Aces up is a two pair hand where one of the pairs is aces, the highest possible pair in poker. It’s written as “aces and [other pair]” or simply “aces up,” and it beats any other two pair combination except when both players have aces up (then the second pair determines the winner).
In poker hand rankings, aces up sits in a peculiar spot. It’s the strongest possible two pair, yet it often feels vulnerable because it loses to any set, straight, flush, or better hand. The term originated from home games where players would announce their hands verbally, and “aces up” became shorthand for “two pair, aces high.” While modern players might say “aces and eights” to be more specific, the classic “aces up” remains widely understood at any poker table. The hand appears roughly once every 20 deals when you hold an ace, making it common enough to master but rare enough to generate action.
Where Does Aces Up Rank?
Aces up beats all one-pair hands and all other two-pair combinations. In the two pair hierarchy, aces up reigns supreme because aces are the highest-ranking cards in poker.
Here’s how aces up stacks up against other holdings:
- Beats: Any one pair (even pocket kings), any lower two pair (kings up, queens up, etc.)
- Loses to: Three of a kind, straights, flushes, and all higher-ranked hands
- Ties with: Another aces up hand (second pair determines winner)
When two players both have aces up, the second pair acts as the first kicker. Aces and kings beats aces and queens, which beats aces and jacks, and so on.
Aces Up vs Other Two Pair: Which Wins?
The hierarchy is simple: compare the highest pair first. Since aces are the highest cards, aces up always wins against any other two pair. Kings and deuces loses to aces and deuces because aces beat kings, regardless of the second pair.

Key Takeaway
Aces up is the strongest two pair but remains vulnerable to sets and better hands. While it dominates other two-pair holdings and crushes one-pair hands, playing aces up requires careful attention to board texture and opponent tendencies. The hand is strong enough to build big pots but not invincible enough to ignore danger signs.
