You’re watching a tournament or checking the live leaderboard on your phone, and you see it next to a match: the letters AS. This simple-looking abbreviation is at the very heart of match play, the head-to-head format that makes for some of golf’s most dramatic moments. This guide will walk you through exactly what AS means, how it happens, and why understanding it is fundamental to enjoying and competing in match play.

First, A Quick Refresher on Match Play
Before we define "AS," it helps to have a solid grasp of match play itself, because it's a completely different animal than the stroke play format most of us play on a Saturday morning.
In stroke play, every shot counts toward a final, cumulative score. You're essentially competing against the entire field and the course itself. If you shoot a 78, that’s your score. Your goal is to have the lowest total score after 18 holes (or 72 holes in a professional tournament).
Match play, on the other hand, is a one-on-one duel. You are playing directly against a single opponent. The total score doesn't matter, what matters is winning individual holes. You can make a 10 on a hole, but if your opponent makes an 11, you still win that hole. The contest is broken down into 18 individual matches, one on each hole.
You win a hole by taking fewer strokes than your opponent.
You lose a hole by taking more strokes than your opponent.
You “halve” a hole by taking the same number of strokes as your opponent.
The score is kept not by total strokes, but by how many more holes one player has won than the other. If you've won two more holes than your opponent, you are "2 Up." If your opponent has won three more holes than you, you are "3 Down." This hole-by-hole battle is what leads us to our main topic.

AS stands for "All Square." It means the match is tied. Period. Neither player has a lead.
When a match is All Square, it signifies that you and your opponent have won the exact same number of holes. Think of it as a 0-0 score in soccer or a tied score in the fourth quarter of a basketball game. The slate is clean, and the momentum is up for grabs. You'll often see "AS" on scorecards, leaderboards, and scoring apps to denote a tied match.
For example, if you win Hole 1 and your opponent wins Hole 2, the match is now All Square. Even though you might have a total of 7 strokes (a 3 on the first, a 4 on the second) and your opponent has 8 strokes (a 4 on the first, a 4 on the second), your stroke total is irrelevant. You've each won one hole, so you are AS.
Scenarios That Lead to an "All Square" Match
A match can be All Square at any point during the round. It can start out that way (obviously, before the first hole is completed), return to it in the middle of the round, or even end that way after 18 holes, leading to a sudden-death playoff.
Here are the common ways a match stands at or returns to All Square:
Halving Holes from the Start: If you and your opponent both make par on Hole 1, you've "halved" the hole. The score remains tied. If you both make bogey on Hole 2, you halve that one as well. The match is still All Square. You can be standing on the 5th tee and if every hole so far has been halved, the match is AS.
A Player Who is Down Wins a Hole: This is the most common way a match returns to All Square. Let's say your opponent wins the first hole, putting them "1 Up." On the second hole, you make a birdie while they make a par. You have won the second hole. Their one-hole lead is erased, and the match is now All Square. This constant back-and-forth is what makes match play so thrilling.
An Example Walk-Through of a Match
Understanding the flow is the best way to grasp the concept. Let's follow a hypothetical match through the first five holes:
On the 1st Tee: The match is AS.
Result of Hole 1: You make a 4, your opponent makes a 5. You win the hole.
Score on the 2nd Tee: You are 1 Up.
Result of Hole 2: You make a 5, your opponent makes a 4. Your opponent wins the hole.
Score on the 3rd Tee: The match is AS again.
Result of Hole 3: You both make a 3. The hole is "halved."
Score on the 4th Tee: The match remains AS.
Result of Hole 4: You make another birdie 4, and your opponent makes a par 5. You win the hole.
Score on the 5th Tee: You are back to being 1 Up.
Result of Hole 5: Your opponent wins the hole.
Score on the 6th Tee: The match returns, once more, to AS.
As you can see, the score isn't a simple accumulation. It's a dynamic status that reflects the current state of the duel. One good shot or one bad mistake can bring a match right back to All Square.

Understanding the definition of AS is one thing, but understanding its strategic and psychological impact is what separates good match players from average ones.
Being All Square feels like a reset button. Whether you were just 2 Down and fought back, or you were 2 Up and just lost two in a row, the moment the match returns to AS, everything starts fresh. The pressure can shift dramatically. The player who was trailing now feels a surge of momentum, while the player who lost their lead might feel flustered.
From a strategic standpoint, your approach from an All Square position depends on the situation:
Early in the Match (Holes 1-6): When you're AS early on, you might play a bit more aggressively to try and seize an early lead. You know there are plenty of holes left to recover from a mistake, so firing at a tucked pin might be a risk worth taking to put some pressure on your opponent.
Middle of the Match (Holes 7-13): Being AS here is a pivotal moment. You’re evaluating your opponent’s game. Are they making mistakes? Are they hitting the ball well? This is often a time for solid, conservative "fairways and greens" golf. Don't make a big mistake that hands them a hole. Let them make the error. Your goal is to apply steady pressure and wait for an opening.
Late in the Match (Holes 14-18): This is when a match that's All Square feels a thousand times more intense. Every shot carries immense weight. You can't afford a careless bogey. Here, your strategy should be tailored to the specific hole and your opponent’s situation. If they hit their tee shot into the trees, your simple play to the center of the fairway becomes a massive advantage. Conversely, if they stick their approach to 10 feet, you might have to take on a more heroic shot to avoid going 1 Down with only a few holes to play.

Once you are comfortable with "All Square," a few other terms will complete your match play vocabulary.
Concession: You can "concede" a stroke, a hole, or the entire match. If your opponent has a 1-foot putt for par and you've already made a bogey, you'd typically say "that's good" or "pick it up." This is a concession of their next stroke. Conceding a putt is good sportsmanship and speeds up play. You can also concede the entire hole if you hit a ball out of bounds and your opponent is on the green in two.
Halved: As we've discussed, this is the term for a tied hole. It’s like a draw or a push. No one goes up or down in the overall match score.
Dormie: A match is "dormie" when one player's lead is equal to the number of holes remaining. For example, if you are "3 Up" with only three holes to play (16, 17, and 18), you are dormie. Your opponent must win every remaining hole just to tie the match. If you halve or win any of the remaining holes, you win the match. It's considered an almost insurmountable lead.
Final Thoughts

Match play is a strategic battle, and making the right decision on a critical tee shot or a tricky approach can be the difference between winning a hole or losing it.
