Like I said before, it is ok to play almost any junk at one of these tables if the BB doesn't raise a lot. But you gotta know what is worth it to continue. Say 8 people limp and you are in the SB with 72o. go ahead and call if the BB doesn't raise much ... you are getting 17:1!! That's just pot odds, not implied odds. Remember this is no limit. If you play 72o in the SB, you want 22 on the flop minimum to continue. It's ok that 95-97% you are going to fold ... when you flop trips or better with the huge pot odds to start with ... you will make money. It may be very rare to flop that 22 or 77 or 227 on the flop, but it does happen often enough when you get good pot odds preflop to make money on it.

If you do flop only 2pair when playing crap from the SB, go all in... you are most probably a favorite ... get all the money in with a very vulnerable hand which is a favorite at the time ... do that and you will definitely win with these hands in the long run.
