I think every street is misplayed to be perfectly frank. Don't like 6xing it pre, £7-£9 is plenty. Raise the flop. You have ridic equity against any hand and this equity will be halved on 3/4 turn cards so try and get as much money in now.
As said before bet turn. I'd bet tempted to shove river, he can't ever have QQ or KK I'd imagine so were never losing really.
6x is a fairly standard open in this game, pretty ridic gambley game where the standard open is prob more like 7 - 8x. My reasons for flatting the flop is because the small blind is a massive spaz and I want him to call behind which he basically will be doing such a high amount of the time with complete air. Heads up I am always raising this flop. The turn check is pretty meh but i think i am more likely to get villan to call my river bet light on the river and i do think there are alot of Kx in his range that i am never getting 2 streets of value from, but he will never fold top pair to me as played if he checks river and i bet 3/4 pot.
Basically I agree that my line is pretty horrible here but at the time it made sense to me. With the dynamic of the game the way it was i really just think he is only ever overbetting here with nut like hands, mainly due to the fact that the average standard in this game is pretty bad and most people on the table are not even going to pay attention to the size of the bet and are just going to turbo backflip with any K, being that he is likely to be the only thinking player at the table and being that he is well aware of this does it not just feel like we are basically crushed by his river bet range?
