They can kill Yahoo as the #2 search engine by leaving them unable to do anything, halfway between being bought out and with employees leaving in droves before they are fired and as Yahoo is floundering take there #2 spot. Then MS could take pity on Yahoo and buy them for real, breaking them up and selling off any pieces they don't want.
