Gutshot Straight Draws at the Flop

Gutshot (also called inside straight draws, or closed straight draws) need a single card card to complete the straight. For example, only a jack can complete the straight below:

Your Cards			The Board:

Not many outs

Counting the cards that will make the straight...

There are four helpful cards (the jacks) left in the deck.

Multiply four (outs) by four and you learn you have a 16% chance of hitting the straight by the river.

Multiply four (outs) by two point two and you have a 9% chance of hitting the straight on the next card.

You need a Big Pot

As a result of drawing so thin, you need a large pot to justify any call you might make.

When should you call?

Tilted Donkey's Pot Size Rule

If the size of the bet is $1, for example.

the size of the pot needed to break even =

(100 times the size of the call) / (chances of winning the pot)

= ($1 * 100) / 9% = 11.11

Thus the pot needs to be $11.00 or larger to make your call worthwhile.

Generalizing, you need a pot eleven times the size of the call to justify a call.

Rule of Thumb: Fold your gutshot draws.

Exceptions would be if the board is not paired and the pot is (approximately) ten times the size of the call or more. This is especially true if you also have overcards or a backdoor nut flush draw.

Never bet or raise a gutshot draw, except as a semi-bluff.
