Preflop Hand Equity Table: Equity Data for Common Starting Hands vs Common Ranges

Definition and Principle

Preflop Hand Equity, often shortened to equity, refers to the probability that a specific starting hand will win the pot after all community cards (flop, turn, river) are dealt when facing another hand or a range preflop. For example, AA has approximately 85% equity against a random hand, meaning that if both players go all-in and the scenario is repeated enough times, AA will win about 85% of the pot. Equity calculations are based on enumeration: computer software (such as PokerStove, Equilab, Flopzilla) iterates through all possible community card combinations and counts how often the starting hand wins.

Equity tables are compilations of this data, typically presented in matrix form showing the percentage for common starting hands (e.g., pocket pairs, suited connectors, high-low cards) against specific ranges (e.g., tight-aggressive range, jam range, calling range). These numbers are static but help players quickly assess hand strength preflop and make decisions to raise, call, or fold.

Equity Data: Common Starting Hands vs. Common Ranges

The following data is based on a standard 6-max table, using typical ranges agreed upon in the industry. Specific numbers may vary slightly depending on the software, but the trends are consistent.

1. Premium Pocket Pairs (AA, KK)

• AA vs. random hand: ~85%
• AA vs. tight-aggressive range (~15% of hands, e.g., 77+, ATs+, KQs+): ~80%
• KK vs. random hand: ~82%
• KK vs. tight-aggressive range: ~72% (because the range often includes AA, which dominates KK)

2. High Suited Broadways (AKs, AQs)

• AKs vs. tight-aggressive range: ~55% (slightly lower if it includes AA/KK)
• AQs vs. tight-aggressive range: ~48%
• AKs vs. small pocket pairs (e.g., 66-99): ~45%, because it needs to hit an A or K while the opponent may flop a set.

3. Middle and Low Pocket Pairs (TT-55)

• 77 vs. tight-aggressive raising range (15%): ~45% (as a small pair that is ahead)
• 77 vs. tight-aggressive calling range (e.g., 22+, AXs, etc.): ~52% — but note that postflop, the pair may be dominated by overcards.

4. Suited Connectors (JTs, T9s, etc.)

• JTs vs. tight-aggressive range: ~35% — though below 50%, it can still be called in deep stack situations due to high implied odds.
• T9s vs. a jam range (e.g., AK, high pairs): ~30–35%, not suitable for calling a jam.

5. Offsuit High Cards (AQo, KQo)

• AQo vs. tight-aggressive range: ~38% — much lower than the suited version and easily dominated.
• KQo vs. tight-aggressive range: ~30%, usually requiring a fold facing a 3-bet.

Practical Examples

Suppose you are in a 9-max cash game with 100bb effective stacks. You hold A♠K♠ on the CO, and the UTG player opens to 3bb. UTG's preflop opening range is typically TT+, AQ+, about 10% of hands. Your estimate for AKs equity against this range is roughly 55% (since AK flips against many hands in the range and dominates AQ, KQ). The pot is currently 4.5bb (assuming blinds 0.5/1), and you need to call 3bb. The pot odds for calling are (4.5+3)/3 = 2.5:1, requiring about 28.6% equity to break even. Your equity of 55% is well above that, so calling or raising is +EV. However, if you held A♦K♣ (offsuit), equity would drop to about 45%, still enough to call, but if facing a 3-bet, you would need to reassess.

Another example: Late in an SNG tournament, blinds 500/1000. You have 5♠5♥ in the big blind, and the small blind (chip leader) shoves 20,000. You estimate the opponent's shoving range as 22+, AXs, KQs, AJo+, about 25% of hands. Your 55 equity against this range is about 52% — essentially a coinflip. However, considering tournament bubble factors (ICM), a direct call may be negative because the risk of busting outweighs the reward of gaining chips. Even with slightly over 50% equity, folding might be correct.

Common Misconceptions

Misconception 1: High pairs are always ahead. AA is the king preflop, but postflop it can lose to flushes or straights. Equity tables show the win rate for preflop all-ins, but in actual play, all-ins are rare, and many decisions occur postflop. Additionally, KK's win rate drops sharply against ranges that include an ace.

Misconception 2: Focusing solely on equity while ignoring ranges. Equity tables must be used in conjunction with opponent ranges. For example, T9s may have 40% equity against a loose calling range, but only 30% against a jamming range. Mistakenly assuming a loose range can lead to incorrect calls.

Misconception 3: Overlooking position and stack depth. Equity tables are based on preflop all-ins, but in real games, positional advantage allows you to control the pot better postflop, improving your actual win rate beyond the equity table numbers. Similarly, in deep stacks, suited connectors have higher implied odds that equity tables cannot fully capture.

Misconception 4: Believing equity is the sole decision factor. Preflop decisions also involve pot odds, fold equity, reverse implied odds, opponent tendencies, etc. For example, calling a raise from a super-tight opponent with 22 may have sufficient equity, but postflop it's hard to realize that equity because the opponent's high pairs will continue betting, and you'll struggle to hit a set.

Summary

Preflop hand equity tables are an important tool for Texas Hold'em players, providing quantitative win rates for starting hands against common ranges. However, in practice, you must combine equity with factors such as position, stack size, opponent tendencies, and tournament stage (especially ICM in tournaments). It's recommended that players regularly use software (such as PioSOLVER, Hold'em Manager's Equity Calculator) to practice estimating equity, gradually developing intuition rather than blindly memorizing numbers. Remember, equity is just the starting point; the true art of poker lies in postflop decision-making.
