  Chessical: Factor shows that the QGD can lead to overwhelming K-side attacks from an apparently depleted position.

A Vajda vs H Wagner, 1928 was a more sucessful defence

<18...Bxf3!?> 19.gxf3 would also seem to equlaize.

<25.Nxh7!> is a pretty winning line, e.g. 25...f6 26.Rg3+ Kf7 27.exf6 Qe5 28.Rg7+ Ke6 29.Nxf8+ Rxf8 30.Re7

For another main line QGD demolition see: Euwe vs G A Thomas, 1934

Mar-05-12  YoungEd: I'm no QGD expert, but maybe Black's 12th and 13th were on the wrong track, since they opened up lines before he was completely developed. Could Black have lasted longer with 15...♕xe5?
Mar-05-12  rilkefan: I thought that if black was going to play Bg4 he might as well rip off the knight (presumably seeing the game helped encourage that conclusion) - for one, it keeps the white queen off e5. (Note that in the game ...Qxe5 means black either ends up with a week e6 [after Be6] or a permanent weakness on f7 [after Bc8] or the bishop being subject to attack on h5 while being far from the critical qside.)

Anyway, stockfish turns out to like 16...Bxf3, flat equal. But it also thinks 17...Rde8 in the game line was about equal and not measurably worse than the Bxf3 line. It thinks Qg3 was a mistake: after 18...Bxf3 19.Rxf3 Nd7 (with Nc5 coming) black has an advantage of -0.4 at a depth of 26 due to pressure on the e pawn.

Black was only a pawn down and still in the game after 23...Bc8, and 23...Kg7 appears to have been somewhat better than that.

Nice closing shot.

Mar-05-12  ounos: Whoops. Black thought that he was sacrificing a pawn with 23. ...Bd5 and getting enough counterplay for it. But he opened himself to a deadly attack instead.

  whiteshark: a factor to be reckoned with

  Once: <ounos> Agreed. 23...Bd5 does seem to be the losing move. The g6 pawn is a poor defender of a piece in front of the castled king. The black bishop really needed to stay on e6.
Mar-05-12  Sem: The theme seems to be room for manoeuvres.

  kevin86: As close as black's defenders-the can do NO defending,just get in the way.
Mar-05-12  lies: What happens after 18. ... Qxe4 ?
Mar-05-12  mrbutterstylez: <lies>

I'm more than a little rusty, but I think 19. a5 would still work.

18. ... Qxe4 19. a5 Nd5 20. Rc4 Bxf3 21. Rxe4 Bxe4 22. f3 and so on. I think the ending looks all right for white after the rooks are exchanged.

I wasn't able to come up with a successful K-side attack for white after 18. ... Qxe4, but I could have missed something. :/

  Penguincw: Nice game. White's last move peels away the last piece of shelter for the black king.
Mar-05-12  gaurav33: I think if 18...Qe4.19 Re3 Qg6 20.Ne5 Rxe5 21.Re5 and white will control rest of the game.And if instead of 19....Qg6 19...Qb4 then 20.Bxf7+ Rxf7 21.Rxe8+ still white will be in winning position.

  eternaloptimist: Yes!!! My pun got picked!! I also agree that 23...♗d5?? was the losing move. Factor did a great job of taking advantage of Gilg's blunder by breaking up his castled position w/ 24.♗xf5 & the shot 25.♘xh7! This is the 1st time since May of last year that 1 of my puns got picked w/ this game.: Li Shilong vs Ding Liren, 2011 Thx cg!!
