Why 7-2 Offsuit Is the Worst Starting Hand in Hold'em

The hand everyone names

There are 1,326 ways to be dealt two cards, which sort into 169 distinct starting hands: 13 pairs, 78 suited hands and 78 offsuit hands. At the bottom of nearly every ranking sits 7-2 offsuit, a seven and a deuce of different suits. Here is what makes it so weak, and what the hand teaches about every other weak hand you will be dealt.

Four problems in two cards

• Seven high. When nobody pairs, the higher cards win. A seven loses to any ace, king, queen, jack, ten, nine or eight.
• No straight with both cards. A straight spans five consecutive ranks. The 2 and the 7 are six ranks apart, so no straight can contain both. Any straight you make uses one of your cards and four from the board, which means the board itself is nearly a straight and anyone holding the top card beats you.
• No flush. Different suits means you need four cards of one suit on the board to make a flush with one of yours, and then everyone with a higher card of that suit has a better flush.
• Small pairs. When 7-2 hits the flop it makes a pair of sevens or a pair of deuces. Against a pair of nines, you are drawing to two cards in the deck.

What the numbers say

Against one random hand, 7-2 offsuit wins about one time in three. Against pocket aces it wins about one time in eight. For comparison, a hand like J♠ T♠ wins roughly 57% against a random hand, and pocket aces win about 85%.

Honest footnote: against a single random hand, a couple of hands such as 3-2 offsuit test about as badly. 7-2 keeps its title because it is the lowest hand that cannot make a straight with both cards, and because the pairs it makes are so small. At a full table, where several hands compete, those weaknesses count for more.

Suited doesn't rescue it

7♥ 2♥ looks friendlier. It isn't much. Two suited cards make a flush by the river about 6.5% of the time, roughly one deal in fifteen, and a seven-high flush loses to any higher heart. Suitedness adds a little; it does not turn junk into a hand.

What 7-2 teaches about every other junk hand

7-2 is not a special case. J♣ 3♦, 9♠ 4♥ and 8♦ 2♣ lose money for the same reasons: a weak top card, no way to make a strong straight, small pairs when they hit. The useful habit is to recognise the whole family. A tight-aggressive player at a nine-handed table voluntarily plays about one hand in five. The other four go in the muck without a second look, and 7-2 is simply the easiest of them to let go.

Mistakes beginners make with it

1. Playing it "for fun". Some home games pay a bounty to anyone who wins a pot with 7-2. That is a side bet, not a reason, and the bounty rarely covers what the hand costs.
2. Calling a raise because it's cheap. Out of position with seven high you will usually miss the flop and fold, and when you hit a pair you will often be second best. The chips you save by folding preflop are the easiest chips in poker.
3. Bluffing with it because "nobody puts me on 7-2". A bluff works on the fold rate and the board, not on surprise. If a bluff is good there, it is good with any two cards, and you would rather have a hand with a backup draw.

The few spots where you see a flop anyway

• In the big blind when everyone limps. You can check and see three free cards. Hit two pair or better and you have a hand; hit one pair and play it cautiously.
• Very short stacked, heads-up or against the blinds. With a handful of big blinds left and the action folded to you on the button, shoving any two cards can be right because the blinds are worth so much relative to your stack. That is a stack-size decision, not a vote of confidence in the hand.

Everywhere else, fold it before you have to think.

A quick self-check

Over your next 30 play-money hands at a full table, count how many you fold before the flop. If it is fewer than about 24 of the 30, you are playing hands from the 7-2 family somewhere. Find them.
