### Mathematics of NL Hold'em: Season Premiere by WiltOnTilt

WiltOnTilt begins with a primer on the importance of math in NL Hold'em. In a classroom setting, he discusses probability and odds, variance, pot equity, and introduces us to Expected Value (EV).

#### About Mathematics of NL Hold'em

WiltOnTilt will discuss key concepts related to the mathematics of No-Limit play using Powerpoint. Begin with the basics: probability and pot odds. Then follow Wilt to more advanced arenas: implied odds and reverse implied odds, software tools and mental shortcuts for equity calculations, complex EV calculations, and an exploration of fold equity. And watch this series conclude with a discourse on the ultimate in professional poker math: hand frequencies, valuebetting, and G-bucks.

You can also calculate it by the whole pot, which might be easier in some cases.
EV = (.63 * 2000) - (.37 * 2000) = 560\$

First off all great video im a newb (just joined)
But isn't equity calculated by the effectief stacksize on the start of a hand or is this the same thing:-)

yes you'd always want to use the effective stack size

Do the odds charts you present assume that you will be all-in on the flop with two cards to come? Or all-in on the turn with one card to come? I am just wondering as I think in most flush draw cases it is not always going in on the flop depending on how deep stack sizes are, therefore wouldn't I use what my drawing odds are on the flop for just one card to come? Also, can you clarify how when you spoke of having 7 outs in reference to the odds chart that you are a 27.8% underdog to win on the flop. Isn't it really to make you hand and not to actual win? I am not trying to be nit picky, but I come from a limit background and am trying to learn a lot of no limit mathematics and apply it correctly at the table.

yes, the chart assumes seeing 1 card or 2 cards. Also yes, the # of outs to make your hand isn't always the same as the % chance of actually winning the hand, just that the most common scenarios for discussing this type of math end up being % chances to make big hands like straights and flushes and full houses that we play as if they are nutted most of the time since the times we run into flush < flush or boat < boat are very small...but you are still right that just because we hit our hand our opponent doesn't necessarily have 0% equity etc

Wouldn't an opened ended strait draw +flush draw be 17 outs? 9 for the flush and 8 for the strait draw since you can hit 2 different cards to make a strait?

don't double count the cards that make both a straight and a flush! :-)

Wouldn't that be 15 outs because if you needed any heart to make a flush and then you needed either a 5 or 8 to make a strait I see that you would subtract 1x 5 and 1x 8 because they will be the 5 and 8 of hearts but why do you subtract the third out making it 14 outs instead of 15? Thanks for the quick responses by the way.

yes 15 outs, i might have misspoke if i said 14

Hi Wilt,

I just signed up for DC and I think this video series you created is just fantastic. It looks like a lot of hard work went in to it and I really got a lot out of it.

So, I first wanted to say thank you for making this series --> Thank you

Second, I actually had a question about poker math for live play (not online -- literally sitting at a table) --> I'm trying to draw a line between live poker math needed and online poker math. I'm not capable of doing a lot of this math at the table (at least not w/o a calculator, pen, paper and extra time). Which math is essential for live play? All the videos in this series or maybe just the first couple or...? Any kind of input would be really greatly appreciated -- thank you!

well poker is poker, so online vs live the math will be the same and will be needed, but you're right there are some differences.

We wont be able to rely on any stats live. Also the pot sizes and bet sizes not being easily detectable makes some of the quick math harder. You have to be better aware of the pot size at all times.

The key of this series is really to get you thinking more in the direction of hand ranges and how your hand holds up vs the various ranges. The EV calcs in the second half of the series will be forcing you to count hand combinations, dig into poker stove, and actually think about the mechanics of what is actually happening from a math perspective. You'll need this live or online. The difference is, live players can use some extra info to push the math one way or another. For instance, if you get a good live read, what does that mean? how do we quantify it? The math (via hand combinations) will help you put some actual reasoning/logic behind "when he sits back in his chair like that, I think he's weak" -- well that statement is kinda meaningless in and of itself, but if you can use this series to help you say "when he sits back in his chair, I think he's weaker than average, so let's take out half of his set combos and 2/3 of his 2pair combos, now we're left with a range weighted more toward overpairs and draws so my hand does X vs that range"

See what I mean?

I would recommend trying to get through the whole series. I know it's boring, and there are some mistakes in there (check the threads afterwards) but I think it will all help you get into thinking about all situations better. Then, since you don't have the stats and numbers right in front of you, you will have to fudge it a bit more at the table... but the key is going through the thought process over and over so it becomes more ingrained.

Hi Wilt,

I really want to thank you for responding -- you're a famous poker pro and it really was a bit of an honor that you wrote a response (and a very prompt one at that) to my question.

I guess I was (shamefully) hoping to cheat portions of the math a bit. But, with a bit of hard work and studying I can hopefully achieve a better mental status with the math. I went down fighting over the ratio's cause Rule 2/4 seemed so much easier. I bit the bullet, studied the ratios, and now love them and use them exclusively. I'll apply the same study/work ethic here and try to make me/DC proud with mathematical achievements.

Thank you for the thoughtful, well-written response (it wasn't just a "yes"/"no" -- it looks like you really took out the time to think about my question and meaningfully respond).

Greatly appreciated,
HB

Excellent work, you explain things very well. Most of this particular episode is review to me, but even so I gleaned some nice tidbits that help with faster calculations.

I would recommend this series to anyone.
