Comments:

you have two egtb commands. Only one is needed.

Mode=tournament is a special-case piece of code that is only used if pondering. It basically says "when I get ready to ponder, find the set of valid book moves for my opponent, then generate the set of legal moves for my opponent and remove the book moves. From that set, do a short ponder search to find the best non-book move, and then ponder that."

Since you are not pondering, I would remove that for simplicity.

learn 7 is also the default and should be removed for the same reason, as should "book random 1" as it is also the default.

book on is the default and should be removed

"computer" no longer does anything since crafty's eval is fully symmetric and there is no special-case computer-only code in it.

smpmt=2 and mt=2 are redundant. They do exactly the same thing so just one is needed.

The "timebook 80 8" is speculative and you can use it if you want. Makes crafty use a lot more time on the first 8 moves out of book, which may or may not be good. the "80" says use 80% more time, which might be extreme or not...

I am not following your "not crashing" comment. If it is hanging or crashing when it prints out "terminating SMP processes" then you have the old 22.0 that was replaced with the new smpnice fix because the older version was broken...

I just checked to verify and the current version on the ftp machine is the current version and I've had no reports of it crashing with ponder=off using the smpnice=1 (which is now the default).

Very special thanks again! With Peter Skinners download and his minimal .rc everything works fine, adding smpnice=1 makes Crafty use one core at thinking time of opponent up to 25%, as for myself, I can live with this. mt=2 I still have to add to Wb2UCI.eng beside engine name, otherwise Crafty uses only one core even with mt=2 in .rc
best regards
Peter.

Hi Bob,
thanks for the explanation. For these tests I used latest version from Jim - and I thougt he had changed it. Perhaps now? Hope he does it as there is a link to his versions on WBEC!!

Now I use the version from Peter - including his .rc file.

Hi Werner,

have you checked that Crafty accesses tablebases with the setup you're using?

Hi Graham,
yes, I have tested it under Arena:

Hi Werner,

I've updated my download with the revised 'crafty.rc'. I've also included
some Mingw-Gcc builds to test for anyone still having trouble. I'm still not sure
if it's my Intel build that's to blame for the problem, or the rc file, or both.
If my compile is the culprit, I'll remove it.

Just remember if using my .rc file that the command egtb assumes that your tablebases are in a folder called tb inside your crafty folder.

If they aren't, use tbpath=<path> and they access fine.

I test pretty thoroughly under Windows with all internal and release builds. The interfaces I test with are Winboard, ChessPartner and Arena. I stopped using Chessbase some time ago when I realized that no matter what I tried, a "simple" rc file wasn't good enough and even with a proper wb2uci file, Crafty played very odd at times. No doubt due to something Chessbase does.

I also make no changes to the source other than adding PS to the Crafty build number so people can distinguish my builds from others.

Hi Peter,
I just started under Arena an eng-eng match with your build
Crafty 22.0 2CPU
Naum 3 2CPU
on my dual AMD 64x2
here is the .rc file
mt=2
egtb
tbpath=J:\tbs
ponder=off
hash=384M
hashp=128M
cache=32M
log=off
exit

When I watch Windows task manager Naum 3 gets only 50 % so I stopped the match. The same happens under Winboard.
When I include the command smpnice=1 in the .rc file Crafty is unloaded before it moves...
So I wonder how do you manage to make eng-eng matches on a dual with even condions
What´s my fault now?

Which interface are you using?

If it is Chessbase, then there is nothing I can do to help as I don't use it myself for testing.

I HIGHLY recommend Arena. It simply works...
