Final Table of WSOP. Whats your play here?

For the purposes of this post, imagine that TV cameras are banned from the WSOP this year, there are no cameras underneath the table.

You win a satellite in to the WSOP online and show up on the first day with very little confidence. However, you go on an awesome streak, putting bad beats on everyone, and amazingly enough find yourself seated at the final table as the big stack.

You play real conservatively for an hour or two, until eventually you are down to the final 3.

Your stack is 1.5 million
Villain 1's stack is 2 million
Villain 2's stack is 140k

Villain 2 folds on the button, and you just complete to mix up your game a bit. Then Villain 1 in the BB raises it up to 150k. You smoothcall and see a flop of:

You decide to slowplay and check, only for BB to fire off another 350k. You insta-call...

and the turn comes:

You have 1 million left, BB has 1.5 million left. If you take this pot you will be chip leader and you are fairly sure you can bully BB around til you win.
