Everyone uses some variant of Alpha-Beta.

There is a paper that shows that MTD(f), C* and other variants can all be
formualted in terms of a common architecture.

Basically the same is a big stretch though.

The important thing is the branching factor.  The best programs will have (on
average) a branching factor less than 3 most of the time.  The alpha-beta
branching factor is about 6 in a perfectly ordered tree.  Therefore, there is
some pruning besides alpha beta going on in all the really strong programs.
