Hi, everybody. I'm familiar with the meaning of this idiom, but I'm not that familiar with its use. Can this idiom be used in the past tense (as in Johnny played devil's advocate and made Susie realize her plan wasn't exactly brilliant) ? I have found some instances of its use with the future tense, as in: I'll play devil's advocate for a moment and warn against the flaws of this new method. But can you still use this idiom without for a moment (as in: Next summer, I'll play the devil's advocate and ask Mrs. Wright about the minor details of her campaign) ? Also, is there any difference between using play devil's advocate and play the devil's advocate ?
