Yes, I believe that when most ppl compare the the 2hBh to a lefty Fh, they are referring to a classic OTS Fh with a neutral stance & weight shift (and not to a so-called "modern Fh" with a fully open stance). More important, the hips and upper body resemble Fh mechanics much more than a single-handed Bh does. The comparison to the lefty Fh pre-dates the popularity of the open stance, modern Fh.
Makes sense.
The reason why I don't like the LHF analogy on this forum is that I suspect many players here don't really know what the classic forehand is, and probably just assume forehand = "modern forehand".
What Agassi says and how it appears is a bit misleading. From his perspective, he feels that the right arm is pulling more at the start of the forward swing. Perhaps so. However, it does not look substantially different from players who pull with both arms at the start of the forward swing.
Here's what I think is unconventional about Agassi:
- the pronounced snap back of the rackethead when he starts his forward swing. Worded differently, he sticks out a ton of buttcap. This is caused by the next 4 points.
- his straight right arm
- his racket head is very far away from his body at the top of his backswing.
- his straight wrist; It doesn't bend on the racket drop like most players.
- the pronation of his right forearm at the racket drop. Because of his straight wrist, he
has to pronate on the drop.
- by the start of his forward swing, his right arm and racket are basically in the "power position" of the 1hbh.
- his tendency to raise his right shoulder through contact
- he sometimes lets go with his left hand soon after contact, like Borg. He seems to do this when he adds more spin, like for a cross-court angle. Though I'm not entirely sure how often other players do this, if at all.
To me, this all suggests a strong right side, at least for the majority of the forward swing.
About mid-way thru the forward swing prior to contact, the left arm takes on a more dominant role. I suspect that this is the same for Agassi (even tho' he words it a bit differently).
It
could be that Agassi is actively pushing with the left immediately before contact.
Or it could be that his left is swinging through passively and his right is taking the lead by supinating.
Or it could be that they are
both passive right before contact, and we are simply seeing inertia.
Right now, I don't see a way of telling which it is, although I suspect they are both passive before contact and that he basically flings his racket head at the ball (as in a "pull" forehand).
In any case, I think most of the effort being exerted takes place in the early part of of the stroke.
