AIC Type I / Sudoku Tutorial #34
An in-depth look at an AIC Type I, followed by a Tutorial on Chain Construction. This is a LONG one! It is 30 minutes to the Intermission, and then the Chain Construction Tutorial is 20 minutes long. So I recommend watching this Video in TWO Sessions. It is actually two Lessons in one. Hope you enjoy it, and find it helpful. :-)) Also includes a quick explanation of the concept of "Cannibalism" in Sudoku Chains.
