				Same cells and elimination as Ted, but a different interpretation.

				| Too abstruse for me - but I think there was a w-wing for <28> that removes the <8> from R2C4.  It don't get me nowhere though. |

				A three-step xy-chain eliminates the 8 in R2C5 and solves the puzzle.
 
Love those xy-chains!
