[Retros] 4 related pj's

[Nicolas DUPONT]

Dear retro friends;

I asked myself the problem of  constructing pj's in which a lign of pawns
"teleports" to another lign IN ORDER.

Here are the solutions that I've got (all are C+). I wonder if it's
possible to find shorter games (same thema) than I did  here.

Greetings;

Nicolas.
