getting almost 4:1 this is an incredibly easy call.

Bet more on the flop, check behind on the turn. You're only asking about the river because you messed up the other parts of the hand.

Don't check this turn. A club is a bad card, but you're playing way too low of stakes to slow down with such a powerful hand. You are much more likely to allow him to draw out on the river than already being drawn out on here.... especially in a raised pot.

Bet $7 on the turn and if he pushes (for $6 more in this case) call him.

I don't mind the check on the turn because the only real draw on that board on the flop is a flush draw. If you have it anywhere in your notes that this guy chases flushes, I'm checking the turn. Barring that though...I'm probably betting as well. I don't like to pay off flushes at NL25.

If you bet pot on the flop, and pot on the turn, the river play is an easy call of course. As played, it's still an easy call, albeit a crying call. Of course, you are playing 6-max which means K7 is very likely here as well as K5, 68, K, AA(I've seen this passive play with AA alot recently), and a lower set of course. I still think you won this one.
