straight in the middle with the lot.
This is exactly how i play over pairs and i push back over your bet anyway so if you have the set im paying up no problems for the amount of times my overpair doesnt walk into a better hand.
Push all the time.
If he doesnt call its an ok pot anyway.
If he happens to have two club overcards (looks unlikely) ill take my chances with the set too.
Did you win or did he manage to suck out?
