Real Time Solving - River

Real Time Solving is one of FlopHero’s most powerful features for river analysis. Instead of relying on pre-solved databases, it calculates GTO strategy on the spot for any river card you choose. This gives you accurate, on-demand solutions for nearly every river scenario you’ll encounter.
For full context, see Strategies Overview.

How It Works

When you select a river card in the Strategies section, FlopHero’s solver runs instantly and computes the optimal strategy in real time.
It doesn’t retrieve results from a preset library - it actively solves the situation while you watch.

This means you can study any river, even unusual or rare runouts that most solvers skip. You are free to explore any scenario by setting it up through Game Configuration.

Speed

Real Time Solving is designed for quick feedback:

• Simple river spots solve in around 0.2 seconds.
• More complex situations (multiway pots or detailed textures) may take up to 6 seconds.

That’s fast enough for efficient study without long waits, giving you near-instant access to reliable GTO output.

That's quick enough for regular study. You're not sitting around for minutes waiting on results. You get near-instant access to the GTO river strategy you need.

Bet Sizing

At the moment, Real Time Solving uses automatic bet sizing.
The solver selects logical sizes based on board texture and stack depth, choosing from a standard set of options.

A future update will let you customize bet sizes to test how strategy changes with different sizings or to match real hands.
For now, the automatic sizing system provides strategically sound and consistent recommendations.

Accuracy

FlopHero’s river solver operates at under 0.4% exploitability — extremely low for PLO.
Exploitability measures how much extra EV a perfect opponent could gain by exploiting your strategy.
Lower numbers mean closer alignment with true GTO.

At 0.4%, even a perfect opponent would only gain 0.4% of the pot in additional EV, making these results precise enough for serious study and practical improvement.

FlopHero’s river solver achieves under 0.4% exploitability for precise and reliable analysis.

When to Use It

Real Time Solving is ideal for:

• Post-session review - Recreate river spots from your hands and compare your play to solver-perfect decisions.
• Scenario testing - Swap river cards to see how GTO adapts across different runouts.

This flexibility helps you understand how board texture and card distribution shift strategic ranges.
You can review results through the Matrix View, Range Tab, or Strength View for a complete breakdown of optimal play.

Current Limitations

Currently, Real Time Solving supports river-only decisions.
Solving for flops and turns requires significantly more computational power because of the exponential growth of the decision tree.

Even so, the river remains the most valuable street for GTO work — it’s where pots are largest and EV differences matter most.
Having instant solver access to river spots gives you a meaningful edge in post-session study and pattern recognition.

Why It Matters

Real Time Solving gives you unlimited, on-demand GTO analysis for river play.
You can evaluate real hands, experiment with new ideas, and strengthen your river decision-making faster than ever.
