The wait is over for Heads-Up specialists. PLO Mastermind has just dropped a massive PLO Trainer Update that fundamentally changes how 4-Card PLO Heads-Up (HU) players study the game.
For years, studying Heads-Up Pot Limit Omaha required either a supercomputer running private MonkerSolver sims or relying on limited, generic subsets in cloud tools. That era ends today. The latest update to the PLO Trainer GTO Solver brings the full 1755 flop subset to the cloud for 100bb stacks, effectively “solving” the format for standard play.
If you are grinding HU PLO or deep-stacked 6-Max cash games, here is why this update is a mandatory upgrade for your lab.
4-Card PLO Heads-Up: The Game is “Solved”
The headline feature of this PLO Trainer Update is the sheer density of data now available for 4-Card PLO Heads-Up. The team has uploaded the complete “1755 subset”, a collection of strategically distinct flops that cover every possible board texture variance in the game.
This isn’t just about having more flops; it’s about having all the relevant ones.
- 100bb Deep Dive: You now have access to the full 1755 flop subset for Single Raised Pots (SRP), 3-Bet Pots (3BP), and 4-Bet Pots (4BP). This level of granularity allows you to drill specific texture shifts (e.g., paired rainbow vs. monotone) with absolute precision.
- 200bb & 50bb Refinements: The update isn’t limited to 100bb. New SRP flops have been added for deep-stack (200bb) play, and missing turns have been filled in for 50bb and 100bb scenarios in both SRP and 3-Bet pots.
For the HU specialist, this eliminates the need for expensive private server rentals. The answers are now instant and browser-based.
6-Max Deep Stack Additions (200bb)
While the Heads-Up content takes the spotlight, 6-Max players also get a significant boost, particularly for deep-stacked play where mistakes are most expensive.
This PLO Trainer Update adds a raft of new Turn and River solutions for 200bb 3-Bet Pots. Specifically, the coverage has been expanded for:
- Small Blind vs. Early Position/Button
- Button vs. Cutoff/Early Position
Deep stack PLO is often where the biggest edges are found, as the complexity of the game tree expands exponentially on later streets. These new solutions allow you to navigate the river with confidence when playing for 200bb stacks, ensuring you aren’t folding the winner or bluffing into the nuts in high-SPR scenarios.
5-Card PLO Refinements
The 5-Card PLO library continues to grow as well. This patch addresses specific complex nodes in 100bb Single Raised Pots (SRP):
- OOP Fixes: New solutions for Unpaired Twotoned flops (specifically the Check-Bet-Call-Flush line) and new turn transitions for Flop C-Bet-Raise-Call lines.
- IP Fixes: Fixed turns for Unpaired boards (C-Bet-Raise-Call-Paired).
These are subtle but critical fixes for high-frequency spots in the 5-Card game.
Conclusion
This PLO Trainer Update solidifies PLO Mastermind as the undisputed leader in commercial PLO solver technology. By bringing the full 1755 subset to the cloud, they have democratized high-level Heads-Up study.
Whether you are battling for stacks in the HU streets or navigating deep 6-Max games, the data you need is now just a click away.
