Hi,
I find your site very vast and complete to the point that I consider it to
be my "Online Encyclopedia of Chess" for all my present and
future references.
And yet, I
haven't found any information in your site regarding a little
known Chess maneuver called 'Square area of Queening'. This
refers to the minimum square area needed for a Pawn to be able
to promote to Queen.
This applies to
King and Pawn endings only, of course.
Thank you.

Dear
viewer,
The square area of Queening is a simple
method to find out if a Pawn would be able to Queen in a King
and Pawn endgame by calculating whether the opponent's King can stop
a Pawn before reaching the eight rank or not.
Let's consider the following Chess ending position: fig. 1
shows a Pawn in square b4 and able to promote in four moves:
Fig. 1
Now, let's trace an imaginary square area
(fig. 2) from the current position of the Pawn to the Queening
b8 square or diagonally to the f8 square, in this case a 5x5
square area. If the Pawn and the enemy King are inside
this area, then the black King will be able to stop the
advancing white Pawn before queening, no matter who moves next.
Fig. 2
On this slightly different position (fig. 3),
the Black King is on g3 square and outside the square area of
Queening. If white Pawn moves first, it will be able to Queen
because each time the Pawn moves forward one square, the square
area of Queening shrinks (to 4x4) and the black King will never be
able to get inside this area.
On the other hand, if black King moves first,
it will enter inside the square area of Queening and can stop
the advancing of the Pawn.
