I feel like an [censored]. I play these suited crap hands to get into exactly this situation and then I fold [img]/images/graemlins/frown.gif[/img]
Here is what's going on:
- UTG: very tilted, his hand range goes from nothing to JJ, I think he would push all-in against the minraise if he had overpair/even flush draw!
- CO: he didnt seem reckless, had not seen another minraise before, feared him most in this hand, was not sure if he would minraise a set with a flush draw + straight draw out there, but hey these are party idiots
- Button: Calling idiot, he would call a bad flush draw or one pair hand here...

So I have three types of actions:
a) Fold
b) Push All-in
c) Call, hope that UTG pushes all-in, see how the action develops and then call/fold depending what CO does
