a safe pruning technique performed in [[Principal Variation Search|PVS]] at [[Sibling Node|siblings]] of a [[Node Types#PV|PV-node]], which are [[Node Types#CUT|Cut-nodes]], expected to [[Fail-High|fail-high]] and therefor to don't improve the score at the parent PV-node. Even more, the fail-high occurs in > 90% from the first move <ref>[[Aske Plaat]], [[Jonathan Schaeffer]], [[Wim Pijls]], [[Arie de Bruin]] ('''1996'''). ''Exploiting Graph Properties of Game Trees.''
