There is an interesting story brewing here in Day 2 of the All-Stars for Starlight event, as the current chip leader Ramnik Singh was nearly blinded out today, as he apparently slept through his alarm and only showed up at hand-for-hand, 6 levels into the day. His stack was blinded down from 149,000 to just 26,000 before he finally showed up. He moved all-in twice during hand-for-hand, winning in both cases, and has since grown his stack to an impressive 950,000 total.
Other current big stacks include Kosta Papa (roughly 900,000) and Francis L (roughly 820,000).
