preflop is good, flop either raise big something like 6 to extract from weaker aces or just call as his small bet very much looks like KK that fears the ace. But I don't think you can just call there b/c you are 5 to the flop. So make it 6. On turn and river looks clear vilain has a little something and want to go to showdown cheaply prob KK, maybe a weak ace but doesn't fit w/ pre flop. I raise turn to 7. River raise is clearly too little prob raise to 7-9 as he seems pretty bad and your line doesn't look that strong he is prob calling there with KK aand A9-
