That's bound to happen in some cases. If you don't notice a general speedup from following the PV, though, something is probably wrong. It's possible that you're evaluation function doesn't have very much granularity (say, if you're just counting material) so any reasonable line will produce the same score as the PV. Then the "PV following heuristic" will obviously offer no improvement. -Tom
