Top Pair Weak Kicker from the blind against a LPP

Here is the situation from this hand. I am curious mainly about my flop raise and my turn bet. MP1 is a 49.5/0/0.65 over 85 hands.

Final Pot: 6.50 BB

Here is my reasoning for my plays: After his flop bet, I figured he could have almost anything in his hand, from another ace (chances are it will be a better ace), Or a good Jack like KJ, QJ, or even TJ. He may have been on a flush draw, but I haven't seen him semi-bluff any flush draws over this small sample size. I raised the flop to get it heads up against somebody that could have almost anything, I didn't really want UTG+1 tagging along.

After he didn't reraise the flop, I figured his hand wasn't that good, so I went ahead bet the turn, hoping for a fold due to my flop check-raise, but not terribly unhappy with a call. On the river, I assumed I was beat, but I honestly did not know. Am I ahead of his range here?

The way you played it a river bet is for value.
