I made an assumption that Google didn't like showing multiple results with the same title, as mentioned a few posts up, but after further review I retract that. If two sites are all about the exact titles they are showing Google will show more than one.
My competitor who jumped the rankings with the words All and Every must be deemed all about those words since they are on every page and there is very little other content on them. I'd bet my bottom dollar that his/her GWT account shows those words extremely prominently in importance.
They aren't important to my site so I tried something else. I picked a word Google has associated to my site rather highly and appended it to my title on a few test pages. Voila - I dominate the competitors variance with mine and rank ahead of him/her on these test pages.
While my word isn't as yummy to visitors as "every" it is getting a CTR roughly 5% higher than without the word, in part due to the rank increase. That GWT list of important keywords is golden.
If you are inclined to write an article about widget guides but have never used the word guides on your site you're just not going to gain any benefit with that word in your title, at least until you prove your site is about guides too. Working within your Google-defined important keywords seems to provide best results in the short term, stretching the list is a good idea for the long term.
My site has 2 keywords that are 75% more important than any other keyword and I suspect that makes it hard to rank for things not related to them. More testing...
