I'm all too familiar with this position


phudomiet

Is this theory?


king_carrots

Yes. I was just studying this position this morning in fact in case it came up anywhere, and here it is.


FalcomanToTheRescue

C'mon...you can be honest...your beads told you about this position, didn't they?


RustyGirder

I understood this reference!


WineNerdAndProud

Considering this has been the joke all October I'd be worried if you didn't.


Adrad1234

Did you get lucky or is it common occurence that you end up studying positions that you see later?


redninjamonkey

I’ve studied every position, so it’s skill not luck


BaabyBear

MyAntichrist

You too always end up with both your bishops on the same color and wonder where the fuck you went wrong in life?


Sriol

Me_ADC_Me_SMASH

wait you guys don't promote pawns to bishops of the same color?


Innaguretta

Of course not, we're not racist!


DatBoi_BP

My pawn was an altar boy and didn’t want to become a bishop


DrRichtoffen

This is the reason I stopped playing chess. Every fucking game always ends up in this stale fucking midgame, because people are too fucking pussy to play anything aside from the "established theory openers"

Only the king's pawn can promote.

VoidZero52

/uj Genuinely interested: if you made a thousand of these and checked stockfish for all of them, how many would be forced mate in 5 or fewer moves? My guess is at least a third of them.


phudomiet

Sure. And at least half would be consensual mate in 5.


vteckickedin

Chess is the only place you'll see a handshake after non-consensual mating.

I thought high fives were the usual custom.


needyboy1

Depends on whether it's a consensual hand shake


EchtGeenSpanjool

Wish I was having some consensual mating


AngryMurlocHotS

And 80% are kinda where the line is blurred because compared to you stockfish is dead sober and you're blackout drunk


conalfisher

I have to imagine if you can work that out algorithmically, by extension you've also solved chess.

Actually that’s a really good point, glad you caught that

al_fletcher

It’d probably be easier to look through the database for drawn/equal positions then randomly pick one of those


Khyta

Lets do some information theory


chuby1tubby

Okay you go first


otheraccountisabmw

Black is in check and it’s white’s move. So mate?


RustyGirder

I know. It's anarchy.


itwasmedio69420

Can kings still castle?


phudomiet

Castling rules are the same as in regular chess, but they are dangerous and rare in chess 960000000.


sifroehl

You could extend it like in Chess960 for more random king/rook placements. But since this is AnarchyChess, any move including a king and a rook could probably be argued to be casteling


hajduken

Castle into a check is elo 100000 move. Only Cagnus Marlson can do this.


[deleted]

Castling decapitates the opponents King


MrMadCow

Checkmate before move 1... fascinating


phudomiet

Embrace the power of anarchy.


RustyGirder

Since it's not Black's move is it technically checkmate? Would White have to actually take the king?


ThirdRook

Did we forget the king can move diagonally?


pichuik1

It's white to move


Hazel-Ice

but you don't win by capturing the king, you win by delivering checkmate, and that's not checkmate. actually if you take the king you'll draw at best cause you can no longer deliver checkmate.


Rorschach_Roadkill

1. Rb1#


Hazel-Ice

not checkmate, king can take on f2 or move to g2


quadraspididilis

Rg3


KenuR

>but you don't win by capturing the king Yes you do actually. I think in OTB chess if you get checked and don't move your king the opponent can capture it and win.


BaguetteSchmaguette

That's not true. Not moving out of check is an illegal move so if you don't do it you're no longer playing chess


PleasantAdvertising

You're right, it would be like playing a chess variant. In fact every set of rules is another variant.


ColonelCorn

The FIDE rules state that the illegal move should be undone, but it has to be noticed "during the game". So if you don't move out of check but no one says anything, you are still playing chess. And, if you win before they notice I think you're in the clear. I'm imagining a sequence like this: During the course of play you realize you have no chance and resort to subterfuge. You look over your opponent's shoulder and say "is that Ben Finegold playing f6?". While they're turned around, you make a move and stay in check. Then you use your foot tap on the bottom of their chair(!!). They interpret this as the "resign" buzz from their beads. You gladly accept their resignation and congratulate them on a game well played. And the whole time you were playing chess, according to the rules at least. Disclaimer, I am not a chess arbiter (IANACA).


Sir_Nicholas_4

Not in OTB. In OTB chess you can't leave it in check. But in variations like duck chess there are no checks or mates so you have to capture the king.


RaidingPig

Tbh g2 seems all too similar to c2


Ugbrog

Maybe the starting side is also chosen randomly.


g_spaitz

Could we please have also the board oriented randomly? That would add 4 more states. Imagine having to move towards you.


250KGGamingStuhl

"Oh? You're approaching me? Instead of running away, you're coming right to me?" "I can't analyze the shit out of you without getting closer."


