In the year 2001 it was the first time I improved the worldrecord for longest checkmate with mate in 267 moves . Have a look at  the second diagram :

Between 2001 and 2022 I improved my own worldrecords for longest checkmate many times :

Insane.

Thats not long at all, i saw it from move 1 cmon

b4 b1=Q

3.b4 b1=Q

2 dark squared bishops is possible but a pawn needs to promote into a bishop

crazy

This mate in 292 is cooked and ends up being a mate in 42 (or less):

what the hail.....

HUH?!

Yes it's not real. Only 7 men EGTB exist.

doing this for an achievement

Can you post a pgn? It's a bit long to remember.

I think you are referring to a different puzzle than I am. I'm talking about the mate in 292 by Blathy and you are talking about the mate in 290 by Blathy.

Well, you need to tell me what move you think is the "mistake" for Black.

Sometimes it repeats moves
