This is a discussion on The 24 rule within the online poker forums, in the Learning Poker section; Hello everyone! I was wondering if anyone who knows about the 24 rule can tell me if it's accurate. Do you x by 4 after

Take the number of outs you have and multiply by 2 to get the approximate percentage of hitting it with 1 card to come, multiply by 4 with 2 cards to come. For example: you hold a flush draw (9 outs), 2*9=18 so you have about 18% to hit it on the next card, or 4*9=36% to hit it on either turn or river. The real odds are 19% and 35% respectively, but this negligible error is small price to pay for fast estimates. And you don’t have to memorize a table.

In poker we rarely need to get the exact percentage, being off by a percent or two is not that big of a deal. Soloman's rule is a quick and easy way to get your chance of hitting, but realize that on the flop when you multiply your outs by 4.. you are getting the chance to hit on the next two cards,like if you were gonna call an allin or go allin. if there is gonna be more betting than you need to take that into consideration. Also if you are playing no limit than look into implied odds if you haven't already.
Here is an odds chart.. if you look at Soloman's rule and than compare those numbers to this chart of the actual percentages, than you will see it is not too far off.. 123456789.jpg

it's quite accurate up to when we have 9outs, the more outs = less accurate
You can make a simple calculation to combat this though... you subtract the # of additional outs from your final answer (< sounds confusing, lol.. I'll post a couple of examples). For 15outs (4 x 15)  (15  9) = 60  6 = 54% for 13outs (4 x 13)  (13  9) = 52  4 = 48%

re: Poker & The 24 rule
Phil Gorden has a video explaining this that is easy to find online. Kara Scott just did one recently as well.
Just make sure you aren't double counting your cards  ie if you have 9 heart outs for a flush and have 4 outs to make a straight don't count the heart twice (you now only have 3 outs to make the st8). I know it's obvious but I see people making that mistake.

this is also known as the speed/ sucker rule. It is always best to teach ones self how to do the complex math of poker without shortcuts and practice it because in the future when you are trying to calculate your fold equity in a threeway pot with a K high flush draw the math can get pretty complex. If you plan on playing for entertainment or make a living at micro, then sure, use the 24 rule and forget everything I just said. Otherwise, it's best to try to learn the simple/ basic algebra that is involved in poker that will help you to calculate more complex situations in the future. Most poker books have these simple equations in them, or you can always back order Bluff magazine because it has multiple articles written by the pro's about poker algebra. Hope this helps you. Good luck in your future poker endeavors and remember, if you start out learning simple things you will end up being a simple poker player, and complexity is the key to success in today's poker arena.

re: Poker & The 24 rule
Generally the x4 after the flop for two cards to come is quite accurate, but the 2x rule is usually out by 1 or two % so you can do what is called the 2+1 rule and just add 1%. I prefer just to memorise the odds of each number of outs tho.

I really appreciate your input about the 24 rule and looking into the bluff magazine or poker books. You sound like a smart person. Would you happen to know what poker books are good? I'm trying to learn all i can and i'm like a sponge right now when it comes to poker. My friends back home are used to "basement poker" and have no idea what i put into learning and studying poker. They showed this girl last week on Poker After Dark who is 24, and never graduated high school and has been playing poker ever since. She won several tourny's and has over 3 million in prize money. This makes me think that i have a shot too. Thanks again! Brian
