SH 0,25-0,5 AQ c/r oT

I would say bet calling because hes so tight and nitty. hes easily folding a big part of his range. and the plan for the river I would say depends on the cards. But it is just a matter of calling because AQ is high in your range for calling. and the only note you got is basically saying that he is able to c/r with a lot of good stuff. which only speaks for calling your AQ.

I can't say what good cards is or bad cards on the river that would make you should fold. but thats how I see it.

Pretty Standard check-back and call on most rivers (K rivers make it possiby debateable but even then)

AQ is basically smack in the middle of where we want to be checking back on this turn, it's acutally toward the top of our checking range but tbh I wouldn't even C-Bet AK here, I'm also debating on under-pairs to the board although I suppose they could be a part of our bet/fold range.

I would call river on every card pretty much. The only debateable one is a K as that would hit our x/b range pretty hard and then leave us folding A-Highs on the river but even then I think we have enough bricked A7, A9 and AJ to avoid folding AQ but that would depend on your 3-betting range overall.

I agree to Boomer. The T has hit a lot of hands in his range. T9 JT QT KT AT and he maybe intended to c/c c/r a strong hand, A8 , 66 etc. It's really a pretty easy checkback as you have to call down to a checkraise and a blank river due to so many cards and in a vacuum you always have to ask yourself when betting the turn?

a) can i follow through with another valuebet on the river

The answer here is now. ALmost any River is not good for you to valuebet again

b) is any better hand going to fold

The answer is no - he won't fold any pair and as i said, T has hit his range pretty hard

KQ just got 3 outs against you. J9o shouldnt be in his range preflop so you just need to be concerned about KJ and QJ with some outs against you but preventing a freecard doesnt outweigh the disadvantages.

Actually a king is an absolute blank and i'd pretty easy snapoff a king on a river but certainly fold to J 7 and 9 river and certainly raise Q and A river.

A K's actually not a blank becasue of how hard it hits our checking range

If our opponent bets the river if we're looking to make him indifferent to bluffing on a non-K we'd probably be folding all our K-Highs we check and then we'd look for potentially exploitative additions. A well-playing opponent on a J, 7 or 9 should recognise that Kx and maybe even weak Ax are now bluffing candidates, vs this guy it's possible we can overfold the river because he's probably not thinking on that level and will have a super-heavy river value range but that's dependant on what you've seen so far

On a K however, a LOT of our checking range has just improved to top pair so therefore A-High becomes the worst hand in our range and thus now A-High is the folding candidate

Agreed with all of the above, super-standard checkback from both balanced and exploitative perspective, unless the opponent is super loose-passive.
