How do you play an open G chord?

I often mute the A string as well, and generally play the D on the B string. Dammit, I now realize that it's probably subconsciously muting the major 3rd, since that bitch is 16 cents sharp. I've spent the whole afternoon watching videos and reading on intonation; this isn't a new problem and people have approached it in many different ways.

Unless I'm reading you wrong, it's just the nature of having straight frets on the fretboard. Your chords ring out in tune only if you use a true temperament fretted guitar. That fretting also assuming you will tune it to one tuning only. Changing the tuning on a true temperament guitar would in theory required refretting again for that tuning, which is silly
