Abstract
Abstract Two sets of conventional chess men (eight pawns and eight pieces per side) confront each other on three vertically spaced boards of four by six squares each, with the middle board offset from the substantially aligned top and bottom boards to provide three freely accessible playing surfaces on which the men may move longitudinally, laterally or vertically (from one board to another) according to predetermined rules.
