It's essential in live poker not to give away any tells. Hats, caps, hoodies and sunglasses are items that many poker players use to prevent their opponents from seeing facial expressions. However, there might not be any need for these stuff in the future...
Jack Berdy, a doctor from New York, has just introduced "Pokertox," a program of Botox and facial fillers designed to help poker players hide any sign of facial emotion.
"Some people might get a card they like or don't like and raise their eyebrows," Berdy told The Huffington Post. "If that's the common reaction, we can put Botox in certain areas to minimise them."
The new method can also be used to bluff...
"We can also put Botox in areas to make it look like the player has a 'tell' they really don't have," he said.
