Great stuff!

Do you have any particular method for bringing your conclusions to the tables? Do you memorize particular spots and board textures, or do you have any other way?
ZenFish 11 years, 11 months ago
Very good video! For Hand 1 you build a c/r range with value and bluff combos. You can both c-bet and c/r these hands, obviously. How would you mix it up vs an unknown?
André Santos 11 years, 11 months ago
Thanks guys!

Jonna,I started by studying spots that I thought would come up pretty often and everytime I did so I made sure I made different assumptions(like diff kinds of villains,slightly drier/wetter board, or slighty bigger/lower SPR) so that I understood how much esch of this things affect decisions. After having all the "standard" spots covered I started (and keep on) studying more "unhortodox" spots. If you do this often enough you'll start getting a good grasp of the EV of your plays.

ZenFish, that's a (good) tough question. I guess mostly it depends on how i think villain will react to the diff possible actions. I decide based on specific notes/stats on villain and experience of having tried each of the two options(bet or cr in this case) many times (and thus having a good grasp of what villain will think/do). If i think villain is well balanced i'll just try to be well balanced myself and in this case you do so by never betting, or by betting a small and balanced range and check-(folding,calling,raising) the rest.
CleverNick 11 years, 11 months ago
Hi Andre, very nice video!

You conclude XR vs. wide Cb range in last hand is prior since it is +8bb but you never really estimated or calculated to EV for calling like he did. Is it just common sense that it is not +8bb to call there?

On the river you call since you don't estimate he has a flush often enough. But don't you think he would often Vb his straights here also (especially with the 4th club on the river)? Furthermore would he bluff here often enough given that the 4'th club on the river would make you call more?


André Santos 11 years, 11 months ago
Hey Nikolaj, the E.V. of calling if very hard to calculate due to the amount of variables left to calculate (different turns/rivers, different actions villain could take on future streets,etc). The way I normally do is calculate the E.V. of raising and then think how the hand would play out if I called instead of raising and try to guess whether that has a higher/lower E.V. than raising.
In this case I think that raising probably has a higher E.V. than calling if CO is cbetting really wide (like I assume he is), because by raising we're making him fold many hands that we have a lot of equity against (in fact we're almost always behind equity-wise). That, the fact that we're gonna be playing turns and rivers oop, and also the fact that we don't have a tone of implied odds w/ naked Qh FD makes raising better than calling imo.

Excellent video. Great example choices and superb ppt analysis. I've watched all cash Elite vids and other than Phil's this was top for me by a lot.
Question:
Are all those abbreviations for PPT built in or macros you defined? Such as, the $0g. I'm familiar with most but not all of those abbreviations.
Nakamator 11 years, 11 months ago
You can find them here zach. http://propokertools.com/oracle_help/range_of_hands#syntax_macros

And congratz for you first and trully solid video Andre. Looking foward to see more great content like that.
gendeLic 11 years, 11 months ago
About the last hand.... doesn't the cbet size factor in a lot? I would figure that the FE increases when potting. I mean we can protect more and we are likely ahead. On the contrary you say the board is so dry, I'm just not sure if your FE is what is with the sizing applied and therefore his c/r range is less callable....
André Santos 11 years, 11 months ago
Hi gendelic, it's true that if you cbet pot you're gonna increase your FE(you also need it to work more often). However I think if we pot we are probably giving a little bit too much info about our hand and allow our opponents to play close to perfect. Obviously you could argue we could also do this with stronger hands, however with bluffs a smaller size makes more sense.
In general in boards this dry and ip I prefer to cbet more on the smaller side (since we're gonna be bluffing often and thus want to give ourselves a good price)
pacmang 11 years, 11 months ago
Nice video. I enjoyed the format.

In the last hand where you first depict a stack off range for villain which includes almost all of the higher flush draws, his calling range now should only consists of stuff that is capped at a J or Q high flush.

Now you will obviously bet for value when you have him beat but wouldn't this hand be a great hand to bet? Given that 1. you have outs vs a flush. 2. you are still v-betting vs. some hands and denying equity. and 3. you are now making his decisions tougher by having big flushes for value and these types of hands as a bluff.

I would probably go something like (and this is for 3 streets of betting from you).

