Hand v Moorman

Following hand took place ~a month ago with one of my students against Moorman ITM of the ACR $88 nightly. I've had a lot of interesting discussions about this spot and curious what you all think.

They are ITM with 4 tables remaining, Chris is the CL on the button with ~120bb and my student is average with 30bb in the SB. BB is another reg with 25bb.

Folds to Chris on the button who open jams all-in (for 30bb effective) covering both. What is the worst hand you'd call off with in my student's shoes from the SB?

This spot is especially interesting as you all know the solver doesn't do this with anything for 30bb, so it's a process to figure out what Moorman's range may look like for this unorthodox jam. Assuming he didn't misclick here, what do we think his jam range is and where do we draw the line for calling off?
