# Preflop Hand Comparisons

To get an idea of the value of a Texas holdem hand, you need to know how it would stand up against other hands. Preflop pot odds calculations can be pretty easy but you still need a factor to weigh against those odds. This often leads to tough decisions in the blind positions whether a bad hand is worth calling a raise because of the odds offered. Below are a list of the common groupings of hands versus other hands along with the percentage so your have a better idea of when to call with garbage. The percentages expressed are the chance of one hand winning against another if they go all the way to the showdown.

## Pair versus Pair

80% vs. 20% in favor of the bigger pair. It varies based on distance from each other (because then they interfere with straight-making). If they are close (AA vs. KK), it gives strength to the higher pocket pair. Having the similar suits also gives strength to the higher pocket pair.

## Pair versus Two Overcards

This is your typical coin flip situation, typically 55% vs. 45% in favor of the pocket pair. Note a hand like Jack-Ten suited against a small pocket pair (55 or lower) actually has the edge because the pair does not interfere with Jack-Ten's straight making ability.

## Pair versus Two Undercards

Around 80% to 20% in favor of the pocket pair. The undercards vary between 14% and 23%. It's based on the suits and if the two overcards interfere with their ability to make a straight.

## Pair versus Overcard/Undercard

About 70% to 30% in favor of the pocket pair. It also helps the over/under hand by 1% or so if it is a low ace (five or lower) in those cases where the pocket pair doesn't interfere with a straight.

## Pair versus Same Card and One Over

Almost the same as the above scenario, it's 70%-30% to 65%-35% in favor of the pocket pair. The pocket pair's advantage can end up as low as 60% if it's against middle-suited connectors.

## Pocket Pair versus Same Card and One Under

This is the worst situation you can be in: super dominated. It's around a 85% to 15% chance in favor of the pocket pair. Even if the pocket pair is up against a suited connector, it is at best 80% to 20%. The absolute worst case scenario in holdem is the example, where K2o is 22-1 to win!

## Overcards versus Undercards

This one often surprises new players. It's typically 65% to 35%. If the unders are significantly far enough away from the overs and suited (and without matching any overcard suits), it can reduce the advantage to as little as 60% to 40%.

## Over/Under versus Two In-Between

This is usually around 60%-40% in favor of the overcard/undercard. It can reduce the advantage to 52% to 48% with a middle-suited connectors that don't share a suit with the over/under and where there is no straight interference. Something like A2o vs 89s.

## Alternating (High/3rd versus Low/2nd)

Varies from a 70%-30% to a 60%-40% advantage for the 1st/3rd hand but mostly just falls around a typical 2 to 1 edge to the player with the highest card.

## Dominated

Usually the person with the higher kicker wins 2 out of every 3 times or better, but as the kickers get lower, the edge starts to disappear because of split pot possibilities.

## Same Low Card

The dominated hand has around 40% at best if it is a suited connector against two unsuited cards without poor straight potential. Otherwise it's 2 to 1 in favor of the higher hand. If the low cards are really low (A3 vs. A2), there is a significant chance of a split pot, which would give an edge to the dominated hand.

## Tied

If it is suited versus offsuit like the example, then the suited cards gain a 2.5% edge or so. In any other case, it'll be...um...50%-50%, believe it or not. Pair against pair or other match-ups without similar suits are each 2.17% to win (the chance of a flushy board), with a 95.65% chance of a tie.
