Hello everyone, I frequently feel a little lost on how to approach 4bet pots with low SPRs. I ended up folding the river because I was having trouble thinking of hands that I beat. I would love to hear your thoughts on the line I took. Thanks for the input!

Ignition 10 NL, 8 Players, My first round on this table so no reads on villains. Hero is on the button.

In the moment I felt like the J was a bad card for me given that JJ were the main hands I was beating before the river. Was this a nitty fold?

Seems fine to me, if HJ is bluffing congrats to them and you don't beat value.

Agree with @boulgakov. Fold is fine.

In a 4-bet pot, looks fine. Nh.

Thanks for the responses. It's good to get some confirmation.

In retrospect, I was really fixated on vil's value hands, but not thinking about how HJ should not be bluffing much here. I show up on the river with all sorts of hands that are happy to stack off at SPR .5.

Absent a strong read on vil this does seem to be a comfortable fold.
