It may have something to do with better move ordering, which means having to
look at fewer 'bad' nodes. This may also happen when you increase the hash
table, again it is a matter of move ordering which 'slows' down the engine.
Remember that node count is not a very valid way to account for a program's
strength, take LGG2.05 as an example, I have seen it speeding far away from
Fritz, yet it is not a very good chess playing program, it is an excellent
problem (tactics!!) solver.
