You are cordially invited to match wits with some of the best minds in IBM Research.

Does that sound like you? Good. Forge ahead and ponder this month's problem.
We'll post a new one every month, and allow a month for you to submit solutions
(we may even publish submitted answers, especially if they're correct).
