KhJh - You played this well imoand I like every street. Don't fold the turn you have likely pretty awesome implied odds here especially with these stack sizes and can expect to win a fairly huge pot quite frequently on the river and get him to call a massive over sized value bet on h rivers with his 2 pair or w/e. Don't raise the flop since he prolly isn't light here often and has at leats an overpair that he isn't folding. It's no fun getting it in this deep with jus 45% equity max and often less when we can maximise our EV vs his range by calling hammering the pot vs his stationy range of hands he ain't ever folding when we make our nizzles. As for your river line just donking huge is likely gonna be best since he'll check back shit like 88 JJ and crap 2 pair a ton being so passive. I'd Jam the rest in on any heart river for sure.

KTo - Don't flat this 3 bet, your bhand can be totally dominated fairly often depending what sorta shit he 3 bets from the sb (i.e lots of broadways as his bluff range = bad) 4 betting can defo be an option here id he's 3 betting like a monkley from the blinds and it appears he is. We block a few of the combos he doesn't fold to a 4 bet like TT AK KK so this is a decent spot to 4 bet him. There is however, no need to 4 bet this big. We can make it like 2.4x or soand expect to fold out the same amount of his range provided he isn't a tard that flats shit like 66 to 4 bets (we obv didn't know he was at the time so w/e) If we do know he likes to flat 4 bets with a ton of his 3 betting range then we just aren't 4 betting as a bluff but wider for value (AQ AJ 99 TT JJ) etc.

Okay so as played on the flop I don't hate firing one here expecting to fold out any AQ AK or other non paired nonsense he decided to flat the 4 bet with. I defo would not barrel the turn or river once called since I expect his range to be mostly stuff like 99 TT JJ QQ+ and doubt he's ever folding it. Wanting to barrel the turn and river is pretty suicidal here and I think you're maybe just being a bit results orientated. Both of these hands are played fairly well imo and should give you info to take good notes on these villains since what they show down in both these spots will help you out a ton vs them in the future in villain #2s case, we aint gonna 4 bet him as a bluff, but town him preflop with a wider value range etc.
