Re: Key holdem odds to memorize
Hey Derek,
The chance of flopping a two pair which uses both your cards is 1 in 50, and the chance of flopping trips is about 1 in 77.
2 pair: 9*44/ncr(50,3)=.0202
trips: 3*2*44/ncr(50,3)=.013
Practically speaking, the odds of flopping 2 pair or trips are so low as to be negligible. This is why playing hands like J5o is unprofitable even from the small blind with 8 limpers and a guaranteed check from BB.
Whenever you think to yourself, "Hey, there's always the chance I flop 2 pair," toss your cards in the muck.
