Preflop is standard i guess. However after that I don't like my overall line, I'll explain why I played that way, but please make any comment about other better or at least possible lines 
Standard dream flop for a pp in position. The guy cbets 75%+, so I decided a raise was out of the question since I would scare away broadways and sometimes overpairs. However I now don't like my call because a lot of cards may kill the action. I don't really know here. I decided to call to let him 2nd barrel bluff OOP, 2nd barrel for value w/ overpairs, or let him hit his facecard with his broadway.
I don't like the turn card, except it now makes my hand stronger than 99 and 88. A five is definitively in my preflop and flop calling range with a lot of SC (I think he knows that since we have a good amount of hands together). Here again I don't like my call since a call, call, raise line shows a lot of strengh to value on an overpair (because this is the only category of hands I can value against). However I did not like the raise here because the five is extremely present in my range, and I don't want to scare him, nor prevent him from 3rd barrel.
The river card is an action killer (at least I though so at that time). I had no real clue about how to extract value here as he checks. I though that a "small" bet (between 1/3 and 2/3pot) was showing too much strengh as I will often do so with a five, seven, or a fullhouse/quads to let him call. I couldn't see him call an obvious valuebet with his hand. I decided to potsize allin here to increase the amount of bluffs he will perceive in my range.
I think he made quite an ugly call here, and consider the hand as if he had fold (so I missed value). I'm really wondering how I could have extracted more value here. Maybe shoving "potsize style" on the turn for maximum aggression into his good made hand?
He perceive me as a very aggressive player, depending on his degree of objectiveness to him I am either a LAG or a lucky maniac, that's also why I chose the allin river.
