Maybe I'll go back to Warcraft. Nnnoooooooooo!
Do you have a link to that Fischer/Spassky book you mentioned, or at least the author and version? There are a bunch. Most are by Gligoric Svetozar, but not all. Also, I'm not sure which ones are annotated and by whom. Also, can you point me to any Fischer (or other GM or Master) games showing the thematic opening and/or defense you have been using? Thanks.
