watch his other clips,
he probably knows more chords than you.

btw, if you would play very sofisticated chords on arranger kyboard, some of them wouldn't be recognized by "auto-accompaniment" technology.

Why, thank you Vadim. I await his instruction with bated breath. Perhaps he knows a suspended chord too... I can't wait to see what appendage he does the drum parts with!

Me I only go as far as the demented, and demolished extensions. No point learning all those 'sofisticated' chords, if my arranger can't figure them out...
