Thor (The Mighty) Vol. 1 Annual 9

"The Great Game!"

After Don Blake saves the life of a young boy, Thor returns to Asgard to take part in some sport. But they are attacked, and Thor is injured. During his recovery, he sees witchfire and demons about Asgard, but no one else does. When he checks on Odin, he finds him playing chess with Dormammu, with Lord Chaos and Master Order being affected by their game. Thor is then manipulated into almost helping destroy everything by helping Odin win, by Umar. But with Sif and Jane Foster's help, he manages to stop himself, with the chess game ending as it should, in a balanced draw.

"The Godwar Gambit!"

"Shall Chaos Die?!"
