View Full Version : Preflop matchup matrix: win, lose, tie probabilities

I was wondering if anyone had a good reference for the matrix of 169x169 preflop matchup possibilities, listing win, lose, and tie probabilities for each.

I have a reference which lists equity for each of the matchups, but this isn't quite what I'm looking for. I'd like to be able to handle the case of split pots properly in an analysis I'm doing, so I need to know probability of ties, which is not possible by looking at an equity matrix.

Anticipating the first reply, I know twodimes.net can give me any specific matchup, like AcKd Ts9s. What I want to know is the enumeration of matchups for the 169 preflop hands: pairs, suited, and offsuit hands. In each of those is the weighted probability of each of the possible specific matchups which fit the category for the preflop hands.

Don't forget that the odds for AdKd vs. QsQd are different than those for AcKc vs. QsQd, etc. even though they both count as AKs vs. QQ. Same with AdAc vs. KdKc (different odds than AdAc vs. KhKs) So if you want precision it can't really be only the 169 hands.

No, what I'm looking for is the weighted average of each of the possibilities.

Think of it this way: If I say I want to know the win % of AA vs. any pair, I can do so by determining the win % against each possiblitity and weighting it by its likelihood. There is no loss of "precision." It is simply a different question.

Why?

You want to win money, not know "exact numbers." A couple of percentage points give a low margin of error. That margin is low enough to not affect your equity.

Sorry I can't help you, but I would really like this equity matrix you have. Where can I obtain it? Thanks.
