Do I have to putt over dead grass?
On the green? Maybe. Check with the course to see if you get free relief from the burnt-out area. If so, lift the ball and place it at the nearest point that provides complete relief—or the maximum available relief—so the grass is no longer on your line. That point cannot be in a hazard or closer to the hole and might be off the green. Otherwise, play it as it lies.
