Carlos Chang raised to 8,000 and was called by Shawn Buchanan from his big blind.
After both players checked the flop and Buchanan checked again on the turn, Chang tossed out 8,000 and got a check-fold from Buchanan.
After Franco Spitale moved all in from early position, a middle-position player with a larger chipstack moved all in behind, which got folds from the remaining players.
The flop was a good one for Spitale, and the runout secured his double-up.
Mike Parekh moved all in and was called.
Parekh was behind and saw that he would need to hit an eight or have a very specific runout to stay alive. He got the perfect runout on the board, turning the nutflush to stay alive on Day 1a.
After Ryan Riess shoved his last 30,000 into the middle, action folded around to Christopher Fisher on the button, he three-bet shoved and the remaining players got out of the way.

Maria Konnikova raised it to 6,000 from the button and the big-blind player called. After the big-blind player checked the flop Maria continued for 7,000, which resulted in a check-fold from her opponent.
A short-stacked Jeff Siegal moved remaining chips into the middle and was called by the big-blind player who was sitting on a sizable chipstack.
The board ran out , and Siegal's ace-high was good enough to secure his double-up and send him some much-needed chips.
