I wonder >how many programs use this approach? I was wondering about this answer too. I guess William maybe confused this with a static exchange evaluator? William, do you really use this idea in your normal quiescence search? If so, what are your experiences with this? At least I am using this approach only in SEE, in normal quiescence I'm doing it in the same way as described by Roberto - using the SEE as an enhancement to eliminate some seemingly loosing captures.
