XYZ-Wing
Consider a three-candidate pivot and its wings to find eliminations valid wherever their shared digit appears among the three cells.
All candidates have been entered in the empty cells.
Cell A is 1, 2, or 4.
If cell A is 1, cell B is 4. If cell A is 2, cell C is 4.
In every case, at least one of cell A, cell B and cell C contains 4. Candidate digit 4 marked × conflicts with 4 in any of these cells and can be removed.
