Maybe they think that the history pruning is not good for fruit at long time
control.:-(

Seriously,I have no time to test it in games but I found that fruit could avoid
some mistakes that it did in games if you reduce history pruning threshold from
70 to 50.

see

I think that it may be interesting if people test reducing history pruning
threshold in long time control games for fruit.

I do not know if reducing history threshold make fruit stronger in long time
control but the fact that fruit can avoid some errors with reducing threshold
suggest that people should test it.
