Reads: Villian is really lose with flops seen at 56% over 115hands. He is also really aggressive and will bet whenever he thinks he has a slight advantage. He's also been caught bluffing several times so he is a bit tricky.

I've been playing fairly tight passive with several explosions of aggressiveness mixed in. My preflop raises have been getting some respect and have been taking down the blinds.

Villian calls 14.95 (All-In).

My reasoning behind putting him all in is that Villian is probably bluffing or has a middle pair at best. While a set of 5's or 2's is possible he probably would have slowed down off the flop and not over bet the pot. If he had 1010-AA he probably would have reraised preflop hoping for a push or to get his stack in then.

The push I think was a good play to a)shut him down and take the pot b) stack him if one of my 14 outs hit on the turn or river.

So, is this a good play or should I have picked a better spot to try and take Villian's stack?
