Its all in or fold bro i would jam it in on him, your beating everything except the boat and quads,, does he have you beat or think your blufffing.. the 40 dollar looks like a defense bet, so he could be raising you weaker then you think, he could just have trips granted you only made is 3x, letting him get in cheap.

Get your money in and hope it holds! lol

Hope that helps!
