Poker strategy
Math first. The handful of concepts that decide whether your win rate is real or a small sample. Variance, ICM, bankroll, push-fold, hand math, the language of the game.
Understanding variance
Most players who think they're running bad are running normal. Most players who think they're crushing are short-term lucky. The math sorts both out.
ICM explained
Why the chip leader is worth less than their stack share, why the short stack is worth more, and why you should fold spots at a final table you'd snap-call in a cash game.
Bankroll management
The boring topic that decides whether you survive long enough to be lucky. The buy-in numbers, the discipline rules and the move-down trigger nobody actually pulls.
Push-fold poker
Once you're 15 big blinds deep, post-flop play doesn't matter. What matters is whether you shove the right hands. The solved framework, plus a trainer.
Hand rankings and odds
The ten ranks, the 169 starting hands, the probabilities every player should know without thinking about them. Memorise these and you don't need a calculator at the table.
