Substituting one engine for another in a tournament I am running a strong computer chess engine tournament, using arena 3.5.1 All engines are playing a large number of games. One engine appears to be glitching so I want to replace it with another alternative (in terms of CPU speed / compatibility) of the same version of the engine. 

Is it possible to substitute one engine with another and retain the points that the other engine has already earned?
You can delete the old engine executable and copy a new one with the same filename to the same directory.
