Tiger's comment reminded me of advice I used to give my guitar students: If you are really having a hard time fingering a chord, try moving your elbow to a different place. Often the elbow would end up directly below the point of greatest finger pressure - but not always. At the time, I didn't really think about what was happening with the wrist. It always seemed to me that the wrist bent the way it had to bend. But I have always advocated the avoidance of using only barre chords in a piece (wherever feasible). Switching between them and open string chords gives your fingers and wrist a much needed moment of comparative relaxation. -- I learned this when playing rhythm guitar in the days of the old "garage bands" of high school.
