Hi Derek
This all has been discussed earlier I think. To produce
identical moves is not so easy and some things must be
considered for all tests:
1) ponder=off
2) same amount of hash size
3) same playing level (thinking process may otherwise differ)
4) always clear hash tables before starting analysis
5) no other or at least identical open tasks on the PC
6) rebooting PC before each teast
Even if you follow the above instructions it will of
course rarely be possible to reproduce all moves played
in a game just because conditions used can't be repeated.
