Comment on Phil Ivey's play: one hand from today's WSOP

[Steve Chase]

Here is what I got from cardplayer.com for one hand Phil Ivey played today at WSOP. Any comment on Ivey's play here?
What will you guess as CK Hua's hand?
Lower pair? AK, AJ, AT?

"CK Hua makes it $22,000 to go. It's called by the player in seat #3 and Phil Ivey. The flop comes Qh-7s-5d. Hua bets out $55,000, and Ivey is the only caller. The turn is the 3d. Hua bets out $90,000 this time and Ivey calls again. The river is 4s. Both players check. Ivey shows Q-J. Hua mucks, and Ivey wins a $300,000+ pot."
