    First! Very nice Vid. Some Vid about 4betting would be cool!

    The first 4 mins look good lol. #mustgetgold

    Really like the video because it gives a lot of material to think about and pointers on how to work on our game off table. Great way to create dynamic ranges to play optimal vs diff kind of players.
    A nice follow up would be a video with reviewed hands where you apply some of this theory in clearly profitable spots but also some marginal spots.

    Very interesting again! Especially the graphs showing on how many flops one got a sufficient equity to continue. Could you provide us with an additional value - namely small to medium offsuited Kings like K6o? Would be very helpful for me to roughly know, how often I could peel at least once with this kind of hands...
    Thank you in advance!

    I think to check how to discount properly IP/OOP is to check populations winrates from each position against each open with hand in question

    I am not sure I like the idea of quesing the discounts and then making the range, one can be easily biased and make lots of mistakes.

    coz you should discount every position differently, calling an open on MP is not the same as calling on CO

    I think playing big sample with estimating discounts and then choosing in a smart way hands with +EV winrates, to either stop calling with weaker part of range or review postflop play, will be teh nutz.

    nice video anyway!:D

    the video is amazing really. How well you discount and how good is the playability of the hand is something which I think is lacking to the players nowadays, me included. Also the math part really makes you understand/illustrate some well known phrases like - "if he's worse i would call if not i would fold". This for example is for the realizable equity - interesting concept and it would be interesting to see how this can be mathematicized aswell.

    Look buddies, who can explain to me why he calculates the possibility of our realizing our equity by deviding Pot odds by the actual equity of our hand. I have to admit - Maths isn't eactly my forte, so i'd greatful to anyone who could make this thing clear to me! Thanks in advance!

    It's not that difficult to do on your own actually. go to, insert the ranges and click on Graph HnR (hand vs range) and you can see it for yourself.

    This is actually more of a video teaching you how to do it yourself, as opposed to "spoon-feeding" the viewer :)

    #4: Maybe I'll make one in the future, will think about that
  • mbml


    #8: yes a lot of it is not purely objective. But if you wanted it to be more quantifiable, I think it's really tough to do, you need to have a really good grasp of math and maybe run a lot of simulations non-stop.

    By doing it this way, we sacrifice accuracy for simplicity. Not saying I did it in the best possible way, because I think this was largely experimental when I did the simulations myself.
  • mbml


    #10: I suppose you are referring to the arbitrary factor I was dividing the realizable equity by?

    As stated, the number is arbitrary in nature, I kind of tested it in more common spots to see if they made sense, then extrapolate the results to less common ones. It's largely trial and error, and is probably one of the biggest weaknesses of doing the calculations the way I did.

    That's why I keep saying it's not fully quantifiable (or at least I, along with most others, lack the knowledge to fully quantify these things so we have to make guesstimates).

    i like how the numbers helps us to make a better decision and also the adjustments we make based on our skill, playability of cards and opponent.

    however i am uncomfortable with playing oop without initiative, how can i improve?

    thanks mbml.

    Good video. I guess that with large enought database we can spot leaks in our assesment for different hand groups in differents spots.
