First photo really looks like pulling...everything is in line for pulling (forearm etc)...
Now look at this one:-
To get the right wrist this bent long after lowpoint...is that a result of the force on the clubhead from the sand...ie. delaying the clubhead as the hands move forward...or is there an element of right arm active thrust that gives this appearance...
The last photo is actualy reproduced on the cover of the book(novel/non-fiction) "The Match"...just read it...good fun...nice one for the fireside for Christmas!
