I am very impressed DJ7 might be the next program i get I think that if you want positions that programs cannot find you should not use positions when the difference between the evaluation before the move and the evaluation after the move is less than 0.5 pawn. It is even better to take only positions when the difference between the evaluation of the root position and the evaluation after the right move is at least 2 pawns so programs canot solve it by slightly different evaluation and really need search.
