William Kassouf notoriously dominated the headlines during the 2016 World Series of Poker Main Event with his table talk.
In one big televised hand broadcast on ESPN, he got Stacy Matuson to lay down pocket queens on a ten-high board while only holding nine-high himself. After the hand, he shouted "nine high like a boss," which instantly became a catch phrase among many poker players.
Fast forward to 2017 when on Jan. 11 Matuson publicly challenge Kassouf via Instagram to a heads-up match during the 888Live at King's Casino Rozvadov.
