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