Is it possible to force checkmate with King, Knight, and Bishop vs. King? If a King, Knight, and Bishop are pitted against the opposing King, is it possible to force checkmate? I find it very hard to do, enough so that I'm not sure whether there's a clean method.
Yes, mate can be forced in 33 moves from nearly any position, according to Wikipedia.

See the standard "w" maneuver cited in that article.
