XY-Wing
Consider both candidates of a pivot cell and find eliminations valid whichever of its two wings contains their shared digit.
All candidates have been entered in the empty cells.
Cell A is 1 or 2.
If cell A is 1, cell C is 3. If cell A is 2, cell B is 3.
In every case, at least one of cell B and cell C contains 3. Candidate digit 3 marked × conflicts with 3 in any of these cells and can be removed.
