April 2019, he left PokerStars after 9 years with the company. It was a good run for him though I'm not sure what he's up to these days though he may have some involvement with GG Poker. Perhaps someone here who follows these things more closely than I do might know.
Or GGPoker, especially in light of PokerStars recently departing from China and Taiwan most notably. That's a HUGE player database gone, and those players will definitely take their play over to GGPoker, or some other site on that skin (Natural8 perhaps).
