I was wondering about this nolot test position because Nf6 has been found by three different programs DT-2 Fritz 6 and Goliath Light 1.5 Nolot #9 - Ng5 r4r1k/4bppb/2n1p2p/p1n1P3/1p1p1BNP/3P1NP1/qP2QPB1/2RR2K1 w - - 0 1 Analysis by Goliath Light 1.5: 1.Ne1 Rac8 2.h5 µ (-1.38) Depth: 6/14 00:00:00 1.Ne1 Rfc8 2.Bxc6 Rxc6 3.Qf3 -+ (-1.50) Depth: 6/18 00:00:00 16kN 1.h5 Rac8 2.Nh4 Qb3 -+ (-1.49) Depth: 6/19 00:00:00 31kN 1.h5 Rac8 2.Nh4 Qb3 -+ (-1.49) Depth: 7/19 00:00:00 38kN 1.h5 Rac8 2.Ne1 Bf5 3.Bf3 -+ (-1.69) Depth: 7/22 00:00:00 60kN 1.Ne1 -+ (-1.49) Depth: 7/22 00:00:00 61kN 1.Ne1 Rfc8 2.Ra1 Qb3 3.Rdc1 µ (-1.26) Depth: 7/22 00:00:00 68kN 1.Ne1 Rfc8 2.Ra1 Qb3 3.Rdc1 µ (-1.26) Depth: 8/22 00:00:00 89kN 1.Ne1 Qa4 2.Rc4 h5 3.Nh2 Bg6 µ (-1.33) Depth: 8/22 00:00:01 169kN 1.Ne1 Qa4 2.Rc4 h5 3.Nh2 Bg6 µ (-1.33) Depth: 9/26 00:00:01 320kN 1.Ne1 Qa4 2.Rc4 Rac8 3.Rdc1 h5 4.Bg5 Bxg5 5.hxg5 µ (-1.24) Depth: 9/26 00:00:02 450kN 1.Nf6 Rac8 2.Nxh7 Kxh7 3.Rc4 Rfd8 4.Rdc1 Rd5 µ (-1.20) Depth: 9/27 00:00:05 1274kN 1.Nf6 Rac8 2.Nxh7 Kxh7 3.Rc4 Rfd8 4.Rdc1 Rd5 µ (-1.20) Depth: 10/27 00:00:05 1294kN 1.Nf6 Bf5 2.Ra1 Qb3 3.Nd2 Qxb2 4.Bxc6 gxf6 5.Bxa8 Rxa8 µ (-1.18) Depth: 10/28 00:00:06 1714kN 1.Ne1 µ (-1.07) Depth: 10/28 00:00:06 1921kN 1.Ne1 Rac8 2.Ra1 Qb3 3.Bxc6 Rxc6 4.Rxa5 h5 5.Nh2 Bg6 µ (-0.88) Depth: 10/28 00:00:08 2504kN 1.Rxc5 µ (-0.77) Depth: 10/30 00:00:10 3115kN 1.Rxc5 Bxc5 2.Rc1 h5 3.Rxc5 hxg4 4.Ng5 Qb1+ 5.Rc1 Bxd3 6.Rxb1 Bxe2 7.Bxc6 ³ (-0.36) Depth: 10/30 00:00:11 3634kN 1.Rxc5 Bxc5 2.Rc1 h5 3.Rxc5 hxg4 4.Ng5 Qb1+ 5.Rc1 Bxd3 6.Rxb1 Bxe2 7.Bxc6 ³ (-0.36) Depth: 11/30 00:00:12 3934kN 1.Rxc5 Bxc5 2.Rc1 Ba7 3.Rxc6 Bf5 4.Ngh2 Qb1+ 5.Bf1 Rfc8 6.Rc4 ³ (-0.37) Depth: 11/30 00:00:15 5130kN 1.Rxc5 Bxc5 2.Rc1 Ba7 3.Rxc6 Bf5 4.Ngh2 Qb1+ 5.Bf1 Rfc8 6.Rc4 ³ (-0.37) Depth: 12/31 00:00:18 6613kN 1.Rxc5 Bxc5 2.Rc1 Ba7 3.Rxc6 Bf5 4.Ngh2 Qb1+ 5.Ne1 Bxd3 6.Qxd3 Qxe1+ 7.Qf1 Qxf1+ 8.Nxf1 ³ (-0.39) Depth: 12/31 00:00:23 9235kN 1.Rxc5 Bxc5 2.Rc1 Ba7 3.Rxc6 Bf5 4.Ngh2 Qb1+ 5.Ne1 Bxd3 6.Qxd3 Qxe1+ 7.Qf1 Qxf1+ 8.Nxf1 ³ (-0.39) Depth: 13/38 00:00:39 17395kN 1.Rxc5 Bxc5 2.Rc1 a4 3.Rxc5 a3 4.Qf1 Qxb2 5.Bc1 Qb1 6.Nd2 Qxd3 7.Qxd3 Bxd3 8.Bxc6 = (-0.17) Depth: 13/38 00:01:16 33422kN 1.Rxc5 Bxc5 2.Rc1 a4 3.Rxc5 a3 4.Qf1 Qxb2 5.Bc1 Qb1 6.Nd2 Qxd3 7.Qxd3 Bxd3 8.Bxc6 = (-0.17) Depth: 14/43 00:02:12 65575kN 1.Rxc5 Bxc5 2.Rc1 a4 3.Rxc5 a3 4.Qf1 Qxb2 5.Bc1 Qb1 6.Nd2 Qxd3 7.Qxd3 Bxd3 8.Bxc6 ³ (-0.47) Depth: 14/43 00:02:45 80416kN 1.Rxc5 Bxc5 2.Rc1 a4 3.Rxc5 a3 4.Bc1 Rac8 ³ (-0.60) Depth: 14/43 00:04:03 117075kN 1.Nf6 ³ (-0.49) Depth: 14/43 00:09:26 295763kN 1.Nf6 Bf5 2.g4 Bxd3 3.Rxd3 Nxd3 4.Qxd3 gxf6 5.Rxc6 Qxb2 6.Bxh6 fxe5 7.Bxf8 ³ (-0.38) Depth: 14/44 00:13:32 404418kN (Lee, Pensacola, FL 29.08.2001) I wouldn't say Commercials are better than Deep Thought or Blue but when Goliath finds the move quicker it sure adds fuel to the fire.

Watson Research Center Followup-To: rec.games.chess Lines: 251 Sometime ago, the following 11 positions collected by Pierre Nolot were posted to rgc. Pierre claimed that no computers can solve any of them in reasonable time (and no micros in even a few weeks). A long while back, he might be right. At this point, a few of them are solvable even under tournament time control. The ones that we tried overnight are all solvable in a few hours. DT-2 was searching around 3 million nodes/sec during the runs. The time probably would be reduced by 5-30 times for the harder problems if the machine has a better quiescence search. 9 ;r4;r1;k/4;b;p;p;b/2;n1;p2;p/;p1;n1p3/1;p1;p1bnp/3p1np1/;qp2qpb1/2rr2k1/40 White to move 8 R * - * - R - K 7 * - * - B P P B 6 - * N * P * - P 5 P - N - p - * - 4 - P - P - b n p 3 * - * p * n p - 2 Q p - * q p b * 1 * - r r * - k - a b c d e f g h Source: unknown.
