Can I ask a related question please. When I play a shot I always stand behind my ball and look for a natural mark of some sort that will be on the line in front of my ball. On the fairways I don't think that there is a problem with this at all. My question is whether I can do the same in a bunker? I don't makes marks in the bunker to use for alignment but will look for a stone or something in front (and I do rake the bunker afterwards!). Could I be in breach as I might step on the intended line behind (even though I don't use it for my line, only I know my intention)? Should I instead just be extra careful to straddle the likely intended line so as to avoid any issues?
