In particular has anyone tried Illingworth's line 1.d4 d5 2.c4 e6 3.Nc3 Nf6 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 g6 ?


Radjabov played this twice as Black in last year’s World Cup and scored 1.5 out of 2 in rapid games.

Here is the win: https://www.chessgames.com/perl/chessgame?gid=1972580

At a 2000 level, defending the QGD Exchange makes it too easy for White to get a good position and for Black to have limited chances.

The relatively better technical play of an IM or GM may be needed to make it work in practice.

Of note is that Illingworth also recommended 11...g6 in the line with Nf3/0-0/h3 (which, unlike against Nge2/0-0/f3, is an old book move).  That also appeared in Tibor Károlyi's The Exchange Queen's Gambit for Black.  Dmitry Kryavkin's Attacking with g2-g4: The Modern Way to Get the Upper Hand in Chess appears to claim an advantage for White there.

There's also the Ntirlis treatment in his 1.d4 d5 book, where White seemingly has to find/know the plan of castling long, followed by Kc1-b1-a1 + b2-b4 (+Rb1?) to achieve anything, as he did here https://www.chessgames.com/perl/chessgame?gid=1924134 , but Black has some improvements along the path of course.

Such a minority attack with both players castled long puts me in mind of (yes) an old game, which I recalled from Test Your Positional Play by Bellin and Ponzetto.

There were two recent pretty well publicized games even in the old line that Carlsen "refuted" against Kramnik, with Black scoring 1.5/2, and never appearing to be in too much trouble
https://chess24.com/en/watch/live-tournaments/fide-womens-world-championship-202...
https://chess24.com/en/watch/live-tournaments/tata-steel-challengers-2020/8/1/4

Carlsen also played the Korley line at the World Blitz
https://chess24.com/en/watch/live-tournaments/world-blitz-championship-2019/3/1/...
And while the Engine yells +4 somewhere in the middle, his willingness to play it at all may or may not mean something (ok, he plays the Norwegian Rat in Blitz, so who knows)
-- Don't know if there's an actual name for it, I just call it "Korley line" based on this game https://www.chessgames.com/perl/chessgame?gid=1968792 , which he made a video about https://www.youtube.com/watch?v=AQIh-NqZKHQ

There's also the Ntirlis treatment in his 1.d4 d5 book, where White seemingly has to find/know the plan of castling long, followed by Kc1-b1-a1 + b2-b4 (+Rb1?) to achieve anything, as he did here https://www.chessgames.com/perl/chessgame?gid=1924134 , but Black has some improvements along the path of course.

I don't know anything about the Illingworth line, but if he recommends it - I trust him as an author/analyst, so I have no doubts it's quite playable as well.

It's a major opening, so yes, it will always be "fine". If you're a sitting duck, and play the same variation every game, while the entries in the database pile up, at some point you're going to run into issues - but that's the case in any opening. As long as you jump between subvariations here or there, and aren't too concerned with playing a boring "no-play" line as in the l'Ami game, I see no issues with the QGD Exchange. If you're below 2200 or w/e, then "anything" works as a main response anyway, and certainly the QGD is rather on the "sound" than on the "bogus" end of the opening spectrum.

SuperGMs don't visit it much anymore, since there are even *fewer* issues in the Nimzo, but I mean.. that applies to pretty much any opening under the sun (aside from the Berlin, perhaps?), so it doesn't exactly disqualify the good old QGD.
