Shawn Buchanan got his money in on a flop. Tad Jurgens was right there to look him up, both men sharing a similar stack size. Here's what they were working with:
Buchanan: (two pair, straight draw)
Jurgens: (pair, flush draw)
The turn was a blank for both players, but the river was not a blank at all. The gave Jurgens the winning flush, and he had Buchanan slightly covered when the stacks were matched up.
So then, we've lost Buchanan in 22nd place while Jurgens nearly doubles to about 45,000.