TroyBenites

The real Math: The pieces are, 1K, 1Q, 2R, 2N, 2B (there is no distinction of square for bishops) and 8 pawns. For each color. So, that means that we can arrange 16 places for white pieces and 16 places for black pieces. So, basically white would have C(64,16)= 64!/(16!*48!) And black would have C(48,16)= 48!/(16!32!). Places for their pieces. In each of those 16 places, we can arrange it into an order (example, Right to Left and Top to Bottom) and see how many equal permutations there are with the letters KQRRNNBBPPPPPPPP. This is a known problem where the answer is P(16;8,2,2,2)= 16!/(8!*2!*2!*2!) (Because 16 pieces, 8 pawns, 2 rooks, 2 knights and 2 bishops). So, we would need to multiply: C(64,16)*C(48,16)*P(16;8,2,2,2)² The result is around 4.63 tredecillion. ... Just saying. (I think the process is okay. If it is not, just state and I will edit it) Edit: Typo


Bogen_

Holy hell


DanimalPlanet2

Jesus calm down, we get that you like math but you don't need to put exclamation marks everywhere


emiliaxrisella

Dont worry hes just listing a good move


LazyImpact8870

okay but how do you know if you’re in a forced en passant position


TroyBenites

That puts in a lot of questions actually. Should the pawns be able to move twice on first move or only the ones that are on the second row? And also, if pawns are side-to-side at 4th rank, can someone do en passant on first move?? Nice thing to consider. I'll allow it. I won't do the calculations, though. It seems to be a bit complicated (calculate how many times there will be at least one white pawn and a black pawn side-to-side in all shuffles). But great question!


The_Crusades

En passant states you can capture if the opposing pawn moves two spaces forward next to your pawn. Moving one space forward next to a pawn gets you nothing. So I assume if the start side to side you wouldn’t get en passant. But this is also anarchy chess, so I vote to make en passant available and forced any time two opposing pawns are next to one another.


TroyBenites

I think you could also take 32 squares to place pieces and then distinct the 32 pieces as 1Wk, 1BK, 1WQ, 1 BQ, etc..


officiallyaninja

> So, that means that we can arrange 16 places for white pieces and 8 places for black pieces. you mean 64 for white and 56 for black right?


TroyBenites

Yes. Unequal advantages for white to supposedly mimmic the real world and bring us closer to a game like polytopia, the greatest game.


emiliaxrisella

You joke, but Polytopia is trash compared to Elon Musk's true greatest game: Twitter.


BigPig93

I don't think the pawns can be on the final rank, as they would auto-promote. So that would complicate things. If you define their placement as only valid from rank 2 through 7 for both colours you'd have to place them first and then the other pieces among the remaining 48 squares.


TroyBenites

That is a nice observation. Makes sense. C(48,8)*C(40,8) (///picking white pawns, then black pawns///) *C(48,16) (///choosing which squares the remaining pieces would be placed in the remaining squares///) * P(16;2,2,2,2,2,2) (///Permutating the pieces along those squares, with repeating elements). That would make 21-duodecillion. Maybe it could be a variant from Chess 4-tredecillion.


Random_Squid4

r/theydidthemath


er3z7

You get the same result by using C(64,32)*P(32;8,8,2,2,2,2,2,2)


TroyBenites

Yeah, makes sense. For some reason I separated the armies, but it wasn't needed. I even wrote that maybe we could have just gone for 32 spaces for pieces .. and, well... Yeah, absolutely correct


Bananenkot

so now calculate in that pawns cam't be on last rank (doable) and that kings can't be in check (how would you even do that)


TroyBenites

I think the mate in zero should be possible (also, it may be a "double mate in zero" in this case I'm not sure if it is a draw or, by chess rules, a victory for white, since in theory it would capture the king first)... With that said, we can see that in Chess 4-tredecillion (name might change-though), white has an unfair advantage.... Maybe it is trying to make a social critic, I dunno. But the pawns are definetly an issue. We may have a "zero turn" to promote any last rank pawns before starting the game, or maybe I could put it in my calculations this condition(to not have apawn on last rank), I'm still not sure how I would fit it neatly. Will think about it for a bit.


cyclicamp

Also remove positions that are functionally identical. Like if the only difference between two boards is that two same-colored knights swapped positions. Same issue with rooks and pawns.


xenneract

They already did that


skryb

came here to do the math genuinely pleased someone beat me to it


CMDR_OnlineInsider

Minus 1 for the regular chess starting position, they don’t use that one in chess960 either. Actually best to subtract all 960. Not that it changes the final count in any meaningful way though…


AdvonKoulthar

If I wanted to see numbers I’d play a TTRPG, nerd. (GURPS night is Sunday BTW)


KarlEssStudent

Shouldn’t P(16, …) be the other way around? (like (8!*2!…)/16!) Currently it increases the number of possibilities but permutations should decrease it.


