Subject: Effect of iterative deepening

It seems I got PVS working. In comparison to simple alphabeta I get mixed
results. I have seen positions where PVS does 20% less nodes than ab (starting
position). However I have also seen (tactical) positions where PVS does do more
nodes than ab. I am trying to find out how that's possible, but didn't have
enough time.

The impression is that pvs is just more sensitive to good moveordering than ab.

I see that iterative deepening in Crafty. How important is it?
