My image was very tight. I hadn't played a hand for 1.5 hours after a tripled up with top set.

Villian was kinda spewy with min-raising and insta-donk-min-betting. I figure he's donk so can I Vbet this river? I didn't due to the pot-to-stack ratio factor, and a standard bet wud be a big chunk of my stack.

Is my line throughout the hand ok? Flop I don't want to be c/r'sed off a good SD hand, and turn I figured raising is pretty bad.

I think check on the river is fine, but don't understand why you didn't bet the flop...

Reverse for me check flop is fine checking river is criminal

I have lots of showdown value that can't stand a check-raise. I don't think many jacks and c/r'ing but QT is the only hand we are ahead that might bluff us off.

Also, how much would you bet the river? Why and how would you respond to a c/r?

Oops, just re-read hand, was thinking you checked to him...

I see what you mean about showdown value, it's a pretty safe flop to check on. As long as you bet flops like this a certain percentage of the time. If you end up showing down the AJ you're going to lose credibility on your C-bets when you flop air...

On the basis of his river check he can't really be trapping here, he'd lead out 99% of the time with anything that had you beat pretty much. Unless he's playing K rag scared or something, you probs have him crushed.

I like a 3k value bet on this river...
