The database programs do this for the opening, but not the nitty-gritty of the middlegame and endgame. Right? Or am I missing something? For example in a typical middlegame/endgame there are several likely moves (candidates), and a lot of irrelevant moves. Chess programs can prune out some of the nonsense moves, but not all of them. Humans can do a much better pruning job, easier & faster than computers can do, if offered that capability. It wouldn't require a very strong human player to prune properly, and speed up the analysis severalfold. I got this idea by sitting and watching the Chessmaster 6000 analysis window in progress for more hours than I care to confess!? (hundreds of hours, at least) I would estimate that it spends at least 75% of its time analyzing lines which most good chessplayers would rule out (prune) quickly -- and properly so. I'm talking about ordinary tactics as well as long-term strategy here. The chess programs just aren't very good pruners.
