A KK hand, I might be rusty (6 max)

[jhall23]

Alright this seems pretty simple but I need to get the rust off my game and make sure I am still thinking about things good in the heat of the moment.

So I put villian on a pretty wide range: set, two-pair, draw (possibly big combo), air, maybe a straight. Couldn't see any value in pushing the flop since a lot of the hands he could have have better equity when seeing two cards and would gladly call and only Air will fold.

What I decided to do was to call and then push on a safe turn. Only problem was that I am not sure what exactly makes a safe turn on this board. Is everyone content to consider any non-heart turn safe and just be willing to pay off if they hit some straight?

Anyway, turn was the Q[img]/images/graemlins/heart.gif[/img]. Check/fold yes?
