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

Is a call right with 1 out on the flop against a two-thirds-pot bet? Chance 4.26%, price 28.57%, so fold.

On the flop, 1 out is not enough to call a two-thirds-pot bet. The price is 28.57% and the chance is 4.26%.

- Verdict: Fold (1 out, flop, two-thirds-pot bet)
- Chance to hit by the river: 4.26% (two cards to come)
- Equity the call needs: 28.57% ($66.67 into a pot of $233.33)
- Margin over the price: -24.32 points (your chance minus the price)

## Chance against price

4.26% against 28.57%: the draw trails the price by 24.32 points. On this flop against a two-thirds-pot bet, that is an easy fold.

The deck holds 47 unseen cards and one of them is your out, so a single card hits 2.13% of the time.

## A $100 pot, step by step

- Pot before the bet: $100
- The bet: $66.67
- Chips you put in: $66.67
- Pot with your call in: $233.33
- Net gain when you hit: $166.67
- Loss on a miss: $66.67
- How often you hit: 4.26%
- Expected value of a call: -$56.74
- Break-even equity: 28.57%
- Your chance minus the price, unrounded: -24.3161 points
- Fractional outs at the price: 7.20 outs
- Margin measured in outs: -6.20 outs

Over many identical spots, with the whole pot won on every hit, the call lost on every miss and no extra betting, calling loses $56.74 on average. Hits bring in $7.09, misses cost $63.83, and the ratio is -0.851 per dollar called.

Stated as odds, you are 22.5 : 1 against hitting and the call gets 2.5 : 1 from the pot.

Counting the pot without your call makes the price look like 40.00%, when the real price is 28.57%. On that mistaken price the margin would read -35.7447 points; on 66.67%, the bet over the starting pot, it would read -62.4113 points.

## Implied odds that would change the answer

The shortfall in dollars is $1,333.33: the amount a hit would have to win later for 4.26% to be enough. It equals 20.00 times your $66.67 call.

Price of a two-thirds-pot call with future winnings added, 1 out on the flop

| Future winnings | Price with them | Your chance minus price | Value of the call | Call? |
| --- | --- | --- | --- | --- |
| $0 | 28.57% | -24.32 points | -$56.74 | Fold |
| $50 | 23.53% | -19.27 points | -$54.61 | Fold |
| $100 | 20.00% | -15.74 points | -$52.48 | Fold |
| $250 | 13.79% | -9.54 points | -$46.10 | Fold |
| $500 | 9.09% | -4.84 points | -$35.46 | Fold |

Another way to close the gap is more outs. The fewest outs that call a two-thirds-pot bet on the flop is 8; with 8 outs you would hit 31.45%. That is 7 more outs than the 1 you hold.

## Two cards to come, or just one

1 out against a two-thirds-pot bet, one view per row

| Cards counted | Chance | Margin over price | Value of the call | Verdict |
| --- | --- | --- | --- | --- |
| By the river, two cards | 4.26% | -24.3161 points | -$56.74 | Fold |
| Next card only | 2.13% | -26.4438 points | -$61.70 | Fold |

Here the cards to come do not matter for the verdict. 2.13% on one card and 4.26% on two both say fold at a price of 28.57%.

## Questions

### Call or fold with 1 out on the flop against a bet of two thirds of the pot?

Your chance, 4.26%, set against the 28.57% price gives -24.32 points and a fold. With a $100 pot, a $66.67 call and no more betting, the average value of the call is -$56.74.

### At what count of outs does a two-thirds-pot bet on the flop become a call?

8 outs is the line. At 8 the chance is 31.45%, enough for 28.57%; one fewer gives 27.84%, which is not. Your 1 out sits 7 below it on the flop, at 4.26%.

### One card or two: which number belongs next to the 28.57% price?

Both figures are right for their own situation: 4.26% with no more betting, 2.13% when the turn brings a bet. Facing 28.57%, each one gives a fold.

## How this is computed

The chance rests on counting, not on a rule of thumb. Blank pairs: 1,035 out of 1,081; hit chance: 4.26%.

The model is deliberately simple: call everything, win everything on a hit, face no more bets, deal from 47 equally likely unseen cards, and ignore an opponent's holding. With the price at $66.67 / $233.33 = 28.57%, later streets and shared outs are what change the real answer.
