rule of 2 is great, and memorize outs:

OESD ->8 outs

gutshot->4 outs

if you have an oesd for example, you have 8 outs, then 8x2=16% is the chance a card that completes your straight will appear on a street (32% on turn & river) so 32% ~1/3...

of course if you are 16tabling you dont have time for this, and you must learn to make quick but accurate aproximations... when you play a lot you can do that as a reflex... so just keep practicing

and i remember a quote: if you are in an uncertain decision, a fold usually is the answer/isnt a big mistake

good luck!

+1!

I use this a lot too. It's only approximate, but close enough. 1 card = outs * 2, 2 cards = outs * 4.

One thing Jaime didn't mention is how to calculate the needed fold equity (which speaks for itself, but maybe a good thing to mention).

If you have 8 outs on the flop, the chance you hit your card on the turn = 8 * 2 = 16%. If you are allin on the flop the chance you hit you card on the turn or river = 8 * 4 = 32%. The true numbers are 18.18% and 34.24%.

So if you push allin on the flop, you will win 34% of the time when you are called. To make it a break even play you need to win the hand 50% of the time. So you will need a fold 50-34 = 16% of the time to break even. If your opponent folds more often, you win money.

Of course this isn't very usefull with odds because you have to convert % to odds, but it's a good thing to know

.

**EDIT: ***I just realised I might be wrong about the fold equity and it may only be true if you're allin is a pot sized bet. I'm not sure, but I have no time to think about it right now, so maybe somebody else can comment on this or I will get back at it in a few days.*
