I have the eBook from ForwardChess: https://forwardchess.com/product/squeezing-the-q-g-d?section=Products I think it's very good and advances the debate. The current situation with the exchange variation reminds a little of the Catalan a few years ago. First these systems are recommended for white as a way to get a real plus, and with merit. Then multiple answers are found for black. Answers don't claim a refutation, but keep black in the game with chances. Which answer is best? In principle, examine all proposed answers and compare. Easier said than done. For black, find a system that you like. For white, have some kind of answer to black's choice. It's ok if it is only equal as you will be on solid ground and your opponent may not be.

	kylemeister - Thanks for pointing out Davies' book! It's been languishing in my "To Be Read Someday" pile, so I was unaware it had the Timman-Yusupov game. I went through Davies' comments, and they're definitely are on point. kylemeister wrote yesterday at 03:00:44: in his Informant notes to the Yusupov game he gave 21...Nxe5 22. b3 Ba6 23. d6 as "with compensation." It's a bit of overkill to check Timman's brief, 1995-vintage note with modern engines, but I see that his evaluation is rather modest. Stockfish considers White to be clearly winning after 23.d6. The passed d-pawn is a monster. Also, the engine prefers to play d5-d6 first and then b2-b3 since 22.b3 could be answered with 22...g5, which cuts down White's advantage a bit.

	Nernstian59 -- My comment about prep was just a supposition. I see that Nigel Davies in his QGD Move by Move book from 2017 also gave 23...Qh4"!" as leading to equality. (I'm pretty sure I came across this before but had forgotten about it.) Davies wrote that 21. d5"!?" was suggested by Timman. I see that in his Informant notes to the Yusupov game he gave 21...Nxe5 22. b3 Ba6 23. d6 as "with compensation."

	cathexis - I had a recent experience with AI that you might find amusing. It's OT relative to the QGD, so I'll create a separate thread. Dink - Thanks for your observation. It explains why I'm experiencing a bit of cognitive whiplash from all of those courses presenting a variety of equalizing lines for Black. I must have retained a lingering impression from those 80s/90s repertoire books that recommended the Exchange Variation for White. Perhaps they emphasized Kasparov's success with the line (and possibly Botvinnik's earlier employment) to create the perception that it provided a sure edge for White. And you're right - I'm eagerly awaiting the White reaction to that plethora of repertoire courses for Black. Squeezing the QGD by Semkov might be the start, though I'm having difficulties finding that book here in the US. One book seller has informed me that he's still waiting for the distributor to deliver it. kylemeister - I looked at Sjugirov-Yusupov, Qatar Masters 2014, and I agree it's possible that Sjugirov had something prepared for the game, which followed Timman-Yusupov through move 20. Sjugirov's 21.d5 is a pawn sac that's the one chance for advantage, so it could possibly be prep. However, only two moves later, his 23.d6 (instead of 23.h3) is tempting but an inaccuracy. Did his prep only go a move or two beyond the initial idea? The diagrams in Reply #3 show the critical position after 23.d6. (I'm not sure of the poster's intent for the identical diagrams. Perhaps he wanted to also show the Sirota-Sander correspondence game, which arrived at the same position). At any rate, 23...Qh4 equalizes, but Yusupov's 23...Qg5 is met by 24.Ne4, gaining a vital tempo to bring the knight into the attack and obtaining a winning position. In going through the game with Stockfish, I got the impression that Yusupov was close to equal after a dozen moves, but wound up a bit worse due to reasonable-looking but sub-optimal moves such as 15...Ng6, 16...Bg5, and 19...Bc4, even before his error with 23...Qg5. If a player with Yusupov's skill and experience can slip into difficulties where a single false step can end in disaster, the "equal" position may present some practical difficulties for Black.

	Or... the AI analysis books on it, an exciting new trend!

	I really wonder whether the pendulum has swung too far. In the 80s and 90s, we had a plethora of repertoire books overselling this stuff for White, and now we seem to have a plethora of repertoire courses probably overselling all this stuff for Black. Maybe there's now abnormal profits to be had championing this stuff from the white side once again

	kylemeister wrote on 02/04/26 at 16:41:00: "Carlsbad Structure - Complete Repertoire for Black" This got my attention also. Many new ideas for black have been advanced where he avoids or significantly delays ...Nbd7. Black can opt for ...Bg4 or ...Be6 or ...Bb4. Those systems are fine for many QGD repertoires but not those that start with an early ...Nbd7, such as the Cambridge Springs defense. I'm not sure about the Manhatan. Also, an early ...Nbd7 can be tried in anticipation of white playing Bf4 instead of Bg5. The upshot is that this relatively old line, refreshed I'm sure with new moves, does not limit black in his choice of systems.

	I was a bit struck by this from "Carlsbad Structure - Complete Repertoire for Black" from Modern Chess. 1. d4 Nf6 2. c4 e6 3. Nc3 d5 4. cxd5 exd5 5. Bg5 c6 6. e3 Be7 7. Bd3 Nbd7 8. Qc2 0-0 9. Nge2 Re8 10. 0-0 Nf8 11. f3 Ng6 12. e4 [12. Rae1?!; 12. Rad1] dxe4 13. fxe4 Be6 14. Rad1 [14. h3 c5!] The red ECO from 2004 didn't show White as getting an advantage against this kind of play. One of the games cited (as unclear, in this case) was Timman-Yusupov, Riga 1995. I recalled that Yusupov much later (2014 vs. Sjugirov) played the same way, maybe ran into a prepared improvement, and lost.
