Gaelle Baumann had opened from middle position and Andrei Konopelko had defended the big blind, creating a pot of 6,000 chips.
Konopelko then check-called Baumann's 4,800-chip bet on the 9♦4♦6♥ flop before both players checked the A♠ turn.
The 3♦ river was also knuckled by both players, and Andrei Konopelko showed A♣K♦ for top pair, much to the surprise of Baumann.
She took a few more looks at her cards before throwing them to the muck, awarding the pot to Konopelko.
