Jim,
I practice every day. Some days, I just pretend to hit chips, using the chip/pitch without balls in a bunker with a line drawn the length of the bunker for a half hour or so, then follow it up with real chips in the bunker. This is to monitor my left wrist and where the divot begins and ends.
I will do the same drill with pitch shots in a bunker.
I putt through a 3" gate (100 at a time) from six feet, keeping track of how many go through the gate. Then I follow it up putting over a quarter from 5 feet trying to roll each ball over the quarter.
I set up with a "T", just in front of my feet and practice half shots, monitoring my position at the top, my alignment and my divot (I need a lot of work of that one). I move to punch shots doing the same thing, and finally full swing.
Sometimes, I just practice full swings in a fairway bunker to force myself to make better contact- a compressed shot from a fairway bunker is really the result I'm looking for IN THE FAIRWAY! All of these are done towards a target.
I honestly have no idea what clubface control means and don't know how to practice it. I know what Plane line control is, but have no clue how to practice it. Any suggestions for each?
