Quick read

The product trains two linked skills: narrowing villain correctly, then predicting how that villain reacts.

Range & React is designed for live-poker coaching. The point is not to memorize one perfect answer. The point is to build a repeatable decision process that respects villain type, scenario, action history, and range interaction.

Range Score

Range Score measures the quality of the range left after a prune. Most of the score comes from keeping hands the model thinks are likely after villain's action. The rest comes from removing hands the model thinks are unlikely.

The exact hand is still a guardrail. If the member removes the exact combo, the score is capped. Keeping the exact combo helps, but it does not automatically make the score 100 if too much junk remains.
Action Score

Action Score measures how close the member's bucket reaction reads were to the model's response probabilities. A selected response gets more credit when it is close to the bucket's most likely response.

If the top response for SDV versus a big bet is fold, but call is still a common response, choosing call can still earn partial credit. For Action Score, a small bet is 60% pot or less; a big bet is more than 60% pot.
Overall Score

Overall Score is the simple average of Range Score and Action Score. Keeping them separate is important because a player can range villains well but still miss how a specific villain type reacts.

Example: Range Score 82 and Action Score 64 gives an Overall Score of 73. The coach should not just see 73; they should see that Action Score needs the next drill.
Villain types

Villain types are one of the main signals in the product. The same board and line can mean different things from a nit, calling station, loose reg, or maniac. Coaches should use villain-specific misses to assign better reps.

Example: if a member underestimates how often a maniac raises draws, assign maniac response drills instead of generic flop work.
Coach command center

The Coach page rolls member work into pool-wide analytics, cohort comparison, assignments, flagged-hand review, and reporting. It is built to answer what a coach should do next.

Example: if Deep Stack Study Group is only 42% through its sprint and the weakest villain is Steve, the next action is a cohort nudge plus a maniac-focused drill.
Device support

Train mode is designed for desktop and laptop screens only. The range grids, table state, and postflop response matrix need enough horizontal space to be usable.

On a phone, use Results, Assignments, Account, Coach, and Admin pages. Open assigned reps from a desktop or laptop when it is time to train.
Member CSV

Coaches and admins can download one row per member with current Range Score, Action Score, Overall Score, reps done, and assignment counts. That makes external reporting easy for a coaching business.

Example: a coaching organization can export the roster before a review call and sort by overdue assignments or lowest Action Score.
