Junior5 is not from 1997 but from 1998.

Junior4.5 won the micro world championship in the end of 1997.
The best program at the middle of 1997 was probably Genius of
richard lang.

I believe that Genius on pIII/850 is going to lose
at torunament time control against Deep Fritz on PII400.

I also believe that Junior7 PII/400 has good chances to win
against Junior5(PIII 850) if you do not play blitz but
tournament time control games.

 You can repeat this test

I talked about the best commercial programs and not about Crafty.
