If this is the case then I suspect that movei is faster because I remember that movei had better results relative to yace(I am not sure if movei of today calculates perft faster than List because I included in the move generator some information that is not relevant for calculating perft and the public version of movei does not calculate perft because I did not consider it as important). In all the versions that I sent to people main simply does not call the perft function in movei. The perft function is part of the source code of movei but movei never use it and only I can use it because only I have the source code. I did not know that list knows to claulcate perft. Some questions: 1)Did you use List under winboard? 2)Does winboard support the perft command? 3)Did you compare List with Chest?(I ask because I do not see chest in the list of programs that you tested).
