Your cards · the board · everyone still in
Leave blank for preflop. Fill three for the flop, four for the turn, five for the river.
Every opponent still live in the hand needs a range or a known hand — equity drops as more of them are added, even holding the same two cards.
Creates one opponent per seat still to act behind you — blinds set to "defending," everyone else to "cold-calling" — each with a derived %, assuming you're the one who opens. Adjust any of them afterward.
