What Just Happened?

Hand relayed courtesy of Kenna James.

Action started when Pierre Calamusa shoved all in from under-the-gun for his last 16,000. Donovan Zachary, in middle position, had looked down at his phone and didn't notice the all-in shove, so he tried to make what he thought was a standard raise and instead ended up having to call Calamusa's shove.

The player in the cutoff then shoved all in for 45,000, which was then called by Darren Colbourne on the button. When action got to Joao Manana in the big blind, he then shoved all in for 150,000, which was then called by Zachary, who had a smaller stack than Manana. With so much preflop all in action, Colbourne then decided to muck his hand, which he said was pocket tens. The four players then tabled their hands.

The board ran out , which gave Calamusa a full quadruple-up, eliminated the middle position player, left Colbourne shaking his head, and Zachary and Manana chopping the side pot.
