Rule: When between clubs, take the longer club and grip down. Then make your normal swing.
Don’t try to hit the ball harder, because you don’t have to, and for sure don’t ease up, because that’s like hitting the shorter club.
One of the things that made me be a better golfer is that I don’t care where the ball goes after I hit it. If it goes here, or goes there, I just get to my ball and play the next shot, whatever it is. If you want to put your best swing on the ball, let a graceful swing flow through the ball, and leave it at that.
Consider this point well.
