While Day 1b of the Monumental Stack has taken over the MGM National Harbor poker room so far today, it's not the only event on the schedule.

The $300 No-Limit Hold'em Double Greenchip Bounty event begins at 3 p.m. local time. This event features a $10,000 guaranteed prize pool.

Players begin with a 25,000 starting stack. Levels are 20 minutes long until Level 10, when they will be extended to 25 minutes. Late registration is available until the start of Level 10. $50 of every buy-in will go towards the bounties.
