Within the 40 played games I had 3 games where Junior stepped over the time control. The very first game vs. Shredder 7.04 was in a totally won position with eval higher than +5 and Shredder worse than -7. Junior used 1min too much but both played on and Junior won. I counted this game as won. Of course this has introduced opinions to not count it as win. The 2nd game is mentioned above where Junior later on in the game lost anyway so no problem at all. And the 3rd game is also mentioned above. Junior calculated longer than my timeout is (60 minutes! so far I have only seen up to 50-55min for calculating on one single move, iirc Tiger or Hiarcs was it ;-)) and I had no chance to continue the game. The autoplayer interrupted and started a new game after the timeout of 60min. This game is not contained in my game collection. Why should it? It was far before move number 30 in an equal position. However, now it seems that the time bug is solved so this will not happen any more.
