Edit: Now featured on DC! http://www.deucescracked.com/videos/1721-Moving_Beyond_Microstakes/18081-Supplemental_Materials_Multistreet_EV_Calculations

Here is the first of several videos that trace out an approach to incorporating multistreet EV calculation into your learning process in poker.

This vid looks at:

Basic EV
The shortcomings of Basic EV for examining certain types of poker situation
The reasons for betting
How we want to approach maximising EV

It's a really basic video that just lays the groundwork for the videos to come where I'll be sketching out how we use multistreet EV to get a handle on complex situations in poker... and eventually challenge our basic ideas of the reasons for betting.

This looks very cool, my current application of multistreet EV is mostly based on folding abit more OOP with made hands (medium PPs, medium pair etc) when the opponent barrels a reasonable amount.

Atleast this is my own understanding without watching the vid yet, can't really think of any other applications in my game currently.

Hey great video!

Awesome! I am a pretty maths adverse kind of guy, and having reached a sticking point with my study, i realised i needed to look at EV in more detail.

I made this thread asking about calculating fold equity, http://www.deucescracked.com/forums/8-Micro-Stakes-Online-NL/542061-Check-my-Maths and Entity has provided some equations that i have been using.

Although he uses a different method i think it comes to the same idea of your first simple EV calc example. Of course then you go into the nested EV calc, where i did become a little lost

This morning i was trying to work out different EVs of barreling a high card vs a brick on the turn given his flop calling range, and the amount of variables was overwhelming.

I guess video two will be looking at Cardrunners EV?

I'll be interested in hearing feedback to see how the approach in the videos is different...

Hey great video!

Cheers!!!

There will be a sort of Video 1.5 that will look at Flopzilla and what we can do with it.

Then yes... Vid 2 (and possibly 3 depending on how long it takes) will be all about making these concepts work for us in Cardrunners EV and how to handle the data we get out of CRev to improve our game.

I recommend checking out the first 3 videos of "Running The Streets" for more information on how nested EV calculations work.

But it's simpler than it sounds anyway...

1) You're using an EV calculation to model the flop.

2) Unfortunately one of the unknowns in that equation is your "Pot Equity".

3) I assert in the video that when there is still money behind you cannot know your "Pot Equity" without also modelling future streets.

4) What do we model future streets with?

5) Answer = Another EV calculation dedicated to modelling the turn.

6) The turn EV calculation is an equation with the unknown "Turn Pot Equity".

7) If there's still yet more money behind then you cannot know your "Turn Pot Equity" without modelling the river.

8) So... you use yet another EV calculation dedicated to modelling the river.


I) solve the river EV calc

II) use that to feed into your turn EV calc

III) solve your turn EV calc

IV) use that to feed into your flop EV calc (the one you really cared about all this time...)

V) finally solve that damn flop EV calc!

Me too!

I actually played some live pokerz over a year ago VS Shuttle...

(yeah some stellar table selection on my part obviously)

...and afterwards he was talking about Cardrunners EV (It was Stox EV back then IIRC)

I thought it was interesting but I figured it was one of those tools for the math geniuses and I wouldn't get it... so I didn't pursue it any further.

But trust me as long as you have an understanding of what you're doing and why it matters... which is what I'm trying to lay the ground work on now...then the process of using CRev is very lucid.

I think the big thing even if you aren't particularly interested in Mathematics is just having precise thinking. I see a ton of people who are just clearly being too vague and it really hurts their game. The reason I think cardrunnersEV is good for many people is because it forces you to think precisely, the tool doesn't do anything really if you aren't precise. As in you can't tell cardrunnersEV to do something vague, you have to be precise to be able to use it at all. Just thinking about the possible contingencies on the future streets is going to be hugely beneficial.

Yah absolutely.

YGPM, this is very cool.

nice vid!

This is just... wow! Such a good presentation of something this difficult I think it deserves a round of applause Keep up the great work! and hopefully you'll have a spot on the DC roster just like Blah

Thanks very much guys.

I really appreciate it.
