XYZ-Wing
The three cells {0}, {1} and {2}
form an XYZ-Wing pattern on the value {3}.
Regardless of the correct value of the cell {0}
({3}, {4} or {5}),
either the cell {0}
contains the value {3},
or one of the two cells {1} or {2}
will have the value {3} as its only remaining potential value.
It follows that one of the three cells
{0}, {1} or {2}
must contain the value {3}.
Other occurrences of the value {3} can therefore be removed
from any cells sharing a (row-or-col) and box with all three cells.
