In my opinion you want to be c betting this flop when you've been the aggressor pre. There are a few reasons for this. a) If villain has two hearts, say KQ, AK, AQ etc he is most likely going to check behind to get a free card, so betting is good to charge draws. Especially even if he has like 99s or 88s. Also if he decides to raise flop you can even fold depending if you think he is ever raising fd, though you probably gii. b) if you think villain has JJ-KK in his range bet flop for value which would leave an all in bet for the turn if it blanks. There's no point in playing your hand deceptively when there is so much value in the pot as it is. Even if your bet on the flop takes it down you shouldn't be extremely upset. c) This flop, for me at least, would be a flop id cbet with AK and AQ a lot of the time as well (which is a decent part of out range). So by checking our value hands on the flop and cbetting others its unbalancing our range. I think this would be a flop to c bet like 100% of our range here, even all sets.
 
The river decision is probably check fold, our range ott looks pretty confusing actually so it wouldnt make sense to bet on the river for him without a hand. Quite often he can turn up with something like J10 maybe or flushes, though definitely 98 is right at the bottom of his range which is unlucky for you.

Hope this helped :)

shove river with AA is nonsense :worse never call,with KK-JJ he will be happy to check back.

and one more think i dont see many bluff in his range and i m not really scare about he bluff me on river->check/fold is best.

Probably 4b a bit bigger - if he's iso'ing a big hand hes not folding with position and we are a bit deeper, so i would probably make it like 50-55 here (little thing)

As played betting the flop is mandatory here we have got to protect on this draw heavy board that alot of his hands that called a 3b will hit - we want to try get the money in now before any horror turn cards

I would have shoved the turn (having bet flop) but as played I think again you need to betting here to protect your hand and get value from all the hands you beat - (which is a heck of a lot)

River is a pretty horrible card - im checking to check fold, he is never betting worse and everything we beat checks back :)

Bet-calling the flop seems best when there's already 45BB in the pot. You lose to TT/77/66/maybe 98s, and he shouldn't have T7/T6 etc. You beat all of his FDs, combo draws, overpairs, AT.

His play was awful, btw.
Calling 22.5BB with 98s is bad, the flop xb is bad, the rest is fine.

I don't understand the river donk jam. Sure he can call with a few aces thinking it's a split but he also has a whole bunch of tens and also sevens in his range. At least in the live games I play in people will be opening and calling a 3bet IP with a bunch of suited connectors and even gappers. Could even have hands like KTo, QTo and JTo. I'd make the 3bet bigger pre and then def bet the flop.
