I'll ponder that one later. > Now, regarding the non-empty "show escape" result when the user isn't in > check... here's an example transcript: Cheers, seems one of the variables was being used for two purposes, and would sometimes result in erroneous results if the king wasn't in check. My guess is no one looked at "show escapes" closely enough, and the results were fine when the king was in check, which is when the search calls it. Tentative fixes have been committed to CVS for 5.07 for disambiguating "hint" and fixing "show escapes".
