POSTED May 16, 2017

Mark Lammers aka EluSiveMark uses PIO solver to design a strategy for opening UTG or MP and facing a call by the BB. With a roughly 20% opening range, Mark designs a scenario to test different options on various board textures.

love it. i think guessing before looking at the outputs significantly improves my recall.

I'd be interested in a video like this that looks at the checkraise lines. In spots where pio checkraises way more than the average reg, what should we defend against a high freq checkraise on different boards? how does the checkraiser proceed on different turns when his flop x/r is called (high freq turn check or bet big)?

LOVED this video! definitely one of my new favorites, learned a ton and you seem to be really fluent in PIO and know what to look out for. Thanks heaps for your insight, very informative! would love more videos of these types, especially including turn strategies on various rivers, aka overbetting on non-connecting cards vs. a more "oldschool" strat.

cheers

K62s board. I think for a true fair apples to apples comparison you need to lock villains range in the original sim to be under check raising also. I don't think it's true to say your actually gaining 0.7 chips ev by using the 1/3 pot. Villains who undercheck raise probably do so vs all sizings. But yes I think we can see that ev of the multisize strategy roughly equals ev of the 1/3 pot strategy for negligible difference, I just disagree with the conclusion that it might in fact be better based on your sim results.

EluSiVeMark 7 years, 10 months ago

Partly true. I think most players will x/raise a decent amount of valuehands regardless of sizing. And vs bigger sizings they should raise less. But yeah the EV's will get closer if we lock the other sim aswell.

great video Mark, strong content here!! and its a pretty good way to look into PIO for our own excercises, I think u should more videos like this, probably better for u and for the RIO community!!!

Really enjoyed this video. Great content as always. Something new and different is always good for the community. Hope to see more videos like this in the future. Keep up the great work Mark.

Great video Mark, curious about the starting ranges, the utg range seems very loose, closer to a CO/MP range, and the BB range seems too tight, folding a9o k4s qto etc. I guess playing in tournaments I'm used to defending wider but I'm curious what you think. about the defense ranges.

I'd add that I think this is why on certain sims i.e. k62ss utg had a smaller range advantage than we would think, and why pio recommends cbetting only 67%

durantula 7 years, 10 months ago

i was gonna post the same thing. even in cash games i thought we could defend the bb wider than 24% vs that loose range you gave utg. sauce would defend most suited hands here. Q4ss, A8o etc. what are your thoughts mark?

this was a great video. one of the best ive seen and the format was awesome. I will watch every pio video by you. became a big fan. thanks for the great video

Hi Lucas,

Thanks!

I made a alias of some of the best opponents at 500. Their average openingsrange is 17,3%. So we are quite aggressive in our sim. If i look at my own results with the weaker parts of my range:

As far as defense frequency. Alias is defending 28,9% by calling. So for review purposes i have BB calling too tight.
I followed a pio preflop sim facing a 2,5x open from UTG for our calling range and removed some of the mixing for this sim.

In tournaments we often have shallower stacks and/ or antes in play which makes it so we should defend very wide OOP.

I don't think folding or calling these hands makes a huge difference either way in a cg.

@ daruntula:
Thanks for the nice words.
And as far as Sauce: If he can make a hand profitable doesn't mean that we can do it. He can maybe realize 3-10% more OOP which makes those hands go over the threshold where others might not.

Hey, Mark! Thank you so much!

I've facing a little doubt about how I should approach the equity.

What's the importance of defining our equity?
I mean, how does it affect the way should we build our cbet strategy?
i.e. if we have 60+ we usually do X. Can we generalize something like that?
If yes, which typology would you suggest to use?

60% = strongg
between 50~60 = middle
etc

Thanks!

YW guilis,

Some general guidelines:
Equity advantage + nutadvantage -> much small flopbetting -> polarizing turn with bigger bets and checks (bigger bets are mixed between 2/3 and larger)
Equity advantage similair nutadvantage -> Still quite a bit of betting otf for a small size. Turn we probably need to check a bit more than above and we might increase the 2/3 pot range.
Equity/nuts disadvantage: Usually oop, lots of checking, mixed in with polar x/raises.

Is 15% UTG way too tight? I looked at 17.3 % range and it seens like A10o have to be an open but KJo is a fold?
65s+ is std to open i guess to for that ope freq?
Thanks good material

Hi andreas,

UTG range depends on a lot of things.
To name the most important ones: your skill compared to the rest of the table, rakestructure and stacksizes and likelihood to get 3bet.
