Just a short addition: "to cut a move" of course means to cut the whole subtree spanned by it. Hence, the only misnomer I can detect is that Peter McKenzie and you denoted a depth reduction as "razoring" although the original term "razoring" as coined by Birmingham and Kent in 1977 clearly referred to real pruning by stopping the search completely at the respective nodes (i.e. all moves get cut off). =Ernst=
