Congya Zhang captured the $2,200 Global Poker Championship after overcoming a field of 830 entries.
The tournament generated a $2 million prize pool, with Zhang collecting the $300,000 first-place payout after defeating Sergei Petrushevskii heads-up.
Petrushevskii earned $200,000 for finishing second, while fellow Chinese player Yilu Yuan took home $140,000 in third place.
Zhang began the final day ranked 12th among the 16 remaining players and reached the final table with one of the shorter stacks. Her position improved during the later stages through several double-ups and important eliminations that moved her into contention.
Her route to the heads-up stage included eliminating Adrian State in fifth place, Mengdian Peng in fourth and Yuan in third.
Zhang entered heads-up play against Petrushevskii with an advantage of roughly four-to-one in chips.
The final hand saw Petrushevskii move all-in with pocket fives against Zhang's pocket jacks.
Zhang's jacks remained ahead through the board, securing the Global Poker Championship title and the $300,000 top prize.