3 streets of value = good flush+
3 streets of bluff = maybe something that had outs and consists of a Ac or Kc
2 streets of betting = your hand and sets and lowest flushes and straights

please share your insight
André Santos 11 years, 11 months ago
Hey pacmang,thanks for the feedback.
I understand your point, however i think our hand is too strong to turn into a bluff and probably doesn't get called by enough worse hands to value bet. Regardless of everything else i wouldn't expect villain to fold a turned flush w/ 1.5psb left and we're not bluffing anything else. Also i think this is a good hand to have on my river call range after checking back turn.

In my opinion a better range distribution would be(if you want to be relatively well balanced)
3 streets of value: any flush
3 streets of bluff: Qc/Jc/Tc hands (since we alrdy excluded nut and 2nd nut flushes from his range)
2 streets of betting: some hands w/ one(other) club


Albin 11 years, 11 months ago
Amazing video Andre! I think you forget to include some double pair hands in your ranges but there are a so small % of hands so the result would probably be the same.

Looking forward to see more videos in Phil Galfond class from you.
André Santos 11 years, 11 months ago
Hey Albin, thank you!
I did include double pair hands in all the 3b ranges. However I might have forgotten to include them somewhere else, and if that's the case I apologise. I always try to build ranges that are as realistic as possible.
sted9000 11 years, 11 months ago
Thanks. Great Video. I am working on a spreadsheet to keep all my PPT syntax and had a question....when I was looking at some of your assumed ranges in the video at the end you tack on 8%:xxyy. Why? What kinds of hands does this throw into the mix that are not already included. Thanks.
André Santos 11 years, 11 months ago
Hey Ted, those 8%:xxyy (or 8%$ds), add most QQds, some strong JJds and other hands like AK99ds. I added that because I didn't have as much combos in that range as I wanted, but you were right in pointing that out, since there are probably better (more realistic) ways to write that range.
sted9000 11 years, 11 months ago
Just created ranges for IP 3b'er (tight med and aggressive) any thoughts?
Tight 3.8%- AA!AAA!wxyz, KK$ds, (KK$R$R)$ss, 6543+$ds, 8654+$ds, 8754+$ds, 8764+$ds, 7654+$ss, 9875+$ss
Med 7.5%- AA!(AA:wxyz), KK$ds, (KK$R$R)$ss, (KK$M$M)$ss, $0g$ds, $0g$ss, 8764+$ss, 8754+$ss, 8654+$ss, $1g$ds, $2g$ds, ($R$R$R$R)$np$ss, ($R$R$R$R)$np$ds, (****)$tp$ds, ($R$R$R$M)$np$ds, ($M$M$M$R)$np$ds, ($R$R$M$M)$np$ds, ($M$M$M$Z)$np$ds, 8%$ds
Aggressive 10%- AA!(AA:wxyz), KK$ds, (KK$R$R)$ss, (KK$M$M)$ss, QQ$ds,$0g$ds, $0g$ss, 7653+$ss, 7643+$ss, 7543+$ss, $1g$ds, $2g$ds, ($R$R$R$R)$op$ds, ($R$R$R$R)$op$ss, ($R$R$R$R)$np$ss, ($R$R$R$R)$np$ds, (****)$tp$ds, (****)$tp$ss, ($R$R$R$M)$np$ds, ($M$M$M$R)$np$ds, ($R$R$M$M)$np$ds, ($M$M$M$Z)$np$ds, 9%$ds, AKQ$ds, AKJ$ds, Ax:654+:xxyy, Ax:765+:xx

Hope you don't mind that I used your ranges from the video as a foundation.
The tight, med, and aggressive %'s are arbitrary (but I think will be useful to stereotype a lot of regs in my games).
My main concern is with the tail ends of the med and aggressive ranges.
Thanks
sted9000 11 years, 11 months ago
Agreed and maybe even in the med range as well (loose players almost for sure have them in their, because they are missing out on so much value when they get cold 4b and hold AA:wxyz).
Thanks for the syntax suggestion. I am learning this stuff as I go.
André Santos 11 years, 11 months ago
Your ranges seem pretty good to me Ted. You repeated yourself in some cases (e.g. instead of writting ($R$R$R$R)$op$ss and ($R$R$R$R)$np$ss, you could have just wrote ($R$R$R$R)$ss, but that's obviously not really important apart from saving you time.
Anyway I think it's pretty good that you're thinking about this actively and trying to build ranges yourself, and I'm glad the ranges I used for the video have helped you do it!
ZenFish 11 years, 11 months ago
Here's a tip for writing ranges more economically: Only specify the $ds combos explicitly, then wrap a final parentheses around everything and remove trips, rainbow, and four-in-a-suit. For example:

