Strategy Question about playing from big blind

[Matt Williams]

I play in a lot of live STT ($20-50 buy ins) where a lot of people like to limp in and see the flop until the later stages of the tourniment. How do some of you guys like playing mediocre hands from the BB? Do you like checking and seeing the flop for free, or being aggresive and pushing? Let's say the blinds are 100-200, 4 limp in and I have J6o, w/ $1,200 left after posting 200.

The reason I am asking about the BB is because if I decide to just check and fold, I only have to post another 100 and then get 8 free hands.
