This is called bifurcation (which in its extreme form is basically just guessing), and even if you were a person that doesn't mind a method being somewhat distasteful as long as it produces results, the specific thought chain is unnecessarily long in both directions: You could just say: "if r3c6 is a 1, then both the bottom left squares are twos", and be done with it. | |
