Double Corner Squares
Checkers Fundamentals Double Corner:
Double corner squares are one and five squares.
Twenty eight and thirty two are the other side
double corner squares. Before commencing
to play checkers online, it is important to
understand the numbered checker board and the
checker move notation.
Checkers is played on the dark squares of an
8x8 checker board, where only 32 squares of
the 64-square board are used. The board is
positioned for play with dark squares in the
upper left and lower right corners. Traditional
notation numbers the
squares 1 to 32 and only these squares may
be occupied by checker pieces (see Diagram
1). With Black at the top and White at the
bottom, the board is numbered in rows from
left to right and top to bottom. These numbers
are used to indicate the player’s move.
A move is annotated by indicating the source
destination “to” squares
of the checker moved, separated by a hyphen.
For example, if Black makes a starting move
11-15, then this indicates that Black moves
the checker on square 11 to square 15. A semi-colon
is given after each white move.
Fundamental captures are shown in the same
fashion by a hyphen or an ‘x’,
so if Black jumps 15-22 or 15 x 22, then Black
jumps the checker on 15 over to square 22 and
captures the White checker that would be positioned on 18.
Fundamentals of multiple jumps require greater
attention as the notation is to show the start
and end squares only. The squares between the
jump are not shown so that the notation of
1-3 would mean that a King double jumps from
1 to 10 to 3. However, the intermediate square
10 would only be shown should there be two
ways to jump and this would not be clear otherwise.
Diagram 2 indicates the starting position of
the checker pieces. Each player uses 12 playing
pieces, checkers or men. The dark checkers
are placed on squares 1 to 12, whereas the
light checkers occupy squares 21 to 32. Understanding
the layout of the board will help your checkers game.
a) The two single
corner squares fundamentals, square 29 to square
4, create a long diagonal known as the ‘single-corner
diagonal’ and this has been dubbed
the ‘D(defensive)-line’ by
double-corner squares’ fundamentals
is listed as squares 1, 5, 6, and 9, whereas ‘White’s
double-corner’ is listed as squares 24, 27, 28, and 32.
c) Dark squares
fundamentals 4, 8, 11, and 12 are called ‘Black’s
single-corner’, whereas light
squares 21, 22, 25, and 29 are called ‘White’s
diagonals fundamentals’ refer
to the two diagonals stretching from square
1 to square 28 and from square 32 to square
5; squares 28 and 32 are one double-corner
and squares 1 and 5 are the other double-corner;

Checkers Squares Fundamentals
Even though a checkers fundamentals standard
game is played on the dark squares, checkers
are often placed on the light squares in
many checkers diagrams to enhance readability
only. Also, the official colors for the checker
pieces are red and white, though older sets
may contain black and red game pieces. In
this instance, the black checkers are called
the red pieces are called ‘white’.
That’s just the way of Checkers. Some
abbreviations are as follows: RW = Red wins,
WW = White wins, * = the only move to win
or draw, PP = published play. The following
annotation symbols are used to describe checkers plays:
move follows indicates an excellent and potential
winning move indicates a poor move or one that
potentially could cause a loss!
an interesting checkers fundamentals kind of move.
a questionable move. In published works on
Checkers, these symbols will be used when
explaining or listing various game plays.
It is important to understand their meaning
when first learning the fundamentals of checkers online games.
