The call in numbers

Your chance of 24.14% tops the 20.00% price by 4.14 points. That margin is on the side of the call.

6 out of 47 unseen cards is the shape of two overcards, and a single card hits 12.77% of the time.

  • Cost to call$33.33

With no more betting, the whole pot won on a hit and the call lost on a miss, the call gains $6.91 on average. The hit side averages $32.19, the miss side $25.29, and each dollar called returns +0.207.

Odds say the same thing. Hitting is 3.14 : 1 against, and the pot lays 4 : 1.

Do not forget your own call. Dividing the bet by the pot without it gives 25.00%, not 20.00%, and would show a margin of -0.8557 points. The bet over the starting pot, 33.33%, is worse and would show -9.1890 points.

How safe the call is

The fewest outs that still call a third-pot bet on the flop is 5. You hold 6, so you have 1 out to spare before the call flips to a fold.

Think of $28.61 as your safety room: the most you can give back after a hit, 0.86 times your call, with the call still level.

Look down the margin column to see where the draw stops paying. Every row uses 6 outs on the flop and a bet of a different size.

A bet larger than 0.47 times the pot ($46.69 on a $100 pot) asks for more than 24.14%. For this draw, 3 of the 12 sizes are calls.

How this is computed

The chance to hit is the exact closed form, with no simulation. From the flop, 820 of the 1,081 possible pairs of unseen cards hold no out, so the chance is 1 minus 820 / 1,081, which is 24.14%.

Read the verdict with its limits in mind. The call is the full bet, so the break-even equity is $33.33 / $166.67 = 20.00%. A hit takes the whole pot, no later betting happens, and the 47 unseen cards are all equally likely, with none removed for an opponent's cards.

Questions

Does the math favor calling a third-pot bet with 6 outs on the flop?

The verdict is call. Your chance is 24.14% and the price is 20.00%, which leaves +4.14 points. On a $100 pot with a $33.33 bet, calling is worth +$6.91 on average if the whole pot is won on a hit and nothing more is bet.

How strong must a draw be to call a third-pot bet on the flop?

The threshold is 5 outs. It gives 20.35%, clearing 20.00%, whereas 4 gives only 16.47%. Holding 6 puts you 1 above it, with a chance of 24.14%.

When is the next-card chance the better comparison?

Count two cards, 24.14%, when the bet is the last money going in, and one card, 12.77%, when the next street brings another bet. At a price of 20.00%, the two numbers give a call and a fold.
