Sibling Prediction Pruning
Sibling Prediction Pruning,
a forward pruning technique at frontier nodes (depth == 1) introduced by Jeroen Carolus in his 2006 Masters thesis . It works like Futility Pruning, to skip quiet, none checking moves, if they have no postential to exceed the best score so far aka alpha. Carolus' implementation even breaks the move loop, assuming an ordered move list.
