Title: Submitted a request for a new warm up exercise

The exercise pits two players together in a grandmaster-style game of chess. Based on the ELO rating system for ranking chess players. Absolutely welcoming to comments and critiques on the difficultly level, readme wording, rspec phrasing, etc.
