Chthonic, the irascible bridge-playing computer, is back. This time, he's attempting to teach humans a little about the game of bridge - not in order to turn them into competent players, as he recognizes that is impossible. But he thinks he may be able to get the reader to the point where his cell phone won't laugh at him behind his back every time he plays a card. Each chapter of this wickedly funny book highlights a different 'human bridge error', and points out why and how it should be avoided.
