There is no single strategy for IP, but one for every action by OOP. And for every action, between the different flops, OOP's range will be entirely different. So this means that essentially two variables are being varied here: The flop and OOP's range. Data with two variables is not really suitable to be displayed in a graph or table. We can decide to ignore this, and display it anyhow for later releases, however, in the current version such an option is not there. Please do note though that just clicking the "Player 2" tab will not be enough. You would also need to select for which OOP action you want to see IP's table. So this would also require a list of buttons somewhere to select the OOP action.

Hm, okay, yeah. It makes sense to me to at least include the table for IP after BB checks (since that's what's happening in the vast majority of situations after BB defends the BB OOP and a flop comes down - even when a small donking strategy is suggested by solvers people tend to simplify towards just checking 100%).

If I forced BB to *always* check the flop would I be able to see the chart for IP's strategic options then?

Yes, if OOP only has a single action then IP's strategy will be displayed.

Hi Scylla,
in GTO+, I am trying to change the river bet sizing at the end assuming all the action up to the river does not change.

Although I lock all decisions up to that point when I bring into the tree editor, make the best size update and then reload to solve, everything is back to where the whole tree needs to be solved.

Seems like this should not be necessary and the change in bet size should be a quick calculation?

Am I missing an easier way to do this?

thanks in advance.

Editing a tree will mean that a new tree is created. The solution is therefore reset. However, we can consider a variant of this where the solution is kept up until the edited decision.

Thank you for the feedback,

Scylla

Hello
I have purchased GTO+ and from the first glance it's great - its price is relatively low, its user interface seems to be very clean and its performance is OK even on a 5 y.o. laptop. The huge downside though is the lack of documentation and/or user manual. These videos on web-site are OK, but they do not even show the most recent version(e.g. "tree navigator" feature is shown in the 3rd video, but is missing in the actual software). So I am trying to figure out how to analyse the basic scenarios...let's say I played the following hand at the beginning of the tournament, so no ICM factors affect decisions.


BTN: 75 BB
SB: 75 BB
BB: 75 BB
Hero (UTG): 75 BB
UTG+1: 75 BB
MP: 75 BB (VPIP: 13.56, PFR: 14.63, 3Bet Preflop: 20.00, Hands: 60)
CO: 75 BB

7 players post ante of 0.15 BB, SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 2.55 BB) Hero has A 4

Hero raises to 2.25 BB, fold, MP calls 2.25 BB, fold, fold, fold, fold

Flop: (7.05 BB, 2 players) K 6 5
Hero bets 4 BB, MP calls 4 BB

And I would like to check with GTO+ what would be optimal play with Ax on the flop - check or bet and what would be optimal bet sizing - 1/3, 1/2, 3/4 of pot.

to do that I performed the following steps:
*entered the estimated ranges and board
* set up the following tree settings

* Run the solver

it shows the following results:


So, with most Ax hands the optimal play is to check, but if there is a backdoor draw like Ac7c, 75% bet can be done significant amount of times.

Questions:
- Are those steps done correctly for the scenario I analyse? ]Here is the gto file saved after running solver : https://drive.google.com/file/d/1yXn...ew?usp=sharing
- When the solver says, for example, "bet 60% of times but check 40% of times" - what does it mean in practice? Does it mean mixing the decision by using some random numbers generator like the clock hand?

Hey Scylla,

First off let me say that you put together a really nice piece of software. There isn't thing GTO+ can't do compared to PIO really and some are much more easier to deal with like node locking for example with GTO+.

I have 2 suggestions for you. The first one is pretty simple, when we input ranges for both players, once we click in either the Range 1 or Range 2 box, after that there isn't a way to know in which box we are. It would be simple to just put the name Range 1 or Range 2, depending in which box we are, just above the hand matrix. Also maybe specified that Range 1 is the OOP player and Range 2 is the IP player.

Second, when we look at Turn or River report and we choose the Cards Matrix to look at what might be the best Turn or River card for Villain or Hero in terms of EV or Equity, it could be nice to be able to make the choice of the Turn or River card we want directly from that matrix by clicking directly on the card we want.

Thanks.

Hey, just started having a problem with GTO+. Every time I run the solver, a box pops up that says "Checking for license" and the blue bar doesn't move. When I stop the solver, the program crashes.

I've requested a new key, so I'll see if that fixes it. Just wasn't sure if you were aware of this problem/know of a solution.

Thanks.

Edit: new key did not work

Having this problem with every single file and tree.

