Hi Mac,
Yes, your point is taken. In my previous post I was referring more to Shazbot's suggested link which, to me, similarly explains the principles of "Locked Candidates" as you did. Your explanation certainly helps sdkNewbie to understand these same principles and to help solve this particular puzzle but I'm not sure if it helps solvers any better to identify this particular technique by themselves.
