In his first series for Bryan "PrimordialAA" Pellegrino walks you through how to use some basic math to solve a variety of interesting spots in HU SNGs. He'll show you how to break down your opponents ranges and how to optimally exploit them, and create maximally exploititive ranges of your own. This theory-packed video series will have something for everyone looking to analyze both their own game and the games of their opponents.

    Enjoy the second part of the new video from PrimordialAA!

    Please leave any question or comments you may have about the video below! :)
  • Bobbs


    Absolutely amazing videos.
    Its amazing to watch how you try to teach us everything.
    I really appreciate it!
  • grrgrrbla


    very very nice video! besides mers video on rofl this is the best / and most useful vid i ever saw on husngs!

    so this is how you won your prob bet against skates ? :D
  • grrgrrbla



    one question thought? your calling-range is assuming 0EV so we actually don't make/loose any money using the low end of our range, right? so would u start calling a bit tighter vs someone you think you have a big edge on?
  • PrimordialAA


    @Bobbs and grrgrrbla thanks for the nice comments guys, I really appreciate it :).

    @grrgrrbla for the second question, it's a bit of an interesting subject. If some hands in our calling range were EXACTLY 0EV, it wouldn't matter, but you almost will never have a hand that is EXACTLY at 0EV. HU SNGs are like cash in the fact that cEV = $EV, there is no ICM, just 1 payout. So your 'edge' is defined by the combination of every spot you take. So therefore passing up on a +EV spot to take a 0EV is almost never a good idea... But then again that kind of assumes you'll get infinite hands in against this person. So someone who you know will rematch you a ton, won't stop playing, I would always take any +EV spot you can get and that will maximize your winrate over time. It's an interesting subject, but I definitely advocate always taking any +EV spot you can get, and that will maximize your winrate, and should help increase your hourly too :-p. You speaking about Mer's videos brings up a good point, if you've looked into his recent E-Book you've seen him talk about the topic of like... how small mistakes that seem not to matter but occur pretty frequently, like folding a hand OOP you should be calling, would have cost him tens of thousands from that one mistake long-term. This is one of those situations, every spot that is +EV and you don't take, is costing you long term, especially if it comes up frequently (calling ranges vs reshoves in STs for example). So don't get too tied up in that 'wait for a better spot' stuff, need to focus on always making the best decision. And when you consider +0.0 vs +0.1 , +0.1 is the best decision :)

    @primordialAA: first of thanks for your detailed answer, yes i read the mers book and i get your point,

    this is a little offtopic, but how much time do you put in studying (analysing hands, making calcs like the ones in the video) in comparison to playing? something like 1:4? more or less? how much time studying in relation to playing would you recommend for a intermidiate player at te 30$s like me :D?
  • PrimordialAA


    Right now it's been far from where i'd like it to be, i've been traveling a lot, and haven't been able to play (or study) as much as i'd like. I did go to the jungleman seminar a few months ago, but that was it lately outside of coaching and some personal review.

    For someone playing $30s or so, I think 1:2 or 1:3 is a reasonable number, 1:2 probably ideal, 1 hour of study for every 2 hours of playing. This will be front-loaded of course, once your REALLY comfortable with adapting and a bunch of different spots, it can slide to 1:4+, but early on, until someone is VERY comfortable with their game in the majority of spots, i'd say 1:2 or 1:3 is the right place.

    @primordialAA: very helpful vid for learning how to adjust to ranges.
    1 question:
    Instead of calculating the exact equity like you did here i always used the SNG-Wizard and typed in different opening-/calling-ranges to see what hands i could reshove with.
    Is there a difference between these 2 methods? i assume the SNG wizard is maybe not as accurate in the ranges like the equilator is when using the "self calculated" equity needed?
    Thx for this video!
  • PrimordialAA


    to be honest SNG-Wizard was more of an ICM tool / STT players tool, and i've never used it, so unfortunately I can't really comment on it's accuracy, but it seems like for what it was created for it should be doing pretty reasonable calculations internally as you adjust the calling/jamming ranges, but I can't verify that, so i'm not 100%
  • rembrandt


    okay, thanks for the fast answer.
    i only asked cuz i simulated the 50% open and 22.8% call - situation in the wizard and it suggested me to shove with 93,7% in this spot.(when putting edge=0=
    i cant really explain myself the huge difference. maybe someone has an explanation for that!?
  • z4tz


    @10 I think you must have entered something wrong. I just did it and got exactly the same range as primo.
  • z4tz


    Addon, actually not the exact same handrange but very close which could be due to slight differences in how the two programs calculate.
  • z4tz


    A remark on the 10bb shove hand as well, the range you assign him is a very tight range. What happened to all the suited hands?
  • rembrandt


    you were right, i must have made a mistake. got the same now. thx
  • whiteobama


    where do i get the equilator? i just get the equilab where i cant find the features you are using
  • PrimordialAA


    It seems it was taken down, i'm looking into this for you now @whiteobama , i'll let you know as soon as I have an answer
  • grrgrrbla



    if you use equilab:
    just go to the tab "tools" and go to "handrange-equilator" and the function is the same as in equilator
  • Tim64


    Prima, just one thought on the 22-55 shove calling range. Is it fair to say that we might sometimes (reasonably) pass up a call with 67o/85s or w/e vs that narrowly defined c20bb shoving range, if we felt that we had sufficient edge vs this opponent not to take a 'slightly +EV flip'? I.e. if we assume an equal skill level vs opponent, we clearly have to call (to avoid being exploited) but once we allow ourselves an edge vs opponent, then it may become preferable to fold 85s because flipping vs 33/44 isn't as good for us as getting him to make a 10bb postflop mistake agains us. Hope makes sense. Great video anyway!
  • PrimordialAA


    @Tim64 there are a few situations, say you get an opponent open shoving every hand. First hand you get a spot you know is 50.5% but you know you won't get a rematch, this is the only chance. You should pass this spot to have a higher overall EV. However due to the nature of the blinds going up in HU SNG the frequency of how much of an edge you can gain decays very quickly. It's almost impossible to ever have passing up like a 54 or 55% spot, even if it's for your full stack, to be the right play, so people have to be VERY particular about which decisions they decide to pass up or not. Doing so even slightly too often will hurt you significantly. So some factors would be blinds (how big of an edge you can still get), Bankroll, frequency of a rematch, winrate, etc., but in most cases I would advise to take the spot. The deeper you get and the worse your opponent is, the more I would lean the other way. The deeper you are makes it matter more on how much your risking for how much an edge your gaining, and your looking to maximize your growth opportunity rather than your cEV per hand.

    Nice video bro, although i think there are some things not mentioned in here like although this is an ev+ reshoving range against this guy frcuencies we do not take into account that calling some of those hands is ev++. For all of the other i really enjoyed the video and might also add that people do not reshove 1010+ 20bb directly almost never therefore our ranges should be modified. Lastly the one you mention about 22;55 i think villains might some time openshove weaker aces(a2o, a5o) and the amount of combos of offsuit aces might totally change the calling range(have not run the math yet). But great stuff and looking forward for the next video. :)
