Rodent 0.11

[noctiferus]

Hi Denis.
nice to see you here!

[pocopito]

hello pawel,

thanks for this new rodent release. a great contribution to open source chess!

And not only that, it's also GPL licensed!

Thank for your work Pawel

So that's why Adam sent me a note! Thanks Enrico.

I'm not fully charged yet, but still could spare time for the hobby.

I asked Pawel if I could sample a 64-bit as it was a bitboard engine. I didn't know Dann was at it too, but good to know that somebody noticed.

It's a blessing too as I was forced to fix my old pc to make another set of builds for AMD hardware. I think Pawel only included the ICC builds as I sent the second set a bit late after fixing my other pc.

I uploaded it in our forum.

Check-out my crappy logos ! Next could be a polyglot book.

Here's my running gauntlet:

It's a nice improvement even from version 0.10. I'll add some new opponents for the gap-filling in our list.

Thank You for the interest in this little beast. Version 0.12 is coming soon, as a friend of mine has sent me a great test position from his game. White is 1900-ish, Black 2250+, but see what happens:

Wojciech Pietrzak - Julian Gralka
Wysowa-Zdrój 2007

1. e4 c5 2. c3 Nf6 3. e5 Nd5 4. g3 d6 5. exd6 e6 6. Bg2 Bxd6 7. Nf3 Nc6 8. d4 cxd4 9. cxd4 O-O 10. O-O b6 11. Nc3 Ba6 12. Re1 Nxc3 13. bxc3 Rc8 14. Nd2 Na5 15. Ne4 Be7 16. Bf4 Bb7 17. Qd3 Bd5 18. g4 Qd7 19. Re3 Qb7 20. g5 Nc4 21. Rh3 g6 22. Rxh7 f5 23. Qh3 fxe4 24. Qh6 Rxf4 25. Qg7# 1-0

Current version cannot find 22.Rxh7 for 2 hours. Enabling history restriction to LMR got it right in under 4 minutes.

And the code is already there, only commented out in search.c and simultaneously closed behind USE_HISTORY_RESTRICTION define in hist.c.
