I'm talking about the percentages that televised poker shows display preflop. I always thought it was by calculating outs and I am still sure that it has alot to do with it. But everytime I try to get the same percentage as the numbers shown on television, I dont get the same numbers.

How do you calculate winning percentages against however many people before seeing the flop? Kind of like the percentages that Phil Laak is famously known to shout out whenever he's all in preflop.

If you want to do it just based on your outs, there are a lot of charts you can find in books or online that show some combination of odds (ratio)/outs/percentage to win.

Here is one with outs, odds and percentages: pokersyte.com chart

Here is one without the odds, just outs and percentages:

Learn the basics:
Over pair vs under pair
Two over cards vs lower pocket pair
two unders vs an overpair

you'll do just fine. It's not really useful unless you can put an opponent in an exact hand which is borderline impossible most of the time.

Colin Moshman, in his book, <u>Sin 'n Go Strategy</u> , would disagree that one should limit himself to "the basics" that you give in your post.

Using a chart like those I linked to in my post (his has both ratio odds and percentages), he discusses how to think about pot odds, then he says, on page 254:

"We now suppose all factors lead to an odds-based call/fold decision. Then you should know these odds cold ."
