I don’t think a learner can have any significance in this kind of tournament where a program plays one game at a time against different opponents for a total of 8 games. With the Powerbook on the hardisk, Thorsten would have had the same results. The learner in Fritz 5 works wonders in long matches played in sequence. In the 40:2 tournament I played, Fritz 5 played 4 matches of 20 games each. In the first 10 games of each match, Fritz 5 scored 44%. In the last 10, 61%. Looking for the same pattern in the 426 games I have from the SSDF, Fritz 5 scored 64% in the first half of the matches and 72% in the second half. This can explain the difference in Fritz 5 between manual playing, with one game at a time against different opponents, and autoplaying games in sequence against the same opponent. It can also explain why I never thought Fritz 5 was stronger than other top programs, in spite of its great comp-comp results. Right now I am playing a match Fritz 5.04 – Rebel 10.
