Is that a good play? I've been having questions on when to slowdown with my overcards. On this hand when I checked the turn the button had his autofold/check button hit as he checked immediately. I checked to him on the river planning to fold if the big blind called and raise if he folded. Is this good thinking or should I have just called?

Thanks
