Poker hand history review for GG and PokerStars
Bring a hand from a completed session and study it under explicit range assumptions. Viper GTO supports GG and PokerStars text histories and a manual hand-entry format.
Start free ↗Prepare a useful hand history
Use the exported text history rather than a screenshot. Check player positions, blinds, effective stacks, board cards and action sizes. Remove names or identifiers before sharing an example publicly.
For a hand recorded in a live game, enter the same details manually after the session. Missing pot contributions, an incorrect stack or an unrecorded raise can change the reconstructed spot.
Choose the street and ranges
A hand history tells you what happened, not every player’s full range. Review the proposed ranges and adjust them to the situation. Choose a supported heads-up postflop starting point; multiway pots are not covered by the two-player solver.
Starting on the turn or river reduces the remaining game tree. It also means your starting ranges are assumptions about how players reached that street.
Interpret EV loss carefully
Run the analysis and compare each mapped decision with its alternatives. The result is conditional on the chosen ranges, sizes and solver accuracy, not proof of what an opponent actually held.
Batch review can summarize supported hands by hand class. The saved-hand leak profile aggregates losses by street; an Elite-only profile by spot type is not currently part of the product.
Save only what you choose
Review scoring is unlimited. Free accounts can save 10 hands per month; Pro and Elite allow unlimited saves. Saving or importing hands uploads them to your account, while local solving itself runs on the device.
The AI coach can explain a reviewed decision within your monthly allowance. It receives the relevant hand context when requested; consult the privacy policy for details.
