This paper introduces a variant of clausal normal form table aux that we call “hyper tableaux”. Hyper tableaux keep many desirabl e features of analytic tableaux while taking advantage of the central idea fr om (positive) hyper resolution, namely to resolve away all negative literals of a clause in a single inference step. Another feature of the proposed calculus is th e extensive use of universally quantified variables. This enables new efficient fo rward-chaining proof procedures for full first order theories as variants of table ux calculi.
