JT hand

[M.B.E.]

Middle of $150 online tourney, blinds 400/800 ante 50. My stack is 24000, one of the largest at the table.

A player with 6000 limps in EP, cutoff (big stack) limps, I have JTo on the button and limp. SB completes, BB checks (both medium stacks, around 12000).

Pot 4400. Flop 9[img]/images/graemlins/spade.gif[/img]8[img]/images/graemlins/spade.gif[/img]3[img]/images/graemlins/heart.gif[/img]. (I don't have any spade.) Checked to the cutoff, a generally aggressive player, who bets 3200. That leaves him with 17000; I have him covered by a little. What's my play?
