Whereas card game books tend to concentrate on Cutthroat Pitch, most of the e-mail I get is about Partnership Pitch, and this preference is reflected in the balance of information on this page. I have the impression that Cutthroat Pitch is more often played on the coasts, and usually for money. The various types of Partnership Pitch are most popular in the mid-west and are family or social games played to a score. There are many variations of pitch, mostly involving increasing the number of points from four to five, ten or more by introducing extra scoring trumps. Extraterrestrial, high energy gamma rays include the gamma ray background produced when cosmic rays (either high speed electrons or protons) collide with ordinary matter, producing pair-production gamma rays at 511 keV. Alternatively, bremsstrahlung are produced at energies of tens of MeV or more when cosmic ray electrons interact with nuclei of sufficiently high atomic number (see gamma ray image of the Moon at the beginning of this article, for illustration).
