Perhaps, the GUI also looks at the score? So, when the engine, that is given a 3-fold repetion position (as happened in that game), the GUI could let it search nevertheless (which basically would follow your argumentation in this thread). Indeed, in the position that the GUI had seen (from Shredder point of view) claim of draw was possible (without asking the engine, and without writing anything to the score sheed). The GUI might look at the score reported by the engine, and adjust the GUI-decision for draw claiming accordingly. Perhaps the GUI even claimed draw, and nobody saw it (or those who saw it tried to ignore it)? Even more scenarios are possible. Regards, Dieter
