We've seen it before in pot-limit omaha tournaments, now it's come to no-limit hold'em. It's the triple chance format, where players are given one-third of their stack straight away and two "buttons" that that they can redeem for additional chips at any time in the first few levels of a tournament. Some players will redeem those buttons right away; some will use them as a save to overcome bad beats; and some will wait until the end of the redemption period to acquire their extra chips.
There are no additional fees for these rebuy chips. One buy-in gets you all the chips whenever you want them. Players will start redeeming them at noon local time, in ten minutes. We'll see you then.
