Ardson Not So Hard Ardv2 118

Ardson Very Hard v.2 118 shows off the basic steps, but can’t quite dodge the consequences. A good Sudoku basic workout, and reminding us of the joys of basic solving.

Here is the basic trace, completing box marking with a naked quad.


The grid completes the checkpoint.









The column 6 marking completes a naked triple in r1, which restricts r1c8 enough for the naked pair 26 in the c8 marking, and clues NE9 and SE3, folding up Ardv2 118.

Next time, we move on to Ardson Very Hard v.2 158. That will be in two weeks, May 16, because of unforseen difficulties.
