You two are arguing the toss. Augusta's 15th has a forced carry. Its up to the player to decide when he wants to make the carry, but that is true of all forced carries that aren't one-shotters.
The idea of a forced carry goes against the grain of what I consider the best designed holes, but for variety sake, one, maybe two is ok especially if there is plenty of room to err on the far side of the carry. Of course, it depends on how forced it is. For instance, I just played Edgbaston and there was an interesting hole which the player could play over water or out right. A stream bisected the fairway as well - this is the forced carry part. However, the player could choose to short cut the water and try to carry the stream as well or short cut the water and be short of the stream or just bail out right. What is cool is that the stream is not a hard carry for those who lay up, but quite hard for those trying to carry a the whole sheebang.
