Hi all, Just found this interesting snippet from the old posts. I wonder what would the latest programs have to say about the position arising from the 28th move "What would Bronstein have said to this Grandmaster-draw: [Event "AEGON Mankind vs Machines"] [Site "The Hague NED"] [Date "1996.04.17"] [Round "6"] [White "QUEST"] [Black "John van der Wiel"] [Result "1/2-1/2"] [BlackTitle "GM"] [BlackElo "2535"] [BlackCountry "NED"] 1. d4 e6 2. e4 d5 3. Nc3 Bb4 4. e5 b6 5. Qg4 Bf8 6. Bg5 Qd7 7. h4 h6 8. Bf4 h5 9. Qf3 Ne7 10. g3 Nf5 11. O-O-O Nc6 12. Nge2 Ba6 13. Bh3 Nce7 14. Rhe1 g6 15. Bg5 Bh6 16. Bxh6 Rxh6 17. Kb1 O-O-O 18. Nf4 Kb8 19.

Please try the following experiment: Take you computer, choose your strongest chess-program, or if not available take a stupid program like Fritz4 (the more stupid the program is, the easier it is to mate with black out of this position), maybe with the new engine Fritz4.01. And then try to be Van der Wiel (or better not!), but try to attack whites king. To show you how this could happen, here a few examples how to do against Fritz4.01 from exactly the above position: Hiarcs4 tried it the following way: [Event "Aegon96"] [Site "testgame"] [Date "1996.04.26"] [Round "6"] [White "Fritz4.01"] [Black "Hiarcs4"] [Result "*"] ... 28.Ng5 c5 29.dxc5 bxc5 30.Nh7 Rfc8 31.Ka1 Ba4 32.Nc1 Bc6 33.Ng5 d4 34.Ne4 Rb7 35.Red1 Ba4 36.Rg1 Nd5 37.Rh1 dxc3 38.bxc3 c4 39.Ne2 Qb6 40.Bh3 Nde7 41.Rf1 Ka8 42.Qh1 Rcb8 43.Bg2 Bc6 44.Re1 a6 45.Red1 Ka7 46.Qf1 Nd5 47.Qg1 Ka8 Hiarcs4 started very well, but now it is unable to increase pressure. You can try it the materialistic way by just eating and improving the position like ChessMaster 4000 would have done it (in my own styling): [Event "Aegon96"] [Site "testgame"] [Date "1996.04.27"] [Round "6"] [White "Fritz4.01"] [Black "Chessmaster4000"] [Result "*"] ... 28.Ng5 c5 29.dxc5 bxc5 30.Nh7 Rfc8 31.Ka1 Ba4 32.Nc1 Bc6 33.Ng5 d4 34.Ne4 Rb7 35.Red1 Ba4 36.Rg1 Nd5 37.Rh1 dxc3 38.bxc3 c4 39.Ne2 Qb6 40.Bh3 Bc6 41.Rhd1 Nde7 42.Bg2 Ka8 43.Bh3 Rcb8 44.Qh1 Qa5 45.Bg2 Qxe5 46.Rd8 Nc8 * [Event "Aegon96"] [Site "testgame"] [Date "1996.04.28"] [Round "6"] [White "Fritz4.01"] [Black "Virtual-Chess WIN95"] [Result "0-1"] [ECO "C16"] ... 28.

N1e2 a3 0-1 also the french program Virtual-Chess for WIN95 has no problems to find a way through. But, there are many ways to come to Rome, e.g. the Chess System Tal-way: [Event "Aegon96"] [Site "testgame"] [Date "????.??.??"] [Round "6] [White "Fritz4.01"] [Black "CSTal"] [Result "0-1"] ... 28.
