Pieces can turn 45 degrees after movement. (8x8, Cells: 64) [All Comments] [Add Comment or Rating] George Duke wrote on Sat, Jul 19, 2008 07:29 PM UTC:Good ★★★★In Turning Chess, Betza's first example is Pawn 1 f2-f3 (turns right), 2 f3-g4 (right) 3 g4-h4 (no turn). That Pawn can never move again. Notice the optional ''turning'' after a move is always 1/8, same as saying 45 degrees. Betza postulates Turning Bishop and Rook having same value. In 2004 Comment Gilman takes exception that there is no such thing as Turning Knight, alleged by Betza within the article, and rather Knight turned logically becomes Camel. It leads Gilman in subsequent years to explore in depth all the angles involved for purposes of nomenclature, classification, and further invention of fairy-Chess-piece moving modalities.

Thus the Knight is unchanged by turning. With regard to Charles Gilman's comment, I must admit that I find the Camel uninteresting, both as a chess player and a mathematician. Charles Gilman wrote on Thu, Oct 14, 2004 07:53 AM UTC:'There is no such thing as a Turning Queen because all rotations are identical; it turns but stays the same. This is also true of King and Knight, and it means that they do not benefit from the value boost that true Turning pieces get.' It is not true of Knights as Knight moves are not at exact 45° intervals. Just as a 45° turn on the radials (i.e. Rook <=> Bishop) involves mutiplying or dividing distances by root 2, so it does with oblique dirctions. Thus a Knight making a 45° turn would be come a Camel (and vice versa). 3 comments displayedLater ⇩Reverse Order⇧ EarlierPermalink to the exact comments currently displayed.
