Blind vs blind: the most common spot, and the most badly played
Everyone folds, it's your turn to act in the small blind, and only the big blind is left. This duel comes up every orbit where nobody opens, which makes it one of the spots you play most often. And yet it is also one where micro-stakes players leave the most money behind — either by playing the SB like a normal position, or by defending the BB as if facing an under-the-gun open.
Why this spot is different
In blind vs blind, two forces pull in opposite directions. On one side, the SB acts first preflop against a single opponent: its opening range can therefore be very wide, much wider than from the cutoff, for example. It is the steal logic pushed to its maximum: only one person left to fold out.
On the other side, the SB will be out of position on the flop, turn and river. Every hand you open, you will have to play acting first, without knowing what the BB will do. That is why a wide SB opening range must still be built with hands that play well postflop — high cards, suited aces, connectors — rather than any two cards.
The BB, for its part, already has a full blind in the pot, gets an attractive price to call and will have position for the rest of the hand. Result: this is the spot where it must defend the widest in the whole game. If you want the details of BB defense depending on the opener's position, we covered it in our article on defending the big blind.
Small blind side: raise, limp or fold
The SB has three options when everyone has folded. None of them is "forbidden", but each has its conditions.
Raising (raise first in)
The default option with most of your playable range. You take the initiative, you can win the pot immediately if the BB folds, and you build a pot with your best hands. The drawback: you play the rest of the hand out of position, so your range has to be made of hands that hold up postflop.
Limping (completing)
A legitimate option, as long as it's a real strategy and not a reflex with mediocre hands. A limp built only with weak hands gets read within a few dozen hands: an attentive BB then raises every one of your limps. If you limp, put some strong hands in there too so you can re-raise when the BB attacks.
Folding
Always on the table for the bottom of your range. Losing your half-blind isn't a disaster: the real loss is playing bad hands out of position against a player who has position on you for the whole rest of the hand.
If you are new to these spots, a "raise or fold" strategy is the easiest to apply without mistakes. It is less refined than a mixed strategy with a limp, but it avoids the most common trap: limping all your medium hands and ending up calling a raise out of position with a hand that doesn't want to play a big pot.
On sizing, a raise slightly bigger than elsewhere is often justified from the SB: since you will be out of position, you prefer the BB to call less often, or to call into a pot where your initiative weighs more.
Big blind side: defend wide, attack the limps
Facing an SB raise, the BB has to remember that the opposing range is wide. Many players defend here as if facing an open from the first player to act, throwing away perfectly playable hands. That is exactly what the SB is hoping for.
Your defense splits between calling — most of your hands, since you have position — and 3-betting, with your best hands and a few blocker hands that play poorly as a call. A 3-bet is all the more effective from the BB because the SB, opening wide, cannot call with its whole range.
Facing an SB limp, the BB has a huge edge: it can check for free or raise to isolate. If your neighbor limps only weak hands, raise them often and big. If they mix strong hands into their limps, be more careful with your light raises and mostly take advantage of your position postflop.
The 3 postflop mistakes that cost the most
Automatic c-bet from the SB
You raised, the BB called: that doesn't mean you should bet every flop. Out of position, against a very wide defending range that hits a lot of low, connected boards, an automatic c-bet gets check-raised and costs you. Check more on boards that favor the BB.
BB too passive when checked to
When the SB raises and then checks the flop, its range is often capped. A BB that checks behind every time lets pots slip that it could take with a simple bet. Position is your edge: use it.
Not adjusting enough
The blind vs blind duel comes up dozens of times per session against the same table neighbors. It is the ideal spot to exploit a specific tendency: a neighbor who over-folds their BB gets stolen from relentlessly, a neighbor who 3-bets a lot gets trapped with strong hands.
Measuring what you actually lose between the blinds
The blinds are losing positions for almost everyone: you put money in without choosing to. The goal is therefore not to win there, but to lose as little as possible. And that is where gut feeling misleads you the most: you remember the big pot lost with second pair, rarely the dozens of small pots given up through excess passivity.
The only reliable way is to look at your results by position on your real hand history, then review a few blind vs blind hands specifically: do you open too tight from the SB? Does your BB fold too much against SB raises? Do you c-bet every flop out of position? Those three questions are often enough to find the leak.
Frequently asked questions
What does "blind vs blind" mean in poker?
It is the situation where every player folds to the small blind: only the SB and the BB remain, facing off heads-up. The SB acts first preflop but will be out of position on every following street.
Should you limp or raise from the small blind when everyone folds?
Raising is the simplest and most robust option for most players. Limping can be profitable if it is built as a real range (with some strong hands in it), but a limp reserved for weak hands is easily exploited by an attentive BB.
Why should the BB defend wide against the SB?
Because it already has a full blind invested, it gets a good price to call, and above all it will have position on every street. Against an SB that opens wide, folding too often means handing over the blinds for free.
How do I know if I play my blind vs blind spots badly?
Look at your results by position over a large enough sample: if your SB and BB lose noticeably more than normal, especially in pots played between the blinds, that is a signal. A hand history analysis tool isolates these spots for you instead of leaving you to guess.
