Hi all - I was just mucking around with the ever-so-useful Gocee chart of race probabilities for certain hands versus x number of random hands, to see what kind of equity edge the hands have.
Calculating the edge is simple, of course - e.g. AA has according to the chart an 85.3% probability of holding up over one random hand, and the average hand in a two-handed game has a 50% probability of winning, therefore AA has an equity edge of 35.3%, since it figures to win 35.3% more than its fair share of pots. Right so far? If so, then a curious thing arises when you look at the data. Here are the preflop equity edges for AA-TT against 1, 2, and 3 opponents. AA (1) 35.3%, (2) 40.07%, (3) 38.9% KK (1) 32.4%, (2) 35.57%, (3) 33.2% QQ (1) 29.9%, (2) 31.57%, (3) 28.5% JJ (1) 27.5%, (2) 27.87%, (3) 24.2% TT (1) 25.1%, (2) 24.37%, (3) 20.2% For AA-JJ, the preflop equity edge actually goes up when you add a second opponent, but then back down when you add a third! (it goes further down with more opponents for 3+ opponents or for TT or lower). Why is this?? What's so special about having two opponents as opposed to one that makes the edge increase? [Disclaimer: if you find some glaring incredibly boneheaded basic math mistake in my calculations, please point it out quickly before my window of opportunity to delete this post and save face erodes.
