Notably, a jack or ten gives you a straight draw as well, making your hand a favorite on the turn. That means you're really looking at 15 outs on turn since there are an additional six jacks or tens that improve your holding, and don't make his boat.

You've got a 40% or so chance to win, and 2 of 6.25 is less than 30%, so you should definitely call. You can even raise the turn if you hit a Jack or Ten (non-spade).