Hi,

I'm about to go to bed, so I will answer the other questions tomorrow. However, as for your issue, can you please upgrade to the latest version? It can be downloaded here: http://www.gtoplus.com/download/

Scylla

When next version GTO+?

It's unfortunately not possible for us to discuss time tables.

The tree navigator is definitely present in the software. I get the impression that perhaps you're not running the latest version? If not, then you can download it here: http://www.gtoplus.com/download/. The latest version is v112. Should you see a different version on the download page, then please press F5 to refresh your browser.


Using multiple bet sizes and then selecting the most frequent one will not always work. The fact that a certain size is chosen more often than others doesn't really mean anything. What you need to do is create multiple trees where you vary the bet size and see in which one the overall performance for the OOP player is best.

Can you please take a look at post #6823 a few pages back? This subject is discussed under "The importance of bet sizing" at the bottom. Here is a link to the savefiles: www.crevfiles.com/crev/forum/1/processed.rar. As it turns out, bet sizing is almost irrelevant. For just about any bet size a GTO solution is possible that performs about equally well as any other bet size. Another point of interest is that using multiple bet sizes does not give any significant advantage over only using single bet sizes. This is discussed at the first part of the post.

As for mixed output, indeed, yes, if you wanted to replicate the strategies from the solver exactly then you'd need some sort of random number generator to randomize your strategies. However, for practical use, the solutions from a GTO solver are more to be used as guidelines as opposed to strict instructions. Even if simplified, it's just not humanly possible to memorize these solutions. The trick is to try and find patterns to figure out how certain hand strengths are to be played in various spots.

A very minor difference between the two is that range 2 is moved slightly to the right, however, this could indeed be made a bit more clear. I'll see if I can make some changes here.

Ok, I'll take that into consideration.

Thank you for the feedback,

Scylla

General question - what's the major difference between CardRunnerEV and GTO+? When it it's recommended to use the former and the latter?

Sorry for a probably dumb question,but is it possible for GTO+ to show the optimal bet size on the flop in specific spot?

I saw in the tutorial that we can use custom settings on the flop/turn/river, as well as a default bet sizing, but can I just put ranges, choose a flop, build a tree, click "run solver" and somewhere will be shown optimal sizing according to GTO?

Hi, scylla. If i buy main key for Cardrunners before 1.1.2015, and second key after 2015, can i get one key for GTO+?

GTO+ is essentially CREV2. It contains all of the GTO functionality, as well as engine improvements and new features. CREV does still contain its EV calculator capabilities though, for which GTO+ is not specialized. We have decided to not transfer this functionality to GTO+, but keep it in CREV. By doing this, there's less moving parts that we need to keep into account when adding new things to GTO+.

A second license does not also include an upgrade. If the second key was purchased prior to 16/3/2018 though (the alpha release of GTO+) then we can exchange the second license for an upgrade, if that's what you prefer. For that please contact support.

No, the solver is used to figure out the GTO solution in whichever tree you enter. However, it's possible to figure out the optimal bet size by varying it and checking the effect on the overall performance. This is described in post #6823 a few pages back. The subject is discussed under "The importance of bet sizing" at the bottom.

As it turns out, the size of the bets is far less important than the quality of play. Just about any bet size will yield the same overall performance, as long as you're playing GTO. Another point of interest is that using multiple bet sizes does not seem to give any significant advantage over only using single bet sizes. This is discussed at the first part of the post.

Hello, Scylla.
I solved databes. How i can solve lock strategy for flop 479? So i had strategy solved startegy now. But i want change and lock. And after solve only this flop.

Double-click the tree to load it.
Edit as you see fit.
Re-run the solver.

Should you want to maintain the database, then create a separate savefile so that your original tree is not overwritten.

Hey Scylla, don't know if this is a bit of a bug or glitch or what but think I found something....

70bbe BTNvBB flop strategy for BB facing a pot-sized CBet (focus on J3 portion of the grid)



As you can see here, J3s folds 74.3% (continues w/ the J3ss FD + gutter combinations)

HOWEVER, when I filter for flop strategy = fold, this is what is displayed


As you can see here, J3s is almost 'folded' at a 100% clip...seems there's some sort of proportional misrepresentation going on here since it should only show about 3/4 of the J3s square in blue, correct?

When i lock strategy, can i choose just 1 combo?

I'm not entirely certain what you mean.
Can you elaborate a bit please?

It looks a bit odd, although it's hard to say if it's incorrect from just the screenshot.
Can you send a savefile to support please?
