...enables the event below to take place, all in Winboard.
Granted that the four UCI engines (all versions of Shredder) participating are playing without a book at ten minutes plus five seconds. Granted I have not been able to find a way to beat the hanging problem (only with BookThinker) yet.
It still is obvious that Shredder 8 is something special, whatever the gui.
Thanks Fabien, the explorations continue.
There shall come a day when all engines can participate in one shockproof, rock solid gui. It shall be a day when all engines may stand together as one, I see it....

Until then...
Later.
