How about pushing the >reset-button by accident to have a crash ??? :) After the match I had a beer with Bas and we went over the possibilities. Bas doesn't have a special crashbutton so the only option we could think about was accidently hitting CTRL-F4, but that probabely would have been to obvious. Accidently tripping over the electrical wire and removing the plug from the electricity wasn't an option since TAO played on a laptop :( Tony > >Greets, Thomas > >P.S.: You can test that with the v1.50 of Quark on my homepage, Leiden-System >would be tournamentmode blitz (which means just sudden death) and operatortime >12... now start winboard with /debug and load the engine, set complete time for >game to 90 minutes and control the winboard.debug - you will see the info given >by Quark.
