[Retros] FENfun + computer

[Eric Angelini]

Hello Retro-fans,
a search by computer from someone
from the France-Échecs forum (see
the link at bottom of my page
www.cetteadressecomportecinquantesignes/FENfun.htm)
gives 2 diagrams for the "3" challenge
with 5.5 moves!


> Voici quelques résultats trouvés par ordinateur:


Mono-1: aucune solution en 9.5 coups ou moins, donc le minimum est 10.0 coups
Mono-2: le minimum est 6.0 coups (48 diagrammes possibles)
Mono-3: le minimum est 5.5 coups - nouveau record (2 diagrammes possibles)
r3kbnr/pp3ppp/n3p3/3pB3/3P3q/3Q3b/PPPKPPPP/RN3BNR
r3kbnr/pp3ppp/n3p3/3pB3/3P3q/3Q3b/PPPNPPPP/R3KBNR
Mono-4: le minimum est 8.0 coups (1 diagramme possible)

Waow!
Best,
É.