(AA, KK$ds, $R$R$R$R, 8765+)$nt:xxy
TianYuan 11 years, 11 months ago
@Ted:
I think it's a mistake to not include rainbow AA in a loose IP 3betting range, in my experience at least.
Ax:654+:xxyy seems like a very redundant way of writing it, you could just write A[654+]$ds...
sted9000 11 years, 11 months ago
Ooops...posted in wrong spot...

dontcrybaby 11 years, 11 months ago
In the hand you turned top two pairs and checked behind ending up calling the river, my question is: Will you assume he will not transform worse two pairs into a bluff and call also with AA/KK?, what about only AT or will be more hands like good QQ/JJ that he would transform?
André Santos 11 years, 11 months ago
I don't really expect him to turn worst two pair into bluff, so I guess I'd also call w/ AA. KK it's a diff situation since, one of the hands I think he might turn into bluff is KK, so I'd be a little less inclined to call. w/ AT, I'd be even less inclined to call, since I think he can turn JJ/QQ/KK into bluff. Having clubs in my hand would also be an important factor to call (especially if they're Qc/Jc/Tc, because I don't expect him to have nut/2nd nut flush often).
limpinski 11 years, 11 months ago
Very nic vid!

Small thingy:
In the second hand (3betting sb AQJTss) you do not adjust the BU range to exclude hands he will 4bet. So instead of 35% it should be 35%!(AA and whatever else you think he will 4bet). If your sb 3b range is wide enough and given him being shorter I can imagine good KK hands being in his 4b range as well. This will change outcomes.
André Santos 11 years, 11 months ago
Hey limpinski, thank you for the feedback. You're absolutey right. I wrote a open range, when what I should have written is a call to 3b range. I'm gonna redo the ranges and re-calculate the F.E., and if it's a relevantly different number I will either post it here or include it on my next video.

Edit: Did this and the difference was <1% in F.E.
Rasmus Fahrendorff 11 years, 11 months ago
Nice video!

How much time would you say you spend on studying compared to playing?
André Santos 11 years, 11 months ago
Hey Rasmus, I'm not sure I know the awnser to that question. There are times where I do a lot of studying and other times where I dedicate myself to playing only. I think putting some volume both studying and playing every week is really important to improve.
It depends on your level and what you want to accomplish, but I'd say playing about 25h/week and working on your game 6-7h/week seems like a balanced schedule to me.
Dempire 11 years, 11 months ago
Andre is there a reason you calculate a hand's eq vs S.O.R. by calculating the equity vs betting range minus the equity vs the hands that fold all given that villain does not fold? Can't you just sim the hand vs the stack off range as part of the preflop range?
André Santos 11 years, 10 months ago
Hi Chiraag, that's a good question. You definitely could just calculate the eq vs SOR by building his SOR and run the sim. The problem I see with this is that it's really hard to weight the hands on this SOR. I think by building realistic 3b ranges and then subtracting the combos of hands that you think he's not folding you're gonna have a much smaller margin of error. Also if you've built custom 3 ranges, then it's faster to do it this way than building a SOR range for each scenario (instead of just subtracting the unweighted hands that he's probably not folding from the custom 3b range)
Munchausen 11 years, 10 months ago
Confused by the first hand. You have no con-bet range on the flop. I assume that you don't think it's correct to con 0% here so I'm not sure why you are focusing on a balanced checking range when you aren't advocating a balanced range inherently since all your bets would be weak.
The exception to this would be if you actually do think checking all hands is correct here and I find that hard to believe.
Also, if you want to have a checking range it doesn't seem inherently necessary to have a x/r and x/c range. You could just have a bet and x/c range for example. As long as the x/c range is balanced with some strong hands, it is not exploitable (though it may not be theoretically optimal)
André Santos 11 years, 10 months ago
Hi Munchausen. Thanks for the feedback. There's a tone of ways you can balance your range on this spot. I stated that having a cbet range is definitely fine, but I wanted to focus only on which hands I'd be x/c and x/r assuming I never (or very rarely) would be cbetting. However it's definitely an option to include some of the hands I used on either of this ranges (x/c and x/r) and include them in my cbet range (at least some % of the time)
Munchausen 11 years, 10 months ago
In the second hand, the button has an effective open of 45 and a call of around half that. I didn't see a 4-bet %. Is this at all realistic for mid stake games, or is your sim for a particularly tight button? People who open 45 would tend to call more I think. I think the usual call % in position in mid stake games to be 75%+, meaning that the range of hands for your sim be something more like 36-40%.
André Santos 11 years, 10 months ago
I don't understand when you say that villain has a call of half of 45%. Do you mean a call to 3bet? I actually assumed he had 0% fold to 3b, or in other words the range I wrote was already his call to 3b range (altought I called it "open range"). However as you've stated (and as limpinski as stated some posts above) I forgot to exclude his 4b range from the 3b calling range (or "open range" as I called it).
When I re-did this the F.E. difference was <1%, so it ended up not being very relevant.
Nakamator 11 years, 9 months ago

Hey Andre! 

