Changing the code could make the program stronger in certain situations and weakers in other situations. While testing, it is possible that the situations in which the new version could be weaker never appeared on the board, leaving the impression that overall, the new version is better and stronger. There are several examples of this : is Fritz 4 stronger than Fritz 3? ; on a Pentium, Rebel 6 looked stronger than Rebel 7, etc. So, knowing the code doesn't really help about that. Serge Desmarais
