Hey,

This open is pretty standard for me, btn, co and bb are big nits (their VPIP is around 15 and 3bet 2%), sb is a big fish, and overall the pool is so passive that I can make profit of this kind of open.
OTF I go large to get maximum value on the fish, and now he shoves. I think he could definitely have Qx or draw type hands, but this is still close, given that he is 40/6/0 and seems passive.
