Don't think of accelerating the club, think of swinging all the way to a full finish. That will accomplish your prior teachers goal and it is easier to do without a lot of thought. I've noticed that my play has deteriorated - I am starting to slice and chunk the ball. I've noticed my grips feeling kind of slick. Please give me advice on the necessity of regripping.
Many players regrip once every few months .
I would suggest at least once a year, even if you don't play much because grips oxidize and dry out. Many tour players have played steel primarily for a long time. Most players need the extra help generating extra clubhead speed which Tiger does not. The keys are solidness of contact and clubhead speed. Thanks to Kim Brown, PGA Master Professional for answering these questions.
