I do not know if Fruit has problems at long time control(results at 40/40
adapted to speed of PIV 2 ghz suggest that it is number 2 after shredder at
longer time control than 1 minute per game at least if you use nunn type match)
but if it has problems the logical reason that I can see is bugs in the search
that prevent it to go deep enough.

I already mentioned one bug of extending single replies too much so fruit can
solve the famous mate in 30 in 1 seconds and probably cause it to extend often
useless lines in games).

Fabien wrote that there are bugs in the search that he still had no time to fix
so he probably meant that there is more than one bug.

It is possible that Fruit is weaker at long time control(not in nunn type games)
because of positional learning of shredder but I guess that the part of
positional learning can be done by fabien.
