The question basically says it all. I've always heard/played 2 7 offsuit as it was the worst hand, but I never looked more into it, it just made sense. Does anyone know if there is any hand worse for preflop (statistically) than 2 7 offsuit in Texas Hold'em?

Thanks!

  • 27o is particularly bad at full ring games. 23o is worse head's up and probably with 3 or 4 players too. In fact 27o will win more often than 43s heads up. The more players in a hand, the more likely you'll need to make a strong hand like a straight or flush to win. 43s is playable if you can get in for cheap preflop in position at a full ring table, but it is a horrendous hand heads up.

  • What @Paulpro said, basically 72o has nothing to even start with, no flush, no straight, worst kind of 1-pair and an almost always bottom 2-pair. Some players are even playing it out just for fun. 32o is the worst HU because there the higher card matters a lot and a 72o is still a 7-high where HU counts.

  • One of the interesting things about poker is that which hand is best depends on which hands it's against, for instance each of these hands has an advantage against the hand after it in a heads up match: 56s > 22 > AKo > 56s

    @Paulpro, make it an answer to reduce the commentary ;)

I once spent an afternoon analyzing 7-2 with Poker Probe (An old program by Mike Caro). I was curious if there was any situation that justified making a call with 2-7. PP was a pretty simple program, you could run a hand against a configurable hand, or a number of random hands. It for example could tell you how often a particular hand would hold up against a particular number of players. It did not account for anything but the cards.

My conclusions at the time about 2-7 where pretty much the obvious, it should never be played. 2-7 even suited has such a low rate of return that it simply should never be played.

The more players in a pot the lower the EV is with the hand.

The only situation I could find were you could actually place a chip in the pot and get a slight positive EV on that chip was when your were against one opponent and could get five to one on that chip. If the blinds are ten and fifteen, and you are in the small blind you have a slight positive EV for the five dollar call when head up, if there is another limper in the hand the EV goes negative for the five dollar call. This EV is so low, just a very low percentage like 2 or 3 percent that factors like rake and the bad position your in, the possibility the BB raises, make it a negative play. Even in a time game the time you waste playing the hand might eat up any positive EV.

I looked at a lot of hands and none play as bad as 2-7 against a large field. However that really is not an answer to your question because 2-7 has an advantage over a lot of hands like 5-3, 6-4, 3-4, and other hands that may play better then 2-7 against a larger field.

I think it is safe to say that when compared to all other hands, that 2-7 is the most unplayable hand in poker. Being the lowest possible unconnected two cards the hand never gets the number of outs as even two smaller cards that are a little more connected.

It depends on how many players are in the pot. Using the pre-flop calculator and assuming you only know your own hand, here is a table of the winning odds (calculated at https://www.888poker.com/poker/poker-odds-calculator):

 Players | 3-2o | 7-2o | Worst Hand
---------|------|------|------------
      3  | 17.7 | 18.7 | 32o
      4  | 12.7 | 13.1 | 32o
      5  | 10.8 |  9.7 | 72o
      6  |  8.1 |  7.1 | 72o

So heads up to 4-handed, 32o is the worst hand statistically. 5-handed and up, 72o is the worst hand statistically.

The odds are different if you know two hands in the game (e.g., player 1 with 72o vs player 2 with 32o), and there the 32o is worst until you are 6-handed, in which case you both should be laying those hands down.

I was just having this conversation with a friend. So I wrote a little program to explore the idea and graphed the data showing when 72o becomes a slightly better hand than 32o.

Basically, when the 32o straight connects it holds up better with more people on the table while the range that 72o beats is no longer as valuable. Making 72o the worst hand to hold statistically. But when there are fewer players (2-4) the 72o will win more w/over card than the lower straight connects.

On the graph below the y axis is the win rate and the x axis is the hand against number of players.

72o vs 32o, 2 through 10 players

  • The chart would be more readable if you put the colors on a legend and combined them into one x-value. And you don't need "players" on each x-value. What did you use to create it? Apr 12 at 2:30
  • You're right.. I will update the graph to make it more clear. I used matplotlib for the graph along with github.com/ihendley/treys for the hand evaluation.

No. Against unknown hands, cash or tournament, you'd be hard-pressed to have both the implied odds and the fold equity to play this hand. The only reason to play this hand would be if it was limped around to you in the BB (which is why open-limping isn't wise: BB can hit his trash he would have folded).

  • This is not the only reason. If you are chip leader of a tournament at the bubble, you can raise preflop this hand in late position to steal the blinds.
