Unbearably "cute". Strobach attempts to explain everything as if it were a card game, which muddies his exposition, while patronizing his readers. If you don't understand how to use logic, pretending that true and false may just as well be substituted with black and white won't help. Or if it does help a few, it will baffle a few thousand. All that space he used up trying to be so fun and clever could have been filled with more examples and exercises.
