It is a methodology for ordering captures that requires very little "work". Pick the most valuable piece that you are attacking, then capture that piece with the least valuable piece that is attacking it... It is quite good in hardware implementations. Belle had a design that let it ask, using one machine cycle, "what is the most valuable piece under attack" and then using another cycle it could ask "what is the least valuable piece that attacks that square?" It fails in obvious places. IE you would try QxR, even if the rook is defended, before you would try QxP when the pawn is "free" for the taking.
