ITM Theory Question

[Onaflag]

You've made it ITM. 3-handed. Everyone has roughly same number of chips give or take. On Stars (11), that'd be in the 4500 range. Blinds are 100/200. You've noticed and pretty much determined your two opponents are on the passive side.

You are in the SB. Button calls.

A lot of times, I'll automatically move out of the way and let Button and BB fight each other. I am starting to wonder if this is a leak.

My other two options are A) call and see a cheap flop, fold if raised, because of the passive determination or, B) get aggressive with marginal holdings because they are passive.

So, I guess I'm asking for advice on when to get out of the way, when to limp along with them and when to get aggressive with marginal holdings.
