Stockfish 6 is out

Stockfish 6 is now available with Syzygy tablebase support. It is 50 ELO stronger than Stockfish 5 in self play. You can download Syzygy bases via torrent from Olympuschess.

EDIT: I ran a 7-game match of 5 minute games pitting SF6 against Komodo 8 using the Rybka2 opening book and the result was SF6 won by a score of +3 -1 =3. As usual SF's evaluations consistently ran higher than Komodo's. So, again as usual, SF's numeric evaluation does not directly compare to that of other engines which can be a tad annoying. I know that K8 is NOT optimized to play at a fast time limit; I am unsure of SF in this regard. All of which renders this little experiment useless, but still...  It will be interesting to see how things work out on the engine rating lists.
