A preliminary table of records in 24 categories was prepared with 97 compositions (95 originals).
A total of 226 problems were submitted for the competition, with many versions. That's why mistakes are possible.

The judge's (Dragan Stojnić) rating, award and his view of this competition will be published soon.

Thanks for the work ... there are some really interesting schemes.
For rsq-B we found this, also with one move of the black king:

(= 7+5 )

ser-h=8
1.g1R 2.Rg5 3.Kf6 4.ed1S 5.Sc3 6.b1Q 8.Qf8 gf8B=

A setting in 7 moves seems to be impossible for this combination.

Yes, I plan to publish, in addition to the record tasks, other interesting works such as this (MPID: 117) - joint problem of Frank and Michael

(= 5+7 )

Probably my best attempt with an imprisoned instead of captured black queen.

This could be a separate category:
“Mixed AUW with the BQ in the final stalemate position”
Your problem (mpid: 27) was also repeated by Anton Baumann (mpid: 148)

 QUOTE

I got 6, but with the black king in check and a promoted black bishop, and 7 with the black king in check. But 8 seems to be impossible. Perhaps change knights to camels or to nightriders...

@(43) rsq-B 7-12-31
I've got this one also with bK move:
(= 8+4 )

ser-r=8

1.b1R 2.Rb3 3.Ke6 4.fxg1S 5.Sxe2 6.g1Q 7.Qg6 8.Qe8+ dxe8B=

I like the task by Manfred (bqs-R : 7-15-40). Although it has 40 points it's very nice play. I tried to save some points but without any success. My best position is this:
(= 10+5 )


But no pieces or points are saved. Perhaps this position is slightly better because it's a nicer stalemate. All squares next to the bK are guarded only once in the final position. Also there is a better usage of the wQ because it's pinning bS in the final position.

Miodrag wrote in (39) that he found the same position as I did for qbr/S-6-12-20, but it seems to be missing from the records table.

Joost, this is your task only. I found this position after Dragan published information about the tasks without diagrams. However I did not submit this problem by the deadline 1.12 so this is your task only. Congratulation for finding this excellent task in 6 moves! I think this is the most impressive task because there were no other problems in 6 moves. I think this is the only group where only 1 problem with the minimum number of moves is created.

It's easy to compose when the goal is known. It's much harder when you do not know what is the task. That was the point of my post.

In my opinion, Joost's problem is an absolute winner.
His position is at least one move better than the others in that category.
There is no such example in other categories.

Many tasks from different authors are either identical, with a mirrored position, or have the same solution.
Such problems can be considered a joint composition of two or more co-authors.

So all records can be presented like this:

Ser-h= tasks showing the mixed AUW in the fewest number of moves (with secondary criteria: less number of pieces and less power of pieces) in 24 (+ 1 additional) categories

https://matplus.net/pub/Ser-h-patt_MixedAUW_records.pdf

It will be interesting, if it is possible to improve some of these tasks.
Or they remain for all time!
Site Matplus is open to improvements, and this file will be updated immediately after a new record.

@54

About the problem 25 from this post. This is very nice problem but I think it should not be in this list of tasks. I had this postion but since I found the postion with two points less my name is not in the list of authors. If I remember well we were asked to send the tasks only. So it does not make a lot of sense to list this as an achievement. By the way I also have the problem from this category (mpid 43) but since the promotions are in a different order it's hard to compare them. But it's also possible that some other author found my position but did not send it because they found a better tasks.
