It's not WSOP, it's just some small live Everest Poker tournament. I did not scroll down far enough to see the bottom of the picture.

The board looks like 6d 8d 2h Ah and Kh. Most likely the winner went all-in with ace and off suit Jack and made top pair on the turn with the better kicker. His opponent probably called the last hand with an ace and low kicker, perhaps off suit, or perhaps a low pair. This guy is mostly like not a pro. Just some dude who won an Everest qualifier. So there could be an interesting back story. I hope that helps.
