I see that we now allow textures in non-BLD events, 3d) Puzzles must either have coloured stickers or coloured tiles or textures. However, 3j still prevents them. 3j) Puzzles must be clean and must not have any textures, markings, elevated pieces, damages, or other differences that distinguish one piece from a similar piece. Seems like if we now allow textures on different faces, 3j should be eliminated completely.

3j does not prevent textures as long as you can't distinguish one piece from a similar piece.

[quote="MadsMohr":1blftgcu]3j does not prevent textures as long as you can't distinguish one piece from a similar piece.[/quote:1blftgcu] But looking at the change log, Ron's meaning for textures here to be allowed for blind cubers to compete in the regular speedsolve, so distinguishing the pieces must be done. In the 2009 regulations, everyone would have agreed that you shouldn't be able to feel the difference between a blue/red edge and a green/red edge. But if the textures are meant for the blind, then you must be able to tell the difference between the blue/red piece and green/red piece, but you shouldn't be able to tell the difference between the red side of the blue/red piece and the red side of the green/red piece. Also, the statement in the BLD section about not allowing texture here should be changed to not allowing different textures.

Is there still a textual problem? Regarding blindfolded: Blind people should memorise on a textured or similar cube, but solve on a non textured cube. Theoretically there could be a textured cube that has same texture on all sides, and that cube would not be allowed in competition because of the current text. I do not think that is a problem.

I would write them as so: 3d) Puzzles must either have coloured stickers, coloured tiles, or textures. 3d1) Puzzles using textures must have different colors on each face to aid in scrambling and judging. 3j) Puzzles must be clean and must not have any markings, elevated pieces, damages, or other differences that distinguish one piece from a similar piece. B1d) Solving phase must be done on a puzzle with tiles or stickers, without [b:30jb0c8x]different[/b:30jb0c8x] textures or markings. 3d1 makes sure someone can't compete with an all black cube that has different textures. I'm guessing a blind person can distinguish some textures easier than sighted people. Verify the scramble and solve could be difficult. 3j removes "texture" altogether, since we allow different texture on cubes to distinguish the pieces. B1d clarifies that the texture must be uniform, since you can't have a solid that doesn't have texture. Smooth or rough, texture is always there.

I agree with Bryan's suggestion. Ron, your most recent message makes it sound like it's clear to you what the right thing to do is for a textured cube with the same texture on all sides; perhaps it's a language barrier thing, but I can't tell whether you think such a cube would or would not be allowed according to the new rules. And Bryan is right that every cube has a texture - there's technically no such thing as a non-textured cube. I hope that uniformly textured cubes will be allowed, and the easiest way to allow this is to do as Bryan suggested, change B1d) to: B1d) Solving phase must be done on a puzzle with tiles or stickers, without [b:soe6l7zy]different[/b:soe6l7zy] textures or markings.

Bryan/Mike: Thanks for helping a non native speaker.
