Calculating the Odds.
 
Is there a quick way to calculate odds to compare to pot odds based on number of outs I have?

At the moment, i'm doing 47/4 for four outs on the flop, but this can be tricky to work out quickly in my head.

Do you just calculate odds for each number of outs then learn by rote? Or is there a quicker way to calculate on the spot?

Thanks,

G.

I'd just type up a chart and post it by your computer, after a few thousand hands you'll have it memorized to the point where you don't need it any more.

outs times 4 on the turn
outs times 2 on the river

Quick and painless AND pretty accurate.

Thanks for the replies, i'll make up a list of outs and refer to that till i've got it.

I didn't really understand the x2 / x4 thing. How can you use that in a game?

eg : pot is 8sb, bet is 1sb. pot odds are 8-1, 4 outs is 11.8-1. How can i use the x4 thing?

if it's as % chance of getting a card, how can i compare this to the pot? bet / potsize? not sure i can do that in my head.

It's percentages.

I guess it's not easy to compare. You should memorize everything quickly enough anyway.

Picking a nit here, but it could be important in close situations. 47 cards unseen with 4 outs is actually 10.8:1 (rounded) not 11.8:1.

You can either do 47/4 = 11.75 and then remember that one of those is yours, so 10.75:1.

Or do 43/4 = 10.75:1. That's cards that don't help divided by cards that do.

yes you're right (still new to 11-1 type odds).

I hadn't spotted that, thanks. It makes a lot of diffence to the calculation.

The last thing you want to do is calculate in your head at the table. Forget about the shortcuts and just memorize them. There really aren't that many numbers to memorize and you will know them off the top of your head in no time flat.

First: You don't need to know anything above 9 outs. If you have more than 9 outs to a lock, the pot will almost always offer you the proper odds.

Second: Only memorize the odds for the next card to come. The odds for two cards to come are very misleading because you have to assume you'll be seeing BOTH the turn AND the river and the board can change dramatically when the turn is revealed.

The difference between the odds for the next card on the flop and the next card on the turn are miniscule. Forget about the difference between the two and just memorize the odds for the next card to come on the turn.

Pretty soon, you'll just know that a flush draw is 4.1 to 1.

I googled "poker odds chart" and came up with this.

Good luck!

I think under the micro limit faq there is a link to the SSHE starting hand guide. Also in that guide is a chart with odds to make, chart is for one card to come, but a little math can tell you the odds with two cards remaining.

Is it even possible to have 22 outs?

KQclubs

10J2 2 clubs

could be 21 outs... I can't think of how you could get to 22 though.
