Squares2Circles: Course strategy refined by a Ph.D.
What do you get when you combine Division I-level golf talent, a Ph.D. in Mathematics, a passion for understanding how people process analytical information, and a knowledge of the psychology behind it? In short, you get Kevin Moore, but the long version of the story is much more interesting.
Kevin Moore attended the University of Akron on a golf scholarship from 2001-2005. Upon completing his tenure with the team, he found himself burned out on the game and promptly hung up his sticks. For a decade.
After completing his BS and MS degrees at the University of Akron, Kevin then went to Arizona State to pursue his Ph.D. Ultimately what drew him to the desert was the opportunity to research the psychology behind how people process analytical information. In his own words:
“My research in mathematics education is actually in the realm of student cognition (how students think and learn). From that, I’ve gained a deep understanding of developmental psychology in the mathematical world and also a general understanding of psychology as a whole; how our brains work, how we make decisions, and how we respond to results.”
In 2015, Kevin started to miss the game he loved. Now a professor of mathematics education at the University of Georgia, he dusted off his clubs and set a goal to play in USGA events. That’s when it all started to come together.
“I wanted to play some interesting courses for my satellite qualifiers and I wasn’t able to play practice rounds to be able to check them out in advance. So I modified a math program to let me do all the strategic planning ahead of time. I worked my way around the golf course, plotting out exactly how I wanted to hit shot, and minimizing my expected score for each hole. I bundled that up into a report that I could study to prepare for the rounds.
“I’m not long enough to overpower a golf course, so I needed to find a way to make sure I was putting myself in the best positions possible to minimize my score. There might be a pin position on a certain green where purposely hitting an 8-iron to 25 feet is the best strategy for me. I’ll let the rest of the field take on that pin and make a mistake even if they’re only hitting wedge. I know that playing intelligently aggressive to the right spot is going to allow me to pick up fractions of strokes here and there.”
Here’s what the leaders have to look forward to as they close “The Bear Trap”. The 17th plays to a mere 156 yards today, but any play at the pin depth or line necessarily brings the penalty area into play. Commit to a line, hit the shot, and accept the result. pic.twitter.com/g0a2qqCv3E

His plan worked, too. Kevin made it to the USGA Mid-Amateur at Charlotte Country Club in September of 2018 using this preparation method for his events just three years after taking a decade off of golf. In case you missed the implied sentiment, that’s extremely impressive. When Kevin showed his reports to some friends that played on the Web.com Tour and the Mackenzie Tour, they were so impressed they asked him to think about generating them for other people. The first group he approached was the coaching staff at the University of Georgia, who promptly enlisted his services to assist their team with course strategy in the spring of 2019. That’s when Squares2Circles really started to get some traction.
At that point, UGA hadn’t had a team win in over two seasons. They also hadn’t had an individual winner in over one season and had missed out on Nationals the previous two seasons. In the spring of 2019, they had three team wins (including winning Regionals to advance to Nationals) and two individual wins (including Davis Thompson’s win at Regionals). Obviously, the credit ultimately belongs to the players on the team, but suffice it to say it appears as though Kevin’s involvement with the team was decidedly useful.
“One of the things we really focused in on was par 3 scoring. They finished 3rd, 2nd, 4th, and 3rd in the field as a team in their spring tournaments. Then at the SEC’s they struggled a bit and finished 6th in the field. At Regionals, they turned it around and finished 1st in the field with a score of +6 across 60 scores (186 total on 60 par 3’s, an average of 3.10).”

Kevin is available outside of his work with UGA and has been employed by other D-I teams (including his alma mater of Akron), Mackenzie Tour players, Web.com Tour players, and competitive juniors as well. Using his modified math program, he can generate generic course guides based on assumed shot dispersions, but having more specific Trackman data for the individual allows him to take things to a new level. This allows him to show the player exactly what their options are with their exact carry numbers and shot dispersions.
“Everything I do is ultimately based off of strokes gained data. I don’t reinvent the wheel there and I don’t use any real new statistics (at least not yet), but I see my role as interpreting that data. Let’s say a certain player is an average of -2.1 on strokes gained approach over the last 10 rounds. That says something about his game, but it doesn’t say if it’s strategy or execution. And it doesn’t help you come up with a practice plan either. I love to help players go deeper than just the raw data to help them understand why they’re seeing what they’re seeing. That’s where the good stuff is. Not just the data, but the story the data tells and the psychology behind it. How do we get ourselves in the right mindset to play golf and think through a round and commit to what we’re doing?”
“Even if you’re able to play practice rounds, this level of preparation turns those practice rounds into more of an experiment than a game plan session. You go into your practice round already knowing the golf course and already having a plan of attack. This allows you to use that practice round to test that game plan before the competition starts. You may decide to tweak a few things during your practice round based on course conditions or an elevation change here and there, but for the most part it’s like you’ve gained a free practice round. It allows you to be more comfortable and just let it fly a lot earlier.”
Kevin is in the process of building his website, but follow @squares2circles on Twitter for more information and insight.

