It does not make any sense to me. My program Sjeng being one of those, I can give at least two explanations: a) It's a misfeature which I am/was too lazy to fix. b) Because of the goofed up search the program will sometimes discover something new on the next ply and start failing high on a LOT of moves. If I can't complete the search in time, I rather trust the last ply's result than one of the new psuedo-good moves. -- GCP
