Nicely explained - thanks

at about the 4 minute mark you talk about a "deadly Pattern" and I don't understand. If F5 is a 1 and G6 is a 1 which makes makes F6 a 2 and G5 a 2 this fits the rules at this point. If F5 is a 2 and G6 is a 2 which makes F6 a 1 and G5 a 1 it also fits the rules. I don't understand why you say G5 can't be a 1 or a 2 at this point!

Sudoku puzzles only have 1 solution. If the 1s and 2s were in those positions that he said they can’t be in the puzzle would have two solutions.

​@@LvLdGhost couldn't somebody accidentially or intentionally make one that had more than one solution?
