An interesting topic came up on the PokerStars live stream, which you can watch here, with commentator Joe Stapleton asking Maria Ho which player she thought studies the most.
"Davies has to be pretty well-studied," said Ho. "Lonis tweets that he's all exploitative and not a really a studier. And Sean [Winter] - I don't wanna assume, but I don' thtink he's the type that's poring over the solvers."
"But if you think about the people Davies runs with, Jason Koon and the like. Those people are obviously in the lab. And Mokri's a sicko, we know his online results. The online fields are very tough, so you wanna be doing some solver-approved stuff in those streets."
