Stockfish 2.0 GTB

[Peter C]

Well, I ported the code I ported from 1.7 to 1.9 over to 2.0.

It probably isn't any stronger than the regular Stockfish, but it's more useful for endgame analysis.

Currently it doesn't probe in the quiescence search, should it? I have absolutely no experience with chess programming.

Here's the source and a reasonably fast 32-bit Windows executable.

Note for people compiling it themselves:
Unlike the previous Stockfish GTB, it doesn't require you to define a bunch of things. Smile
A simple 'make profile-build ARCH=<whatever>' should suffice.

Very well done Peter. You've now actually motivated me to finally get GTB. Thanks!

[Peter C]

Thanks, but I really didn't do much. It took me like an hour to port it from 1.9 to 2.0.

The 1.7 version was an experimental version the Stockfish team released, and I just ported that code to 1.9 then to 2.0. So I did about none of the work.

You're being too modest. No one else cared to do it so thanks for your efforts.

[Peter C]

It's true that I did next to nothing (which is quite fortunate because I know very little C++ ).

I *am* kind of surprised that it wasn't already done, especially by the Stockfish team.

I'm doing some testing (but not enough ), and so far it doesn't look any stronger (or weaker for that matter ) than the official version, but I only have a few games. I'll post the results when they are ready.

It asks for a missing DLL on my machine (libgcc_s_dw2-1.dll, libstdc++-6.dll, pthreadGC2.dll)

[Peter C]

Oops. That's what I get for trying to make a fast executable....

Download this and extract it to the same directory as stockfish.exe.

Thanks for pointing that out.

News on my test of it:
Crappy Fritz GUI crashed after a few games were played in the tournament. I'll rerun it with Arena and post the results.

Peter are you using VS.NET for compilation?

[Peter C]

Nope, MinGW + MSYS.
GCC 4.5.0

That's why I'm stuck with making 32-bit executables, there is no 64-bit MinGW that I know of.

That's what I figured. I can give it a run on VS.NET tomorrow when I'm on my dev machine, if you like.
