I expect Hiarcs to suffer at longer time control because of the retaining hash
tables bug.

I analyze some games of it and I found that there were cases when it had a wrong
evaluation in the first plies because of retaining hash tables bug.

In fast games it is not a big problem because of the fact that it can get deep
enough to find a better move but at longer time control it may have big problems
because it can waste a lot of time to solve failing low problem and in the worst
case it has not enough time to solve the fail low and play a bad move.

I believe that it happens more at time control of 2 hours/40 moves when in move
38,39 or 40 it has not enough time to solve the fail low problem.
