I've just noticed i'd forgot to include GK in the engine collection repository at box.com. Thanks to the release of a fixed version by Jim Ablett, i take the opportunity to add GK there.
GK already played Ficher clock games only in Rapidroid and had 1996 ELO so far. As the fixed version is supposed to play fixed time per move too, a wider range of opponents is now possible to meet and that should ensure more games per round for better ELO accuracy. Remains to be tested and used.
The new version will not produce log files anymore, which is also preferable.
