I'm interested in drills for learning PLO preflop hands.

Any opinions on the Vision GTO trainer at Run it Once versus the PLO Trainer at PLO Mastermind?

Aesthetically I prefer Vision and it's probably better for someone starting out. The leaderboard is also fun and will motivate competitive players. Personally I use PLO trainer. If you're also looking for training videos it's the better deal.

Hi Bill, if you are interested in how to play your hands preflop in PLO, we have just launched FlopHero.

It's a new tool based on our custom solver, that displays in a Matrix your whole range or specific combos based on the suit level you select.

In the example, you can check the last combos you open when your top 2 cards are AK and single suited

Hi Flophero,

What assurances do we have that your product works?

Has it been tested, against itself and against other solvers to see that you come up with the same answers? Is this data publicly available?

Hello, wazz. We fully understand your concerns regarding the accuracy of the solutions we provide. When we embarked on creating our solver, we gave a great deal of thought to this issue.

Many of the existing Omaha solutions on the market are primarily based on Monkersolver, a software that is over 6 years old and relies on small histogram tables for its PLO bucket system. It is not well optimized for handling large files.

We have invested significant effort in developing a framework to test our current abstraction method against various commonly used bucketing systems, and we have achieved excellent winrates and strong playing statistics. More detailed information on these results will be available in a future module dedicated to this topic.

However, it's important to note that this winrate is mainly achieved postflop. You can verify that the preflop frequencies in our app are quite similar to those in other publicly available solutions, especially for the initial nodes such as Open Raise ranges in a 6-player cash game.

Is there a paper you can quote that your algorithm uses as inspiration or is based on?

Dude just copy paste the answer from chat gtg

We use CFR as our main algorithm. As you probably know, there are multiple implementations with small differences. We haven't innovated here, we tried several variants of CFR (Montecarlo, weighted, Pure, CFR Plus, each of them with their own parametrization). However most of those variations of CFR were developed looking for faster convergence, but in our case we were interested in tree completion, to minimize the number of nodes without a solution, even if there was a mistake in a previous street.

Regarding abstractions, we use an in-house developed innovative system with two sets of buckets. In our benchmarks it proved to be a least 3 bb/100 better than the buckets created with M Johansson's (2013) method (KMeans / Earth mover's distance).

The other innovation that our solver has, is to use multiple sets of buckets in different parts of the tree. Instead of using a single set of buckets for the whole tree, we use finer-grained buckets (through Elbow and Sihouette statistical methods) in some places, allowing us to give better solutions on the most common spots.

To test the quality of the strategies we use exploitability metric based on LBR (Viliam Lisy 2016) which is a good metric to get the sense on when the tree has converged, but it has limitations when it comes to compare different abstractions, that's why we developed the testing framework.

However, please feel free to test our solutions and try to find any serious flaw on them. We will give away 3 months of our Elite plan to any user reporting one. Our cost and time to re-train the solutions is much lower than traditional solvers, so we will fix them easily.

When are you releasing post-flop? I want to put in my custom hands from live play, have a solver analyze it and tell me what I did wrong (and how much EV difference there was from optimal play). Will FlopHero be able to do that?

We are going to release strategies with live play blinds structure soon. You will be able to check your real hands with our app in the replayer too.

We plan to release the full postflop strategies along some more improvements in 1-2 weeks mostly.

FlopHero - is your solver based on your opponent playing "GTO"? Is there a way to modify opponent ability if there are playing exploitable? A lot of players live and die based on solvers yet assumptions are made in solvers to spit out a result which isn't necessarily the best option. Maybe they have this I'm not sure but would be cool if you could put in different opponent types as most of us are playing in games with exploitable opponents.

We assume in our solutions that all players are playing a GTO strategy. At some point in the future we could release some node-locking features if there is a demand, allowing the users to set the frequencies for a certain player. For example, setting the raise to a flop cbet to 0% or folding 30% to a cbet

I'd love to see a PLO solver that includes an ante feature—perhaps 0.5-1bb per player per hand. This would force the solver to solve for more multi-way flops.

I've trained 40k PLO hands on a different solver. But flops are almost always heads-up in training. I still struggle a lot in live play because most pots are multi-way.

Our solver supports ante games, we will release strategies for them in a near future
