What is a semi-bluff?

A bet or raise with a hand that is not the best now but can become it: it wins when the opponent folds, and some of the times they call.

How is it different from a bluff?

A pure bluff has almost no equity when called; a semi-bluff keeps some, so it needs fewer folds to be profitable.

How many outs does a flush draw plus an open-ended straight draw have?

In this page's example, 15: 9 cards of the suit and 6 cards that complete the straight without being of the suit, so 32.6% to hit on the river.

Semi-Bluff in Poker: A Draw That Wins Two Ways

By the Poker Puzzle Trainer team · Published October 21, 2026

A semi-bluff is a bet or raise with a hand that is not the best now but can become it, most often a draw. It wins two ways: when the opponent folds, and some of the times they call, because the draw hits. That is what separates it from a pure bluff, which wins almost only through the fold.

8♠7♠ in the big blind on the turn

In the big blind with 8♠7♠, you called the button's c‑bet on T♠ 6♦ 2♠. Turn 5♥, the button bets 60% of the 11bb pot, 85bb deep. Fold, call or check‑raise 3x?

See the answer

8♠7♠ has 15 outs: 9 spades for the flush and 6 cards (three 9s and three 4s that are not spades) for the straight, so 32.6% to hit on the river.

Option	What you add	What it needs
Call	6.6bb	27.3% equity
Check‑raise to 19.8bb	19.8bb	52.9% folds if it were a pure bluff

8♠7♠'s equity if the check‑raise is called, with the river to come:

Button's hand	8♠7♠'s equity
K♥Q♥	47.7%
A♠K♦	45.5%
A♥T♦	34.1%
4♦3♦	31.8%
T♥T♣	29.5%

When called, the check‑raise keeps at least 29.5% equity against each of these hands: it does not need the 52.9% folds of a pure bluff. The expected answer is the check‑raise.

Bluff and semi-bluff side by side

	Pure bluff	Semi-bluff
Equity when called	almost none	the draw's
How it wins	only through the fold	through the fold and when the draw hits
Folds needed	the full price of the bet	fewer, depending on the equity
