Thanks all for responding. It looks like we all mostly use, or rather don't use, strokesavers the same way. However perhaps my OP was a bit misleading on the question I was trying to ask, what I was really getting at was if you are on a hole and you don't have an inkling which way the hole goes (as per Daryl's examples), or whether it dog-legs left or right, or where the green is hidden, such that you are forced to refer to the strokesaver, has the architect done a bad job ?
To give one example, perhaps not the best but I recall playing Cruden Bay on the long par 5 (14th) and having hit two pretty decent shots up the fairway, I couldn't see the green or the flagstick. I knew I must have been less than 100 yards away and had to go for a walk about to try and find it. It turns out that with the course being fairly dry and the green melding into the surrounds, and with the hole position being stuck behind the mound on the right. Perhaps not the best example.
Usually, even where everything isn't laid out in front of you there is some indication of where a hole goes, whether its the way the ground falls, the shape of the fairway, the bunkering (eg Simpson's lighthouses) or the simple expedient of a marker post. Usually there's something that helps you intuitively work it out. In the absence of those signs, either by design or neglect, has the architect done a bad job ?

ps. anyone notice that when they play a course for the first time, they play better, as they engage the brain more ?
