Memorizing odds tip
 

I just wanted to add a tip for memorizing the odds of making your hand on the next card. It's approximate, so it works just as well on the flop or turn. For any number of outs (X) from 5 to 9, the odds of making your hand on the next card are about Y:1 where X+Y=13. It isn't perfect, but it's good enough for most decisions and it simplifies the memorization process. It's the way I usually remember the odds when I am playing. Hope this helps some of you.
