Crafty 23.2 released.

[bob]

Is my first time I try to test Crafty, and I'm finding problems with endgame tablebases, I can't manage Crafty to use it ... any help?

My rc file include:

egtb
#adaptive 750K 24M 192M 24M 48M
tbpath=c:\ajedrez\tb

Do you have a version with EGTB support compiled in? If so, it should work just fine, it does here...

[bob]

No subfolder after TB folder... Testing a typical TB position, Crafty shows 0 TB Hits and a conventional progressive evaluation.

Not very convincing. If you pick a drawn EGTB position, swindle-mode can cause this to happen.

Hello Bob,

I'm using the JA compile and Arena 2.0.1

After setting egtb on and indicate tb path on the command line parameters, the debug window shows:

9.703<--1:EGTB access enabled
389.735<--1:using tbpath=F:\Ajedrez\TB
389.797<--1:5 piece tablebase files found
389.828<--1:22274kb of RAM used for TB indices and decompression tables
389.860<--1:EGTB cache memory = 32 bytes.

but no ponder hits anyway.

... take a look:

Something's broken. The program is definitely hitting the egtb's because the PV's end in <EGTB>. I am not sure how it determines the TB hits and it might be that Crafty doesn't send the necessary data for that to show.

Crafty's logfile would show egtb hits however, so you could look there to verify things are working.

OK, thanks Bob.
I'm testing the 64-bit version now, I'll post the results in a few days.

Hi Aser,
just tested a few Crafty engines here inside Arena 2.01:

None of them using that field TBHits inside Arena - but of course you see in the line: Tbs are used - and you see it of course if you setup a 5men position which has a long mate.

Yes, I've just checked it. Since is my first Crafty testings I prefer to ask to be sure things are right.

Thanks!

Try putting "noise 1" in your crafty.rc file. Crafty does not display any pv if it does not search enough nodes.

Don't worry
What arena puts in there (tbhits) is likely to come from uci engines reporting their tb hits with the uci protocol "info tbhits"
