Like the line, river just x/f, so many hands beat us while we hardly beat anything, like you said AT probably checks behind. Even if he bets AT we still have to fold because he'll have so many 2pairs, even KTs got there

I think x/f is fine vs a tight player but you need to be careful because against some of the looser players betting river might be best since they'll call down all TP which might include all aces and they might bet all aces as well.

If we assume he's not vbetting worse then you're bluffcatching and he needs to be bluffing for you to call. On this type of runout it's hard for him to have lots of bluffs unless he's turning pairs like KQ QT maybe JT into bluffs. I don't think your average tight 10NL player does that so folding it probably best when he bets.

I have a backlog of weird shit people show up with in these spots so I think I check call river. AJ AQ likely lets us know before the river that they are there, as does A9 99 etc. Maybe QJ plays this way. Not having a history on the player makes it murky.

At these stakes check folding is fine. Players aren't putting three streets of money in with a worse hand often enough.

If villain is tight then maybe check calling the turn is an idea. He shouldn't have too many worse Ax combos in his range versus an UTG open, and there's not many draws.

I'm with @Komododragonjesus on this one. While by default I'd just go for three barrels at this limit I'm fine with check/folding the river if your opponent is very tight.

Thanks for responses!

I feel people have a tendency to comment on the best play in a bad situation rather than pinpointing the best line overall.

Turn card is bad, and while we should value-bet again the sizing doesn't make sense. We should be betting $0.70-$0.80 and leaving ourselves with the option to underbet the river. Other option is of course to check-turn which would be reasonable.
