Great dicussion with this hand, and tons of useful information I can use in the future. The villian's CO range was much looser than any other position he played from. After he flatted my 3bet, I was thinking he's holding a pocket pair or AK. With the flop texture giving me so many options it didn't make sense to not put the money in, even if the guy potentially had a set on the flop. After I played that hand I ran through it with HEM and saw the same thing WVHillbilly mentioned about the 47% equity and really started to wonder about the way I chose to play it. He ended up having AK.