AVL: We’re talking about practice! My best tips for taking your game to the course
With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter. More sunlight also means more time to get out on the course and work on your game.
Whether it’s the practice green or the driving range, there’s always something to improve—whether you’re enjoying the fresh air or preparing for a weekend game or tournament. You can work on drills or freestyle around the green, and friendly competition is a great way to sharpen your skills.
While there are endless ways to get better at golf, I’m going to focus on practicing around the green. Let’s take a look at a few things to keep in mind as we head into the summer months.
Drills
From the driving range to the practice green, it’s important to incorporate drills into your routine. Years ago, I spent a weekend working on my short game with James Sieckmann. He recommended doing drill work for 5–10 minutes, then returning to your main practice.
This way, you create a balance between structured drills and real-world scenarios, so you’re not confined to “perfect” situations. For example, hitting the same three-foot putt over and over is good for repetition, but after a while, it becomes less interactive for your brain.
My approach is to use a putting trainer with a narrow gate for the ball to pass through, or simply place tees just outside the width of the ball. I’ll hit a series of four putts through the gate for three sets. Then, from a similar distance, I’ll hit four putts without the training aid and repeat that sequence three times.
Next, I’ll hit a number of 15–25 foot putts in a random fashion, then circle back to repeat the short putt drills with and without the training aid.
This breaks up the rhythm of hitting short putts with the training aid. When you hit the same short putts over and over, it’s easy to get into a groove—which is great for the drill, but not reflective of actual course play. While finding a rhythm is fundamental for drills, I like to introduce variation with longer putts to keep things realistic.
Game Mode
Once you’ve established a foundation with drills, it’s time to simulate on-course scenarios. This is where a few practice games come in handy.
One that I’ve been enjoying lately involves putting 10- to 15-footers with two balls. If I make the putt, great! If I miss, I pull the missed ball back a putter length. Suddenly, that little tap-in becomes a nerve-wracking three-footer—at least at first. As you get better at this game, those three- and five-footers become much more comfortable and routine.
It may sound cliché, but each shot is just what it is—it’s how we react that makes the difference. I like this game because it blends the pressure of on-course putting with the consequence of leaving yourself a much longer putt than usual.
Another game I like is one I recently learned from Brad Faxon. Place three tees in a line at four different locations around the hole: one at 3 feet, one at 6 feet, and one at 8 feet. The 3- and 6-foot putts count as par, and the 8-footer is for birdie.
This game keeps you focused on scoring and helps you get into a competitive mindset. You can even think about this putting game while you’re on the course. I just started playing it, and last week I couldn’t get better than two under par.
Competition
Competition during practice is when drills and games come to life, and you start to see results. For me, nothing beats a putting contest with a friend or two. In the right setting, these contests can become talking points for the whole season.
Match play, a game of 21, or simply seeing who can make the most one-putts (with a small prize on the line) are all great ways to simulate real on-course pressure. Recently, I played in a putting contest where one competitor made back-to-back 30- and 50-foot putts. As they say, expect your opponent to make every putt—and he nearly did. That’s impressive, and it’s something you see on the course, too: you have to stay committed to your game plan, no matter what.
When it comes to practice, it’s important to blend feedback from recent rounds with the fundamentals you want to reinforce. Drills, games, and competition—from the driving range to the putting green—form the backbone of skills you’ll rely on during actual rounds.
Finding the right balance is something we’re all working on, one practice session at a time. With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter.

Seoul Sensibilities: Is Korean golf fashion starting to shape the world?
For Korean golfers, we always look forward to the last of the kkot-saem-chu-I for the true start of a new golf season. The term refers to a cold snap, but literally translates as “winter being jealous of the flowers beginning to bloom, thus lashing out one final time before surrendering to spring”.
A rather poetic mouthful packed into a short expression.
Koreans can be like that. Understated, yet oddly expressive at the same time. And nowhere is this more true on the golf course and in our golf bags. In fact, I suspect many Korean golfers look forward to new apparel and accessory drops more than they do actual equipment launches each year.

