Other boards:
During online play, you can switch chess boards. Press Select, go to "Preferences", 
select "Board", then scroll to find twelve additional chess boards. After you have 
selected your board preference, you can only save the data when you back out to 
the main menu (offline).

Bypass the ten minute game limit:
You can bypass the ten minute game limit in all tournaments by outputting the 
PlayStation2 video signal into a VCR and recording the game. Pause game play 
and rewind the tape to the last move. This gives you a chance to study the board 
for as long as desired instead of being forced to move quickly because of a 
declining clock.
