Ok. this means that the computation of the ep-square
is not just "the square behind a doubly-pushed pawn"
but "the square behind a doubly-pushed pawn only if
there are side pawns that can use it and performing
that ep capture isn't going to put the opponent
king under check".

This is going to slow down double pushes quite a bit;
I wonder if there is an easier solution...
