Ryan Elbwood is a developer and designer of over 270 games. Among them are several games with tactical and/or strategic character. One of his games has nearly 4,000 variants and holds the absolute world record in its segment.
Elbwood also wrote under the pseudonym "Chris Wolker" the ens-thesis in 2008.
The ens-thesis is a cosmological treatise and counter-thesis to the Big Bang Theory. Elbwood recognized long before the first images of the James Webb Space Telescope that the cosmos is of being and not of arising nature and that the Big Bang never happened. Many of his predictions have since been confirmed by the JWST.

Elbwood has been interested in the alien/UFO phenomenon since his earliest childhood and has been following the topic very thoroughly ever since.
In this book, he sets up a hypothesis as a sharp-thinking strategist and tactician, which he himself calls the checkmate hypothesis.
He builds his hypothesis in a scientifically professional and yet unique way. He introduces all the people from the scene who gave him a lot of knowledge. Then he presents many important UFO sighting and UFO crash cases. Among them his own UFO double sighting from 1993. After that he asks many important questions and answers them as far as possible. In an almost criminalistic way he then constructs a convincing case whose evidence and facts are irrefutable.
Amazingly, in the end, the foundation of the hypothesis also has a high stability without aliens and UFOs.
At the end, Elbwood surprises with an exciting, emotional and humorous experience in a crop circle, which will surely remain in the memory of all readers.
Throughout the book there are first-class pictures to be found, which make reading almost a cinema experience, because the pictures were scenically optimally adapted and underline the respective mood.
