Subject: Fruit 2.1 with and without Delta & Futility pruning compared

Ran two small tournaments to see if I could discern any difference between the
stock Fruit and one with Delta and Futility pruning enabled. I wish I had more
time, this is all I could do for now. I'll let you be the judge of the results
and games.

Settings:
Pentium 3 1.2GHz, ponder off, 64mb hash per engine, time control was 3 1,
Perfect v6.1 book was used and set to "optimize".

Fruit v2.1 with no changes:

34.0 Shredder 9
30.5 Fritz 8 Bilbao
30.0 Fruit 2.1
25.5 Junior 9

Download the games from that tournament here:

Fruit 2.1 with Delta and Futility pruning enabled:

33.5 Fruit 2.1
33.5 Shredder 9
32.0 Fritz 8 Bilbao
21.0 Junior 9

Download the games from that tournament here:

Not definitive proof of anything, but I think it is starting to show a small
trend that delta and futility pruning helps.
