5/10/20button straddle at the Wynn, I start the hand with 11k and villian has around 35k.
Chinese in late 20s/early 30s maybe?
This sounds like Frank (maybe George, but pretty sure it's frank cos he didn't bet $2500)
He's sticky pre-flop with deep stacks like this and whereas he's defo capable of bluffing (he can go a little crazy sometimes) exactly what is he bluffing with,

,

,

maybe, a naked 7? His Ax combo's are pretty thin, there is only 1 AJ suited but he might call AJo sometimes IP with these stacks + he's very capable of making thin(ish) value bets. Like he's got it in him to float the naked

and vallue bet now etc (not saying that's what he's doing) I'd be quite surprised if he checked a flush back but it's not IMPOSSIBLE.
I think I'd fold cos whereas there aren't a huge amount of value combos jumping out at me the lack of flop calls that are legit bluffs now (I mean 7x and a worse J maybe trying to make you fold this hand or QQ IDK) combined with his ability to value bet quite well + I don't think we can beat any value bets now. I think if I could beat just one value bet I'd talk myself into calling here but for that reason it's defo a fold for me.
