Pre-flop Match ups

[Jedi Poker]

Q#1. Obviously, the best starting hand in texas holdem is the AA. But what top three starting hands match up the WORST against it? In other words, what hands would you least want to go up against AA?

Q#2. How much of an underdog are these starting hands against AA: 72 offsuit, 23 offsuit, 74 offsuit.

Thanks.

I think the worst match up is probably something like A9 with the 9 sharing a suit with one of the AA.

From two dimes:

As for yours ... if you make the cards suited with the AA for the worst results, you get:

Oh and as for bad beats ... I lost this all-in battle in a tourney not too long ago.
