In my experience of working with club players, this is a shot that causes a lot of problems. You are almost certain to need it in every round you play so take some time and get comfortable chipping from a down slope. Like most shots, It starts with understanding your viable options.
The Chip and Run is comfortably the easiest shot to play around the green. It requires a very short swing so less co-ordination required for beginners. It is also very forgiving on mis-strikes with thinned shots often finishing nest to the hole.
To develop the elusive 'feel' in the short game, we need to be able to see a trajectory and then make it happen in one 'embodied' process of action and perception. This level of skill ownership comes from hours of varied practise around a green where you experiment with all options of set up and stroke.
