Actually, there is some information:

Engine:
The Pirat engine uses elements of the classical procedures and heuristics in the
first stage of development; as for example Alfa beta, Principal variation
search, Quiesence search, killer -, Countermove -, History heuristic as well as
Futility Cutoffs. Beyond that, it has already some selective algorithms. The
user has access to almost all functions of the static (which only for the
starting position is computed) and dynamic evaluation (incremental in each
position computed) and therefore can change the playing strength and the playing
style (see engine manual). In the next two stages of development of the engine,
selective methods which were developed by Juergen Wolf essentially in its thesis
(diploma) will have a priority additionally to an overall increase of
performance.


Cheers
