Interactive Learn Lab

Three hands-on tools that teach the exact math the in-game coach uses: a color-coded starting-hand chart, a live outs & pot-odds calculator, and a preflop decision quiz that scores you against basic strategy. Everything runs in your browser — no sign-up, no server.

🎯 Starting-Hand Range Chart

All 169 starting hands, colored by their Chen Formula score. Pairs run down the diagonal, suited hands sit above it, offsuit below. Hover or tap any cell for its score and which positions can open-raise it.

🧮 Outs & Pot-Odds Calculator

Pick your draw (or set outs directly), enter the pot and the bet you're facing, and see whether the price is right. Uses the Rule of 4 & 2 for equity — the same method the live coach applies at the table.

🃏 Preflop Decision Quiz

A random spot every time: your two cards, your seat, and the action in front of you. Pick the play — the quiz grades it against the Chen-formula baseline and explains why.
