Who wins from this (Puzzle)?

Many people read these threads, so it's not surprising to find a wide range of attention spans among the various readers.

Since 2001 ALL worldrecords for longest mate-compositions are from me . At youtube you can see the whole evolution until mate in 553 moves in 2016 . Have all a nice day with chess , but I think the game GO is more interesting than chess . https://www.youtube.com/watch?v=bqnq580ozAI

As wikipedia says, RBN can often draw by trapping/capturing/ or exchanging the opposing knight, or use these and other threats to force move repetition.

The actual worldrecord for longest mate compostion is mate in 595 moves .

Try to improve my worldrecord if you can :

What I am confused about is the relationship between the current world record "mate-in-595" and the "mate-in-553" from 2016. These records are too far apart to be of the same type. You can't just extend 553 to 595 unless these numbers refer to different record types or start from different tablebase record position. Retracting 42 more decent moves from the same position to jump from 553 to 595 moves is an impossible task - IMO. Can you explain?

how tf is this forced mate

i cannot comprehend

Yes , the worldrecord for longest mate WITH OBTRUSIVE pieces ( with UNDERpromoted pieces ) is my mate with 595 moves and the worldrecord for longest mate WITHOUT ANY PROMOTED pieces is my mate in 553 moves , but the worldrecord for longest mate WITHOUT OBTRUSIVE pieces ( with promoted pieces ) is my mate in 555 moves :

Thanks! I'll chew on that

In the mate in 546 thing the game would end in a draw via 50 move rule, so isn't it not really mate? Unless we're assuming this is OTB and no one claims a draw

You live in the world of game players but not everyone does. Some people love chess puzzles and they have rules for chess puzzles. They deleted the 50-move rule from their rulebook. It simply does not exist.

How is Q vs Rb basically always a draw, but how come QN vs RBN always a win?! All the other combos of queen and minor vs rook and to minors are drawn.

That turns out to be so for many endgames. Eg. K+B vs K is always is draw but K+R+B vs K+R occasionally wins. Add one more piece and things are even worse for the underlying party. K+R+B+N almost always beats K+R+B. Which seems illogical as the relative value of his material gets better for the underlying side with each addition (divide the points). Also the principle to exchange pieces when you are materially up no longer holds. It's a lesson we learned from the tablebases.

I have no clear explanations but for security I always keep a pawn on the board!
