Less reduction for tt move. This idea is a result of my second condition combination tuning for reductions: https://tests.stockfishchess.org/tests/view/643ed5573806eca398f06d61 There were used two parameters per combination: one for the 'sign' of the first and the second condition in a combination. Values >= 50 indicate using a condition directly and values <= -50 means use the negation of a condition. Each condition pair (X,Y) had two occurances dependent of the order of the two conditions: - if X < Y the parameters used for more reduction - if X > Y the parameters used for less reduction - if X = Y then only one condition is present and A[X][X][0]/A[X][X][1] stands for using more/less reduction for only this condition. The parameter pair A[7][2][0] (value = -94.70) and A[7][2][1] (value = 93.60) was one of the strongest signals with values near 100/-100. Here condition nr. 7 was '(ss+1)->cutoffCnt > 3' and condition nr. 2 'move == ttMove'. For condition nr. 7 the negation is used because A[7][2][0] is negative. This translates finally to less reduction (because 7 > 2) for tt moves if child cutoffs <= 3.
