What is PLO Range Explorer?

The PLO Range Explorer, formerly known as PLO Trainer Desktop App is a downloadable Windows-only software with advanced range analysis features. It includes the 4-Card PLO Trainer web app which runs in-browser and has different features.

Both apps allow for browsing and training with our PLO sims library, which you can learn more about below.

Get Access to over 1 million Pot Limit Omaha solutions. 

Play through and get instant feedback to intuitively learn how to take correct decisions in Pot Limit Omaha.

The PLO Range Explorer app can visualize ranges in different formats like strength subranges or equity subranges (we call them buckets), which allow you to more quickly recognize strategical patterns in the game. The included 4-Card PLO Trainer web app also has automated preflop and postflop categorie

PLO Trainer Bucket Chart

Range vs Range comparison

Compare range vs range strength bucket distributions. This feature allows you to visualize how often each player holds certain hand classes.


Buckets Training: Play through hands within your range and get instant feedback on your decision making. Optionally you can separate hands into strength buckets and train them separately. For example if you know you’re struggling playing Kings preflop, you can train Kings only. Same with postflop, if you know you struggle to play middle set or combo draws, “Buckets Training” allows you to train them separately and play through hundred of hand examples quickly.

Equity Buckets Training: Similarly, you can play through hands and separate them by equity. For example if you want to see how hands with marginal equity are playing in a spot, you can train these combos only.

Bucket matrix

Compare range vs range strength bucket distributions. This feature allows you to visualize how often each player holds certain hand classes.

Equity graph

Visualize how equities in play are distributed over all possible holdings. This feature makes it visible which player holds an equity and polarity advantage and by how much.

Equity Bucket Chart

Break down and visualize your range by grouping hands with similar equity. This allows you to understand quickly how equity correlates with betting actions. For example: Hands with more than 80% equity, slow play over 90% of the time.

Board overview

Lists all possible board variations for any chosen node. This feature lists all possible flops in our database and the respective action frequencies and sizing choice.

Manual Import

Import your own ranges and analyze them. Train through your own sims and get the most out of them.

Export Ranges

Export our ranges to run your simulations in your own solver. Then re-import your new results to keep working on your game.

The Balanced actions feature when ticked provides you with a balanced outcome in your training session dependent on the amount of actions.

For example if you have set up a training session where the actions are raise or fold there’ll be a 50/50 balance in the answers. Same for if you have fold/call/3bet as the actions there’ll be a 33/33/33 balance in the training session.

This feature is to avoid scenarios where you may be training Early Position in PLO 50 100bb where you have for example a 17% RFI allowing you to essentially click fold on every situation and be correct 83% of the time.

Convergence issues arise when a situation has not reached a perfect outcome; this is due to some areas of the game tree taking longer to reach a 100% outcome than others. 

These situations generally arise in deeper/rarer parts of the game tree for example facing a 3-bet and a cold call the solver tends to be the least accurate in these areas.

When coming across such a situation the best thing to do is take similar combinations or group similar hands in order to get a better understanding of the action to take.

All of our post flop sims can be accessed via the PLO 500 profile. The reason they are only available via the PLO 500 profile is due to post flop rake not changing much in the overall strategy we had to decide on one set of preflop ranges we’d use to run thousands of post flop sims for.

Similar to ‘Balanced actions’ balanced buckets will allow you to train rare buckets from your range with the idea being that using balanced training samples and results by categories will allow you to find situations you’re not playing well and are costing you the most EV.
