Mashup sport: chessboxing. "The basic idea in chessboxing is to combine the no.1 thinking sport and the no.1 fighting sport into a hybrid that demands the most of its competitors - both mentally and physically. In a chessboxing fight two opponents play alternating rounds of chess and boxing. The contest starts with a round of chess, followed by a boxing round, followed by another round of chess and so on."
