I also read "Ike's Bluff" which surprised me. When Ike was a young officer he had to give up poker because he was wiping out his friends' savings. Turns out he played such a close and effective hand of diplomatic poker against the Russians that even most Americans don't realize how smart he really was.
I also sold an article "Race in Hollywood" to New Myths magazine. It focuses on James Baldwin's essay "Devil Finds Work" and my own knowledge of science fiction.
