I am basing my oppinion on a small test between Junior 6.0 Vs Rebel Tiger 12e of
50 games in 60 minutes per side, using two identical AMD 800 Mhz and Junior 6.0
won 28 games; probably the time control and speed of the computers used has a
lot to do with the result. It could be that Junior 6.0  calculate deeper than
Rebel Tiger 12e, providing faster processor and allowing a time control greater
than 60 minutes per side per game.
