"Passive" isn't the word for it...

[MasterShakes]

...there simply must be a stronger word than "passive" for this kind of play. I know there must be fear of a 4 or a flush, but my god... it's the best hand in the game.

What makes you think that you dont have a valuebet on the river ?

[MasterShakes]

What scared me was the willingness to bet into me on the turn and then for both players to call my raise. I know online reads are often worthless, but there was also hesitation from both of them when they checked to me. When the flush, straight and overcard all hit clearly on the river with two people who appeared to be drawing, I think I'm going to be check-raised.

Makes sense I guess.
The turn cold-call followed by a flush card isn´t great either.

You've gotta thank the guy for the load of cash he saved you. Between the two of you the betting should have been capped PF and after the flop...at least.
