when I open my stance for shorter irons & wedges (prefer to think of it as just stepping forward with my right foot since I usually keep my shoulders on a chosen target line) I just assumed that opened stance worked because it allowed the hips to clear faster / easier for the shorter radius swing(?). (Ball already at your side kind of thing).
Thank you, Phily & Martin, for the recent insights.
I like the description of "just stepping forward with my right foot" while keeping the shoulders on the target line.
Continuing the scholarly nature of this thread, I searched through the Stance and Posture Lesson in Hogan's book, but did not find mention of this principle. In strict academic terms, this discussion should perhaps take place during Lesson 5 - Summary and Review, because that is where I found the following passage.
Hogan mentions that there is "no conscious variation" in the way one swings the different clubs, but suggests that a change does indeed take place. Hogan notes that the shorter clubs have shorter swing arcs, occurring on more upright planes. With these shorter swing arcs the golfer has,
"…less time on your swing to get your left hip out of the way. That is why I make - and suggest you make - a mild modification when you are playing the clubs from six-iron down to wedge: GET THE LEFT HIP OUT OF THE WAY BEFORE YOU BEGIN TO PLAY YOUR STROKE. You do this by setting your right foot a bit nearer the ball at address, as the diagram below illustrates.
This has the effect of drawing the left foot back from the direct line and turning the left hip a bit to the left - opening the hip a shade, in other words. When you play the clubs from the six-iron down with your body in this position, you still feel like you're taking a full swing. Actually you're not. You have placed a further restriction on the length of your arc. You will sacrifice some distance as a result - the club cannot travel so fast on a shorter arc - but what you lose in distance you more than make up for in direction. When you're playing the short irons, accuracy, of course, is the primary consideration."
