BB checks, Hero bets $0.81, BB folds

BB had rarely defended. When he led out, I thought this meant a big hand. A better king or as strong as 55 or 88. I block TPTK+flush draw, and didn't think he'd donk out without Adxd without a pair, as he'd get raised fairly often, then have to call and check turn. I hadn't been double-barreling much that session so if I had 7s9s here, there was a good chance he could just call my c-bet and then get a free card with his draws when I check behind turn.

I can't move him off his hand on the flop so I just call. I think I can bluff out these hands on any diamond turn + any river that doesn't pair the board on the turn. He donks again, I raise as I can represent Ad9d+, or any Kd + high diamond. When he flats the turn, I think he's capped to stubborn TPTK or sets and flushes would 3bet the turn.

So my plan is to follow through by betting $0.81 on any non-board pairing river.

I actually get there on the river, value bet the same amount, he folds.

Does the line check out? Or do you think I would get snapped off on a non-diamond river?

Bet smaller on river for about 1/3 pot.
Widens his calling range. You are almost never being called by worse, with exception to KQd on the river.

Makes 0 sense to bet that large, if he jams river you are just crying inside

I didn't want him to call as he and the rest of the table would see what I'd raised him on the turn with, so I bet large. He'd also lead out with the Ad a lot as I'd just check behind something like Qd10d of diamonds. I also made up for any lost value by going on a tear the next 3-4 obits.

Just fold turn. On the flop I would expect him to have every possible pair in his range + FD's and SD's + sets. on the turn a lot of the draws get there and therefore I would just fold. You lose to flushes and sets and 2 pairs. If he is semibluffing with a hand like a pair of 5,6,8's with Ad you have a lot of reversed implied odds.

Btw, bad idea to try to bluff people off sets at 2NL.

I think the value of getting a call from a worse hand way outweighs the value loss of giving up info. Who knows if others were actually paying attention or even would know how to respond to that info if they were paying attention.

I agree hed lead often with his Ad, so you wont value own yourself too often with a big bet. The only other value i see in betting bigger is to induce a bluff catch, but i dont think that would work too often here. Id bet smaller to get better value from villians calling range.

Lost value is lost value, future hands have no impact.

Your job is to get value. That reasoning makes no sense.

If they see you 3 bet with K10, exploit that and play aggressive with your strong hands. Additionally, don't raise with K10 if you aren't going for value with it.
