Look closer at the positions, he's not raising out of position (Gabe is the small-blind), anyways ...

4-betting the flop let's nearly every lesser hand get away cheap so with how you've played it thus far just call and lead turn for 2/3-3/4 pot.

Another line to consider in these situations is just to lead the flop for about 3/4-pot and hope to get raised a reasonable amount so that you can dump the rest of your stack in. It's especially good if you use this line with a big draw too ... such as :Ac: or in this case.
