1. "The Elevator" or "Liftul" in the Romanian language, is a fairy condition, its representation is reassembled
by indicating the chess board columns, from "a" to "h",
which the white and/or black pieces are positioning to change or
lower and position.
In a chess problem, there may be at least one
column called generic "elevator" and no more than seven.
These columns, called "elevator", are not allowed to have
any other white and/or black pieces that prevent the moving pieces
from being moved or lowered to make a move.
Moving a bishop onto a
column called "elevator" will not allow him to change his
color, he will retain the color of his original square.
The
problemist will have to avoid the duals obtained by positioning the
pieces on several fields of the "elevator" column.
"Zero positions" and other fairies conditions are allowed.
"Zero positions" and other fairies conditions are allowed.
2.
It is forbidden to capture the pieces along the column. The
pieces that can not be captured will be considered buffer pieces.
In diagram 1,
after Sc3-b1 and Bd3-b1 is forbiden the capture of wPb6. The Sb1 and
Bb1 dont go up to b7 and b8 because the wPb6 is a buffer piece. Are
legal move only Sc3-a4(d5)-xb6.
