TIL that Checkers has been a solved game for almost 20 years. Optimal play is unbeatable, and two opponents playing optimally always reach a stalemate.

Favorite anecdote from the team who solved it, who trained with Marion Franklin Tinsley, the single-greatest player ever to walk the earth:

In one game, Chinook, playing with white pieces, made a mistake on the tenth move. Tinsley remarked, "You're going to regret that." Chinook resigned after move 36, fully 26 moves later. The lead programmer Schaeffer looked back into the database and discovered that Tinsley picked the only strategy that could have defeated Chinook from that point and Tinsley was able to see the win 64 moves into the future.

Tinsley once remarked that he had become bored playing humans; there wasn't any challenge left. When he was young, Tinsley began to acquire the reputation of being unbeatable. For 45 years, most of his opponents would play for the draw; going for a win was unthinkable. Tinsley's enjoyment for the game waned, and at one point he retired from the game for 12 years because of a lack of competition. When the checkers program Chinook came on the scene, Tinsley relished the opportunity to play it. Chinook had no respect for Tinsley's abilities, willingly taking risks; anything to increase the chances of winning. Tinsley said that playing Chinook made him feel like a young man again.

Tinsley lost only 7 games in his 45 year draughts career, 2 of which were to Chinook, and one of which was part of a simultaneous exhibition

Why didn’t he move to chess? I imagine his ability to see patterns and predict moves would have served him very well, while the advanced complexity of chess coupled with the basically limitless skill ceiling would have left him never bored.

i'm sure he dabbled some, but it probably just isn't for him, it's probably kinda the same reason michael jordan turned out bad at baseball, tbh

like yeah baseball and basketball aren't the same, but you didn't see him playing football either, and that at least involves the concept of carrying a ball down the field to a goal line?

i'm sure some sporting fundamentals carry over, but it's not the same thing, not the same game, not the same objectives to manage, not the same motions, etc; it's probably never the same as the one unique thing you were naturally crafted to be the world's best at

you gotta understand that at some point when you become the master of your art, it's not really about just "i want to be competitively challenged in general", for him it's some kind of mileu of "is there even anyone else around who understands this thing like I do? can anyone show me something new about this thing?"

It's important to remember he did retire for a long time, until computer play had sorta breathed new life into the game; when he found something, anything at all, that could keep up with his level, that had to be a huge inspiration; especially because it comes with this prospect of being able to contribute to something of a legacy in the conversion to solving the game outright

Fwiw, my understanding is that Jordan wasn't bad at baseball.

The guy hadn't played since high school, and was in his 30s. He was then able to hit over .200 and draw a bunch of walks in AA ball.

I'm aware that it's not the major leagues, but for going up against young guys who haven't taken 15 year breaks from the game, and are trying to advance to the bigs, that's pretty dang good.

I read commentary from an MLB pro (I forget which one, it was awhile ago) that felt that MJ could've legitly made it to the majors as a backup player in a reasonable amount of time, with the way he was improving.

Jordan was phenomenal at baseball given how long it had been since he played competitively. He just randomly decided he wanted to play minor league baseball, and was able to do so without embarrassing himself. He was quite likely among the best 3,000 or so baseball players in America in 1994... all without having played since he was a teenager and having only one season of actual practice/competition.

Yeah im aware of that, I certainly wouldn’t expect him to be the best but I would expect him to be great.

There are game streamers who often reach a peak in a certain game and it’s usually what starts their career off. Later you’ll see them change games as their old game slowly grows stale or they want a change a pace. Even if the games aren’t too similar, they will be very very good. Often times not as good as their last game, sometimes about the same level, and rarely they will be even better and dominate in the next game. It’s because of the skills they developed previously and just how their brains are wired.

I’m just surprised he never tried to do both if he was so bored at winning checkers. Honestly chess would probably be even more enjoyable for him since he would actually be challenged. Maybe it was a fear of losing or the daunting prospect of learning a whole new game. Or maybe he just liked being the best at one thing and that was that.

Or maybe he just didn’t like chess for whatever reason lol.

There’s no doubt he could have been great, maybe not Fischer or Carlson level but certainly a good player. Guess we’ll never know.

believe it or not, some people with incomparable natural talent just like to participate in an expression of their talent

he was an engineer and mathematician, so probably the game's state space 'made sense' to him in some way that he can 'just see' the branches in the game tree; he's played for so long and grown so familiar with the game that its domain model must just feel like another room in his house or something

it's probably not so much 'playing' when he plays against other people as much as like navigating a map to 'winning game state' in his head - he knows that #10 move is bad in the same way you'd know if your Uber driver takes a weird turn to get you home

Checkers =/= draughts (10x10)

Tinsley wasnt a draughts champion, but a checkers champion. Draughts is a bigger board with different rules and has a much more serious (competitve)international field.

