With 9.7k hands, what is villain likely to think of you? Ie is he a trappy player and sees you as someone he can trap?

You do have some showdown value versus him but tbh I think you are better off shoving the river depending on the answer to the above.

This is where reads are really important and with 9.7k hands, you should have a good idea about his tendencies.

this board hits him more than you, i would float in case that you have exact read that he gives up bunch ott

We dont have any showdown value. We are at the absolute bottom of our range. We are uncapped and he is capped. Yes we need to bluff this river.

I think it's somewhat close because it's hard to name many hands you can successfully bluff against but overall I agree with the fact that we're uncapped while the villain most certainly is so bluffing is probably the way to go.

Not really keen on the float SB vs BTN when he has a ton of Ax in his range, maybe it's ok if we have backdoor diamonds but I would just fold the flop here.

As played I'm definitely bluffing the river to try and get him off a weak ace. The jack showdown value is meaningless really.
