Double Barrel

Also known as: double-barreling, second barrel, turn barrel

Firing a second bet on the turn after c-betting the flop, with value or as a continued bluff.

A double barrel is the turn bet that follows a flop c-bet. Whether to fire again is an equity-and-card question: which turns improve your range relative to the caller's, and which cap you.

Good double-barrel cards:

Your barreling bluffs should carry equity: a gutshot, an OESD, or a backdoor-turned-live draw makes a far better barrel than pure air, because you retain a way to win when called. Maintain a sane bluff-to-value ratio tied to your sizing — larger turn bets demand more value or stronger blockers behind the bluffs.

Give up on bricks that change nothing and on cards that smash the caller's range. Barreling every turn is a classic, expensive leak.

Example

You c-bet 8♦6♣4♠ as the PFR and get called. Turn 5♥ gives you the gutshot-plus-overcards combos and many flush/straight threats against the caller's pair-heavy range — a strong barrel card. Turn 8♠ instead (pairs the board, helps the caller's trips and improves few of your bluffs) is a frequent check-back.
