This is a good hint. In game-1 I made a typo setting the playing level. Instead of using 00:02:45 as average time I typed 00:01:45. As a result Rebel played much too fast. The positive side effect was v/d Wiel had less time to think and had big time troubles. From the GM challenge games I remember I tried a system that focus on the time control of the opponent. I will try this in game-4 and see if it is successful. Thanks. Ed >2. Set Rebel's playing style to the safest, blandest, most pedestrian level >possible.
