i'd say you're in a good position to at least split with the SB for the straight.. its likely some1 checked the flop with a set of jacks, prob the CO. (aces are unlikely b/c no raise pf)
unless a club hits the river you're prob splitin full pot with SB. if board pairs, you're prob scoopin the side pot, losin main pot to CO.

course CO could also have 24, but odds-wise its unlikely

am i close?
