CRAZIEST CHECKMATE EVER

Kwolverine04

Can you solve a puzzle that looks impossible? Try it. Hey, it's a Mate in 1 according to the great Adolf Anderssen. Stockfish can't find it, I tried. So, can you? If you want to solve the Mate in 4, then try to do the actual puzzle.

I just looked at every possible move, that is not a mate in 1.

Like I said, chess.com does not recognize it as a move. The problem is, at this time the rules of chess were a little different. There was no rule prohibiting this move like there is today.

Yeah. It's a mate in 4, because stockfish doesn't recognize the mate in 1.

Clever. Yeah, this explains why Stockfish did not solve mate in 1. The rules of chess programmed into Stockfish simply do not give promotion to an opponents' piece as a possibility. Meanwhile, Grandpa Blunderoo is going by a different set of rules. When was this rule change implemented? Around 1700 or so? Maybe Grandpa Blunderoo has not played chess in a while: he might remember the old rules wink.png

Upon checking briefly, I think the "rule change" referenced to here was in 1863. I am not certain of the exact year, but the Wikipedia article on promotion (history of) sounds like 1863 was the year this ruling changed (for not promoting to an opponents' piece/but many similar rule changes regarding promotion have also occurred over the years).

It WAS a ++....cuz when Adolf made it up ?....it was LEGAL to do this up until 1862 - to choose which piece u could promote !

Absolutely correct!! So I guess this forum is useless now.

Well Kwolverine04 it would hardly be useless; after all it taught a little history of rulings. I don't expect too many more comments to be posted now that the "mystery element" is more or less gone, but I found this forum somewhat fun and certainly useful happy.png

I have seen this before. Still it is good. I would have answered it if I was early

Let's make this forum: Find the Hardest Mate in 1! That way we can keep it going!!

Kwolverine04

So, if anyone has a hard M1 they want to share, post it here plz!

Why do I feel it is only a matter of time before someone posts a position from Black's perspective when you are White ... that seems to be the trick for half of the "near-impossible mate in 1 problems" I encounter. By now I always just check the chess board orientation before I look at these "hard mate in 1" problems.

number-0

you can IF YOU turn the pawn into a black knight but like you got to mention that you can make the promotion into any peice you want

Kwolverine04

this was a game I played earlier today with my brother. Move 50ish

Can you see the forced mate I missed? Hint: 9 moves.

Kwolverine04

Two more checkmates: First one is white, Easy mate.

Second one same position... But it's BLACK to move this time!! Mate in 7, doing best moves according to stockfish.js 9.
