Hello Bellatrix, I just watched the first two videos of your great series and maybe Iam total braindead or just blind, but is there a thread with the solutions to the homework of your videos or where the homework is discussed?

There was a discussion group started here:
http://www.deucescracked.com/forums/28-Secret-HQ/topics/365481-Maths-Attacks-Study-Group
but I don't know the status of it or how many people are in actuality discussing over skype, etc.
I hope others could help you, for any questions you have.

Hmmmh looks like there is not much going on and I must say your homeworks are pretty tough and screwing my brain.I made a Quiz of the Chen on Ankenman book a year ago and I could solve the most of my Quiz, but your homeworks are a little harder or Iam just out of training. Iam just interested in the numbers of the solutions, not in the way how to solve them. Because I think I could figure it out on my own how to solve them, if I would have the correct numbers of the solutions. (I would just try until I have the right solutions) I think it is way to rude to ask you for the whole equations, if you didn't already did them, so I just ask for the outcomes of the equations, not for the equations itself. Do you have them and would you offer them to us? But I guess you don't have them Frown But I will not ask you to spend your time and solve them for just a few users. Besides that nice that you have some old Deutsche Mark bills, this brought tears to my eyes Wink All the best

Oh, I have the solutions, don't worry. Wink
Send something in, don't be shy, I will send something back. I owe a couple of solutions, because they are on my other computer, so they might take a few days, but I have solutions to all homeworks as I worked on them myself when making up the homeworks Smile

Again, yes they are way harder and are extra credit for those wanting to go beyond the book. Absolutely not necessary, but I thought for the people that were really interested it would be nice to have something extra beyond the subject of the book.

This is a college level course. You can expect to spend a fair time on it. I am not even sure it will make you that better of a poker player, but for sure it will make you understand the workings behind the reasonings of many things that are hailed as gospel or common practice in training videos.

that is great. I think I can handle most of them by myself. I must say I was really bad at mathematics, so I have no german Abitur because of this. I just didn't know what I have to calculate first + or * haha. I had to start at mathematics of the fifth class. lol and I worked it all out on my own and finally could understand the mathematics in the book. After that I taught myself to write skripts for matlab clon Octave. So I now have nice skripts to every sort of EV, Probability, Equity equations which help to do the math in a quick time. So Iam somekind proud of me. But that is the reason I am so unsure in mathematics without solutions. I guess the next thing I should learn by myself is proper english, haha. Have a nice time.

man I forgot my message. To all you math teachers out there. Teach the maths with joy and fun. I really have envolved interests in mathematical problems and the strange stuff behind it. I think all the topics like prime numbers, Riemann Zeta function, Bayes theorem the teachings by Gödel are so much fun and thrilling. It is just sad that all my math teachers had this boring and dry approach to teaching and were unable to bring joy to the mathematics for the children.

Oh boy ... chapter 14. How I hate this chapter !
This is where I dropped off the book the first time I tried reading it. Too many things seem to be way over my head and too many assumptions that I don't understand.

The second time around, even with the help of "Math Attacks", it looks like it's not going to be much better. The good news for me, is that apparently, our math wizard also had some trouble with this chapter.

So I'm not going to give up just yet. Back to my notepad, book and Bellatrix's video ! Wish me luck.

Yep, as I said in the beginning, not my favorite chapter.

I really hope I didn't go to fast. I tried hard to do the steps slowly, but I can see how in the latter part of the [0,1] game it might have seemed mumbled. I really hope that you understood the deduction of the NL AKQ game?

Did you ever take analysis in high school? It may be that your problem comes with finding the derivative? I think this is also why you skipped that problem on Homework 12?

Again, the thing with the integral really isn't that important + they *really* explained it bad, it isn't needed to find out the bluffing function y(s). It's more that you understand how the size of the bet changes with the strength of your hand.

The end of the [0,1] game is blowing my mind right now.
As for the NL AKQ game, I think I got it (after 100 trials), except for the part where you say we should bluff alpha = 29% of the pot.

Yes I did take analysis in school, but that was more than 20 years ago (yeah I know ... I'm old for a poker player Frown ).
For homework 12, I did do the derivative, but maybe I messed it up ... I'll have to compare with the "answers".

Bluff alpha = 29% of the pot ?
This would make us immediately exploitable by X.

My understanding is that we should bluff 41% of the pot with nut hands (A) and bluffs (Q). The quantity of bluff hands should be equal to 29% of our value hands.

Why is k a constant because it's based on X's point of view ?
For me, "k = y - x(s) - sx(s)" = the EV for Y of value-betting a "y" hand when X's calling threshold is x(s).
I don't understand why this EV is a constant. For me, it's clearly a number depending on the value of y.

Wait, I only got your Excel file, where you calculated the second part of the exercise. Did I not receive the full homework? Were the answers not clear? Frown

Oh man, see why it is good when you guys look over my videos. The FREQUENCY of bluffing is 29% (!) or alpha, which is dependent on the bet size, but not 29% of the pot, of course (duh, me!).
We should still bet 0.414 or 41% of the pot in ALL cases.
So sorry about that mistake!

Yeah, I can't really explain it well, because I didn't understand it that well myself. It's just that when Y bets, the amount is set, he will always bet the optimal amount and that amount is like "set", which is why it is a constant.
But I know that is a lame explanation, so perhaps the best answer is: I can't explain it Frown
