I live on the Texas gulf coast and with all the rain lately, that means tons of casual water to deal with. The rule for relief of casual water, as I understand it, is you can go up to 5m back, no closer to the hole and on the line of play. What if you can't get relief going back 5m on the line of play? In that case, I have just been playing the nearest point of relief from the water, regardless of the line of play? Is that right or do I have to try to get as close as possible to the original line of play?
