Oh, shit! No wonder I hadn't gotten any responses...
I forgot to mention what the flop was, namely 533.
The limp re-raise didn't work, and 5 players saw the flop. SB bet out T100 on the 533 flop. Friend mini-raises, folded back to SB, who pushes.
This whole deal with playing together was kind of interesting (pros and cons). I think it led to greater aggression, as it seemed to me like if one of us wanted to bet, that usually got done.
In this case, I actually advised a call, and SB turned over 63o to win and end our tourney.
But then we played a 2 table 6max tourney, and I like to think that our first place finish was mainly due to my aggression at the right times (as well as urging him to lay down in some spots which would have been very bad).