So Tinsley might have been the best checkers player in the world, he never competed at the highest level of 10x10, which is much more popular in Europe/Africa.

Checkers (or chequers) is a synonym for draughts. The 10×10 variant is very much a niche thing; it may be popular with "elite" players, but if you buy a draughts set in a shop, it's going to come with an 8×8 board.

u/LanceFree 12h ago

During the human potential movement in the 1990s, we played a game with seemingly no way to win. The lesson or learning was that they never said the two teams were opposed, and if they worked together, both sides would win. When we kept losing and losing, things got heated, some people wanted to try their idea or nothing at all. I was told some people on the other team came close to throwing punches. My own behavior was also faulty. Basically after two turns, I checked out, and started to hate the type-A people. Good exercise.

The best way to win at Monopoly is to not play it.

The second best way to win at Monopoly is to buy up as many houses as possible, then refuse to upgrade to hotels, and cockblock all the other players from being able to buy houses.

I grew to truly loathe Monopoly and I reached a point where I have no desire to ever play it again. There was only one time where I had a fun time. That was the time when I decided that I would secretly pursue a completely different goal than everyone else... to hoard all of the one-dollar bills. And nobody noticed until they were finally all gone, and then everyone finally saw my huge pile of ones (sitting right there in the open the whole time). I won! That was the most fun I ever had playing that accursed game.

The "building shortage" also prevents buying hotels, as the rules state that you must have four houses first. It also prevents selling hotels down to houses, because the house tokens must be available to be placed on the property. This means that hotels have to be sold completely. I win 100% of the time using this strategy (oh, and no Free Parking payouts--it's not part of the rules, and is the reason games can last hours and hours).

ed: changed "housing shortage" to "building shortage".

24

u/Daztur 12h ago

Also you have to use the auction rules, which also speeds up the game.

The only house rule I like to use is to allow people to buy properties ADJACENT to where they land (but still a max of 1/turn) as it speeds up the game and makes it a bit more strategic as you can't just mindlessly buy any property you can or you'll run out of money.

Game is decent enough that way.

Most of the complaints people have about Monopoly stem from all the "house rules" people insist you play with.

The one valid complaint is that it isn't much fun. It wasn't designed to be a fun game, it was designed to teach you to hate capitalism.

December 31, 1999, being an incredibly cool teenaged individual, I was of course engaged in a 7 man game of Diplomacy on new years eve. I executed a timely backstab that resulted in my one good friend getting knocked out of the game and he still refuses to speak to me, to this day. It's been almost 27 years.

The other highlight of the evening, my other friend who was hosting's parents were throwing a NYE party upstairs and we were playing in the basement.

At the stroke of midnight, we flipped the main breaker on the electrical panel.

(For context for the younger folks, there was a tremendous amount of talk in the mainstream news leading up to the millennium that computers would stop working, power plants would go offline, airplanes would fall out of the sky, etc etc as a result)

I remember just....SUDDEN SILENCE from upstairs, followed by panicked screaming.

I played a lot of Diplo in high school (thanks to my AP European History teacher who made it part of his class!) and in college as well.

New folks fucking LOVE to betray in the first couple of turns and then LOVE to crash out when their betrayal doesn't work all that well.

The game taught me the concept of social capital, and that it turns out if every time you play you backstab, eventually no one will trust you even on a fresh board. Had one dude who stopped playing with us entirely because he was so conniving that no one would ever work with him. His final game with us, as a known rake, was as Germany. Turn one was Russia, Austria-Hungary, Britain and France all deciding the partition.

Only rule is absolutely no showing/sharing contents of emails/texts - you can say what someone sent you but you can't share the actual privileged conversation or images of it or anything. It works great gives even busy friends time to do some thinking/'get a good turn in'.

The turn executes at 7PM on Sunday we resolve it and you're back to lying to your friends on Monday morning for a week!

Diplomacy is my all time favorite game because there is no luck. It is 100% on your ability to read and convince people.

That being said it’s hard to find exactly seven people and at least one person usually gets knocked out early so it’s a bit of a scheduling challenge.

