J.C. Tran was involved in a three-way hand with Leo Fernandez and Ray Henson. Leo had bet on the flop, turn, and river. Ray let it go by the river, but Tran called Leo's all-in bet after the board came running spades, with the spiking last. Tran turned over pocket sevens for a set, while Leo held 10-2, no spade.
Tran's set was good, but many players at the table seemed confused why he wasn't worried about the fourth spade. Easy. According to Tran, he didn't realize it made the four-flush when he called.
