San Manuel Casino, 2-5 NL, $150 stack, everyone has me covered, 9-handed, no reads as it is my first hand. Prior four pots were raised 15-20, that I did see. Some pros, some Joes, villain is right behind me and is unknown. I sit down UTG, no post required, look down at :Qh: :Qd: and flat, expecting a raise so I can go all in. Villain flats, everyone else folds to my surprise.

So I am heads up OOP and don't know anything. Pot is 5+5+5 from the BB, me, and villain, SB folded his 2 and the rake is 4 so effective pot is 13.

Board comes J-8-4 rainbow. I donk with 15 and villain makes it 40. BB folds and I conclude, perhaps erroneously, I am up against the following range: AA, KK, JJ, 88, 44, J8s, J8o, T9s, T9o, AJ, KJ, and who knows. "Feels" like I should shove but my gut says "way ahead or way behind", not sure I want to shove the first hand.

What do you guys think?
