Chris J raised to 4.5K from under the gun and it folded around to Paco in the big blind. Paco moved all-in for 8.3K total and Chris called with Ac10c. Paco showed pocket jacks. The flop was Qc-Js-2h and Chris needed a king to make a straight and take the pot. The turn was the 7d and the river came 4c to give Paco the pot with his set of jacks. He now has around 18K while Chris sits with 15K or so.
