As you all know chords can be played at different locations on the guitar. I have laid out for you A7b13 in 12 variations (of course there are some more possible variations).
A7b13 chord is built out of R-3-5-b7-b13(=>#5) (A-C#-E-G-F).
Special on this chord is that it has a perfect 5th and a sharp 5th at the same time.
Because of this it gets the name b13
