The 60-second tour

From the Study landing to a per-combo postflop drilldown in six clicks.

Open /study — the preflop tree

The landing screen is the preflop explorer. The Solutions strip at the top reads MTT · ChipEV · 8 players · Symmetric · 100bb — the solved regime, with every unsolved axis (Cash, ICM, other table sizes, asymmetric stacks) visible but locked. Hit Change to open the stack ladder and pick any of the ten depths from 100bb down to 10bb; each row shows how many decision points ("situations") that tree contains.

Walk a line

The position strip shows all eight seats in table order — UTG through BB — with the seat to act outlined in green. Each actionable card lists that seat's options with sizes and range-wide frequencies (most aggressive on top, fold at the bottom). Click any action to take it; you can also click a later seat's action directly and the folds in between are implied for you.

Every step lands in the URL (/study?depth=100&line=fold-r2.5-...), so any node is a shareable link. The breadcrumb above the strip replays the line — Root › UTG Raise 2.5 › BTN Call › … — and every step is re-openable.

Read the strategy chart

Below the strip, the 13×13 chart shows the acting seat's strategy for all 169 hand classes, with Strategy / Ranges / Breakdown tabs. Colors are consistent product-wide: blue folds, green calls/checks, and a red family for raises that darkens with sizing escalation.

Close the betting

When a line ends, the terminal panel says exactly what happened: a fold ends the hand ("UTG wins 2.46bb"), a multiway flop states that only heads-up pots are covered, an all-in call becomes a runout with no decisions left — and a heads-up flop shows the postflop bridge.

Cross the bridge — "View flops"

If the heads-up spot is served, the bridge card turns green: pot, effective stack, SPR, and a View flops → button into the postflop family. If it is not served yet, the card states the honest coverage level — solved (backbone solves exist, pack not shipped), library (ranges known, postflop not solved), or none.

Drill into a board

The family view lists all 184 canonical flops with texture filters and a root-action mini-bar per board. Click one to open the strategy browser: the 13×13 mixed-strategy matrix, per-combo drilldown with EVs, combo search (AhKs, AKo, 77), and the pot-odds/MDF readout. The future tree nodes are visible but locked — they arrive with the full-tree extraction campaign.

Prefer the index?

/study/library skips the tree walk and lists every solved postflop family directly, filterable by depth, preflop line, and solve tier.
