X-Wing contributed by Lynne

The new strategy page on this site has now included a section on the X-Wing strategy.

I'd managed so far without using anything quite as complex looking as this. Is that experience just me or do my fellow puzzle solvers also find that they can cope without frying their brains trying to find these obscure patterns in puzzles?

X-Wing aid (re: X-Wing) contributed by Lynne

Yes they are useful, really.

Many of the challenging level of difficulty puzzles on this site require the use of X-Wing.

They crop a lot in the larger 16x16 sudoku grid puzzles too.

That's probably because there are so many more squares and the pattern of matching rows and columns required for the X-Wing are much more likely to occur.
