The golf journey has plenty of ups and downs, and swing changes or adjustments are always needed on the way...

So the latest adjustment of back swing is this: smoothly swing to 3/4 position (left hand parallel to ground, club upright and wrist hinged, to form L shape), from there, just turn/rotate upper body (shoulders) to finish back swing (stop when back is facing target) with straight extended arms/hinged hands passively following to the top. From there, initiate down swing with lower body - get the hip out of way first.

With this adjustment, driver performance was recovered: mostly straight or draw. This adjustment was initially for driver, and then later applied to other clubs. Hybrids and irons (except for PW)  feel great, with added length. But 5 woods would push to right and PW inconsistent (left and right), so need more practice at the range for these clubs...

Played a couple of great rounds in 70s using this swing adjustment: Majestic Springs (Oct. 20) green tee: 11 fairways, 12 GIR, 2 birdies. California white tee (Oct. 23): 10 fairways (12 on target line), 6 GIR (a couple bounced off green), 2 birdies (1 chip-in).
