. exd5 exd5 19. Nd2, 19...Qg6 is impossible, and the light squares in Black's kingside are rather weak. Stockfish's evaluation hovers around +1.0, but the position is characteristically murky, so if the position looks acceptable to you, I would understand.

In general, I'm astonished how critical this 5.e3 line seems to be, seeing that it's comparatively unpopular and unknown.

At one time, late 1980s perhaps, 5.e3 was the main line of the Benko, at least here in the USA. Actually I was surprised that changed back to the more sedate g3 stuff, since I never saw a concrete reason given. 5...axb5 has been known to be bad for black since Benko (1973) The Benko Gambit. Pretty much white's primary idea behind 5.e3 is to park the bishop on b5 and have the trade take place there rather than on f1.

There is still some value in "old" theory, not least because it's often an unstated assumption behind "new" theory. And certainly if GMs back in the day thought A, while theory in the current day mentions only B, my non-GM opponents are going to have to do some hard thinking if I try A.

True, that does indeed look playable for Black after 15. ...Qe7!?.

Thanks for the suggestion. I had a look at the preview, but it's not really what I'm looking for. Firstly, he looks at the line only from a White perspective, thus omitting many (in part very critical) White alternatives. Plus, the line he calls "Black's most challenging move order" looks pretty obviously bad for Black, so that's not really encouraging when you're searching for a solution for black...

So far, we've been focusing on the ...g6 line, and I'm fine with that, but what do you think about Black's alternatives (5. ...e6 or 5. ...axb5)? Are there somewhere improvements for Black, or is 5. ...g6 really Black's only hope?

In general, I'm astonished how critical this 5.e3 line seems to be, seeing that it's comparatively unpopular and unknown.

I am not so pessimistic here.
After your line with 9.Ra3 e6 10.dxe6 fxe6 11.Be2 d5 12.0-0 Qe7 13.Qc2
Perunovic gives 13. ... a5 to close the queenside and concentrate on the battle in the centre.
There could follow 14.e4 Nbd7 15.Bg5 Qd6 16.Rd1 Qb6 and d5-d4 looks like a real threat for the future, also the rook on a3 looks misplaced. In an OTB game I would take Black here.

Critical lines against the Benko
09/09/20 at 14:28:54
Post Tools
Hey,
with Black, I very much like to play the Benko Gambit, but currently struggle to find satisfying lines against some critical moves.

My main problem is the line after 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.e3!?.
There, Black has several moves, but none seems to be even nearly sufficient for equality:

5. ...e6 6.Nc3 exd5 7.Nxd5 Bb7 8.Nxf6+ Qxf6 might be interesting, but 
6.dxe6!? fxe6 7.Nc3 d5 8.Nf3 c4 doesn't look good at all for Black. White simply develops naturally and plays b2-b3 at some point. I cannot see how Black can pose any problems here; isn't he just a pawn down?

5. ...g6 is often played. 6.Nc3 Bg7 7.Nf3 0-0 8.a4 Bb7 and here White has several moves, all looking excellent for him. For instance:
9.Ra3 e6 10.dxe6 (10.d6 also looks excellent) fxe6 11.Be2 (11.Qd6 is also good) d5 12.0-0 Qe7 13.Qc2 and once again, I fail to see any compensation for Black. His pawns cannot really move forward, and White can easily consolidate, rely on his extra pawn or push e3-e4 at a good moment.
Other moves, like 9.e4 e6 10.Be2 axb5 11.Bxb5 exd5 12.exd5 are surely also good for a safe advantage for White.

5. ...axb5 6.Bxb5 Qa5+ 7.Nc3 Bb7 is Black's third possibility. After 8.Bd2 Qb6 9.a4! Nxd5 10.Nf3 e6 11.0-0 Be7 12.e4 White seems clearly better. 12. ...Nb4 13.Ne5 N8c6 14.Bf4 Qd8 15.Qg4 or 12. ...Nxc3 13.Bxc3 both look horrible for Black.

So, in short, I haven't even found a line where White is "only" slightly better. Is this 5.e3-line really a "refutation" of the Benko, or am I overlooking something? What do you think about that?

Usually, the Perunovic lines (5.bxa6 g6 6.Nc3 Bg7 7.e4 0-0 8.a7!) are called critical, and probably White is objectively somewhat better there, but at least there is always some typical Benko compensation there. The same goes for the g3-lines. But 5.e3 is really depressing...
