OpenChess

New release for SF 2.0.1

Changes:

• All the changes in the regular Stockfish 2.0.1
• tbhits are now sent to the GUI
• ProbeOnlyAtRoot is now false by default because it doesn't work well. Turn it on to double the NPS, though tablebases might not work well (it's a bit finicky).
• GaviotaTbCache is now 32MB by default, I thought 128MB was a bit high
• My compile doesn't require extra DLLs anymore.

At some point I might make the TB probing better/more efficient/less buggy. What's a good engine to study for implementing (Gaviota) EGTBs?

Anyway, here's the download, with the source and a hopefully fast 32-bit Windows executable:

The Makefile might be MinGw-specific, so if you're compiling it yourself you may have to alter the LDFLAGS variable. Sorry about that.

Hello Peter,

Thank you for your efforts with this, they are much appreciated.

The Gaviota website contains a list of engines (and GUI's) which support Gaviota tablebases. Of these, both Daydreamer and Umko are open source, so I would suggest starting there.

Best regards
Russell

Thanks, I'll check them out.

Peter

This is great, thank you Peter. Have you ever tried http://mingw-w64.sourceforge.net/ to build 64bit versions?

I have (for my 1.9 version). IIRC, it's missing some header files that Stockfish uses. I might give it another try, or I might use VC++ 2010 w/ Windows 7 SDK.

In about 24h 40m, this thing has been downloaded 130 times! Thanks everyone!

Of course, if it becomes too popular, I might actually have to do some work on it and make the probing better....

Peter