At this point, Korean golf fashion may exist on its own timeline. (courtesy of @seonbi_golfer)
There is ample evidence to support that suspicion. Korea is the world’s third-largest golf market behind the United States and Japan, yet its appetite for golf apparel exceeds that of both countries combined. Recent estimates suggest that Korea accounts for nearly 40 percent of the global golf apparel market, placing it among the world’s most influential golf fashion markets and punching well above its size.
Simply, we care deeply about how new golf clubs look and feel, but enjoy looking good while swinging them even more.
Golfers in the West may laugh and say that golf is played on a course, not a fashion runway. Perhaps. But what’s the harm in trying to look and feel good, if the added self-confidence can help actual performance? It certainly seems to have worked for Jason Day, who may have unlocked a new stats category: dormant strokes gained. Coincidence?

During the COVID-era, estimates placed the market near $9 billion, an astonishing figure for a single country.
As a proud member of Gen X, I’ve witnessed the highs and lows of golf fashion firsthand. The pleated trousers and wing-tipped shoes of Jack Nicklaus, the stylish plus-fours and knickers of Payne Stewart, the baggy black trousers and fitted mock-necks of Tiger Woods, and the thigh-hugging athletic tailoring of Rory McIlroy. Golf fashion, like the golf swing itself, has rarely stood still.
But nowhere have those trends shifted, evolved, and been scrutinized quite as relentlessly as in Korea. Here, golf fashion moves faster than fairway gossip, and consumers dissect brands with a level of discernment that can be both impressive and mildly terrifying. New brands are studied, judged, embraced, or dismissed with startling efficiency.
The result is a consumer base with one of the sharpest eyes for quality and authenticity anywhere in the world. It is difficult to quantify, but easy to recognize. Clean lines without trying too hard. Luxury mixed with utility. Trend awareness balanced by restraint and purpose.
It’s golf fashion shaped by one of the world’s most style-literate cities, something I like to call Seoul Sensibilities, referring to the taste level forged by a uniquely competitive environment.
And increasingly, global brands have noticed.

Many golf brands in Korea have their own flagship shops dedicated to apparel only
Titleist understood this years ago, when its apparel business in Korea took on a life of its own under new ownership and local direction. What had once been a straightforward extension of an iconic equipment giant became something sharper and more premium. By going all in on the serious Tour-player look (I couldn’t even fit into their XL sizes), Titleist struck the right chord with Korean consumers and helped its fledgling apparel business break into the mainstream. Titleist became a household name even for non-golfers who wore its caps, shirts, and windbreakers in daily life. In many ways, it proved that even heritage golf brands could carry real fashion credibility when viewed through a Korean lens.
Several years later, PXG took a page out of Titleist’s playbook and followed suit. Korean consumers helped transform the brand from one known largely for irons and loud commercials into something broader and more stylish. PXG apparel’s growth in Korea was explosive, where it found an early audience and turned the category into something more than mere logo merchandise. It is still hard to walk anywhere in Seoul without seeing its palindrome logo.
Malbon’s meteoric rise in the United States was genuine, but its ascent into a global golf lifestyle brand owes much to Korea, where it was elevated by a market already fluent in modern golf style. Korea did not simply embrace Malbon. It pressure-tested the concept, refined its appeal, and helped push it into the global spotlight.
As such, new brands may arrive from abroad, but more often than not, their sharpest evolution happens here. If a brand can earn credibility in Seoul, it’s deemed to have passed one of the toughest style audits in the game.
That is why the next meaningful chapter may not come from outside, but from a Korean brand moving in the opposite direction, carrying those Seoul Sensibilities outward as K-pop once did.

Play young Stay dope.
From Seoul, With Intent
Khalhon is a label that feels less like a trend-chasing newcomer and more like the product of a market that has already seen everything. Golfers here have long been surrounded by luxury logos, technical fabrics, and tour uniforms disguised as lifestyle wear and vice-versa. In other words, novelty alone rarely lasts here, and the Koreans seems to understand that instinctively.
Its style language leans into clean silhouettes, relaxed but tailored proportions, muted palettes, and premium materials that speak quietly but confidently. There is a modern city aesthetic running through it all, with strong layering pieces, thoughtful textures, and subtle branding that suggests sophistication rather than demanding attention.

