Big Blind
The big blind is the larger forced bet posted two seats left of the button before the deal. It sets the minimum bet and is the last to act preflop.
The big blind is the larger of the two forced bets in Texas Hold'em, posted by the player two seats to the left of the button before any cards are dealt. It sets the size of the minimum bet and is the unit players use to measure stacks and win rates: "I have 100 big blinds" or "I won 5 big blinds per 100 hands." The seat itself is also called the big blind.
Big blind rules
- Stakes: in a 1/2 game, the big blind is 2. The small blind is usually half that.
- Minimum bet: any bet on any street must be at least one big blind, and the minimum preflop raise is to two big blinds.
- Acting last preflop: the big blind is the final player to act before the flop.
- The option: if everyone just calls or folds to the big blind, they may check and see the flop for free or raise. This is called "having the option."
- Postflop: the big blind acts before every player except the small blind.
Why the big blind defends so often
Because the big blind already has a full bet in the pot, calling a raise costs less than it does for anyone else, and the price is often very good. When the button raises to 2.5 big blinds and the small blind folds, the pot is 4 big blinds (2.5 + 1 + 0.5) before the big blind acts. Calling costs 1.5 big blinds to play for a final pot of 5.5, so the big blind needs only 1.5 / 5.5, about 27% equity, setting aside position. That is why the big blind defends a wide range against late-position raises.
The catch is that the big blind will play the rest of the hand out of position against everyone except the small blind, so not every cheap call is a good one.
Example hand
Blinds 1/2. The button raises to 5, the small blind folds, and you hold 8♥ 7♥ in the big blind. Calling 3 more chips to play for an 11-chip pot is attractive with a suited connector. The flop comes 9♥ 6♣ 2♥: you have an open-ended straight draw and a flush draw. You check, the button bets 4, and you can check-raise as a strong semi-bluff with around 15 outs.
Compare holding 9♣ 3♦: even at a good price, that hand plays poorly and usually belongs in the muck.
Big blind tips
- Defend wider against late-position raises and tighter against early-position raises.
- Think of your blind as already part of the pot, not something you must "protect" at all costs.
- Use your option in limped pots to raise strong hands rather than always checking.
Frequently asked questions
What does having the option mean?
If nobody raises preflop, the big blind gets the option to check and see the flop or to raise, since their blind already matches the bet.
How much is the big blind?
It is the second number in the stakes, so 2 in a 1/2 game. It also sets the minimum bet for the game.
Should you always defend your big blind?
No. Defend more against late-position steals and with hands that play well, but fold weak hands, especially against early-position raises or large raise sizes.
