I just had my guitar instructor show me how he does the A chord with just his pointer finger His finger end flexes back enough he can bar the three strings with the one finger and still leave the the upper E ring. My finger doesn't do that but what I do for A is stack my fingers as 213 instead of 123. Gives me the room I need. Be creative
