Pacohontas

In a multi-way limped pot a bunch of players saw a flop of Jh-9d-6h. Paco (pictured) bet out 600 and it folded around to Patrick K, who called. Paco, thinking everyone had folded , flashed the Ks. What do you think Paco had?

The turn was the 5d and Paco bet 600 again, which Patrick check called. Both checked when 8h fell on the river. Patrick had Ah2h and Paco held…KsQd. Good try Paco, good try.
