The winning continues. After I starting spewing early, I was able to right the ship and start taking back my money. The big hand was this one.

That was my big hand for the session and the one that made me almost all of my profit. Villain's big mistake was obviously not re-raising with the trip 4s on the turn. By just calling, he game me my inside straight. When he re-raised me on the river, I wasn't exactly sure what he could have, but I knew I had the nuts.
