Re: Perft(13) betting pool

My bet is: 1981075670675789312 (estimated value) 0000059997681255613 (estimated standard deviation) My method uses N plies of full-width search, then 13-N plies of pruned search. In the pruned part of the tree I search exactly one child node for each node. (This seemed to give a lower standard devia...

Re: Chess for Android with UCI support released

Hi, I have ported Stockfish to Android, but it is compiled as a library which is accessed using JNI. I suppose changing it to compile to a standalone program would be easy. If you are interested, the source code is in the jni directory in the droidfish tarball: http://web.comhem.se/petero2home/droid...

Re: Revolutionizing handheld chess: Glaurung 2 for the iPhon

Any plans for an Android version? No, not at the moment. Supporting multiple GUI platforms is hard work, and as an amateur with no financial motivation, it is most fun to develop for devices I own myself. Of course, since Stockfish is free software, anyone who wants is free to develop an Android pr...

Re: Stockfish seems to have trouble with KBNK endings

If we are really lucky, it is a horrible TT bug that is easy to fix, and after it has been fixed, stockfish will be even stronger than now. However, I suspect that we will not be that lucky... My wild guess is that the problem is related to not having a "delay penalty", see http://home.hccnet.nl/h.g...

Hello Eelco, I used a 64-bit version that I compiled myself under Fedora 12.

Stockfish seems to have trouble with KBNK endings
