Code: Select all
Stockfish 1.2 = Stockfish 1.1
+ merge of Glaurung 2.2 evaluation enhancements
+ new tricks in the search
- some bugs
Stockfish 1.2 Optimistic is probably the strongest and has an aggressive play but sometime it is weak with lower rated engines.
Stockfish 1.2 Default is my favorite, it has a more solid play and makes less mistakes and my guess is that at longer time controls should be good.
Please Jim, could you be so kind to make a really SUPER-SUPER FAST-FAST compile? I have expectations on this puppy. Thanks in advance.
Known issues
- As the original Glaurung, this engine is endian sensitive. Please read the README if you have a PowerPC Mac and you want to compile yourself.
- On 32 bit systems code must be compiled with -fno-strict-aliasing option, both under gcc and Intel C++ compiler, to avoid random crashes due to a pop_1st_bit() optimization. MSVC does not seem to have this problem.

Special thanks to Tord Romstad for his beautiful engine. It's a wonderful base to start from. If this engine will demonstrate stronger then Glaurung it is mostly because of the very high quality of the original one.
Thanks and happy new year to everybody !

P.S: I think this will be the last for a while, I say this to relax the worried testers, two versions in a few weeks I understand is too much
