Odds, game theory and tournament maths, drilled until they're automatic at the table.
Which hands to play before the flop, by seat. Choose the situation, then tap your seat.
Everyone before you has folded.
Import PokerStars hands to see how your real decisions compare.
Record a live game hand by hand. Use it between hands, not during them: most card rooms don't allow phones in a hand.
Tap a player to knock them out, rename them or move the button.
Training mode for games where everyone at the table has agreed to it. Never use it online or in a card room.

Write up a hand once it's finished, straight after or at the end of the night, and get the right line explained street by street. Use it between hands only: getting advice during a hand breaks card-room rules and PokerStars' ban on real-time assistance.
Fill in what you remember and choose Save and review. Rough notes are fine. The review covers each street, the key idea and one thing to take into your next session.
Lessons built from your own hands. Each one takes a leak from your stats, teaches the idea behind it, then quizzes you on real spots you played. Rebuild them after you import more hands.
PokerStars saves every hand you play as a text file on your computer. Drop those files in after each session and this builds your stats, finds your leaks and lets you review your biggest losing hands.

Under 15 BB, most hands should be shove or fold preflop.
Once you've imported some hands, this reads your stats and biggest losing hands and tells you what to fix first.
Play random hands against computer players with different styles: some tight, some loose, some aggressive. After every decision you'll see how often a strong player takes each option, and whether your choice was the best play, a fine mixed play or a mistake.
Make your first decision to see feedback.
Enter cards like As Kd or 7h 8h 2c. Leave the villain blank to play against random hands. Use it to replay spots from your tournaments.
Monte Carlo, 30,000 deals.
Game theory starts from one idea: every bet size sets a price. That price tells you how often to defend, how often to bluff, and how often a bluff has to work.
Preflop all-in equity of every starting hand against random hands. Suited above the diagonal, offsuit below, pairs along it. Watch how suited connectors lose value and high cards hold up as the table gets bigger.
Simulated with 1,500 deals per hand, so values move by about ±1%.
In a tournament, chips aren't money. The Independent Chip Model converts stacks into prize equity, which is why you need a stronger hand to call off near the bubble or at a final table.
Ignores blinds and antes already in the pot, which lower the number a little.
Log every event, live and online. Over a few months this shows your real ROI and where you win.
You need 50–100 events before ROI means much. Tournament results swing hard.
Talk through a hand, a range or a tournament spot. The coach doesn't guess the numbers: it runs the equity calculator, the range charts and the ICM maths for you, and shows you what it ran.
For finished hands and study only. Don't use it for advice during a hand: card rooms and online sites ban real-time assistance.
