Few CVs have triangles. They work symmetrically for two-player .

correspondingly. All F.i.d.e. rules apply. Notice maximum Rook move is same 7 cells as in squares. Rook's path from corner 50 is 50-51-38-27-18-11-6-3. In these equilateral triangles, the return path is different, 3-2-5-10-17-26-37-50, with all the implications. Jonathan was on the right track at Spratt's Chess for Three:
