[Spock]

Improved Crafty off to a good start.

Yes, if Crafty keeps this up, it will be promoted to Division 1

Scorpio 2.3 has replaced Scorpio 2.2.

I'm still curious why this is using a 32 bit version of Crafty when the 64 bit versions are faster??? What is the point of handicapping engines that are designed around 64 bit words, by forcing them to run using 32 bit words, when the hardware appears to be 64 bit capable. This is a good bit beyond "equal hardware" because rather than running all in 64 bit mode (and all would see some improvement due to the extra 8 registers allowing better compiler optimization, even though true 64 bit programs will see even more benefit) and is really a "handicap match" where 64 bit engines are actually penalized.

When I move onto running 64-bit engines, I'll discard the 32-bit ones completely.
Basically, I don't want to be running tournaments that include a mix of 64-bit and 32-bit engines.
Besides, the quad that I usually run this series on only has a 32-bit OS installed.
Other CCRL testers already do mainly 64-bit testing. I'm just propping up the 32-bit 1CPU list for now.

Cheers,
Graham.

PS - Crafty 23.1 looks impressive. Well done.

17TH AMATEUR SERIES (Division 2)

Intel Q6600 Quad Core
ChessGUI
128mb hash each
3-4-5 piece tablebases
Ponder off
HS-Large Remis book (limited to 12 moves)
40 moves in 32 minutes repeating (adapted for the CCRL)
4 cycles 44 rounds
All engines 32-bit 1CPU

The top engine will gain automatic promotion and the bottom engine will face automatic relegation. The fate of the second top and second to bottom engines and perhaps others will be determined by grading matches before the next series.

OK, if you have a 32 bit O/S you are pretty much stuck with 32 bit applications.

23.1 is not bad. There is more to come, of course.

I might have overlooked something, but in looking at the current stats, Crafty appeared to not play a game in the last round??? And alfil had played 2 if I recall correctly???

The PGN shows Brutus-Crafty 0-1, but the stats shown are slightly munged.

I'll check it out when I get home and correct as necessary. Replaying the Scorpio games messed up the game order in my pgn file.

Corrected. The pgn file attached was correct already though.
