If not this is quite an eye opener. >Jim Hello After having many nights spent in blitz engine matches - within one computer, ponder on/off and dealing with many engine parameters choice arrays - I came to have the conviction that all these tests are perfectly *biased*. Also, I believe that no one can say which one of these two - F7 or CT14 - are the best; although I also believe that together they are the best if compared with any of the others. Yet I suspect CT14 may be at the top, but this is rather a non-rational, baseless guesswork. And I promised my-self to not spend a minute making home blitz tests any further. Karen
