© Jonathan Whitcomb 2011 Two critical key squares are d8 and f7. The white knight seems to almost have a forking opportunity; what prevents a knight fork at f7? Immediately capturing the black pawn at f7 fails because of a recapture with the black queen (with a potential threat of capturing the white pawn at f2). But it is black’s queen and rook that prevent that knight fork. Does anything sound familiar with that? Those are the two pieces preventing a back- mate at d8: two critical key squares. Have you found the solution? Use both of the keys to unlock this chess combination. Whitcomb 2004 Ropen Expedition Just a few weeks before the Woetzel-Guessman ropen expedition of 2004, Jonathan Whitcomb explored the same island (Umboi, called “Siasi” in Papua New Guinea). Most of these kinds of expeditions involve two or more Americans, but Whitcomb took a native interpreter with him to Umboi Island: Luke Kenda. Two weeks on Umboi resulted in many interviews with natives who had seen the ropen light or the features of the giant flying creature. One eyewitness, Gideon Koro, and his six friends, saw the ropen close enough to distinguish details: a mouth “like a crocodile,” a tail “seven meters” long, and “no feathers.” Although universal pterosaur extinction (of all species) is often taken for granted in Western countries, that is an assumption, not a scientific fact. 2nd Key to the Combination Appreciate clear thinking; it’s worth it.
