I usually obviously usually re-raise with AA, but UTG doesn't have many chips, and I'm hoping that I can win more. Big stack (SB) has played every hand so far, meaning he's a luckbox donkey, so I expect a call from him. Any suggestions?

Thanks,
Will

P.S. I know that the move here is a matter of preference/reads/etc, but I'm usually an MTTer, so I don't know if there's a good rule of thumb for this in STTs (especially PP STTs given the large blind:chip ratio).
