Eelco, I never had made a comparison between "normal" mode and "infinite
analyses" mode. I was curious and I made the following experience:
1. System: PII 300, RAM=192Mb, OS WIN98.
2. Program: Hiarcs7.32, HT=64Mb, Position Learning=OFF, Playng Style=Normal,
Selectivity=5, Contempy Value=15, Tablebase=OFF.
3. Position: LCTII, Pos14, key move= d5.
FEN "r2qkb1r/1b3ppp/p3pn2/1p6/1n1P4/1BN2N2/PP2QPPP/R1BR2K1 w kq 0 2",
4. Time to finish depth 9:
4.1. Normal: 309"(5min 09sec)
4.2. Infinite Analyses(N=6): 1000"(16min 40sec)
5. Move chosen in the end of depth 9:
5.1. Normal: d5 (Evaluation= +0.55)
5.2. Infinite Analyses(N=6): a4 (Evaluation= +0.41)
Obs: I initiated each test after to give a boot in the machine.
In the experience that I made the "Infinite Analyses" mode it's really
very slow, and the key move, d5, it was not found.
Independent of the result of that experience, I like to analize
positions using the "Infinite Analyses" mode, forcing the program
to make a move, with satisfactory results.
