The Hand Lab

Set the scene, play a completely random hand against a live opponent range, then get every decision analyzed — the right play and why, with the equity math shown.

Set the Scenario

Your cards:

Tournament Chart — What the Lab Grades With

T1 — any seat T2 — MP or later T3 — CO / BTN T4 — BTN / SB steal Fold
Deep (25bb+): full poker. Open 2.2bb, 3-bet the premiums, call raises with pairs and suited broadways to hit boards. Position is everything.
Mid (11–25bb): attack mode. Your stack is a weapon — reshoving beats calling. Jam TT+, AK, AQs over opens and steal relentlessly from late seats.
Short (≤10bb): shove or fold. The only raise left is all-in — first in, jam the chart hand and put the pressure on them.
This is the exact chart the Lab uses to grade your preflop play — it follows your stack automatically and the white outline marks your selected hand. Full charts and drills on the Tournament page.

How the Lab Grades You

Your opponent is a range, not a hand. The villain is dealt real cards from a realistic range for their position and action, and plays them with strength-based logic. But your decisions are graded against their whole range — because at the table you never see their cards, and the right play is the one that wins against everything they can have.

The equity is real. Every grade comes from live Monte Carlo simulation: your hand versus the villain's current range, run hundreds of times in your browser at each decision point, compared against the price the pot is laying.

Honest simplifications: one opponent, fixed bet sizings (2/3 pot bets, 2.5x raises), heuristic villain behavior, and preflop grading based on stack-depth charts rather than a solver. The Lab trains the decisions that matter most — count the equity, respect the price, and know your stack zone.
