Subject: Fractional Ply reductions for Null Move?

Author: Bruce Cleaver

All -

Has anyone experimented with dynamically adjusting R for nullmove reduction?
The idea is that some positions deserve R = 1, others R = 2, maybe some even
deserve R = 3, if your stomach is strong enough.  The value of R could be based
either on the distance from Beta, or on other factors (as used in fractional ply
extensions).

Perhaps this could save search time or boost confidence that you aren't missing
deep tactics with a static R value.

 If it has been tried before , and found wanting, well then obviously some
imposter hijacked my email ID and posted this message....     :^)
