If you're planning to play the Colossus or any of the other low buy-in hold'em events at the 2016 World Series of Poker this year, you should be ready to take an aggressive stance early on.
Last year, the starting stacks for most of the events with buy-ins of $1,000 or less were increased to 5,000 chips, with $1,500 events getting stacks of 7,500. That led to some longer pre-bubble play, as structures hadn't been adjusted to the same degree as the stacks.
For 2016, the WSOP has stayed with the 5,000-chip starting stack for the $565 Colossus (Event #2), the $565 Pot-Limit Omaha (Event #12), and the $888 Crazy Eights (Event #54), as well as for the several $1,000 events and the $565 Casino Employees (Event #1).
