Hero ($375) - tight bit of a nit and folds alot . Plays straight forward

Villain ($450) - 30 asian reg, has work at 8pm, its 6 right now. Been very loose and raising alot and cbetting but knows when to shut down.

Hero has pretty much never won a decent pot from villain. Villain is best player on table and pushing people around.

1 EP ( $150 ) limp, Villain raise to 12 in LP hero calls with A6HH on button, ep calls.

Flop ($38) 6c Qs 9h

ep check , villain bets 20, hero calls thinking has bottom pair + BDFD and villain could have anything here. Ep folds.

Turn ($78) : 10h , villain bets $75, hero tank calls hoping for a heart on the end or a 6 or ace

River ($228) : 4s , villain announces all in ... Hero... Folds? Call with 2nd bottom pair??

what would lead you to believe that V has air here? Do you have any solid physical tells? Verbal all in is usually a sign that the player has it.

Turn bet so big, I'd probably fold there.

As played river is a fold.

Generally a player you identify as the best player at the table, and by definition better than yourself, you should probably avoid in marginal spots. Preflop is okay but would prefer there to be a call or 2 in front of you. Flop call is kinda okay but you could fold here and be happy. Turn needs to be a fold.

I fold turn to a PSB, there's a decent chance your Ace outs are no good as AQ and AA make a lot of sense here for V meaning you have 11 outs, so you're not getting direct odds. That said, you are getting implied odds and if you plan to bluff shove the river if a spade hits you can definitely justify a call on the turn. Against described V though it would be difficult to pull this off so I'd fold turn.

As played on the river, if V views you as tight and straight forward he should know you have a lot of spade flush draws in your calling range on the flop and turn and should not be bluffing the river often enough to justify a call with 4th pair. Fold.
