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 https://tests.stockfishchess.org/tests/view/66423a1bf9f4e8fc783cba37 by using only three of the four largest terms P[3], P[18] and P[12].
