Splashy sunday afternoon $1-3 game, finally on the right table but running bad and in for a few buys,

Hero CO: is 34 year old grinder , in for 3 buy ins which = $920 but grinded it back to ($800), image is LAG, maybe a bit too lag for some of these player types,

Villian BB : ($1400) middle aged chinese guy, generally passive player, likes to go to rivers with Top pair + type hands, doesnt like folding draws, seen him open check made straight on a 4 straight board oop into preflop aggressor when action went x,c,x,c, x, x, Have not seen any relative bluffs from him in about 2 hours

Hero is dealt AK , make it $15 to go , 5 callers,

Flop ($75) 56J
Villian donks $50 , folds around, Hero calls ,

Turn ( $175 ) 9
Villian leads $100 , Hero calls ,

River ($375) K
Villian checks , Hero ?

Some thoughts :
- flop & turn , raise the flop or turn and try to use my range advantage ?this specific player I doubt he bets less than Jx and not folding to a raise ,,,,not sure I have much fold equity against said player type, what do you think ? is this a spot to just flat and play smaller pot while trying to realize my equity ?
- river, checkback or go for value ? sizing if you lead ? what situations would you consider checking back ?

thanks in advance for comments,

B/F $215. Might have raised flop.

Flop call seems fine. I don't think you're ever getting him to fold a Jack here and I'm not sure if AK is specifically the flush draw to build a pot with.

River seems like a clear B/F. Previous poster suggested $215 which is right in line with that I think AJ, QJ, JT might pay to see since there is a missed flush draw out there.

Flop fine.

His turn lead is TPTK or two pair.

I'm checking behind otr and expecting to see AJ/56s/QJs/KJ/J9s here. I think H is 50/50 against V's range. So I check back to manage variance. A bet targets AJ for value and maybe 56s for FE. He's folding QJ and beating H with the rest of the range. I think it's a coin flip.

I really want to bet the river, but I feel like I've played this hand 100 times, and everytime i bet the river I get tank called by 2p+ and the guy says "I was worried you had KK." I'm sure there are player types where a bet here is right, but against this guy check back seems good.

Yeah $215 would be nice value bet, merits for rasing flop for sure ,

Why do you think AK is not the specific flush draw wanting to build pot ? I agree with its a clear b/f line probably ,

Yeah agree with your points , but still itching to go for a bet fold line , there's no way in 100 years he would ever check raise as a bluff so I prefer the bet fold line ,

No doubt this hand is familiar isn't it , crazy, I totally see your point here and checking back would be good to limit the variance

Fortunately, V misplayed the Turn badly with a bet size that priced in nearly your entire range. nh

I often like to raise flop against donk bets if I have a hand with any kind of reasonable equity, however, given that it's 6 ways, I think his donking range will be a bit stronger so flat is very reasonable.

I was going to suggest $150 on the river, I like your sizing. I don't think checking back is crazy though. Does he flat 56o pre? If it's just 56s, then I definitely like a bet.

Raise worse fds and call nutted fds. Especially if deep.
We don't wanna fold out straightdraws that we beat (and that could bluff on flushcards) or lower fds nor do we wanna get it in here.
SPR is essential with these hands.

Because villain cannot have the second nut flush draw.
