A '''Skewed XY-Wing''' is an [[XY-Wing]] where at least the [[pivot]] and one [[pincer]] are on the same [[diagonal]].

=== Example 1 ===

In the this example, the pivot and one pincer are on the same diagonal.

=== Example 2 ===

In this example, the pivot and one pincer are on the same diagonal and the pattern [[eliminate]]s 2 [[candidate]]s.

=== Example 3 ===

In this example, one of the pincers is present in both diagonals, one connected to the pivot, one to the target.

=== Counter Example 1 ===

In this example the picture looks almost perfect, with both pincers on a diagonal, but the pivot is not on a diagonal. This is a regular [[XY-Wing]] with one of the diagonals assisting in the elimination.

=== Counter Example 2 ===

In this example, one of the diagonals is used to target a [[candidate]] to [[eliminate]], but this is no skewed XY-Wing, not even a regular [[XY-Wing]]. Only one of the pincers is involved in the elimination.
