Basic Knightmare Chess Endings #6: The Heir 02/03/2018

20180203_205836-1-1The game-changing cards in Knightmare Chess come with maximum card values of 10. I have a feeling Heir* from the Knightmare 2 set is worth more than 10.

The defensive power of Heir is incalculable, because an heir’s presence allows you to ignore check

If I played a game of Knightmare Chess with a deck limit of n*10 points, I’d consider a deck of n Heirs, and perhaps expect to be accused of exploiting overpowered cards.

The offensive power of Heir is excellent. We generally consider the king’s mobility equal to a knight’s mobility — both pieces move in straight lines (if you don’t see knight moves as straight lines, learn that) of eight directions, but the king is limited to one square, while the knight  moves two squares distant but only to opposite-colored squares (twice the range, half the square color).

However, the heir’s compact movement improves on both the knight and the bishop for close fighting. The knight can be attacked from any square around it, while the bishop can be biffed from the adjacent opposite-colored squares.
In other words, the standard minor pieces are vulnerable at closest range, but the heir is rock solid. In fact, the heir’s mobility makes it possible to checkmate the enemy king with king plus heir. Usually, the minimum amount of force needed to checkmate the king is knight-plus-bishop (they cover each other’s weakness):


But the heir  is as good as a queen for checkmate.
The checkmating procedure is ridiculously simple: Draw a five-square corner around the enemy king, and every time the enemy king moves, redraw the cornering pattern accordingly.
I don’t have to find another symbol to stand for the heir, since their abilities are exactly the same — they are both kings, and are  both heirs.
