megaLines
Where you go once you know which spot you want to look at. The Lines map tells you which spots are worth the trip; Lines is the general-purpose tool for walking any of them, or any spot it never flagged.
1. Pick the matchup
Before any line, you fix the situation: pot type, Hero's position, the opponent's position, whether Hero was the preflop raiser or the caller, and optionally a board texture bucket. In/out of position is derived from the two positions rather than being a separate control — a hand's position order already decides who acts first postflop, so a second independent selector could contradict the first and silently filter everything out.
Pot type and the date/stake filters are the shared global filter, so narrowing here also narrows Preflop, Population, Leaks and Results. That's deliberate: one filter, applied everywhere, is the point.
2. Read the tree
The Flop decisions panel opens with the whole postflop tree for that matchup — every node that actually occurred, with its own sample size and frequencies, nested by the action that led to it. You don't build a line token by token to find something; you look at the tree and click the node you want.
3. Drill into one decision
Clicking a node drills the panel below it to that exact decision, with a breadcrumb of the line that got you there. For each available action you get its frequency, its sample size, and — when the decision is Hero's own — the range that took it, broken into 12 hand-class buckets, weakest to strongest: Air, Overcards, Gutshot, Draw, Low Pair, Middle Pair, TPWK, Draw+Pair, TPGK, Overpair, Set, 2pair+. Hover any bar for exact percentages.
Every bar is scoped to one bet-size bucket, at one node, reached via one line. A bare "Hero's range in BTN SRP" snapshot mixes hands that never faced a shared decision, which is why you'll never see one here.
Import a PioViewer aggregated report matching the node you're on and its frequencies appear beside your own, sliced by the same texture bucket — including actions the solve takes that you never do, which show as an explicit 0%. The caption underneath always says how many of the report's flops fall in the bucket, so a thin baseline can't quietly look like a strong one.
Viewing the actual hands
Click the sample-size count next to any action to open the hands behind it — hole cards, board, result and line in the list, double-click any row for the replayer. The token itself drills deeper instead, since it's already doing that job.
From the same row you can tag every hand behind an outcome in one move, or hit Train this spot to drill the decision against your own range.
