About Hold’em

The skill that separates winning poker players from losing ones is reading equity — given the cards you can see, how often does your hand win at showdown? This drill asks you to estimate it directly, against a realistic table you don’t get to see through.

The setup

• Your 2 hole cards, face-up.
• 1 to 6 opponents, hole cards hidden — exactly like at a real table.
• 1 to 5 community cards already on the board.
• One 52-card deck — no card appears twice.

Opponents’ hole cards and any community cards still to come are drawn uniformly from the remaining deck. So the equity you should be guessing is “your hand vs N random opposing hands,” which is what every poker calculator reports.

What “equity” means here

The probability your hand is the winner at showdown, with split pots counted as fractional wins. If three players tie for best, each gets 1/3 of an equity unit. This is the standard poker definition — what every odds calculator reports.

Scoring

• Guess within ±7% of the true equity → correct.
• Anything farther off → miss.

The engine computes true equity by Monte Carlo (3,000 trials per hand). That gives a standard error around 1% — well inside the tolerance.

What you’re actually drilling

Most poker training drills decisions. This drills the input to decisions: the equity number itself. Made hands vs draws, multi-way pots, blocker effects, runner-runner outs — you can’t get good without a feel for how the cards on the table translate to a probability.
