There are sites that show the chords but no tabs.....how are you suppose to improve on your guitar knowledge if you dont want to know the chords?That is a very bad habit that is a "no no" to become a guitar player.
Find out about chromatic intervals to understand more about chord structure....meaning what makes a major, minor, dominant or 7th note.It will really help you on your playing plus once you master it there's no need to rely on those damn chord books...
