Preflop Odds: The Numbers Worth Knowing

What are the most useful preflop odds?

Poker players use “preflop odds” for three different numbers. The first is the chance of being dealt a hand. The second is a hand’s showdown equity against another hand or range. The third is the pot odds offered by a bet. Mixing them produces bad calls and shaky explanations.

These figures come from counting the 1,326 possible two-card combinations. PokerStrategy publishes the full derivation and probability table. Our poker combinations guide shows why pairs have six combinations, suited hands have four, and offsuit hands have 12.

What are the common preflop all-in odds?

Matchup families are more useful than a pile of isolated percentages. You can estimate a decision quickly when you recognize pair over pair, pair against overcards, or a dominating ace. An equity calculator should handle the exact cards when the pot is large.

The values are rounded because suits can move a matchup by several points. PokerNews uses the same matchup families, including the near coin flip between ace-king and a small pair. CardPlayer’s Texas Holdem odds calculator gives exact results for chosen suits and multiway hands.

How do you calculate the chance of being dealt a hand?

Start with 1,326 possible two-card combinations. A specific pocket pair has six suit combinations, so 6 ÷ 1,326 = 0.452%. Ace-king has 16 combinations: four suited and 12 offsuit. Its probability is 16 ÷ 1,326 = 1.207%.

Average frequency never promises a schedule. You might receive AA twice in one orbit or go hundreds of hands without it. The calculation describes the long-run share of deals, which is why a dry two-hour session says nothing about whether the deck is behaving normally.

How do preflop equity and pot odds work together?

Pot odds turn a price into required equity. If a player shoves $40 into a $60 pot and action is on you, calling $40 creates a final pot of $140. Divide the $40 call by $140. You need 28.6% equity to break even before rake and any tournament considerations.

A Two Plus Two range-equity discussion demonstrates the needed step: weight your equity against each part of a range by the combinations it contains. A hand can crush the bluffs and trail the value range, so the blended number decides the call.

Tournament players must also account for payout pressure. A chip-EV call can lose prize-pool equity near a bubble or final table. The ICM strategy guide covers that adjustment. Cash-game players should account for rake when the pot is not already all in.

Why hand versus range beats hand versus hand

You rarely know both hands before the flop. If the cutoff shoves 20bb and you hold AQs, checking AQs against JJ answers only one possible matchup. The cutoff can have pairs, weaker aces, suited broadways, and bluffs. Your equity against that complete range is the useful number.

Combinations give the range its proper weight. Six combinations of JJ exist before blockers. AJo has 12, while AJs has four. If the opponent shoves every AJo combination but only half of AJs, those hands contribute 12 and two weighted combinations. A simple list of hand names hides that difference.

Start with a realistic range based on position, stack depth, prior action, and player type. Then calculate equity. Our poker equity chart explains how range equity changes when more players enter, while the push-fold chart guide covers short-stack tournament decisions.

Which preflop odds should you memorize?

Keep six anchors. A specific pocket pair arrives 0.45% of the time. Any pocket pair arrives 5.88%. Suited cards arrive 23.53%. An overpair has about 80% against a lower pair. A pair against two overcards sits near 55%. A dominated ace often has around 25% to 30%.

Those anchors catch the expensive errors. Suitedness adds value, though receiving suited cards does not make a weak hand automatic. A pair against ace-king can lose five all-ins in a row without making the original decision wrong. Pocket aces can lose despite entering as a large favorite.

Review outcomes in groups instead of judging one showdown. Mark the range you assigned, the equity you estimated, and the price you received before revealing the cards. Later, compare that estimate with a calculator. This separates a sound call that lost from a poor call that got lucky. It also reveals whether your mistake came from the matchup, the opponent’s range, or the pot-odds calculation.

Drill decisions instead of reciting percentages alone. Pick one formation, such as button versus big blind at 40bb. Review the free preflop charts, run a set of hands, and inspect every miss. The number matters when it changes a fold, call, raise, or shove.
