With players standing to depart the Brasilia Room every few minutes, it stands to reason that a few big stacks have emerged. We've spotted a couple of high rollers who have both moved over the 50,000 plateau midway through the first day of play.
William Reynolds, who captured the PokerStars Caribbean Adventure's High Roller event in 2010, has built his stack to 57,500, and he will be searching for his first major victory since that six-figure score on the seashore.
Czech pro Vojtech Ruzicka has also been active on Day 1, and the winner of the most recent EPT Deauville High Roller event currently sits on a stack of 52,400.
Both of these high rollers will be looking to end Day 1 among the chip leaders, and we will be sure to tack their progress as the tournament continues.
