In order to avoid wide-spread confusion, I would like to add that Bob's above statement implicitly assumes "alpha-beta" to mean "PVS/NegaScout" as employed by most chess programs. Pure alpha-beta without null-window searches and eager resolution of any fail-high/fail-low situations can of course calculate accurate search scores of all moves. But it would be horribly inefficient as compared to PVS (yet still much better than naive minimax). =Ernst=
