^ Yes, this is a typo.

The figure is just meant to demonstrate the relationships between the various quantities in the game... the players' various cutoff hands and their equities and percentiles.

The book does not say that hc equals 0.7, and I don't know where you got 0.767 either.

I mean, I see 0.7 in the paragraph below (from pg 240), but it's clearly just a hypothetical. hc is the SB's weakest calling hand, and its numerical value is different depending on the size of the bet he faces.

Re: 0.767, did you just read that off the graph with a very small ruler or something? Anyway, the graph isn't drawn to scale for any particular bet size. I generally tried to note in figures' captions when they are drawn to scale for particular bet, raise, stack sizes.

Do you mean BB defend range vs 4bet?
Ok let me try to summarize -- we're looking at a spot where BU opens, gets 3bet, 4bets, and then gets flatted by 77. We're wondering if the 77 flat can be good when the 4betting range is strong at the same time as it's bad when the 4betting range is weak.

I guess the standard thoughtprocess you're thinking about here is something like "if villain has a v strong preflop range we can setmine profitably, whereas if he has a weaker preflop range we actually do worse to see a flop with small pairs because we don't get paid when we hit"? And you're wondering if this is theoretically-sound?

So um, I can't think of anything that makes it fundamentally impossible, but seems unlikely. FWIW, my experience with equilibrium preflop strats is that they're highly mixed. I doubt there's any one cutoff pocket pair rank such that anything better is always a call whereas anything worse is always a fold, at equilibrium in that spot.

Yea it's just an approximation. I believe I've heard it called "Solomon's rule" in addition to the rule of 4 and 2.

Thanks Carlton.

Indeed. Check out the Errata doc on the book's webpage.

As others I found p. 124-125 incredibly frustrating.

1.) We look at Qs9h as the borderline shoving hand for SB. However this hand is not included in the shoving range on p. 124? It seems to have way too low equity to be included in the top 2/3?

2.) The books says BB calls with "19.23% of hands". The specified range is 21.57% (286/1326) of all holdem hands or 21.68% (255/1176) of all hands possible after the flop though. Took me some time to figure out you mean 255/1326.

3.) The quote below seems to be pretty important. Because you are encouraged to use your own scenarions but it is pretty easy to pick a scenario where all of this is hardly applicable. And then you desperately try to come up with correct results using the presented method when it is not really possible.

I mentioned this in the thread for volume 2, but you don't seem as active over there, so I'll just mention it here as well. You mentioned that you would post the errata for volume 2 after some time had passed (that was back in July or so), but I don't see a link to the errata on the webpage for volume 2 on D&B's website. Did I miss it, or is that something you are still planning on doing?

Hi Will. Do you still have the tendencytree.vis software. If so would it be possible to get to copy please? I am happy to pay for it.

Is there any good post on the equilibrium exercise in this thread? What software have you been using? Which sort of hands?

On page 115 there is this equation:

EVsb(raise-fold=EVsb(4-bet-fold)
48=38X+55(1-X)

The answer for X is given (X=7/17). But I want to know how I can solve for X myself. Anybody can help me out here? Which steps do I need to take to solve for X?

this should be helpful.

Thanks mate! Appreciate it!

Hey mickman, that software isn't publicly available for now -- sorry!

Lots of good resources for this available online, but I answered a similar question to this here:

hope that helps

hi,

tendencytree.vis software
Was this software like Cardrunnersev?

It's a program that showed up in one of my videos -- loads a hand history file and builds a tree of all lines taken with tallies of how often each one is taken and a display of hands shown down in each case and such.

wow, you aint planning to bring this software online again?
Guess have to ask guys who have it?

More importantly:

In your book you mentioned programms who can calculate strategies of our opponents and also defining an approximate decision tree and also defines players strategies.
Which programm did you mean with those statements?

Which programm does everything we want to learn from your books?
gtorb? oddsoracle? crev?

crev can define decision trees and do max-exploit calcs in some pretty limited circumstances but has no equilibrium capabilities to speak of. Holdemresources.net is limited to preflop-only situations. I'm not familiar with gtorb, but glancing at its webpage, it might be what you want. There's also the Solving Poker video series if you're interested in rolling your own.

Hey,

I was just interested because you mentioned in your books those software who are actually doing all that stuff.
obv the main problem is motivation and time and therefore a programm or software is the way to go from time and motivation perspective.
Also because most of the steps are just easy doable with software i guess wouldt you think this is a good idea to make monies?

The make things clear. From your point there are no such software who is able to do everything?

well, no publicly-available software . again, gtorb looks promising, I just don't know enough about it to vouch for it or w/e.

Just here to say that the book is awesome! the math is actually very easy to digest and I think any poker player that reads it will definitely get an edge over those who haven't.

so I put together a web version of ttvis as an exercise in learning Javascript. no guarantees that it works and no guarantees that it'll be improved any in the future . in particular, it probably only parses pokerstars tournament HHs right now. but you're welcome to try it out at http://ttvis.willtipton.com

thanks M_Acevedo!

Is this book for only HU or can i use it for 6max cashgames?
