Hi Aser, I just wanted to drop in for a moment to say thanks for testing Daydreamer. The results of your games match my own internal testing very well, which is encouraging since I can't afford the time to do long time control matches against a lot of opponents the way you're doing here.

[Aser Huerga]

You're welcome Adam, good job!

[Aser Huerga]

Upss! Another person comes to mind! I mean Aaron, of course

Daydreamer climbs up to position 29 from position 130-131 with the 1.75 64-bit version (now 2790 in CCRL 40/40 1CPU), showing an improvement of 380 ELO points regarding the 1.5 version (the old version tested in the list), 7 ELO points behind Booot and 2 ELO points ahead Delfi.

(The 32-bit version, 1 game left to enter the list, seems to be even a bit stronger, I suppose more games will bring closer both versions)