“Built for the course. Designed beyond it.”
Most importantly, the garments seem designed to blur the line between golfwear and everyday style. Shirts, trousers, knitwear, and outer layers move comfortably between a game of screen golf, a lunch reservation, an airport gate, or an afternoon coffee in Gangnam with friends.
It raises the question of whether this is golfwear that happens to look good off the course, or everyday clothing that performs beautifully on the fairways.
Personally, I have long appreciated Nike Golf for its clean, athletic modernization of golf attire. It also has the useful side effect of making me look like a more serious golfer than I probably am. But off the course, there are times when being instantly identified as the golf guy in a crowd of non-golfers can feel a touch self-conscious.

“Built for the course. Designed beyond it.”
That is part of what drew me to Khalhon, which seemed to blend golf and everyday wear naturally. While some of the outfits may be slightly beyond my personal confidence level, the brand also offers tasteful options for older guys like me who still want to express a little personality without regretting the decision later.
These are not simply flashy outfits worn on the course and then banished to the closet until the next tee time. They work surprisingly well off the course too, and I suspect many of the pieces will still look right a couple of years from now, which would certainly be kinder to my wallet than most golf fashion trends tend to be.
And perhaps that broader lifestyle positioning also helps explain why someone like Sean Wotherspoon would find Khalhon creatively interesting in the first place.

“Built for the course. Designed beyond it.”
“Korea is not only one of the most fashion-forward golf markets in the world, but one of the most fashion-forward markets globally. Korea is ahead, and I love to watch and try to catch up.” – Sean Wotherspoon, Creative Director at Khalhon
Seoul and Beyond
If Khalhon’s rise says something about where Korean golf fashion is today, its relationship with Sean Wotherspoon says even more about where it is heading.
For readers less familiar with Sean Wotherspoon, his arrival at Khalhon is not some routine celebrity endorsement or influencer collaboration. In design and streetwear circles, Wotherspoon is regarded as one of the more influential creative voices of his generation, particularly when it comes to blending nostalgia, storytelling, and contemporary culture into products that people can connect with.
He first gained widespread attention through his now-famous Nike sneaker collaborations, where his vintage-inspired designs and instinct for color helped turn him into one of the defining artists of the late-2010s sneaker era. His work gradually expanded beyond footwear into apparel, automotive collaborations, collectibles, and broader lifestyle design.
Modern golf style now extends well beyond the fairways, where performance and functionality are largely expected by default. And while plenty of brands already make technically competent golfwear, Khalhon seems more focused on designing clothes people would genuinely want to wear even after the round ends.
And when guys at Wotherspoon’s level show genuine interest in working with a Korean golf brand as its new Creative Director, fashion circles tend to sit up and pay attention. There’s already a huge buzz among the fashion-conscious here about upcoming collabs with iconic sports stars and brands.

“My creative direction for Khalhon is disruptive, colorful, nostalgic, and modern. My goal is to blend these avenues seamlessly within each collection.” – Sean Wotherspoon
In chatting with Sean, what stood out most to me was how genuinely energized he sounded about the project itself. Despite having already worked across and countless other creative spaces, he described golf as a completely fresh category for him, saying that Khalhon “will be an amazing vehicle for my design work.”
At the same time, his enthusiasm seemed tied just as much to Korea itself. He spoke openly about admiring Korea’s fashion culture while repeatedly insisting he is still a terrible golfer.
There was something oddly refreshing about that humility. Rather than sounding like a celebrity parachuting into golf simply because the category suddenly became fashionable, Sean sounded genuinely curious about what Korea might do with the category next.
And perhaps that is what makes Khalhon feel interesting right now. The brand feels less like a trend-chaser and more like the natural result of a market now confident enough to export its own point of view.
For years, global brands came to Korea to sharpen their image against one of the most discerning audiences anywhere. Now, a Korean label appears ready to send those Seoul Sensibilities outward instead.
Which brings us back to kkot-saem-chu-i.
That final cold snap before spring always arrives with a reminder that seasons are changing, whether we notice it immediately or not. Golf fashion feels a little like that right now as well, as the old boundaries between sport, streetwear, luxury, and everyday style continue to soften.
And somewhere in Seoul, a Korean golf label already seems prepared for whatever season comes next. I just hope they have everything in my size.
