Connections and shapes · Lesson 10
Extensions, diagonals, jumps and knight’s moves
A stone directly beside an existing one extends it, often called an extension or descent. A diagonal neighbor is a small diagonal move. Leaving one empty point between stones makes a one-space jump; a knight’s move spans the diagonal of a one-by-two rectangle.
An extension connects immediately. Diagonals, jumps and knight’s moves do not; they travel farther with fewer stones but leave entry points for the opponent. Look around before choosing how solidly or quickly to develop.
A two-space jump reaches one point farther than a one-space jump; a large knight’s move reaches farther than a small one. An elephant’s move spans the diagonal of a two-by-two-line square. Recognizing the shapes is enough for now. Their names alone do not judge a move, and rotating the board does not change the relationships.
