Dec-22-07  Whitehat1963: What's the finish?
Dec-22-07  Karpova: Black will have to play 29...Qc2 (29...Qg6 is useless since white will play 30.h5 and drive her to c2 anyway since Qh7 would be met with Rd7+, e.g. 29...Qh7 30.Rd7+ Re7 31.Qf3+). Then the white queen will infiltrate the black kingside with 30.Qf3+ (30...Ke7 31.Qf6#) and black is defenseless afterwards.
Dec-22-07  AlexandraThess: This game shows that mr. Andersson can play very agressively when the situation requires it. But why to take the risk by attacking, when you can wait for mistakes from your opponent in the endgame?!
Dec-22-07  Chesstalesfan: Dear Alexandra , I also like this style. I remember the game Andersson-Tal in Malmoe in 1983. I ll be in Thessaloniki and Nea Raidestos 4-5 January 2008. To your opinion what was the main error of the black in this game?
Dec-25-07  Chesstalesfan: Merry Christmas. Kala Xristougenna! I am still wondering about this game. It seems to me like a kind of magic. Greenfeld plays well the opening. He even wins a difference in the 13th move. No apparent mistakes then. At least unseen to me, if any. It might be the Troyan horse attack 19. Nf7, after which the pieces of Mr. Greenfeld are totally disorganized? I gave one of my students the subject of applying the Entropy concept in Chess, .ie. the Boltzmann equation which is valid for both entropy and Information. I think this game is a nice candidate of consideration in his Thesis..
Dec-25-07  Ziggurat: <Chesstalesfan> It does look odd that white wins so easily after sacrifing the exchange. However, there were other games where Andersson also won after surprising exchange sacrifices with unclear compensation:

Keene vs Ulf Andersson, 1975

Karpov vs Ulf Andersson, 1975

Jan-03-08  AlexandraThess: <Chesstalesfan> Kala Xristougenna kai eutixismenos o kainourgios xronos!! I am sure that you will have a great time in Greece.

Concerning your question about the game, I can not really understand all of the complications following 12.b4.

  Mateo: This game was considered as one of the best games of the year by the Informator. As one can see, the game is simply lost after 14...bxc5?. There should be some improvement for Black at this point. On the all, this game should be in a book called Andersson selected best games.

  vonKrolock: Cebalo's remarks in "Informant" are too short... Only 12...♘d7 is given as alternative to <12...♗f6> - Maybe 12...0-0!? , or 12...♗f6 13.♕e3 ♗xa1 14.bxc5 0-0!?.

<19.♘}xf7>! The actual play until 21.♕xb7 is just a little combination leading to a palpable positional with compensation... The grandiose sequence would be: 19.♘xf7 ♔xf7 20.♖f4+!! ( right now with the exclamations!...) 20...♔e8 (or 20...♔e7 21.♕f3! etc) 21.♕xe6+ ♕e7 22.♕d5! (with idea of ♖e4) 22...♕c7! (best) 23.♖e4+! ♔d8 24.♗g5+ ♔c8 25.c5!! and white - a ♖ down, conducts a winning attack!
