Thanks - I've checked out some of your swings and you are right I have a similar tendency. I have seen many examples of good golfers with 'some head' movement. For example a degree of lateral movement on the backswing or head dropping in a vertical plane on the downswing. I would be relatively comfortable if I just did this - I'd be in good company
The reason that I titled the post 'three dimensions' is that I also spot this upper neck/check contraction which retracts the neck in and away from the position at address. I can see that movement in your swing too although not as pronounced as mine.
The last three days I've been spending quite a bit of time at the range just hitting wedge shots and trying to keep the head 'out' over the position at address - I'm using a wedge so that I am just hitting soft gentle shots and not trying to swing too hard.
I am coupling it with the drills I mentioned earlier with keeping my head against a door or wall and doing dummy practice swings without a club.
With the wedge work I've noticed a big improvement in the ball flight - it feels as if it's taking off 5 yards further to the right. It's a shame I can't seem to work out how to put a video link in here to show you my predicament.

I'll try it again but instead of making it a URL I'll just paste the text - it means if anyone wants to look they'll have to cut and paste. Apologies.
