Knowing The Fretboard Through Chords
In reading through "The Guitar Player Book, 3rd Edition" I found a fantastic interview with Pat Martino. Let me warn you, this isn't a lesson to teach you about chords or new chords; it's a different and interesting way to look at chords and how they can help you learn the fretboard. You should know chord types and about making chord formulas for this. But I'll make a long story short, so let's get to the good stuff.
Pat talks about how it's easier to draw dominant 7th chords from a diminshed chord, rather than a major chord. If you learn diminished chords, you can take them apart and build four dom7 chords. This allows you to learn 12 7th chords within three frets, or within each position.
