thanks for the reply!

Im still not convinced that a solver takes this somewhat abstract term of "tournament life" into account. Tournament life and playing lower variance would seem an emotional decision as apposed to an EV decision ?

Anyone else have any input ?

Thanks again !

Hi Guys i am busy transitioning to MTT's and have run into a bizarre preflop solution sold by a very well known poker player online.

This preflop sheet states that BTN 2.8x at 100bb facing SB 3b of 4x (11.2bb) 4bets less than 1%.. 40% of KK and AKs 15% of QQ and 10% AA JJ. not much else.

I find this quite bizarre especially since SB's threebet range is wide as 16-18%

I went and ran the exact sim on monker-solver and as expected monker solver gave BTN 4b much much more frequent.

I discussed this with a friend and he told me that it could be due to "tournament life".

As far as i know this is only a concept that applies to ICM conditions and not chip ev conditions as the one described above.

Is there an error in the preflop master sheet i bought online or am i no understanding the "tournament life" concept to a point where btn wants to allow sb to see a flop with almost its entire range for free ?

Thanks for reading

Hi Ben, 32 mins sb 3b Btn KJos. on AsKh9h, you opt to check. As far as i understand sb has a substantial equity advantage here. Would pure cbet here not be a reasonable or better strategy ?

I second that Diego! Chinese games = 2 of my worst downswings in 12 years in 2 years, they do indeed have that variance (and collusion! maybe more than i even believe!)

### April 14, 2019 | 7:48 p.m.

Saulo, i appreciate your replies. Thank you.

As I understood is that we are trying to achieve a given amount of ev in a strategy - if both players in a hu match played perfect gto their ev's would be net 0 over both positions, that being said they aim for an ev of 0.

If one was to be achieving a negative ev in the headsup case when aiming for the ev of 0 that would be undesirable like in the text multi-way where the sb nash losing 17bb and not 11. Here it would seem pointless to even use the nash solutions as a framework ?

### Feb. 16, 2019 | 8:48 a.m.

Surely this (the fact that sb has more opportunity to shove as a result of btn folding more) is included within the EV results? I mean the solver solved for the EV's of the entire strategy of each individual playing nash and then it solved again with sb and bb playing nash and the button not.

*posted in*NLHE: Question/discussion on multiway pots and nash equilibria - how do we approach it ?

Hello all

I have just read a post on how GTO multi-way can harm us in cases and it has disturbed my understanding/approach.

I was wondering how you guys approach multi-way scenarios with regards to study and improvement?

By considering the below information it would seem that applying/following preflop equilibrium solutions solved by a solver like monkersolver for say btn sb bb as a guide when playing with unknown opponents may in fact be **useless** ?

I have pasted the text below:

In 3-handed situations the entire premise of GTO starts to break down,

because a decrease in one of our opponents EV does not necessarily

mean an increase in ours. In fact, it is often the case that an

opponent who makes mistakes can actually decrease our EV even if we

continue to play GTO. The easiest way to see this is to start with a

simple example of a 3 handed push/fold equilibrium in a short stacked

scenario.Suppose we are 3 handed and all players have 15BB and are playing

shove/fold poker in a rake free cash game (15BB is a bit to deep for

this to be a great idea, but that doesn't matter for the sake of the

example). The equilibrium solution for this game is reasonably simple

and can be found here.Basically the button shoves about 29% of his hands, the small blind

calls with 14.5%, and the big blind over calls with a very tight range

(9.4%) and calls if the small blind folds with a wider range (14.8%).

If the button folds, then the small blind shoves a very wide range

(46%) and the big blind calls 28%.Lets assume the hero is in the small blind. If you put that scenario

into an analysis tool like CardRunnersEV (I ran CREV with a 1 million

hand monte-carlo sample which is pretty good but not perfectly

accurate, particlarly because CREV rounds to the nearest 1BB/100) you

can easily see the expected value for each player when playing the

Nash Equilibrium strategies. They are:Button EV: 19 bb / 100 (HERO) Small Blind EV: -11 bb / 100 Big Blind

EV: -8 bb / 100If all 3 players play GTO, on average each player will win 19bb / 100

in the button, lose 11bb / 100 in the small blind, and lose 8bb / 100

in the big blind, netting to 0bb / 100 break even play.Now we know from the Nash definition that if any player starts from

the Nash state (where all 3 players are playing Nash) and changes only

his own strategy, that he will reduce his EV. Lets assume that the

button is a weak tight player and does not shove nearly enough. We

know this has to decrease the buttons EV, but nothing about the

definition of a Nash Equilibrium guarantees that the button's change

in strategy won't also decrease the hero's ev.If the button only shoves: 55+, AJ+, KQ, KJs, QJs, JTs the EVs become:

