Maria Ho raised to 9,500 from under the gun and the cutoff asked her for the chip count. "19,500," Ho said. The cutoff then raised to exactly that and behind him the button moved all in. Ho snap called and the cutoff did so as well.
The board saw the best hand pre flop win and Maria Ho counted again, it was in fact 18,600. The button was covered by the other player and has hit the rail.
