You are right, Gothmog uses MTD(f).  In Glaurung, I have switched to PVS, for
two different reasons.  The first and most important is that MTD(f) does not
perform well without a big hash table, which is a serious problem because
I hope to port Glaurung to handheld devices.  The second reason is that I
wanted to learn something new.  Trying out different search algorithms in
practise is a much better way to learn than to just read about them.
