A German publication on the subject "problem chess" undergoing a third revised edition may be nearly considered as a singularity! The attractive paperback is filled with 300 well-chosen tricky problems (1st ed. Munich 1980; 2nd ed. 1982; 3rd ed. 1985, 224 pp.) – time and again you will just like to pick up this small classic. Godehard Murkisch founded his own publishing house in 1999: Nightrider Unlimited.
