There's only one player left in this tournament with really big hair, so when we see a player with really big hair putting chips in the pot we know it's Alex Jacob. Jacob was all in preflop and called by Lucas Priour. Jacob was drawing with against Priour's pocket eights. An ace but no eight on the flop left Jacob in great shape for a double-up, which he secured when the turn and river came running tens.
Despite that setback, Priour still has 370,000 chips. Jacob now has 150,000.
