I guess we have to take heros perceived range more into acoount here. So two important facts:
- Hero and Villain will have a very low % of bluffs in theire range given the runout.
- One player is AI so we will definetly have a SD

1) I doubt it. Hero shouldnt float two many random Ax hands OTF and OTT with one player behind that is super shallow. Its also a SRP and hero shouldnt have any strong Ax in his range. Therefore i perceive heros range as not too weak, i doubt that he will bluff/valuebet thin on the A anyways. So i would expect Villain to move on here with most strong hands.

2) Villain seems unknown, so vs a random player i would assume maybe. But given the low % of bluffs hero perceives, i still would prefer a smaller sizing. Its also hard to fold if we bet 50% and get shoved.

3) I doubt a bluff at all here. As said: there is not too many bluffs in both ranges and there will be a SD anyways. Ppl. tend to bluff less in this spot. That should also be the case because its a 1card straight on board and a pair that Villain cant credibly repp.
So B/F 1/3 seems solid to me.

4) Didnt do the math, but i guess getting called 85% of the time for one third is better than getting 10% called for pot. Esp. when the risk is high that we jam into a stronger hand.

I would just bet river very small and fold to a raise. Don’t think people bluff ever really with a player all in. I might go as small as 20-25%. Whatever sizing I think can get called by a weak weak hand.

fold pre. am i missing something this hand just loses money
