I think you meant 278 XY Wing, not 273 - but why are you posting solutions that other people already posted days ago? I don't get it?

Oh! Thanks for clarifying that Mogulmeister. I didn't realize that he probably didn't see Zero's solutions because they were posted as white text on a white background! Sorry about that glesco! If you position your mouse at the top left-hand corner of the quote box, hold down the left-click, and then drag the mouse over the quote box, you will see the solutions!
