We found Dong Guo in the big blind facing a four-bet to 258,000 from Matthew Sedgeman on the button. Guo had made it 127,000, and he announced a "raise to 120,000."
The floor was called since there was far more than 120,000 in on the last raise.
"Ohhh," Guo said with a groan. "Dammit..."
The ruling was that Guo had to make the minimum raise, and Sedgeman called the 131,000 more, seeing a flop. Guo made sure to do the mental math out loud about the size of the pot this time, ensuring a correct bet amount of 355,000. Sedgeman moved all in after getting a count, and Guo snap-called.
"You have aces, right?" Sedgeman asked.
Sedgeman was on the draw, but it was Guo completing a "flush draw" when the final two cards came and . Sedgeman took the unfortunate turn of events with a smile, shaking Guo's hand.
After the pot, Guo explained that the mistake was due to the way his native language works, in which numbers are said a different way than English.
