As stated, cbet flop is a mistake imo. You honestly just get annihilated EV wise when called, and probably are called a fair bit. Make it A9s and likely better.

This might be a turn to consider x/calling, or at least x/c or x/r, your entire range; depends on what you do with hands like KQo, KJo, KQs-KTs, and TT preflop, but if you're flatting those a sizable percentage and 3betting a more delinearized range then it's especially a good idea.

As played at the river, clear jam.

Preflop seems fine, especially given your choice of sizing.

The flop bet is KIND of close; reasonable continuing hands from villain will include some hands like 77-99, Tx, and BDFD overs like AcJc that are actually pretty stoked to continue on the kinds of cards you're looking to barrel. However, your range should be a fair bit stronger than his given he is in the SB (you should have more T9s/T8s/QTo type of hands), and your barrel cards should push off the other over-cards + bdfd's in his range, so I'm with you. Better hands to check/give up are KQo, AhXh type hands imo.

Turn bet is standard, cards like that are the reason I like the flop bet.

River bet sizing is interesting; if the turn had been 7c and river 3h, I think it would be an excellent spot for your overbet to put hands like 99 in a "ummm wtf spot", since you'd be wanting to barrel hands like J9s on a turn 7. However, given the 3c rolled off, I think your range is a bit too strong and you end up a) restricting yourself from betting AA/KK and b) spending too much on bluffs with your 6c5c type hands to get a favourable return. So I favour a smaller bet here.

Folding here is probably not something you can do without population reads. Go ahead and choose for yourself whether you think anybody has the balls to x/r something like ATs or 88 here, which is kind of what you need. 66, 77, and TT are all reasonable hands for him to show up with here, so if you want to fold then fine, but I probably don't.
