First off, I don't mind the limp behind, but I would much rather be raising J9s on the button, especially when there is a poster. You will be taking down dead money most of the time and you set yourself to control a bigger pot in position.

I don't really understand why you raise the flop, and also so big. If you are going to raise, I would have made it .75 or so.

Why aren't you betting the turn? There are plenty of draws that you can be charging and you will definitely be getting called by worse a lot of the time.

Edit: Stacks beat me to it.