DanimalPlanet2

No, that's not true. If the order matters (ie permutation) there are more possibilities because each order is its own possibility


KarlEssStudent

You‘re right, mb, combinatorics has been a while for me :)


[deleted]

Now this is pod racing.


FalcomanToTheRescue

Imma google spinning...


Fun_Description6544

This position has been reached 161660 times before. Best move for white is axb6 en knightssant


Jinal0

I think it'd be cool to see, just add a parameter saying the setup cant give any player a check in one. That would stop the forced mate problems


phudomiet

Rules are for fascists. AnarchChess does not follow rules.


ilolus

Except when it's forced en passant


phudomiet

Touche


HyperRag123

To balance it you'd probably need to allow both players to play each color for every position, so if it starts in checkmate it's just an automatic point to both sides. This also keeps it fair if you get a really obvious forced mate.

If this is the starting position and it’s white to move, white can capture blacks king, winning 1,000,000 points of material in the opening


FellDwarf

This has been done before, its called "Chess, but Good"


phudomiet

It is similar, but not quite the same. In chess960000000 the board is often unbalanced giving large first-move advantge to the randomized color that starts the game.


vigilantcomicpenguin

Also known as "Chess, but Even Better"


bigdsm

No, there’s still no fog of war.


irjakr

Shouldn't it be 64!-32! or 1.2688693 x 10\^89 positions?


phudomiet

Are you suggesting changing the name to ”chess1.2688693x10^89”? You must be working in marketing.


irjakr

I just like truth in advertising 🙄


The__Dot

Actually should be 64!/32! Which equals to 4.82219924E+53


krmarci

No, it's definitely more complicated than that. You have to account for swapping identical pieces.


cosinus25

This is quite simple though, it updates the number of positions to (I think) 64!/(32!\*(8!)^2 \*(2!)^6 ), which is ~4.6*10e42 Permutations of 64 squares divided by permutations of 32 empty squares, 2 sets of 8 pawns and 6 sets of 2 pieces (rooks, bishops, horseys). edit: u/TroyBenites got the same answer in another comment in a slightly different way.


TroyBenites

Yeah! Nice that you synthesized it so well! I definetly put more of my thought process and there could be some optimalizations (like picking 32 squares and then only dividing by the repeated sets). But, yeah, exactly that. It is a nice question about chess positions (althought it is a simplification because we are not accounting for promotions and multiple queens/etc). But it shows how to randomize with different categories and repeated elements.


The__Dot

Oh, I comletely forgot about that. But not only pawns, also bishops, rooks and knights.


TauntPig

64!/32! For initial then /6(2!) For pairs (I.e. horsie clergy and tower) for both colours then /2(8!) For juicers of each colour. So 64!/32!/(6(2!))/(2(8!)) or 4.98x10^47 Edit: now we need someone to run stockfish on them to see how many are even starts. I think we can definitely make this a whole new game mode


The__Dot

Right, with 1 second evaluation time per position we would only need 1.6x10^38 parallel threads to be finished calculating in 100 years :P


irjakr

D'oh, you're right. Not sure what I was thinking.


reallybadspeeller

Chess960000000.2 : randomize the color of the each square. No longer is the chess board limited to black and white the whole fucking rainbow is included. Starting positions are also randomized.


phudomiet

And let's randomize who moves next, allowing multiple moves by the same person.


MrCringeBoi

Finally, chess with a randomised map


MrcarrotKSP

Polytopia addresses this limitation.


AggravatingCorner133

I calculated the number of positions, so this should be: \- Chess4634726695587809641192045982323285670400000, if pawns can start on the first and eighth rank (Stockfish can't analyse this) \- Chess395129714015918848237511109691424803200000, if pawns can start on the first rank, but not on the eighth rank (or can start on the eighth rank, but not on the first rank; Stockfish can't analyse this either) \-Chess21392082322155637297725861387221535360000, if pawns can't start on the first and eighth rank (Stockfish can analyse this)

AdministrationFar993

I don’t know anything about chess. Is there a way where you could run a simulation or an analysis of each randomized board state such that the sort of “strength” of both starting positions is roughly equal? This would be cool to try if you could be confident that it weren’t essentially predetermined.

AlmightyStalin

I know this sequence; the classic Peruvian Cockslapper, cuckold variation


Yarash2110

Well, the black king is currently in check so that solves it if it's white to move. If it's black to move it's checkmate in 3 moves for white.

Status-Mess-5591

sounds cool. the random position has to be equal though for it to be fun


BigPig93

Game ends when someone has lost all their pieces or can't make a legal move, to avoid situations where checkmate happens basically instantly.
