This happened the other night and I'm curious what others would do in this situation.

Read: BB seemed to be somewhat selective of starting hands and didn't do anything to get noticed by me as being out of the ordinary...

Sorry, no hand histories on the site I'm playing on...

$20 6-max NL
Stack sizes: BB and me both over 125BB each
My Hand: 22 on the button

3 people see the flop (BB, MP, and me all limp)

FLOP: 2 3 4 rainbow
BB pushes All In, MP folds, Hero ???
