View Full Version : Favorite over random hands?

Against one opponent I know that Q7 or better is a favorite against a random hand. But really is 'better' here? In an allin showdown heads up any unpaired hand with both cards lower than queen would have the worst of it, so what hands should you consider 'better' when playing heads up?

I also wonder where the line is drawn against two or three opponent also. Not just to be better than average, but more than 50% chance that you are better than both..

Heads up all in, you can rank the hands in poker order: first the pairs, Ace to 2, then by high card, for equal high cards, take the hand with the better second card.

Straights and flushes are tricky. Generally, suited connectors are about as good as unsuited hands with one higher and one lower card. But that doesn't give a clean rank order. 7h 6h is about even with Ks 2c, but will usually lose to 9c 8s; even though the Ks 2c beats 9c 8s most of the time.

Here is the ranking based on actual money won and lost in heads up play (not necessarily all-in) at Poker Room (http://www.pokerroom.com/games/evstats/positionStats.php?players=2). This does not conform exactly to the mathematical probability of winning a showdown, but it's pretty close. Anyway, it's a different way to address the question.

here (http://www.gocee.com/poker/HE_Value.htm) is a page that has the answers to all the queries you may have regarding "how does my hand compare to x random hands?"*

for what it's worth, I think Q7 is called the "computer hand" because someone somewhere in the late 70's said that a computer simulation told him that's the worst hand that's still profitable in heads-up hold em. According to the Gocee chart, however, K2o is the worst hand that is still profitable heads-up (Q7 is still profitable, however - suited it has a 2.7% equity edge, and unsuited has a 1.9% equity edge - it's just not the worst of the profitable hands).

*just for completeness, I should mention that there is a slight difference between a hand that is up against x random hands and a hand that is up against x random hands given that y opponents have already folded. This is because if you are at say a 9-handed table and the first six players fold their hands, they are telling you something about the cards that they held (for a very conservative example, in a ring game they're certainly telling you that none of them had AA or KK). It's not a ton of information by any means, but it's some. I have no idea whether or not the distribution of cards left given that y bad hands have been folded means a statistically significant difference regarding the hands that you might be up against, but I just mention it to be clear that acting first in a four-handed game isn't exactly the same as acting fifth in a nine-handed game when four people have already folded in front of you (it would be precisely the same if say you were playing online and the first four people were all sitting out - in that case, they're set to fold anything, so they're just as likely to fold AA as they are 72o).
