What Is a Double Gutshot Straight Draw?

A double gutshot — also called a double belly buster — is a straight draw in which two separate inside cards complete your hand instead of one. It holds eight outs, exactly as many as an open-ended straight draw, but the ranks are scattered rather than consecutive, so the draw is far harder for your opponent to see. Counting one as a four-out gutshot is among the cheapest leaks you will ever fix.

Spotting one on the flop

Stop looking for four cards in a row. List every rank in play, your two cards and the board together, then ask which single rank would give you five consecutive. If two different ranks answer, you hold a double gutshot.

Say you open Q♠T♠ from the CO and the flop comes 9♦8♥6♣. Nothing about that texture announces a straight draw for you: your two cards are not connected to each other, and the board is only loosely connected to them. Yet a 7 makes T-9-8-7-6 and a J makes Q-J-T-9-8. Four sevens plus four jacks is eight clean outs.

Draw	Outs	Equity by the river
Gutshot	4	roughly 16%
Double gutshot	8	roughly 32%
Open-ender	8	roughly 32%

Two fills, eight outs. A double gutshot is an open-ender in disguise, so price it like one.

Why it matters

The rule of 4 puts eight flop outs near 32% by the river, and the rule of 2 puts them near 17% on any single street. That is enough to semi-bluff with, and enough to continue against most flop bets. In a $40 pot on 9♦8♥6♣, betting $25 with Q♠T♠ folds out plenty of high cards now and improves to the winner roughly a third of the time when it does not.

The disguise pays you again on the turn. When an open-ender fills, the board shows an obvious run and the pot shuts down. When your jack lands here, the board reads 9-8-6-J, which misses most calling ranges entirely — and your opponent keeps betting into the nuts.

Know which end you are filling before you commit. The J gives you the best possible hand. The 7 gives you T-9-8-7-6, a straight that any lone ten chops with and J-T beats outright, so the low end deserves caution rather than a stack. When the money is deep enough for that to matter, put the spot into the poker equity calculator instead of trusting a rule of thumb.