It never occurred to me that some people try to play this game in long sessions. Every time I've played, the game takes place over weeks. Play it 1-2 turns per day at a pre-scheduled time. The best part of playing it that way is how much time you have to break off and scheme with other players without being overheard.

It leads to great moments where you realize that the friend who spent an hour over text convincing you to help him out with a joint attack on Austria-Hungary was actually letting another player write all their messages, in exchange for support elsewhere on the board.

Yeah, I just wanted to clarify because it sometimes feels like people think that once a game is solved, there’s little point in playing, because you can just play perfectly and you will always draw.

However, for games as complicated as checkers, playing perfectly without a look-up table is not some simply implemented strategy and is essentially impossible for anyone who is not a “checkers grandmaster”.

u/MeeTy 11h ago

For "checkers grandmasters", is there still meaningful play at the highest level of play or is it an obvious draw?

There used to be world championships.

The story about Marion Tinsley and Chinook is worth reading (and can be found on Marion’s Wikipedia page).

Nowadays, I don’t think there are official world champions or “grandmasters.”

Like Chess, Checkers was already a game that often ends in draws between very strong players, so a match involves several games so that the tie can be broken.

Edit: I stand corrected on the champions and grandmasters. Honestly, should have assume that competition was still going. I had some vague recollection of a competition being discontinued.

A big part of why it is so easy to solve is due to the starting position leading to very few lines relative to actual possible board states. But the reality is we already knew optimal checkers openings anyway. So standard checkers opening strategy is the answer. There are many ways to play for a draw. Every first move is still a draw. And in the first 8 moves or so every drawing line is already theory without a computer.

u/Kor_Phaeron_ 7h ago edited 5h ago

Btw, with perfect play from both sides, chess is widely believed by theorists to be a draw. Since we can't solve chess due to its complexity there are strong data points for this conclusion.

  • The data reveals that as material is reduced, the defensive resources of the trailing or equal side scale incredibly efficiently. Even massive material imbalances—such as a lone King defending against a King and two Knights—are mathematically proven forced draws. This strongly suggests that White's tiny fraction-of-a-pawn first-move advantage is far too small to force a breakthrough against perfect play.
  • In game theory, an advantage of the first move (+0.20 and +0.40) is regarded as a "temporary initiative" rather than a winning advantage. To actually force a checkmate, an evaluation typically needs to cross a threshold closer to +1.5 or +2.0, which Black can easily prevent from the start by simply mirroring or neutralizing White's space.
  • Human data at the World Championship level shows that when a player chooses an opening designed strictly to equalize rather than create dynamic imbalances, White cannot force a win.
  • In elite computer tournaments like the TCEC (Top Chess Engine Championship) if engines are allowed to play from the standard starting position rather than forced, unbalanced openings, virtually 100% of the games end in a draw.

It's actually an interesting phenomenon that so many board games just happen to result in draws with perfect play. Especially given most of them were invented long before we could ever know or prove that. Chess, Checkers, Othello, probably Go.

u/Aarakocra 11h ago

Go is not balanced for a draw, and the rules have evolved over time to specifically balance it better. It is point based so a draw could have only happened if the number was specifically even. But it favors the first player enough that there are points for going second called komi that didn't get implemented until the 20th century. And even then, the amount has changed from as low as 2.5 to 7.5 (the 0.5 is to let second player win in a tie).

u/yodatsracist 10h ago edited 6h ago

Tafl games, also known as Viking Chess. Very fun to mess around with but it’s (obviously) unbalanced and one side has an advantage. These were popular in Scandinavia and are mentioned in the Norse sagas. They were played by the Sami (indigenous non-Indo-European group in Norway, Sweden, and Finland) until the 18th century, though they seem to originate with the Norse.

Fox games (Fox and Geese, Fox and Hounds, etc) are potentially related. They were once popular among the Anglo-Saxons, but variants are played as far away as Sri Link.

Both involve attackers and defenders, with the attackers having more pieces and the defenders being hard to capture.

Both are great with kids! They make you think in different ways. I recommend them, even though in most variants the defenders have an advantage. Edit: Someone below pointed out that Wikipedia talks about how the first published variant was misunderstood and in the original rules it actually favored the attackers. This is true, but most variants overall favor defenders. See here for way too much detail.

