Much more challenging is the copyright issue. You obviously can't copyright a hand, or even a particular analysis of a hand. If Card Player publishes, "the chip leader picked a bad time to semi-bluff with his gutshot since his shortstacked opponent appears to be steaming" and you post the exact same idea with slightly different words, I seriously doubt they have an action. If all the problems in the book were eventually posted here, there would be a fascinating case, but I'm not convinced the book publishers would win, unless substantial portions were posted verbatim, or with mild semantic variations. Think of an algebra textbook, with a series of equations and concepts in logical order. Can't copyright the equations or the concepts or the logical order, so the offending version must be extremely close to be actionable.
