Michael Moncek bet 3,500 on the flop and JC Tran, sitting on his right, called.
Both players checked the turn to see the river.
Tran led for 10,000 and Moncek quickly called.
Tran revealed pocket jacks and Moneck mucked.
Moncek holds one WSOP bracelet while Tran has two and they are likely to clash a lot today sitting right next to each other.
