Please correct me if I am wrong. I do not think that you have to worry about these games because the important results are the results of shredder4 and not the results of shredder2. shredder2 results are very good if you count only the first games of the matches against Junior6 and against tiger. The achievments of shredder2 in these games is better than tiger and Junior6 if you consider the fact thatshredder had the slow hardware. I think that you should worry about the fact that shredder4 results in cadaqu's tournament(Enrique's 40/40 games on a fast pentium) are not good and there is no clear evidence from this data and the data of the ssdf that shredder4(the engine) is clearly better than shredder2. I do not say that shredder4 is not clearly better(the results may be statistical illusion or maybe there is a problem with the autoplayer) > >Don't get me wrong.

I think that if learning tell you to play the same moves as previous game then it is better to use 0 seconds for these moves if the opponent has only learning by position(to save time if the opponent play in a different way) and the same time as previous games if the opponent has no learning and is deterministic(to prevent it from playing in a different way because of the permanent brain).
