All the competive chess engines I know of (and most non-competive ones) choose their moves by searching a tree of variations and evaluating the leaf positions. The depth of the tree is measured in plies (be careful because a n-ply search in program X means something different as a n-ply search in program Y). For the SAME engine, deeper searches (i.e. higher plies reached) usually means stronger play. José.
