I've got a book titled "Men and Intelligent Machines" by Jeremy Bernstein ( edited by Adelphi in Italy) where in chapter "3.Programming Intelligence" we can read (translation from italian): (...) "A famous example is the game that Bobby Fischer, thirteen years old, played against the American master Donald Byrne - for many experts the most beautiful game of the century (1956, New York). At 17th move , for reasons evident only to him, Fischer sacrificed the Queen. The resulting combination was so deep, that the mate ( that Fischer should have seen from the beginning) came 14 moves later. It should be very interesting to repeat the game with Belle in place of Fischer, to see if the program using its method should be able to see the mate combination - but it's seems highly improbable" (...) Now I've tried this wonderful sac with Fritz7 and with my wonder...it finds the complete sequence of moves , not until the mate because of variants, but the winning sequence was found. Here is the position at move 17 (black to move) : Byrne,Fischer New York 1956 : [D]r3r1k1/pp3pbp/1qp3p1/2B5/2BP2b1/Q1n2N2/P4PPP/3R1K1R b and the pgn : [Event "New York Rosenwald"] [Site "New York"] [Date "1956.10.07"] [Round "0"] [White "Byrne,Donald"] [Black "Fischer,Robert James"] [Result "0-1"] [Eco "D97"] 1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.d4 0-0 5.Bf4 d5 6.Qb3 dxc4 7.Qxc4 c6 8.e4 Nbd7 9.Rd1 Nb6 10.Qc5 Bg4 11.Bg5 Na4 12.Qa3 Nxc3 13.bxc3 Nxe4 14.Bxe7 Qb6 15.Bc4 Nxc3 16.Bc5 Rfe8+ 17.Kf1 Be6 18.Bxb6 Bxc4+ 19.Kg1 Ne2+ 20.Kf1 Nxd4+ 21.Kg1 Ne2+ 22.Kf1 Nc3+ 23.Kg1 axb6 24.Qb4 Ra4 25.Qxb6 Nxd1 26.h3 Rxa2 27.Kh2 Nxf2 28.Re1 Rxe1 29.Qd8+ Bf8 30.Nxe1 Bd5 31.Nf3 Ne4 32.Qb8 b5 33.h4 h5 34.Ne5 Kg7 35.Kg1 Bc5+ 36.Kf1 Ng3+ 37.Ke1 Bb4+ 38.Kd1 Bb3+ 39.Kc1 Ne2+ 40.Kb1 Nc3+ 41.Kc1 Rc2+ 0-1 w.b.r.
