Sloppy 0.1.1 released

It's the second version of my open source chess engine. Unlike the first version Sloppy 0.1.1 compiles also with Microsoft's compiler (makefile included). Configuration (hash size, etc.) is now also easier because there's a config file.

As for playing strength, this version should definitely be stronger by 0 - 100 ELO, thanks to improvements in search and a complete rewrite of king-attack evaluation. I haven't run enough test games to be absolutely sure though.

As always, I'd very much appreciate faster binaries, feedback, and especially a binary for Windows x86-64.

Regards,
Ilari

I was waiting for the release of this version. Let's hope I have found a new comer that can out do bugchess.

I wish I had a logo to go with it.


Found one at the page of JA.

Thanks! I've uploaded the binary to my site.

I just ran 100 bullet games against BugChess2 V1.5.2. Sloppy 0.1.1 (64-bit) got 55% of the score (41-31-28). Being a bitboard engine, the 32-bit version would of course be a bit weaker.

Nicely done. Logos seem to be important in the computer chess world.

In a 40 moves in 6 minutes match Sloppy is leading BugChess 7-3-4 here (32-bit).

They are. Everything is important that makes life beautiful.

You arent kidding, my Alfil program gained about 30 points because I used a Graham Banks logo.

Ended 14-6-12. For Sloppy I used Jim Ablett's slightly faster compile on a P4 3GHz machine.

At my time controls, sloppy is still lagging behind Bugchess after around 80 games. May be my time control (1m+1sec) is too fast for sloppy, and simple tricks like the ones Uri recently did, printing the pv etc, could help it a lot.
