Three Hands 1.2

Okay number two: final table now, Omaha Hi/Lo round, I'm in a single big blind for 4k with a stack of about 26k. There are 6 people left, big stack is around 40k, and three get paid. It gets folded around to a short stack on the button that has been playing super tight all night. He raises my big blind to 8k which leaves him 5.5k behind. I look down at 9234ds. Raise, call, or fold? Actually I think the real question here is raise or just call, but hopefully we'll see some answers.
