If you have a lower bound score, that says, that this is a mate to 10 or better from the root position, and you are 2 plies down in the search, this means, that the score is a mate in 9 or better from this position. If you later hit the same position 4 plies down from the root position, you know, that this line yields a mate in 11 or better from the root. I must be missing something ... Dieter
