Learn the math first. Win the spots later.

Bite-sized lessons covering poker foundations — pot odds, ranges, player types, bluffing, raise-vs-call theory — plus a full tournament track (ICM, bubble play, satellite math, bounty/PKO math, final table dynamics). Each lesson has a plain-English read and a built-in practice drill, so you don't just nod along: you actually try it.

Bubble & pay-jump play

Pro

ICM pressure isn't symmetric. Who you can attack, who you can't, and the medium-stack mentality leaks that cost real money.

  • Apply the bubble attack matrix: big attacks medium, medium folds tight
  • Identify the 'bubble protector' at your table and exploit it
  • Avoid the min-cash trap that loses long-run EV

Satellite math

Pro

Where folding the nuts is correct. Equity per seat, why chip-EV breaks, and the math that makes satellites their own game.

  • Use the equity-per-seat cap to identify lock-in
  • Spot when even AA becomes a fold on the bubble
  • Switch correctly between attack mode and lock-down mode

Bounty & PKO math

Pro

Knockout tournaments have a third currency. When to call wider for the KO, why chip leaders should tighten in PKO, and the fastest-growing tournament format nobody teaches well.

  • Use the bounty-pull shortcut to widen calling ranges
  • Recognize when bounties are NOT in play (you don't cover)
  • Invert your big-stack play in PKO: tighten don't bully

Final table dynamics

Pro

Pay jumps stack up at the final 9. When chip-EV diverges hardest from real-money EV, and the spots where short stacks have leverage over big stacks.

  • Apply the FT stack hierarchy: medium = most pressure, short = least
  • Adjust to payout-curve steepness instead of one-size-fits-all 'tight'
  • Avoid the three biggest FT leaks (chip-leader ABC play, medium-stack coin-flips, short-stack laddering)

Try it on real spots

Read a lesson, then put it to work at the trainer.

Theory is cheap. The trainer drops you into randomised spots, grades your decision, and shows the EV math behind it.
