well, the PV has been cut off now to 16 moves and was constructed from the TT,
as far as the referenced optimal move answers still are to be found in cache.

I am in the middle of Smirf's development. Smirf actual beta B-0.3.2 thinks:

(18.01) means: the intended maximal depth is 18, result is from move 1.

The maximal depth could be extended whithin the deescalation search, but mostly
the search tree would be pruned by Smirf's own method (no nullmove pruning!).

I think that 3 1/4 minutes are not that fast here. Smirf is still a baby.
