I didn't take full notes, so there might be others in here. >>[D]r3kn1r/pp2bpp1/2p1bn1p/q2p4/3P3B/2NBP2P/PPQ1NPP1/1K1R3R w kq - 0 1 >>f3 - central pawnroller Nimzowitsch - Romih, London 1927 >>[D]2kr2nr/ppp2ppp/2b1pq2/8/1b1PP3/2NBBPP1/PP5P/R2QK2R b KQ - 0 10 >>Ba5 - big pawn centres > >This is the theory of the Chigorin Defense (d4 d5/ c4 Nc6) Right :) >>[D]2rq1rk1/pb3ppp/1p2p3/n7/3PP3/3B1N2/P2Q1PPP/3RR1K1 w - - 0 6 >>d5 exd5 e5 - piece activity > >Polugaievsky-Tal?

Fischer - Spassky, Belgrade 1992 The tactics is that fxe5 fails to 16.axb6 cxb6 17.Ne4 Be7 18.Rxe8 Bxe8 19.Bxc5+ The positional idea is that it is better for the knights to open up to position to prevent the pawnstructure from stabilizing and prevent black from getting equal in development (which would favor the bishops). >>[D]r2qnrk1/p2p3p/bpn1p1p1/5p2/2PPPP2/P2BB1N1/6PP/R2Q1RK1 b - - 0 2 >>d5 - exposing weak squares > >Yusupov? - Karpov.

Yes, Linares 1993. >>[D]1r2k2r/4bpp1/p2pbN1p/1p2p3/4P1P1/P3BP2/1PPq3P/1K1R1B1R b k - 0 2 >>gxf6 - very deep weakness in white pawn structure > >It shows that the worst pawns are the "rigid" ones (g4) that can be attacked. >This is an Anand game? Ivanchuk - Anand, Linares 1992. The move is good because white cannot consolidate his pawnstructure with h3. (I think this position is insanely hard for computers) >>[D]r2qk2r/ppp2p2/3p1n1p/5bp1/1bPQ3P/2N3B1/PP2PPP1/2R1KB1R b Kkq - 0 1 >>Kd7 - defense with king in center > >Is this a Botvinnik game? Keres - Richter, Munich 1942 Protecting the h8-rook and threatening Ne4. Black's king is fine in the centre. >>[D]q2r4/r4pk1/2Rbp1pp/pQ1p4/Pp1P4/1N2P1P1/1P3P1P/2R3K1 w - - 0 1 >>Kf1 - king acitivity for breakthrough on queenside > >The king goes all the way to the queen side to be protected and then to break on >the King Side. This is a famous game by Alekhine or Petrosian. I believe that >"King marches" are the most difficult positional manouvers for computers. Petrosian - Unzicker, Hamburg 1960 I think Yace plays Kf1 here, but not the followup Ke1 etc... -- GCP
