PLO final table hand

[BlackAces]

Final table of today's PLO $20+$2 at Stars. I'm 7th out of 9 in chips, with about 8000. Two others around my size, two others slightly larger, the rest are significantly larger. Blinds are 400/800.

Second hand of the table. It's folded to one of the small stacks, who raises pot (about a third of his stack) from CO-1. Folded to me in the SB with K[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/diamond.gif[/img]7[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]. A raise would get us all-in before the flop. I have no specific read on the other player, as he was playing at the other table before merging.

Raise, call or fold?
