There is one specific time where a poker pro did this. It was Gus Hansen, who is known for an ultra-aggressive style to begin with, and it was under specific circumstances where he had to win the table or be eliminated. If you break down the factors involved, it wasn’t as crazy as it looked. But was still damn crazy.

Once. That happened once where a number of things lined up perfectly. I would be very surprised if you found another instance of a pro player doing this ever.
