Happy Thanksgiving! From @mvmac and I, we'd like to thank all of you for being such awesome members. We have TST because we like golf and golfers, so we wish you and yours the very best today. Thank you!
I feel the more important idea from the video is not so much the square setup but the idea of weakening the right hand grip to cup the wrists and maintain the bounce throughout the backswing instead of the takeaway uses in full swing mechanics.
