Double Barrel Poker Strategy: When to Bet the Turn Again
A double barrel in poker means betting the turn after your flop c‑bet was called. Keep betting with hands that are still ahead of the hands that call, with strong draws, and on turn cards that favor your range. Mostly give up with hands that have no pair and no draw: the caller's range is stronger than on the flop, and a 75% pot bluff on the turn has to work 42.9% of the time.
Top pair on the turn after a called c‑bet
On the button with K♦9♦, your 33% c‑bet on K♠ 6♣ 2♥ was called. The turn is the T♣ and the big blind checks. Check back, bet 40% or bet 90%?
What K♦9♦ is up against
Equity of K♦9♦ on K♠ 6♣ 2♥ T♣, with the river to come:
| Big blind's hand | What it holds | Your equity |
|---|---|---|
| A♥K♥ | better king | 6.8% |
| K♥8♥ | worse king | 86.4% |
| T♠9♠ | second pair | 95.5% |
| 7♣6♦ | third pair | 88.6% |
| Q♣J♣ | flush draw + straight draw | 68.2% |
See the answer
Worse kings, smaller pairs and draws can all call, so betting earns value and charges the draws. Better kings call too, which is why the size stays small: 40% of the pot risks little when you are behind.
The price of a turn bluff
A bluff needs bet ÷ (pot + bet) folds:
| Turn bet | Folds needed |
|---|---|
| 33% of the pot | 24.8% |
| 40% of the pot | 28.6% |
| 75% of the pot | 42.9% |
| 120% of the pot | 54.5% |
The hands that called the flop fold less often than the whole range did. That is why the turn bluffs that work best still have outs when called. The threshold is explained in how often a bluff must work.
Top pair and the nut flush draw on the turn
In the cutoff with A♠Q♠, you c‑bet Q♣ 8♦ 4♠ and the big blind called. The turn is the 2♠ and the big blind checks. Check back, bet 45% or bet 120%?
See the answer
Top pair, top kicker plus the nut flush draw: 95.5% against K♦Q♦ and 97.7% against J♦J♥, and the spades keep it alive when behind, with 25% against two pair Q♥8♥ and 18.2% against a set of eights. The hand is rarely in bad shape, worse queens can pay, and a big bet builds the pot for the river.
When to stop barreling
| Your hand on the turn | Barrel? | Why |
|---|---|---|
| still ahead of the hands that call | yes, size by what calls | value and protection |
| strong draw | yes, often | wins by a fold or by hitting |
| turn card that helps the caller | usually check | e.g. a 5 on 8‑7‑6: any 9 or 4 now makes a straight |
| no pair, no draw | mostly check | needs folds the calling range rarely gives |
