In this position almost any move order will finally stop white from playing
d1d2,d2d1 because checkmate ends the game :)
In principle your program should avoid pawn chains against humans.
If your program plays for example 1.e4 c6 2.d4 d5 3.e5 (no book of course) or
1.c3 e5 2.d4 e4 then there is something wrong.
