SB checks, BB checks, UTG checks, Hero ?

typical situation where I am unsure what to do in Omaha.

dunno much about the 2 short stacks, big stack is a loose passive marginal loser over a thousand hands.
Bet and call a raise for the shorter stacks fold to big stack be best or check behind?
Please explain a liittle what you would choose to do here.
