Fruit2.2 Uri can see at small depth that Rxd2 is bad and if it did not see it
then it is possible that it lost the game because of hash bug.
Unfortunately I could not reproduce the bug but I did not try to replay all the
game but only the last moves.
It is possible that history pruning=50 increases the effect of the hash bug so
this is the reason that fruit2.2 Uri is weaker at long time control but it is
also possible that the hardware of somebody in the CEGT team is broken and I
cannot reproduce the small depthes that Fruit Uri got in previous moves at CEGT
time control.
It is also possible that Fruit WCCC is different than Fruit2.2 and there is a
bug in changing parameters in fruit WCCC that is not in Fruit2.2
I wonder if you have a logfile of the relevant game that you can send to Fabien
so he can reproduce the problem.
