In the March 28 issue of Card Player, Phil Hellmuth discusses a hand featuring set over set. In a sidebar entitled Poker Odds, presumably written by CP staff, the following is stated:
In a 10-handed game in which two players have been dealt pocket pairs, the chance of both players flopping sets is less than 0.1 percent.
I have no desire in calculating this probability and will accept their 0.1 percent. What I do find particularly funny is the redundant pre-condition of "in a 10-handed game". It doesn't matter if it's 10-handed, 5-handed or heads-up; if two players have been dealt pocket pairs, the chance of both players flopping sets is the same.
