play all play one stop play next play all
Nach den "alten Regeln korrekt", aber inkorrekt, wenn "dummy pawns" erlaubt sind:
1. Sg6 g1=B! "and White cannot possibly mate in two more moves."
von Pavitt als Beispiel dafür konstruiert, daß die auf dem Londoner Schachkongress beschlossene Änderung der Umwandlungsregel für den Britischen Schachverband (d.h. die Möglichkeit der UW in einen "dummy pawn") auch Auswirkungen auf die Schachkomposition hat:
1. Probleme, die nach den alten Regeln korrekt waren, können inkorrekt werden (wie dieses)
2. Da andere Schachverbände diese Regel nicht adaptiert haben, muß bei Problemen mit UW stets angegeben werden, nach welchen Regeln zu lösen ist.

Correct according to the "old rules", but incorrect if "dummy pawns" are allowed:
1. Sg6 g1=B! "and White cannot possibly mate in two more moves."
Constructed by Pavitt as an example of how the change in the conversion rule for the British Chess Federation decided at the London Chess Congress (i.e. the possibility of UW into a "dummy pawn") also has implications for chess composition:
1. problems that were correct under the old rules may become incorrect (like this one).
2. since other chess federations have not adapted this rule, problems with UW must always indicate according to which rules to solve.

s.a. Version P1372932
Henrik Juel: C+ by Popeye 4.61, except for double threat 2.Se5,Se7 (2020-02-26)
A.Buchanan: The defect for me is that the threat 2. Se7 is not separately shown in actual play. Compare: 1. Sg6 g1=D 2. Se5 thr 3. Sc4#,Sxc6# but both threats are forced separately by specific sD moves. (2022-01-26)
