Was the call in MP too loose? (Noticed a lot of limping)
Would you call or fold to the all in?

it was loose, if your gonna play that, raise PF

your flush has to be live, BB shoulda raised with an A

id call

2 questions.

What reads had you picked up on BB? How had he gotten that big stack, good cards or naked aggression?

I'm also leaning towards a call here. You're most likely behind (2 pair is my guess, tentatively he would have milked the straight), but your flush should be live. Barring anything strange in answer to the questions, call.

Easy call. You're a favorite over AA. You're a favorite over 46. I think your pair of 7's might be the best hand already! If not, you've got a nice backup plan.

I think that you're in a coin flip situation here.

You have 14 potential outs which are probably good.

What could BB have:

Two pair
straight
trips
flush or straight draw
nothing

This early in the tourney, I'd fold as I don't like coin flips early in the tourney where if I lose, I'm out.

Ok, thanks for the replies guys. Here's what happened. I called, he shows 44 for a set. I catch a K on the turn for 2pair, then a diamond on the river to complete my flush. I double up, he says nh, and I'm left wondering if I made the right play or just got lucky.