Edit 2: if you're looking on US Amazon, the version I had of Tafl is available as "Hnefatafl - The Viking Game - Authentic National Museums Scotland Version". I bought it in about 1998 and it was published by English Heritage, the organization that runs many of England's most famous sites, including Stone Henge. I guess this is the Scottish version. It's also on UK Amazon as "Hnefatafl - The Viking Game", also the blue box Museum of Scotland version. It's got a cool cloth mat instead of a board, and the pieces are such cool looking Viking soldiers I played with them even when I wasn't playing. They're modeled after the Lewis Chessmen (12th-century Viking chess pieces carved out of walrus ivory), which is slightly anachronistic but who cares. I introduced it to my nephews and son and they were obsessed with it. It's expensive like 45 dollars/30 pounds, round about, but I got my money's worth over 30 years. It's literally lasted a generation. There are also a couple of Chinese knock-offs on Amazon but they seem to be roughly the same price. If you're going to buy a Tafl game, it seems like maybe worth getting some version with cool looking pieces. If you go down to the end of the Wikipedia for Tafl games, you can also find places to play online. Not everyone prefers the English Heritage/National Museum of Scotland re-creation.

I have no special recommendation for Fox games, but you could probably just draw the board on paper and find the appropriate number of pieces.

20

u/HotterRod 8h ago

From the Wikipedia article you link to:

There have long been controversies concerning imbalance of the game, as rules for certain modern tafl games strongly favor the defenders. This imbalance results from a mistranslation of Linnaeus' rules for tablut, a Sámi tafl game from the 1700s, which were subsequently used as the basis for reconstructions of rules for medieval tafl. Newer translations of Linnaeus' tablut rules reveal a balanced game. After this change, tablut can be said to be slightly in favor of the attackers rather than the defenders: according to statistics, the attackers overall win marginally more often (on average 9% more).

u/sampat6256 12h ago

If you let two engines play each other without any restrictions, they almost always draw, so youre not wrong, but we don't yet know if that's a technological limitation or an inevitable feature of the game.

26

u/liberty 10h ago

That said, when top chess engines do not draw, white almost always wins, and it's not even close. So the game is somehow both highly balanced and highly imbalanced at the same time.

u/Few_Classroom6113 8h ago

Game so balanced starter advantage is the only edge to gain.

u/Willrkjr 8h ago

Well, that’s sort of the thing about balance. If the other guy has a gun, and I have a knife starting at 100 yards, with “perfect play” it might be a “draw” in that I can’t get any closer and he can’t land the shot. But to play “perfectly” is much easier for the guy with the gun than it is me trying to close the distance on him with my knife, and in the event players aren’t playing perfectly one side gets to their win condition easier

Matches between chess bots use openings which are chosen for them, after which the bots take over. Otherwise they would probably just keep using the same drawish openings.

u/Soft-Run-3577 11h ago

I am not sure this is true for modern bots from the standard starting position. In slightly imbalanced positions, its easier to see differences but I would guess that they would never play into these unbalanced positions under normal play.

The game of go typically could never end in a draw if playing by a standard ruleset where a fractional 0.5 Komi point is given to white for going second. There are different levels of Komi given but they always have the 0.5 point afaik. If you don’t play with a non standard then I imagine draws could be pretty frequent between two professionals. They win and lose by that half point frequently enough if they get to end game. I think as a beginner, I’ve had a game down to 1.5 points before in scoring.

Go is a fascinating game and after I learned it a bit, it took over my love of chess.

It's the classic case of game theory with a 2-player mirrored game with perfect knowledge by all players.

As long as the first player plays perfectly, they cannot lose. Simultaneously, in those conditions, the first player will also always win unless player 2 also plays perfectly.

u/bluesam3 6h ago

Those conditions are not sufficient: trivially, you can have a game where the only available move is "resign", in which going first makes you lose. You can extend that backwards with an arbitrarily long zugzwang sequence.

> is it's actually impossible to just have optimal play.

This isn't right.
Consider all possible sequences of moves and all end game states.

Now eliminate all final moves that result in the player to move losing.
Repeat with the second to final move and so on...

What remains is the optimal strategy.
If there is a starting move that results in a win/lose, then the game is unfair. Otherwise Chess can always result in a draw.
The optimal strategy is constructable and it exists, therefore it's not impossible to play perfectly.

What we don't know is how to construct this strategy in a reasonable amount of time. There are way too many moves in a game of chess to compute the perfect strategy.
We don't have any evidence that it's impossible to build out this strategy in a reasonable amount of time though or even encode it in a system that's easy enough for a human to memorize and follow.

u/ManaPlox 9h ago

I didn't play competitively or a lot or anything. But I always won. The strategy took things I knew and understood from chess. I have lost 2000+ games of chess so I am not great.