Regarding the second hand (3bet with AQJTss), I decided to recreate your simulation to experiment doing my own here and got stuck at some point. 

Using Range Explorer, I included the flop, the dead cards, and villains opening range. The table you created to represent these ranges, you get to a number of 22.54% which represents the number of hands remaining for villains range after we know the board and our hand. 

However, after putting those very same ranges I wasnt able to get to this specifc number of 22.54%. All the other data match, like hands in isolation (121673) and after board/dead cards (61013). After the board and dead cards are known, we get to a 40.95% of hands after board/dead instead of 22.54%, unless I am missing something.

Could you  please double check and shed some light on this? I would like to recreate these very useful/awesome sims you did to do them myself, but I got really stuck on this number, which, as you said yourself, is very important to calculate our FE. 

Thx again for your great job and keep them up. 




André Santos 11 years, 9 months ago

Hey Diego! 

That's pretty weird, and I'm actually pretty sure it's a bug from odds oracle, because as you can notice it says "61013 hands after board/dead" which is about half of the 121673 hand combos we started with (w/ no board/dead cards). In other words there are 270725 combos of hands in PLO, and 61013 remain after we know the board and dead cards so 61013/270725=22.54% of hands. 

So I guess that's either bad wording by them or more likely a bug.

InsideMan 11 years, 9 months ago

It's not a bug. All hands in PLO after dead cards are 148995 hands. 61013/148995=40.95%. If you were to play 100% VPIP to the flop then you would hold 35%,432+,$1g,$2g,xxyy 40.95% of the time.

61013/270725 is like comparing oranges to apples. One number contains removal effects, the other doesn't, so the frequency doesn't really mean anything. 

To me it looks like the web based platform is the culprit here as they say "optimized count 61013 (22.54%)". I'll post this issue on the PPT forums to see what bachfan has to say about this. 

InsideMan 11 years, 9 months ago

Here is the link to the thread I started: http://forum.propokertools.com/showthread.php?783-Erroneous-result-in-Simulator-2.0&p=1956#post1956

Nakamator 11 years, 9 months ago

Andre, fwiw I ran the sims here. Using numbers provided by Oracle, even though they are different in terms of %, we still get to the same results. The "hands after board/dead" of his folding range ( (35%,432+,$1G,$2G,XXYY)!(K,88,44,84,876,865,875,754,654,765,76$op,75$OP,65$op) ) results in 21.58% of hands. If we divide that by 40.95% (his opening range) we get to the same 52.7% of FE needed. 

I didnt run the numbers for the others simulations tho, will do it later. 

flushbingo 11 years, 8 months ago

Any plans of more vids, this was a good one and I would love to se more. I like how u break down your plan with your range for x/c and x/r in the start.

Donkpredator 11 years, 5 months ago

at 20:30, I think its a leak not to be betting there.. A bet of 150 accomplish so much. First of all you handcuf him on the river, and 2nd of all you protect your hand which is very vulnerable. Its just a better play with your range imo. 

Festivus 11 years, 2 months ago

Great video. One of the best i have seen.

But @20:40 do you really think he

opens all these 6543, 7654, A432ds, A543ds, 5432ds

from MP and calls a 3-bet?

Personally i wouldnt consider opening any of these hands

exept maybe 7654ds. On the other hand thats only 620 hands in total

and i assume wouldnt change your numbers much.

André Santos 11 years, 2 months ago

Hey,

Thanks!

I think 7654r and 6543r might be (open-)folds, but personally I would always open 7654$ss,6543$ss and the other low rundowns double suited in most line ups (exception would be maybe when co/bt are super tough and we're playing very very deep). Opening this kind of hands is somewhat important for your range balance (or in other words they have good implied odds because villain knows you don't nail low flops very often).

I should have wrote (7654,6543):xx to exclude the rainbow hands, but it won't change significantly the results.
