A Skewed XY-Wing is a XY-Wing where at least the Pivot und one Pincer are on the same diagonal.

In the examples the pivot is pink, the pincers are orange and the cells where the value can be deleted green.

Example 1

In the first example both pincers are on different diagonals.

Example 2

In the second example one pincers is on a diagonal, the other pincer in the same line like the pivot.

Example 3

In the third example one pincers is on a diagonal, the other pincer in the same box like the pivot..

Example 4

In the fourth example we see how it degenerates if the pivot and both pincers are on the same diagonal. We have here a combination of Naked Triple and Pointing Pairs.

Example 5

This example doesn't shows a Skewed XY-Wing. There is no pincer that is on the same diagonal as the pivot.
