I can guarantee you it is significantly worse, in fact. For blitz, I don't know, but then again I don't really care either since we aren't playing blitz matches that count for anything. > > >It does not prove that Crafty16.19 is really better(not enough games) but it >gives serious doubt if newer Crafty is really better. > >I also remember that Crafty16.xx was the Crafty that beated Rebel in 1 hour per >move. > >It seems that the commercial programs did big step forward from that time when >Crafty did not do it. I haven't seen my results get worse on ICC over the past N years. Things have (IMHO) remained fairly "steady-state". Occasionally there is a need for some minor tuning (IE when Gambit Tiger hit the streets) but that was done by many relatively quickly to restore status-quo. > >Uri