Button EV: 15 bb / 100 (HERO) Small Blind EV: - 17 bb / 100 Big

Blind EV: 2 bb / 100The hero's EV is down 6bb per 100, even though he is still playing the

GTO strategy. The hero's EV decreases by more than the buttons EV,

even though the button is the player making a mistake! If you imagine

that every player plays GTO in all positions, except for the one fishy

player who is too tight on the button, what happens to the hero's

winrate? He wins 19bb / 100 on the button, loses 17bb / 100 on the

small blind, and loses 8bb / 100 on the big blind, for an average of

-2bb / 100. Playing GTO poker in 3+ way scenarios can lose money if there is a fishy player at the table who is not playing GTO.If you imagine that the Big Blind player is a smart reactive player it

can get even worse! The condition that the big blind must lose EV if

he changes his strategy away from the Nash Equilibrium strategy no

longer applies once there is a fish on the button. The Nash condition

is only relevant when ALL players are playing Nash. Now that the

button has changed his strategy, the big blind player can change his

strategy as well to increase his profit and to reduce our hero's ev.

If the BB tightens up his over-calling range he can further reduce the

hero's EV by almost another 1BB / 100 when the hero is in the small

blind.In 3-way pots with a fish a GTO strategy can lose and furthermore, a

smart reactive player can adjust his strategy to make the GTO strategy

lose even more.It is important to note that the above are not due to ICM, they appear

even in cash games. In SnG situations where ICM is a factor there are

even bigger and more obvious instances where the presence of a fish

can make a nash strategy -EV, but the fundamental issue in both cash

games and ICM cases is the same.

Using any postflop scenario that has been solved by monkersolver as a basis for learning, as if one of the players is deviating greatly it can potentially be reducing our ev drastically to achieve the opposite of what we set out when solving the scenario in the first place ?

I have been treating my multi-way solutions with monker solver the same way that i had any head-sup solutions that i had solved for.

Any discussion around the approach to multi-way scenarios would be appreciated !

Fantastic video. Probably one of the most useful for me as of recent!

How do we go about using the preflop subset of 74 flops ? Did you use that within pio ?

Thanks

3B shoving is something I didn't actually think of I guess it puts him to a decision for a large portion of his stack. But it also puts us at risk.

### Sept. 27, 2016 | 7:38 a.m.

And then fold to a 4bet shove from him?

### Sept. 27, 2016 | 7:37 a.m.

Hes definitely not opening any two cards. Hes a good reg. Whats our plan if we get 4B by him or the short stacks behind to which we would be somewhat committed. If we fold it feels like a waste of a hand?

### Sept. 22, 2016 | 4:33 p.m.

I'm posting this from memory so just gonna round.

Payout structure is top heavy. 7 left.

1st -70k

2nd-40k

3rd-26k

4th-18k

5th-15k

6th-12k

7th-10k

Very soft table with only 1 good reg and 1 weak reg. The rest are all recs over the age of 40.

There are two <15bb stacks who are both overly tight recs.

I have 25bb which is average and the good reg has 60bb and is the chip leader.

Good reg opens CO to 2.25bb I am BTN with AJo.

SB has 20bb and is tight.

BB has 15BB and is very tight.

The top heavy payout structure makes me wanna 3B call, is this terrible? but the field being so soft and a few shorter stack makes me wanna flat.

How do I make this descision?

Sound quality is poor, commentary is poor, poor video.

Hey Tyler, fantastic video !

In the first hand, why is QQ a check on the river the majority of the time ?

I can understand that the betting of QJ and KK would have higher EV's than that of QQ with the parameters provided.

Is that saying that the EV of a bet with QQ is less than 0 here ? Surely not ?

Maybe i do not entirely understand what PIO is doing here ? I understand it as creating the best possible strategies, ones that yield highest EV but are closest to GTO with the parameters given.

-The fact that there might be no bluff combos available to be paired with QQ and that being the reason it is checked.. Does that mean that QQ is still a +EV bet but would just fall into the MES with these parameters ?

Thanks in advance

"I thought you said it was some well known players solved ranges not a solver?" - preflop ranges are solved via solvers like monker and pio they use massive amounts of resources, i could not compare other positions because i dont have the resources. However i could compare BTN vs SB/BB.

"should not be risking your stack preflop in marginal EV spots"

--The solver is concerned only of EV. If one decision is > than the other it will take the decision with the Higher ev. it does not take into account stack risk or tournament life as a factor only a higher value in EV.

Im only interested in equilibrium theory for study at this point. The ranges in question are meant to be optimal - these ranges were not created to exploit any pool of players specifically.

The preflop sheet is UpswingPoker and its preflop master sheet.
