Once you have completed the Tiger Challenge, have Tiger's clubs, and have power raised to at least 102 to 103, go to Stroke Play, Copperhead Canyon, black tees, and play hole 18. Aim the shot with a driver across the canyon onto the green. Hit it and you will have a putt for a Double Eagle. Note: Try putting Mulligans on. Also, if you are about to end up short put in a lot of top spin.
