Bob, this is obviously only my way of playing but I almost never use the chip and certainly not from rough. Equally not to a green that slopes away from you like that one does.
I'd have gone with my 64 wedge and played a pitch with full back spin. Chances are the ball would still have rolled well past the hole but it should stop quicker than a chip shot.
The back pin on that hole has always played the wrong distance, play a few yards less and put up with sometimes having a long but uphill putt. A birdie putt from 20 feet below the hole is better than a par one from 30 below.
Don't let the tough courses get to you, the satisfaction of a good round is all the greater when everything comes together.
I'll try to catch you for a game there some time, I'm no expert but may be able to give you some tips.
