Shredder usually does not score well in Blitz time control like this; however, as you demonstrated for youself, Shredder still won the match. You would tend to find that Shredder score even better in longer time control. When I first bought CT15, I wish it could beat the xxxx out of other engines like Fritz or Shredder but I was dissappointed. It just couldn't no matter how faired I tried. It goes deep very fast, but I think it occassionally misses some subtle variations and don't usually pick them up again as it goes deeper where Fritz usually can pick those up more consistently. I also found that CT15's time control is not as good as CM9000. It often ran into time trouble even when it has the advantage and ended up losing on time. The response time during last minute should be faster. Jim
