If the characteristic line of this property is to be out of phase between two programs, i can imagine that one is a better blitzer but the other the better medium time player. And what about fast against slow with "more" or "better" knowledge. At blitz time control the the linear speedup (fast/slow) may be more important. But due to superior branching factor at sime time the "better" knowledge pays off and the match tilts. Gerd
