Reduce more when improving and ttvalue is lower than alpha

Reduce more when improving and ttvalue is lower than alpha

More reduction if position is improving but value from TT doesn't
exceeds alpha but the tt move is excluded.

This idea is based on following LMR condition tuning

by using only three of the four largest terms P[3], P[18] and P[12].
