# Call or Fold: 3 Outs vs 1/2 pot, Flop

A half-pot bet asks for 25.00% and 3 outs on the flop give 12.49%, a margin of -12.51 points and a fold.

A half-pot bet on the flop is too expensive to call with 3 outs. You hit 12.49% of the time by the river and the call needs 25.00%.

- Verdict: Fold (3 outs, flop, half-pot bet)
- Chance to hit by the river: 12.49% (two cards to come)
- Equity the call needs: 25.00% ($50 into a pot of $200)
- Margin over the price: -12.51 points (your chance minus the price)

## How the verdict is reached

This is one of the easier spots. 3 outs on the flop reach 12.49% by the river, the half-pot bet asks for 25.00%, and the 12.51-point gap favors folding.

Count one overcard to top pair and you land on 3 outs. With 47 cards unseen, the next card helps 6.38% of the time.

## The same spot in dollars

- Pot when the bet arrives: $100
- Bet: $50
- Cost to call: $50
- Pot with your call in: $200
- Net gain when you hit: $150
- You lose on a miss: $50
- Chance to hit by the river: 12.49%
- Expected value of calling: -$25.02
- Equity needed to break even: 25.00%
- Margin, to four decimals: -12.5116 points
- Break-even count of outs: 6.23 outs
- Outs above the price: -3.23 outs

Expected value says the same in dollars. Win the whole pot on a hit, lose your call on a miss, add no more betting, and the call loses $25.02 on average: $18.73 in, $43.76 out, -0.500 per dollar called.

Read as odds: 7.01 : 1 against you, 3 : 1 from the pot.

A common slip is to divide the bet by the pot after the bet but before your call. That gives 33.33% instead of 25.00% and would put your margin at -20.8449 points. Using the bet over the starting pot, 50.00%, is further off and would put it at -37.5116 points.

## Implied odds that would change the answer

Think of it as a missing $200.37. When the draw hits you must collect that much beyond the pot for the $50 call to pay for itself, 4.01 times your call.

Price of a half-pot call with future winnings added, 3 outs on the flop

| Future winnings | Price with them | Your chance minus price | Value of the call | Call? |
| --- | --- | --- | --- | --- |
| $0 | 25.00% | -12.51 points | -$25.02 | Fold |
| $50 | 20.00% | -7.51 points | -$18.78 | Fold |
| $100 | 16.67% | -4.18 points | -$12.53 | Fold |
| $250 | 11.11% | +1.38 points | +$6.20 | Call |
| $500 | 7.14% | +5.35 points | +$37.42 | Call |

Another way to close the gap is more outs. The fewest outs that call a half-pot bet on the flop is 7; with 7 outs you would hit 27.84%. That is 4 more outs than the 3 you hold.

## Which chance to use

3 outs against a half-pot bet, one view per row

| Cards counted | Chance | Margin over price | Value of the call | Verdict |
| --- | --- | --- | --- | --- |
| By the river, two cards | 12.49% | -12.5116 points | -$25.02 | Fold |
| Next card only | 6.38% | -18.6170 points | -$37.23 | Fold |

Both views point the same way. By the river you hit 12.49%, on the next card 6.38%, and the price is 25.00%, so the fold holds whichever number applies.

## Neighbors of this draw

Move up or down a few outs and watch the verdict. Every extra out is worth about 3.98 points on the flop, and the price stays at 25.00%.

| [three-quarter-pot](https://georgelipoker.com/call-or-fold/3-outs-flop-vs-three-quarter-pot.md) | 30.00% | -17.51 points | Fold |

| 1.5x-pot | 37.50% | -25.01 points | Fold |
| 2x-pot | 40.00% | -27.51 points | Fold |
| 3x-pot | 42.86% | -30.37 points | Fold |
| 4x-pot | 44.44% | -31.96 points | Fold |

Your draw can face a bet of up to 0.17 times the pot ($16.65 on a $100 pot) and still break even. That is under the quarter-pot bet, so none of the 12 sizes is a call.

## Questions

### Is a call correct with 3 outs against a half-pot bet on the flop?

Math says fold. The half-pot bet of $50 needs 25.00% equity, 3 outs on the flop give 12.49%, and the margin is -12.51 points. Assuming a whole pot won on a hit and no further bets, the call is worth -$25.02 on average.

### How many outs do you need to call a half-pot bet on the flop?

A call starts to work at 7 outs: 27.84% to hit versus 25.00% needed. One out fewer drops the chance to 24.14%. You hold 3, which is 4 fewer than the minimum.

### How many cards should you count when a half-pot bet arrives on the flop?

It depends on what follows, but here it does not matter. If the hand ends here, count both cards: 12.49%. If another bet is coming on the turn, count one card: 6.38%. Against 25.00%, both say fold.

## How this is computed

Everything is computed from the closed form. Pairs without an out: 946 of 1,081. The rest, 12.49%, hold at least one out.

What is held fixed: the call equals the bet, so the price is $50 / $200 = 25.00%; the pot is won whole on a hit; there is no further betting; and each of the 47 unseen cards is as likely as any other. Opponent cards are not removed.
