Chess/Knight

The knight in Chess moves in a limited form. Each separate move may be visualised as stepping exactly one square horizontally or vertically and then one square diagonally away from the direction of the original cell. There are four possible choices on the first step, and for each such choice two possible diagonal continuations, resulting in eight possible moves for the knight (unless the knight is positioned close to a border of the board, in which case some of the moves will be impossible).

• The knight is only limited by its sister pieces on its target cell.
• The knight is not obstructed by intervening pieces, it can move even when completely surrounded.
• The knight captures by replacing the opponent's piece on a destination cell.
• Tip: the knight is the only piece that can be in position to attack a queen without being in the queen's line of attack, making it useful to threaten the queen at the same time it threatens another piece, especially the king, forcing a sacrifice. This technique is known as forking.
