I hadn't play many hands with this guy at this point, but I did happen to see he made a raise earlier with a weakish top pair hand on the turn and checked river in position vs an MP delay c-bet. I had already pulled up this info when I sat down, but not much else.

This is clearly an optimal bluffing choice, in my mind though this dude seemed quite spastic and likely had Ax a lot which I didn't think he would be folding a whole lot....I meam it is like the worst hand we can ever have and it is fucking perfect to shove so i can't fault shoving I just don't know if it is going to be plus EV in a vacume vs what I am assuming his range is (a lot of Ax and at a small frequency A5s, AJ, 55, though he would likely raise larger on flop or bet turn larger) His turn sizing really makes me want to shove but I just can't find the heart......lol.

Ideas about these spots???
