Straddle
A voluntary blind bet — usually double the big blind — posted before the cards to buy the last preflop action.
In a $1/$2 game, the player under the gun can announce "straddle" and post $4 blind. Action then starts to their left, and the straddler gets the final decision preflop, like a third blind. Variants multiply fast at home games: button straddles, Mississippi straddles from any seat, re-straddles that double again. Every one of them changes the game more than most players realise.
The straddle's real effect is mathematical: it halves everyone's stack depth in big-blind terms. A $200 stack at $1/$2 is 100 big blinds — comfortably deep. With a $4 straddle, that same $200 is 50 straddles, and correct strategy compresses accordingly. Pots grow, SPR shrinks, and speculative hands like small pairs and suited connectors lose value because there's less money behind to win when they hit.
Is straddling profitable? Almost never for the straddler — you're posting dead money out of position. Players do it anyway to create action, and that's the point: a straddled pot is looser, bigger and more fun, which keeps the game alive and the gamblers happy. If your edge on the table is real, playing in the bigger game the straddle creates can still be worth it even though the straddle itself loses money.
Home games need straddle rules written down: allowed or not, from which seats, capped at how many re-straddles, and how it interacts with the buy-in rules. "We sometimes straddle" is how arguments start. Agree it before the first hand, post it with the house rules, and let your session log record the wilder nights for what they were. If the straddle crowd also drinks and gambles, those are often the most profitable nights your game runs — bring a full buy-in and a clear head.
