I didn't take full notes, so there might be others in >here. SofMCS is a hell of a book (by J.Watson). One of the best of the last years. PPinC, I haven't read it all but it is classic one. There are many positions from several test suites taken from that book, for instance, Bratko-Kopec. >>>[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? > >Yes > >>>[D]r1bq1rk1/1pp1bppp/p1p5/2n1P3/3N4/2N5/PPP2PPP/R1BQR1K1 b - - 0 1 >>>f5 - blockading to restrict activity >> >>This move is amazing.

I cannot understand how Spassky let Fischer get this position. Fischer has played a similar position before and Dvoretsky copied that in another game. Spassky is an expert of this opening and for sure know this two games. I am going to dig those two games. It migh be interesting to test computers on those two. I think it is more for fun than anything else, though. >>>[D]r2qnrk1/p2p3p/bpn1p1p1/5p2/2PPPP2/P2BB1N1/6PP/R2Q1RK1 b - - 0 2 >>>d5 - exposing weak squares >> >>Yusupov? - Karpov.

Very interesting to test high level king safety! >>>[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.

That is the problem with this kind of positions. The computer has to see a plan and the first move is no guarantee that it is seing it. Some computers might play Kf1-Kg1... Thanks for the positions, Miguel >-- >GCP
