However, good search enhancements are often counter-intuitive, but not always. If avoiding hash cuts at PV nodes is any strength improvement at all, then I wonder if it is also beneficial to avoid all pruning at PV nodes (i.e. null-move cutoffs, etc.). Reducing search instability and pruning blindness would be very good things.
