If you raise someone, you always have to have a plan if they call or reraise. if your trying to "see where your at" with a raise, then you have to have a plan once you see. if hes gonna bet that small (turn), i may just go into check call mode. Your limp is creating problems now tho, and if you arent comfortable with post flop play like this, then i suggest you start raising 100% of the time. I think your ahead here enough to call to the river. His range is pretty big.
