Paradise $50 NL. Table is normal for Paradise which is to say full of idiots.

JJ in MP and raise it up to 5x, get 2 callers, the c/o and the button.

Pot about $8. Flop [6s][5c]. I bet $7. 1 caller. No read but he covers my full stack.

Turn . No spades in my hand. I start looking around for hands that I beat at this point. I find TT and 99. All sorts of flush and straight draws got there, plus of course sets and better overpairs are possible. Some of these idiots really love to slowplay big hands. I think for a while and check, he thinks a few seconds and bets half pot, I fold.

Weak or acceptable?

Good fold in my book. You can only beat a bluff and he has position on you. What sort of river card do you want to see?
