Pre is very close imo. If you have a good player on the button i fold this pre or if you dont play very good post. Since both player check OTF i would cbet since i can easily fold if i get raised.

Turn card is good to barrel again. Since u have nothing OTR and there are lots of draws that missed and its even hard for him to call with 2 low pair i woud bluff in this spot. He never has Q8 or Q5 here so sometimes u can get 2 pair to fold and he will often have a miss FD here imo.

I think he can have Q5 Q8 backdoor straights bottom set even all the time, cause he has 0.5 AF and these guys wouldn't get it in to save their lives. But because we don't have any fdraw and we're at the bottom of our range we should bluff, probably half pot will do.

Some marginal decisions to make, but all in all it looks ok and consistent. I would bluff the river, as played. 

As others have said, preflop isn't automatic, but it's fine to pour on marginal CO opens in Zoom, so yay. The flop is the most interesting spot, I think. When we have the option to take a free card with a few nut outs against two opponents, I generally think that's a good idea. Especially with a fish in the pot. Not that semibluffing a handful of outs is bad as such, it just seems unnecessary here.

I'll explain my thinking:

It's not a spot where we should bet a lot and light. It would be a little sad to bet-fold. Getting called on a drawy board doesn't mean we're playing against capped ranges on the turn. So we really don't have lots of good cards to barrel, when called (and even when we spike gin, there are many redraws to dodge). Sure, we can always try to gun our way out (and as played, I think the river bet is necessary), but a little foresight on the flop can spare us much of that.

With 6 immediate nut outs + two BDs (7-6 and d-d), I would just check back the flop three-way and realize my equity. It's not that I think my draw has lots of value and implied odds when I check (the hearts on board sees to that), it's rather that I don't see much point in semibluffing it 3-way when I can take a free card.

Think blockers are overrated when ranges are wide. Don't think it will make a huge difference whether you bluff this on the river or the same hand with 2 hearts.

Personally I like the flop-bet, turn barrel and would bluff hearts on the river. I think people are overestimating how often you get check-raised here, when they want to check back. It's way more likely that you get bet into big on brick turns, which will be a very marginal spot and there are a bunch of turns, you will have to fold also, so checking back to ensure that you see one more card at the cost of seeing two quite frequently doesn't make any sense to me. 

I'f they only check-raise strong hands and no bluffs, you probably aren't getting check-raised more than 10-20%. If they check-raise some bluffs also, you probably have enough equity to jam over it.

Thanks!

Ofc it matters, if the guy c/c everything except QQ or 88 and you hold both the inner wrap and the nfdraw, then the combos of hands he calls both flop and turn are either Q*** with something that may have made 2p on river and probably not folding or a middle wrap. Mr Phil said you should be less inclined to bluff on river when you have all the missed draws.

Yeah he needs to bluff here and i think he shouldn't be very happy about getting himself in this situation by betting flop, but if he had inside wrap or gutter + fdraw, then flop and turn cbet would be standard but i think less good on river. Maybe a better cbet if flop was Q84hh
