Turn does change things now we chop vs any Ax
River I think mixing bet and check is good pretty much never x/f we are looking to bluffcatch vs bricked draws you can even pull the x/r trying to make Ax fold as we are the ones with AK,KK,AA in the range. 4x hands are not much of a concern

You opened MP and yet CO calls... You must be careful here. BB's range is looser

Flop I wouldn't bet here. We're oop versus a strong range (CO). I don't expect a K to call and there is no worse A in CO's range. I would bet my best A (AK AQ AJ) and some draws like gutshot.

Turn we chop against every Ace. Not sure sf betting is the best option

River we're overplaying our hand. We should X here. I can't see the value

I suppose vilain in CO in a NL2 reg... If vilain is a calling station then it's a different story

I feel uneasy about this play. I think we should either check at some point or actually just shove river to fold out an Ax sometimes, assuming villain is capped to Ax. Advocating a check is probably safer.

villain can have a few worse Ax,

So only A2, A3, A5, A6 while better Ax are A8, A9, AT, AJ, AQ and AK.
Beside that, I think you should bet smaller OTF and size up on the turn, I would bet 1/3 and 1/2

Again brick so same bet, although looking back I don't know if leading is good since we're probably only getting called by better?

In this case I open up my HUD and look up for clues whether villain is capable of bet when we don't triple. If he does I check and bluffcatch, if he doesn't I bet and try to get a call
