Nothing new under the sun

Hi Bonar fans,
ever heard of "THE GOLFING MACHINE" book by Homer Kelley?
this "magic move" Bonar "discovered" actually was already known in 1969 and
well described in that book. But it is only one of the zillion ways to swing a golf club.
Ask Bonar how you can hit a fade with that kind of hands action!
That magic move is called "dual horizontal hinge" in The golfing Machine and it is
only one of the three possible hinges of the wrists at impact.
Cheers
