[Aisthesis]

Well, I honestly don't think it's a sin to lose your stack to KK or QQ here. I agree that the PF play for those hands looks strange, and you win against 55. Of greater concern is indeed J9.

I'm really not enthusiastic about either of your checks. I think it's way better to bet out that flop at around $400 or so and hope you get raised. I mean, while old guy's re-raise was an easy call, you still need to get moving to play for stack when you set if you want sufficient value out of them in a re-raised pot.

Basically, I REALLY dislike the check-call line here, and I also see no reason why villain can't have J9.

Back to as played: I think his range here is 55, possibly QQ (I just can hardly see KK against most players, and QQ is also a fairly likely re-raise) and J9. Your betting here also looks crazily weak. I guess I call, but he's turning over J9 more than I'd like. Any read? As played, I definitely don't think a fold is horrible.
