Triangle Chess Invented by Derek Nalls in November, 2000. Implemented by Derek Nalls and Jens Markmann in November, 2000. There are 12 directions of geometrically-contiguous movement available, at every increment of 30 degrees.
Draws are nearly impossible.
Knightriders and empressriders are NOT leaping pieces upon the triangular-spaced board. Instead, they move without skipping any spaces as true sliding pieces. No pawns, bishops or queens are used. Development is faster, more dangerous, less tedious than with standard chess. The theoretical depth is NOT disappointing.
