Readers of Prime Obsession who were excited by my very brief account of Chebyshev biases in Chapter 8.iv, please note that the Jan. ‘06 issue of American Mathematical Monthly has a much longer account of the subject, covering the Riemann Hypothesis, too. The article is titled “Prime Number Races.” For reasons unknown to me, the authors use the French spelling of Chebyshev’s name. (But that’s nothing: This guy found 33 different ways to transcribe “Chebyshev” into the Latin alphabet.)
