Poker Outs – No More Cheat Sheets

One of the many things that I want to achieve as I strive to fulfil my poker potential, is a highly in-depth knowledge of the maths involved.  Being an online player for so long, I’ve just got used to taking advantage of my faceless avatar and stowed the odd cheat sheet or two just out of sight of my opponents.  The fact that I can, is however, a lame excuse for a lack of complete knowledge.

I decided last night to try and memorise my outs vs odds table to start me off.  To make sure we’re all on the same page, what I mean is for any particular number of outs, what are my odds of improving on the turn or river.   I decided that the number I should focus on (for ease of use) is what my odds are for improving on the river only.  This is ever so slightly better odds than on the turn because there is one less card in the deck.  I would normally err on the side of being conservative with estimates to make sure I stay on the right side of expected value, but in this case I think it’s balanced by the amount of times you’ll see both cards for the price of a call on the flop.

I’m now going to go through what I remember without looking at the chart.  No really, I’m not going to look.

Yup, checking that over I’ve got it spot on.  At least as spot on as I was aiming for.  As you can see I’ve rounded everything down to whole numbers, to help make it easy to remember.

You might think that I’ve done pretty well to recall all that (if you believe me), especially when I tell you that I only spent five minutes committing the numbers to memory (it actually took less time than creating that table – come on wordpress, sort out your tables).  But it actually wasn’t at all difficult.

Once I rounded everything down I pretty soon noticed that the first 6 are simple – the chance of hitting is double the number of outs.  When it gets to 7 and up it’s just double and add one.  This continues until 16 when it becomes double plus 2 and then 18 it changes to double plus 3.

So all I actually remembered is that it is double the outs plus 0, 1, 2 or 3 with the changes being at 7, 16 and 18.  That’s why it only took five minutes.  Why on earth hadn’t I done that before?

  • 1 – 6  = double
  • 7 – 15 = double + 1
  • 16 – 17 = double + 2
  • 18 up = double + 3

I think that it’s this sort of simple mnemonic that is going to be the key to unlocking the maths behind poker for me.  Maybe it could be for you too.

WordPress.com

I’m starting to get a bit annoyed with WordPress. It’s so restrictive in terms of styles and editing the page. I chose to use it because I’d already tried Blogger and got annoyed with stuff automatically changing all over the place, and wordpress.com over the .org counterpart helps to bring in some traffic. It also seems to be pretty good at filtering out the spam so it never goes live.

When I set out I was mainly interested in getting writing and figured that I could just sort out the aesthetics later.  But now every time I try to do anything mildly different I seem to find another thing that wordpress.com doesn’t let you do.  It’s like learning a new retarded language.  If I want to just bump stuff around the page a bit I know how to do that normally, but this just deletes so much attempted coding.
