[Retros] Initiation to PGs + brute force

[Eric Angelini]

Many thanks, Alain !
I was wondering, seeing the "at home" examples, if
brute force has already being used to check all "at
home PG" positions where:
1) only one pawn is abducted (16 possible configu-
   rations to be tested)
2) only two pawns are abducted -- one White and one
   Black (64 tests)
3) only two white pawns are abducted (28 tests)
4) only two black pawns are abducted (28 tests)
...
k) three pawns
...
n) one pawn, one knight
...
x) four men
...
Best,
É.
