One identical draw, the 2 C18 games. I count (CB7) 6 identical games and 7 more
games (CB7 again) that would have been identical if the operator would have
terminated them at the same move. Of these 13 games, 9 are won by Fritz 5 and 4
are draws. I post the double games below.
Counting all 40 games, Fritz 5 scores 79%. Counting the 27 different games,
Fritz 5 would have scored 77%. No big difference, I agree.
