bluff on river?

Preflop is loose to call.
Xf river.

I don't think it is too loose. It is a call in w34z3l's ranges and in Snowie ranges and imo calling should be fine.
Your A high might be the best hand and I'm not sure if villain is going to fold any pocket pair or Jx on this board if you bluff. You can try but I would say you are not making huge amounts of profit by bluffing there

In general, we should make a river probe with every bluff because people will fold in ~60% of cases. In this particular hand our A-high might be the best hand, so I don't mind check/folding the river. Not sure if we can check/call (bluffcatch) on these stakes, supose not. However, since J came OTR, I do believe we have a fold equity vs TT-55, 33-22 and vs AQ, which beats us, we definitelly have a fold equity. From my experience, I would say that betting this spot would be more profitable than check/folding, even though I don't expect to face a bet very often. To make before-mentioned hands to fold, I think we should use a size of ~3/4.
