Subject: Observations on Fruit 2.2.1

When autoplaying Fruit 2.2.1 vs Shredder 8 on my 1.5 Ghz AMD 512 MB machine and
alloting 64 MB RAM for 4 minute Blitz chess, I noticed that Fruit 2.2.1 scores
about 50 elo points stronger than Shredder 8 when it uses its own Book.bin 1.4
MB opening book vs the Shredder's native Shredder8.ctg opening book. On the
other hand, Fruit 2.2.1 scores 50 elo points weaker than Shredder 8 when both
programs use the Shredder 8 opening book.

I am sure that Fruit is an excellent program and has a slightly different
playing style than Shredder with often differing evaluation scores. I also
notice that Fruit 2.2.1 is doing 50% more node searches than Shredder 8 on the
same processor with pondering off. I assume that Fruit 2.2.1 is using more
refined knowledge-based algorithms than Shredder 8. Nevertheless, the fact that
Fruit 2.2.1 does better with its own book suggests than book tuning is in
effect.

I am impressed with Fruit 2.2.1 and would pay twenty dollars more for Fritz 9 if
Fruit 2.2.1 was included as a secondary engine. I may pay the $33.xx USD fee
within the next 13 days if Chessbase doesn't include Fruit 2.2.1 with Fritz 9.

Sincerely,

Uncle Timbo

PS If Lucien could sell 100,000 copies at an extra $10.00-$15.00 USD profit from
his program bundled with Fritz 9 the guy could have a cool $1,000,000.00 USD
within one year. He could then retire to a tropical island like that fellow
Christophe Theron. Perhaps he could even buy a Jaguar.
