What Does A/S Mean in Golf?

You’ve been grinding all day, trading blows with your opponent in a close match. You walk up to the next tee, glance at the large scoreboard or handheld scorecard, and see two letters next to your names: A/S. Seeing this can stir up a lot of feelings - pressure, relief, determination. So, what exactly does it mean? This guide will break down what A/S stands for, how it differs from other scoring methods, and - most importantly - provide you with a coach's perspective on the strategy you need to win when your match is tied.

What A/S Actually Means in Golf

In golf, A/S stands for "All Square." This term is used exclusively in match play and simply means that the match is tied. Neither you nor your opponent has a lead. You have both won the same number of holes, bringing the score back to neutral.

Think of it as hitting the reset button. The match starts as A/S on the first tee. If your opponent wins the first hole, they are "1 Up." If you then win the second hole, the match returns to being "All Square." This back-and-forth continues until one player wins the match outright or you finish the 18th hole All Square, resulting in a tie (or a "halved" match unless a playoff is required).

The term A/S is a core part of the match play language and signals that, at that moment, it’s anyone’s game.

Match Play vs. Stroke Play: The Two Worlds of Golf Scoring

To fully grasp why A/S is so important, you need to understand the fundamental difference between the two main ways golf is scored. For newer golfers, this can be a point of confusion, but it's simpler than you think.

Match Play: The Head-to-Head Duel

Match play is a hole-by-hole competition. You are playing directly against an opponent, and each hole is a self-contained battle. The total numbers of strokes you take over the entire round don't matter as much as who wins each individual hole.

• Winning a hole: You take fewer strokes on the hole than your opponent. You go "1 Up."
• Losing a hole: Your opponent takes fewer strokes than you. You go "1 Down."
• Halving a hole: You both take the same number of strokes on the hole. The score of the match remains unchanged.

In this format, a terrible score on one hole isn't catastrophic. If you find trouble and score a triple bogey while your opponent makes a par, you only lose one hole. You don't carry that high score with you. This is the format where you will constantly see the term A/S used to denote a tied score.

Stroke Play: The Individual Grind

Stroke play is the format you’re probably most familiar with from watching professional tournaments like The Masters or the U.S. Open. The goal is simple: count every single stroke you take from the first tee to the final putt on the 18th green. The player with the lowest total score at the end of the round wins.

In stroke play, every shot counts equally, and one bad hole can derail your entire round. There is no concept of "Up," "Down," or "All Square." Players are just ranked by their total score in relation to par (e.g., -5, E, +2). The equivalent of being All Square in stroke play is simply being "tied" with another player at the same score.

Coach’s Corner: How to Strategize When Your Match is All Square

Knowing what All Square means is one thing, knowing how to play when you're All Square is what separates good match play competitors from the rest. Your strategy should evolve based on what point you are at in the match. Let's break it down as if I were caddying for you.

Strategy for A/S Early in the Match (Holes 1-6)

When you're All Square in the opening stretch of a match, the main objective is to settle in and gather information. This is not the time for heroics.

• Play for Conservative Targets: Focus on finding the fat part of the fairway and the center of the green. Solid, stress-free pars are your best friend early on. This puts pressure on your opponent to beat you rather than you beating yourself.
• Observe Your Opponent: Pay close attention to their game. What is their miss? Are they struggling with a hook or a slice? Are they uncomfortable with short-sided chips? Do they get tentative over 4-foot putts? Every piece of information you gather now can be used to your advantage later.
• Stick to Your Game: Don't try to be a player you're not. If your opponent blasts a 320-yard drive, resist the urge to swing out of your shoes to keep up. Play your own game, hit your comfortable shot, and trust your strategy. The goal is to avoid making a big mistake that gives away a free hole.

Strategy for A/S in the Middle of the Match (Holes 7-12)

The middle part of the round is where you start making your move. You've settled in, you understand your opponent's tendencies, and now it's time to start applying intentional pressure.

• Identify Opportunity Holes: Look at the scorecard. Is there a short Par 4 that suits your eye? A Par 5 where your normal drive gives you a chance to go for the green in two? These are the holes to become more aggressive. Don't force it, but when a clear opportunity presents itself, take it.
• First on the Green Mentality: Being the first player to have your ball safely on the putting surface applies significant psychological pressure. When your opponent is standing over an approach shot or a chip knowing you are already on the green waiting, they are more likely to make a mistake.
• Calculated Aggression: This doesn't mean aiming at every flag. It means being aggressive with your targets. Instead of just aiming for the middle of the green, perhaps you aim for the side of the green that gives you an uphill putt. It's about being strategically aggressive, not reckless.

Strategy for A/S Late in the Match (Holes 13-18)

This is where matches are won and lost. Being All Square with only a few holes to play is one of the most exciting (and nerve-wracking) situations in golf. Nerves are high, and smart decision-making becomes everything.

• Play the Opponent, Not Just the Course: Your opponent’s shot should dictate your strategy. If they hit their tee shot into the trees, your game plan changes instantly. Don't feel the need to hit a perfect driver. The smart play is to hit an iron or hybrid into the middle of the fairway. A simple par will almost certainly win you the hole. Conversely, if they stick their approach to 10 feet, playing for the "safe" middle of the green won't cut it. You may have to take on a tougher flag.
• Embrace the Halve: Never underestimate the power of a halved hole when you are A/S late in the match. If your opponent has a short putt to tie the hole, all the pressure is on them. You haven't lost anything. When they have to make a clutch putt just to avoid going "1 Down," the pressure can be immense.
• Routine and Commitment: When nerves kick in, the best thing you can do is fall back on your pre-shot routine. Take deep breaths, pick your target, make a committed swing, and accept the result. Overthinking or hesitation is the enemy in these moments. Trust the yardage, trust the club, and trust your swing.

Understanding Dormie: The Final Checkmate

While not A/S, another key match play term is "dormie." A player or team is dormie when they are leading the match by the same number of holes that remain to be played. For example, if you are "3 Up" with three holes to go, you are dormie. This means your opponent must win every remaining hole just to tie the match. It's the ultimate position of power, and often, getting to dormie begins with a smart decision when the match was still A/S.

Final Thoughts

A/S, or All Square, is the simple language of match play that signifies a tied match. It represents a a clean slate, a chance for a comeback, and the neutral ground from which every head-to-head battle begins and often returns.
