im not sure how many of you know this or not, but this would have been alot of help to me when i first started playing and didnt know the percentages.

example:

limit holdem. $1 $2 blinds. you are in the bb with
limps around to you, you opt to check it.
the flop is
you bet the flop, and get 5 callers.
turn comes the
uh oh, with 5 people in obviously you are beat. you check, and it comes back to you as bet, raise, re raise. do you call? hmmm. obviously you are beat, but what are the chances you boat on the river? oh wait, you arent good with fractions, hmmmmmmmm

well i have a solution. in order to find the % of one of your outs coming (keep in mind this is NOT the % that you win the hand)
you do this simple equasion.
known outs X chances to hit X 2
so in this example, in order to boat or better (and have presumably the best hand) you have 10 outs. one 9, three k's, three 4's, and three a's.
so the math looks like: 10<outs> X 1<chances to hit it, one river card left> X 2<i dont know why its 2, it just is>

10X2X1 ends up being 20%, which is very close to the actual number! (its actually 21%.something or other) its not EXACT, but its better than what you need to calculate proper pot odds and things.

lol..........


looks like u've found the ancient chinese secret!
put it to good use my friend!

okay lets go into a better explanation,

your OUTs time 2 (because there are ~50 cards in the deck not seen so times by 2 to get a percentage i.e out of 100) then times by how many cards till the river

50 cards in the deck??

Not including the 2 in your hand, yes.

This is how I do my rough caculations, pretty good quick way to do things though it's worth knowing the margins of error to avoid serious mistakes.

its a pretty simple method really.. if u want to see what % chance u have of improving your hand from the flop to the turn, then count ur outs and times that by 2. If u want to see ur % chance from the turn to the river, do the same thing. From the Flop to the turn (2 cards to come) do the same thing except times by 4, instead of 2.

as much as 20% = 21.7%

it is not rocket science. if you have to count your pot odds to the second decimal place they probably aren't good enough.

For the all INTENTS and purposes 20% is more than accurate enough. You need 4:1 odds. If the pot giving you 4:1 odss? Then it is profitable to call. You won't find your exact breakeven odds with this method, but you dont need to.

Good post TA.

yup. and usually the fact that you arent just going to win whats in the pot, there are also implied odds, the fact that you most likley be able to get 1 more bet, be it small out of your opponent, so that negates the small margin of error, the 1% you might be off by.

Wasn't meaning to pull anyone up on microscopic inaccuracies. Just trying to explain why the 50 cards, albeit somewhat cryptically!

I'm new here and just got a little excited about understanding something!
