Alright, here's the story. BB is an absolute-turbo-fish-numbnut. In the previous 4 hands, he managed to double-up, give it back, wipe out another, then give it all back again. Playing any two, calling down every board, etc.etc.etc. I have NO doubt he will be calling/pushing from his BB.

The problem is the two bigstack callers. Button is a calling-station.

What would you do here?

A - Fold
B - Push
C - Complete [assume BB then pushes....]
1) Call if uncalled by limpers
2) Fold whether called or not
--with a limper call.........
3) Call
4) Push over the top the remaining T400
5) Fold

(hope I covered all the options)
