In this paper forward-pruning methods, such as multicut and null move, are tested at so-called ALL nodes. A modified version of the Principal Variation Search is introduced. It guarantees that forward pruning is safe at ALL nodes. Experiments show that multi-cut at ALL nodes, MC-A, in combination with other forward-pruning mechanisms give a significant reduction of the number of nodes searched. The playing strength of the Lines of Action program MIA is significantly increased by MC-A.
