When you take lateral (sideways) relief from an unplayable lie you measure your 2 club lengths from the edge of the unplayable area don’t you?
Sorry – the 2 club lengths is from the position of the ball. If you are in the middle of a big bush you might need to take 2 club lengths sideways, drop the ball and then take another unplayable lie. The practicalities of measuring and dropping inside a bush aren’t always easy though – don’t forget that back-on-the-line and stroke and distance are also available options.
