Hi, Last Friday (7th January 2005) I started PM on a material-only search from the starting position. This was in response to a request from Duncan Roberts: http://www.talkchess.com/forums/2/message.html?151665 On Saturday 8th, I posted a progress report: http://www.talkchess.com/forums/2/message.html?151865 I was hopeful that PM would finish 35 plies over the weekend, but it didn't happen. When I got up this morning, there had been no progress since Saturday afternoon and I didn't want to leave my PC on all day. PM had had 43 hours since it finished ply 34, but although it was still burning CPU time, there was no more output. The last I heard from PM was: 30= +0.00 00:28:36.541087088735 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 31> +0.00 01:00:13.772083574223 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 Qe7 13.d4 31< +0.01 01:09:45.04-1811636011 1.a3 31= +0.00 01:09:45.04-1811636011 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 Qe7 13.d4 32> +0.00 02:09:55.47 303672321 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 Qe7 13.d4 Kd8 32< +0.01 02:27:21.531056234340 1.a3 32= +0.00 02:27:21.531056234340 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 Qe7 13.d4 Kd8 33> +0.00 05:02:57.082077668534 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 e5 13.e3 33< +0.01 05:41:54.93-634541739 1.a3 33= +0.00 05:41:55.06-634541739 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 e5 13.e3 34> +0.00 11:36:50.42-1671302356 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 e5 13.e3 Ke7 14.Qe2 34< +0.01 13:09:24.491898767447 1.a3 34= +0.00 13:09:24.491898767447 1.a3 a6 2.a4 a5 3.b3 b6 4.c3 c6 5.b4 axb4 6.cxb4 e6 7.Bb2 Nf6 8.b5 cxb5 9.axb5 Rxa1 10.Bxa1 g6 11.Nc3 d6 12.Nf3 e5 13.e3 Ke7 14.Qe2 I'm posting this output purely for completeness. The node counts overflowed on ply 31 and the PVs are probably pretty nonsensical. Andrew
