This position is now part of the Arasan Chess Test Suite!! .The new program Deep Hiarcs 13.2 does much better than Chessmaster 9000 on this position , requiring a mere 32 minutes 46 seconds on my Dual Core 1.83 Notebook.It needs 24 plys vs the 18 that Chessmaster needed but it gets there much faster :

Komodo 3!

Post by sockmonkey »

Komodo 3, my new favorite analysis engine, finds it (comparably) quickly. My hardware isn't anything to boast about, and K3 is SP, anyhow. At d=24, it moves on from h3 to Rxh5. Took about 10 minutes on my Core i7 (running in a Parallels VM on a Mac laptop).

Code: Select all

info depth 24
info depth 24 time 265252 nodes 233994905 score cp 74 nps 882157 pv h2h3 b5c6 d1d2 a7e7 c2d1 f8g8 d2f2 g7h8 f2c2 b8c8 c3e1 g8g7 c2f2 g6h4 f2b2 c8b8 e3c3 g7g8 b2c2 g8g7 c3g3 h4g6 e1c3 g7g8 h3g4 h5g4

With Stockfish 2.0.1 on a MacPro 3.33Ghz / 6 cores (2010 model), it takes about 5s at level "Game in 30 min" to focus and stick on the Rxd5 variation.

Average node/s was about 5 millions.
Looking for a nice Fidelity EAG or A/S and a Odin Encore. Please send me a private message.

Yep, Stockfish found it at d=19 after just a few seconds. Nice.

Critter 1.2 needs about 5 minutes on my cell phone to find and stick with 40.Rxd5 and finds it at D=19.
