The straddle: how it changes a live cash game
A straddle is an extra blind, usually twice the big blind, posted before the cards are dealt. It is common in live cash games and it changes more than the size of the pot: stacks become shorter in blinds, speculative hands lose value and position matters even more. This lesson explains how a straddle works, how to adjust and whether to post one yourself.
What a straddle is
In the most common form, the player under the gun, to the left of the big blind, puts in twice the big blind before the deal. At £1/£2 that is £4. The straddle then works like a bigger big blind:
- Action before the flop starts with the player to the straddler’s left.
- Anyone who wants to play must call at least the straddle, and the smallest raise goes up with it.
- The straddler acts last before the flop and can raise even if everyone else just calls.
- After the flop, the straddler acts in normal seat order, so under the gun is still an early position.
House rules vary. Some rooms allow a button straddle, a Mississippi straddle from other seats or re-straddles, and some do not allow straddles at all. Ask the floor before you play if you are unsure.
What a straddle does to the game
A straddle doubles the size of the forced bets, so it halves the stacks when they are measured in blinds. A £200 stack at £1/£2 is 100 big blinds. With a £4 straddle on, it is 50 straddles. Every preflop decision now plays like a game with half the stack depth.
The pots also get bigger relative to the stacks. Compare two pots at £1/£2 with £200 stacks:
| No straddle | £4 straddle | |
|---|---|---|
| Open raise | £10 | £20 |
| Who calls | The big blind | The straddler |
| Pot on the flop | £21 | £43 |
| Left behind | £190 | £180 |
| Stack-to-pot ratio | 9.0 | 4.2 |
With an SPR around 4, top pair with a good kicker is often worth all the chips. With an SPR around 9, it often is not. The straddle makes one-pair hands bigger and drawing hands smaller.
Opening with a straddle on
Treat the straddle as the big blind and scale your opens from it. If you normally open to 4 big blinds, open to about 4 straddles. Then adjust your ranges:
- Tighten a little from every seat. The straddler is one more player who can raise behind you, and the open costs more.
- Favour high cards and pairs. Hands such as ace-queen and king-queen gain value when stacks are shallower, because top pair wins more often at a low SPR.
- Play fewer speculative hands. Small pairs, suited connectors and weak suited aces need deep stacks to pay off when they hit.
The opening ranges lesson gives a chart for a normal game; with a straddle on, start from the next tighter seat. From the cutoff, for example, play something close to the hijack range.
Small pairs and set mining
Set mining means calling a raise with a small pair mainly to flop three of a kind. You flop a set or better 11.8% of the time, odds of about 7.5 to 1 against. To pay for the misses, the pot plus what you win when you hit has to be big enough.
A common rule of thumb asks for at least 15 to 20 times the call in the stacks behind, because you will not always win a stack when you hit, and sometimes your set loses.
| No straddle | £4 straddle | |
|---|---|---|
| Raise you are calling | £10 | £20 |
| Stack behind after calling | £190 | £180 |
| Stack behind as a multiple of the call | 19 times | 9 times |
Without a straddle, calling £10 with a small pair meets the rule of thumb. With a straddle on, calling £20 with the same £200 stack gives only 9 times the call. That is barely above the bare 7.5 to 1 and assumes you win the whole stack every time you hit, which you will not. The implied odds calculator runs the same test for any draw.
Try it: is this a set-mining call?
Enter the raise you face and the stack left behind. Compare the multiple with the 7.5 to 1 against flopping a set.
Above the bare 7.5 to 1, below the 15 times rule of thumb. Profitable only if you win most of the stack almost every time you hit.
Uses the smaller of your stack and your opponent's. Ignores the money already in the pot and the times your set loses.
Should you straddle?
A straddle is a blind bet you post without seeing your cards, from a seat that acts early after the flop. Each orbit you straddle adds £4 at £1/£2 to what you already pay in blinds. In return you act last before the flop, and some tables play looser and bigger when straddles are on.
We do not have evidence that straddling is profitable for the player who posts it, and whether it suits you depends on your game. If you do straddle, note it in your session log. Over a large enough sample you can compare sessions with and without it, but a few sessions prove nothing either way. The variance calculator shows how wide the range of results is over a small number of hours.
Common mistakes
- Opening the same sizes as in an unstraddled game, so every open is effectively half the size.
- Calling raises with every small pair and suited connector out of habit, when the stack depth no longer supports it.
- Forgetting that the straddler acts last preflop and can raise a pot everyone has limped into.
- Assuming the straddle seat plays like the big blind after the flop. It still acts early.
- Straddling to chase losses. A straddle adds to what you pay and does nothing to change your edge.
Check yourself
At £1/£2 with a £4 straddle on, how deep is a £300 stack in straddles?
£300 ÷ £4 = 75 straddles. Without the straddle it would be 150 big blinds.
You call a £20 raise with 3♣ 3♦ and £180 left behind. How does that compare with the 7.5 to 1 against flopping a set?
£180 is 9 times the £20 call. That only just beats 7.5 to 1 even if you always win the full stack when you hit, so the call is thin. Without a straddle, a £10 raise with £190 behind gives 19 times the call.
Why does a straddle make top pair stronger?
A straddle makes pots bigger relative to the stacks. At a stack-to-pot ratio near 4, a strong top pair can usually get all the money in. At a ratio near 9, getting all the money in takes several big bets, and an opponent who puts in that much usually has two pair or better.
Key takeaways
- A straddle halves the stacks measured in blinds; open sizes and ranges should change with it.
- Shallower stacks favour high cards and big pairs, and cut the value of small pairs and suited connectors.
- The straddle seat acts last before the flop and early after it; treat posting one as a cost.

The set figure is the exact chance of flopping three of a kind or better with a pocket pair, counted over every flop. Straddle rules vary by room; the description covers the most common under the gun straddle.
Questions
What is the straddle rule?
A straddle is a voluntary extra blind, usually twice the big blind, posted by the player under the gun before the cards are dealt. It acts like a bigger big blind: everyone must call at least the straddle to play, and the straddler acts last before the flop. Rooms differ on button straddles, Mississippi straddles and re-straddles, so check the house rules.
What is the purpose of straddling?
Players straddle to raise the stakes of the hand, to act last before the flop and sometimes to make the table play looser and bigger. It costs a blind you post without seeing your cards.
Is it profitable to straddle in poker?
There is no evidence that straddling is profitable for the player who posts it. You put money in blind and play the hand from an early position after the flop. If you straddle, note it in your session log so a large sample can show how it works for you.
Which is the best straddle strategy?
There is no single best strategy, but a sound starting point is to treat the straddle as the big blind: open to the same multiple of it, tighten slightly from every seat, favour high cards and big pairs, and play fewer small pairs and suited connectors, because the shallower stacks cut their implied odds.
Who acts first when there is a straddle?
Before the flop, with an under the gun straddle, the player to the straddler's left acts first and the straddler acts last. After the flop the normal order applies, starting with the first player still in the hand to the left of the button.
