Today's Superior Sudoku 17, was relatively easy, solving with a x-wing.

Can we have Superior's that are abit more tricky with another technique used to solve the puzzle, like a swordfish or colouring with 2 numbers

(ie. Numbers A and B in 4 cells, and where 2 of these cells meet, A and B can be eliminated, leaving the cell with a single number)
