So nothing really got there. His small betsizing throughout the hand makes AK and even KQ quite unlikely to me and he looks more like a TT-JJ or even 77-88 type of hand to me. Raising small river bets as a bluff (<= 1/3 pot) is something I found is pretty profitable in 10nlz since they seem to be weighted towards slim value and not very balanced at all. I chose J4s as a bluff since it is one of the worst hands that ever get to this spot. Also, even though I'm blocking flush draws, it is only with the Jd and 4d so I am not blocking too many combos here.

Lastly, I wasn't sure about sizing but figured just shoving would seem the strongest and would be what I'd do with my value hands (I think I would play AA and AK this way I think, not sure about other combos)

I would be interested in your advice, also I'm sorry if I did something wrong as this is my first hand history post.
