New to pot limit, did I play this hand correctly

[Nukid]

Playing pot limit ($1/$2 blinds) for one of the first times, I ended up in a three handed game with two very loose aggressive players. In this hand, the button straddled to $4, and i was the small blind. I had $168, the big blind had around $100, and the straddler had around $800. I had AhKh, and raised it 8$. The big blind reraised me $12. The button and I both called.
The flop was KdKsQd. I checked, the big blind checked, and the button bet $40. I called and the button folded.
the turn was a 7d, I checked and the button bet $80. I called.
River was a Qs. I bet out my remaining $24 and the button called.

I'm going all in on the turn seeing how you're almost all in anyway, I think I'm check-raising the turn all in. I might have done it on the flop, but you have the other player in there so you tried to keep him around, once he's out though, time to put it all in the middle.

Check-raise all-in on the flop.
