There are four knights who are about to do battle.

RED (R)
BLUE (B)
GREEN (G)
YELLOW (Y)

Their world consists of an 8x8 square Arena which looks suspiciously like a chess-board. The Arena is surrounded by water on all sides. The 64 tiles on the board are identified with (row, col) co-ordinates with (0,0) being the top left tile and (7,0) being the bottom left tile (row 7 col 0).

Each knight starts in one corner of the board.

R (0,0) (top left)
B (7,0) (bottom left)
G (7,7) (bottom right)
Y (0,7) (top right)

Around the board are the following four Items and Positons:

Axe (A) (2,2): +2 Attack
Dagger (D) (2,5): +1 Attack
Helmet (H) (5,2): +1 Defence
MagicStaff (M) (5,5): +1 Attack, +1 Defence

Each Knight moves one tile at a time in one of four directions.

North (N) (UP)
East (E) (RIGHT)
South (S) (DOWN)
West (W) (LEFT)

Each Knight has a base attack and defence score of 1:

Attack (1)
Defence (1)
