By the rules, is an object ball deemed to be frozen to a cushion if it is so close that it appears it might possibly be deemed to be in contact with the outer fuzz/nap of the cloth textures, even if it’s not fully and clearly frozen on the rail? This came up yesterday in one of our big tournaments, where I was called in to make a ruling, and as hard and close as I looked, it was still very hard to determine. I ruled it was frozen, since it looked to me like it might have been barely touching some of the outer fibers of the rail cloth.
