Our suite covers the full spectrum of poker math: equity calculation via Monte Carlo simulation, pot odds and implied odds, outs counting with Rule of 2 and 4, and variance simulation over thousands of sessions.

Understanding Poker Equity and Win Percentages

Poker equity represents your share of the pot based on your probability of winning at showdown. When you hold AA preflop against KK, your 82% equity means you'll win roughly 4 out of 5 times. But equity shifts dramatically on every street — a hand with 20% on the flop can spike to 100% on the river.

Pot Odds, Implied Odds, and Profitable Calls

Pot odds compare what you risk to what you can win. Getting 3:1 means you need just 25% equity to break even. Implied odds extend this by factoring in future bets you'll win when you hit — making some seemingly unprofitable calls correct with deep stacks and hidden draws.

Poker Tournament Strategy — ICM and Push/Fold

Tournament poker adds layers of complexity absent from cash games. The ICM model proves that chips have diminishing marginal value — the first chip you win is worth more than the last. This means correct tournament play often requires folding hands you'd never fold in a cash game.

ICM and Bubble Factor Explained

Near the money bubble or at final tables, ICM pressure is highest. Busting costs you real equity in the prize pool, so survival has tangible value. A hand like AKo that's a clear shove in a cash game can become a fold when a short stack is about to bust and guarantee you a pay jump.

Range Construction for Every Position

Profitable poker starts with solid preflop ranges. Under the gun, you should open roughly 15% of hands. On the button, that expands to 40-50%. Our range builder provides GTO presets for every position and lets you customize ranges for different table dynamics.

Poker Bankroll Management and Variance

Even the best poker players experience extended losing streaks. Proper bankroll management ensures you survive these inevitable downswings without going broke. The math is simple but discipline is hard.

Cash Game vs Tournament Bankroll Requirements

Cash game players need 20-30 buy-ins due to lower variance. Tournament players need 100-200 buy-ins because of high variance and infrequent cashes. Spin & Go players face the most extreme swings and should maintain 150-300 buy-ins. Our variance simulator shows exactly why.

Understanding and Surviving Downswings

A winning player with a 5bb/100 win rate and standard 80bb/100 deviation can easily lose 30+ buy-ins over 50,000 hands. This isn't bad luck — it's mathematics. Knowing this in advance prevents tilt, premature stake moves, and quitting when you're actually a long-term winner.

Poker Math Fundamentals — EV, Outs, and Probability

Every profitable poker decision reduces to expected value (EV). If a play makes money on average over infinite repetitions, it's +EV — do it regardless of the immediate outcome. Our outs calculator and pot odds tool help you identify +EV plays at the table.
