Not necessarily easy, but as you said, you have 22% equity against his range, so I think it's better to do the old shrug & fold.

Next time,I think this is a perfect example of a spot where pot control would be very helpful, especially since you're OOP so it's harder to keep the pot small. If you really don't see any aggression, then you could go for the raise on the river, but on the turn, like you said, he's all in if he has better and in that spot you're forced to fold.

I'm not very experienced like most on this site but i think check/call would be the best play here OOP. Raising the turn OOP and checking the river looks super weak. If you're going to call an $8 bet, you're better off betting out and folding to a raise. I still think check/call is the best play.

Guljo - I think you are placing far too much emphasis on AK (especially given he is the button and that you block AK). On the other side of the coin I would be a lot more worried about whether he floats your small check raise with QJ (I think there is a chance that he peels this in position with the intention of bluffing many board changing rivers if you check). I think he is calling the turn much much wider than you suggest. He is facing a less than 3x check raise with position. 

I think you should widen his calling range on the turn and re-evaluate. For a start I somewhat doubt he is folding any flush draws getting nearly 3-1 with position on a dynamic board.

Oh I think I probably find a call on the river here, it'd fairly close for me though

you arent even ahead of his turn continuing range unless he cant fold AK/Q hands (and even then, you are only just barely ahead), so I dont like the turn c/r especially since you are OOP and lots of rivers suck for you, as well as the fact you fold your equity when he shoves his better hands (its not much equity, but still).

betting river is better than c/c, because you cant get bluffed, and hes going to call hands like A6 that hes not going to bet. So once you check, it should be to check/fold

If his pushing range on the turn has you beat why xr?  did he have 66?  Is deff a c.f here in your line on river.  ITS one of those Hullmuth spots,, where you misplay the hand but actually lose less than you should of gt wise bc xr the t actually isnt that great.  xc or  L might be better on turn than xr if you want to have some flush draws and big tp's, but its not great and barely gto.  but of course blf ketch is the best line even with your streenghth here. I like a xr on the flop honestly
