The Longest Forced Checkmate I've Ever Seen! 

I am somewhat skeptical about the possibility of that board appearing in a real game. there are at least 13 pawn captures out of the 14 total captures for black's position. and all of those must be in the correct direction. not to mention the queen capture by white and the promotion of one of the center pawns so the game probably needs to be played with the specific intention of reaching this position and even that would be nerve-wreckingly difficult.

Takes an absolute madlad to put their rook in front of a literal column of pawns too lol

Those forced checkmates are prevented by the 50 move rule

Also if you even watched the video you would’ve seen pawns moved which reset the 50 move rule

@@boevoikrikun lol

hello

How +8 means there's forced checkmate

I don't think the engine has 130 depth.

@@onethegogd5783 if there is a checkmate it just says M any number

@@kirillzakharov7336 thats what I'm saying huh

Hello, I have made a chess engine so maybe I can try to explain. Chess engines have a limited range for how far they can see because the number of possible positions grows exponentially. Looking 130 moves ahead would require looking through too many positions. Because an engine cannot look ahead an infinite number of moves, the engine must use an algorithm to guess how good future positions are to determine the best move. The evaluation of a position such as +8 or -4 is the engine’s estimation of how good the future position will be assuming the best moves from each side up to a certain depth. Chess engines will say forced mate exists only if every response by one side always will lead to an eventual checkmate. Because the engine cannot look ahead 130 moves, the engine cannot assert that forced mate exists. Eventually, the chess engine will detect the mate. For Stockfish, this is probably around 20 moves away from checkmate. If you have an interest in building or understanding chess engines, I encourage you to take a look at the Chess Programming Wiki. It is a very useful and informative resource and it may help you understand how engines work if my explanation was insufficient or confusing.

The black pawns need 13 captures to get to the sides like that. 12 of the 14 missing white pieces had to be taken by pawns to help them reach the side, the c and d pawns can't be taken in a way that helps so one of those white pawns must actually have promoted and the promoted piece taken by a black pawn to give the 13th capture necessary. History doesn't record what happened to the final lone white pawn....

@@mattc3581 They didn't have to be promoted they could have captured the queen or darksquare bishop to change the file they were on

@@violetasuklevska9074 good point forgot black was missing a couple of pieces as well! I think both of the black pieces would need to have been taken by white pawns in order to either move two of them across one file or one across two files to position them to enable blacks pawns to get where they need to go, but as you say that is another possibility.

Chess simp?

If you have a link for it it would be cool to share so others can see it!

That's nothing compared to the mate in one million moves I recently saw in a blindfold simultan against the other 500 children in my kindergarten. I could easily calculate a million moves, but both my opponent and me agreed to a draw, because it would have taken too long for us to play so many moves. Regardless I am very proud I have seen the mate in one million moves even when playing blind. That might make me the strongest calculator in this comment section.

"Thats so easy chat, how did he not see it?" 😂

Stockfish actually does know, it is a draw, you don't play a6 first, you move your other pawns first, and then when your last pawn is about to promote, you play a6, which stockfish deems a brilliant move and then it's a draw

Yesterday I was playing a game that I had to do a lot of those queen’s dance moves, it was very counter intuitive when I started playing chess

but probably not legal because of the 50 move rule...

depends on if there is a pawn move or capture

@@vinesthemonkey There isn't.

@@vinesthemonkey Like just think about it if its a 7 piece tablebase endgame and all 5 pieces other than the kings are pawns, you could stall to 250 moves (50 moves per pawn). So no.

bro you know one pawn can move more than once right? every time it moves it resets the 50 move counter

it resets after capture aswell

@@attilaseyfullah8522 yeah, knew the capture rule, wasn't a were of the pawn move rule

This problem is not to be judged on its practical value. It was constructed in order to set a record for a task. In this case the task is to construct the longest possible directmate problem where White has only king and queen. It was composed in 1955 by J. Halumbirek, who constructed it by adapting the matrix of a problem by that master of chess task problems, Otto Bláthy.

I’m pretty sure this puzzle was not created to symbolize a chess game, and guess what, to maybe, just maybe, to set problem where the goal was to compose a legal position with the longest forced mate sequence
