Hi to all. I've implemented the alpha-beta with transposition table. Please, can anyone tell me is this implementation correct

Thanks for reply Hyatt. But I have another question. How return value > alpha and < beta can be true at the end of search in alphaBetaMax and alphaBetaMin since we have this blocks: if( score > alpha ) alpha = score;(AlphaBetaMax), and if( score < beta ) beta = score;(AlphaBetaMin)?

Hello to everyone. I do not quite understand how works TT. Why do we have to check that the score <= alpha (in case of UpperBound) and score > = beta (in the case of Lower bound)?
