Top pair in big blind

[Sandy Cheeks]

Well even though my hand memory can be kind of sketchy, I thought I would post a couple of hands from a few of my tourneys. This is a hand from the Main Event.

We all started with 5,000 in chips with 40 min blinds. Day 2 started with 36 players - 11 players left, 5 at our table, 6 at the other table; aggressive blind structure:

With approx-80,000 in chips with the blinds at 8-16 thousand with 4000 antes (2 players to my right were well acquainted with each other belonging to another regional poker club) both had been working the squeeze play on me since they had both been moved to the final 2 tables.

I was BB with -, Button calls, SB calls. 68,000 in the pot. Flop --. I bet out 40,000 button pops over the top for 80,000 and he has about 200thou behind., SB folds . I insta-call. What does the Villain have????
