Preisbericht (Gruppe 8 = "Rest") siehe feenschach 10/1990, S. 368.
Doppelte AUW in einem langzügigen Serienzugselbstmatt, da kann man nur mit Mutter Kempowski sagen: "Wie isses nur möglich!". Kein Wort, nur tief durchatmen und staunen! (Preisrichter Theodor Steudel).

Sc4+ Sxe2# mit Dualen (Arnold Beine)
Erich Bartel: Ein Wahnsinnsproblem!!! (2012-06-13)
Arnold Beine: Leider kaputt, denn am Ende kann man das Selbstmatt auch mit einem Batterieschach erzwingen. Die thematisch vergleichbare P1278403 hat aber gute Chancen, korrekt zu bleiben. (2022-10-22)

Henrik Juel: Popeye 4.61 with 'opt thr 1' found no flaws
Congratulations, James (2022-10-08)
msterkowiec: Strange, I seem to see #12 here ( kB1N4/2P5/8/2pRP2n/2P1P1R1/bBK2p2/pp1Ppppp/n4Q2 ) with 1.R:c5 for example like this: 1... b1N+ 2. Q:b1 ab1N+ 3. Kd4 N:b3+ 4. Kd5 Nc3+ 5. dc3 Nf6+ 6. ef6 f1Q/e1Q 7.c8Q etc. (2022-10-09)
SCHRECKE: Ja, NL in 12 Zügen: 1. Txc5 (Gustav 4.2b) (2022-10-09)
James Malcom: Thank you Henrik.

Strange, this usually never happens to me. This is indeed the position I sent. Yet I know I tested for Txc5. I made a mistake, but I forget how. In any case, Td5-d7 seems to fix the issue? (2022-10-09)
msterkowiec: Yes, in position #16 kB1N4/2PR4/8/2p1P2n/2P1P1R1/bBK2p2/pp1Ppppp/n4Q2 John Galt 4.6 finds no other solution but 1.c8Q.

BTW: here you can find a link to it: http://szachowe.pl/viewtopic.php?f=18&p=118120&sid=6e44d27ffcffe4cf867c23001ab11773#p118120

I write to be super fast and I believe it can save quite much time of chess composers...
(It's not a popular piece of software and Windows pops out quite many warnings about it, anyway it's enough to trust your antivirus) (2022-10-12)
Olaf Jenkner: The position Td7 is C+ (Gustav 4.2 b)
There are three full length variations. (2022-10-13)

Schade um das dualistische Matt. Im strengen Sinn also kein Rekord.
