Hello
First my comments are not to suggest my H performs better than yours but that it
plays very much different.
my computer is pentium 11 400 mhz and set H up to 64 meg hash time control at
40/1 hr.
One significantv difference, I use Fritz 5.32 General Book because I quickly
found out that H book is inferior ! None the less I carefully followed your
moves move by move. up to move 22 at which point I stopped the comparison as it
was very clear that your posted moves where very inferior to the moves that my H
was making. here is a summary.
at:
8. My H wanted to 0-0, forced your move !
9. My H wanted Be3, forced your move not none the less H score difference
between your H and Mine was very similiar.
18. My H wanted Bxh6 (1.73/8 your move on My H dropped score to (+1.06)
significant evaluation difference for just one move ! and your H seems to go
down hill from here on based on what evaluation by my H.
19 My H wanted h5 forced your move
20. My H wanted Rh-g4 forced your move
21. My H wanted Qc5 forced your move. by this time My H degraded indicated the
score had degraded to -0.52 where as my H was indicating 2.21 at move 20 , quite
a difference in play.
I find this very interesting cause there seems to be a difference in how Hiarc's
plays based on posts and comments that I follow here. I dont have a answer, is
it hardware differences ? i dont's know. I am positive of one statement that can
be made, I do not like the Hiarcs default book based on games played against
other programs on a well known chess server.
I would like to voice an impression concerning the play of Hiarc's verses time
control. Hiarc's plays at or near the the top in Blitz 5 min. Its superiority in
play against other programs on chess server drops as the time element is
increased. The reason may be that Hiarcs positional understanding is the plus
advantage when game moves are made rapid but the advantage diminishes at longer
time controls against deep fast searchers such as Fritz etc. In game at 30 min
Fritz5.32 and Hiarchs are very very close it seems to me
I may be wrong in both statements, but that is my experience with the program
against other programs.
