I got crushed in a hand by a guy who played his JJ like you yesterday. Ironic to read this post today! I RFI 4x in MP w\ 7d7s. Button (a fairly aggressive player), SB and BB call. Flop Jh, 7c, 3h. I C-Bet $30. Button calls and others fold. Turn is 2d. I bet $60. Button calls. Why? I am putting him on a heart draw. River is Jh. Awesome. Assume he hit his flush, but I have a Full House. I bet $100. He goes All-In for $300. I happily call. But unhappily see him roll over quad Jacks.
How might I have played my hand better?
