Adjustment of the aspiration window after fail high/low. For the new bound in the opposite direction of the fail, use a weighted average of alpha, beta and best value +- delta. In the case of a fail high, different average weights are used depending on whether or not there was a best move change during the last search. The weights are determined from the following two consecutive LTC tunings.
