As you progress in yousician, some chords appear to be picked, rather than strummed up or down, as indicated by the lack of up or down arrows.

However, it is unclear how these chords are meant to be played - if picked, how do we do so with 6 strings ?

Further to this, there are some chords that don't make any sense at all - seen for example, in Radiohead "the bends" full chords version - which is totally confusing.

It would be great to see some video tutorials demonstrating these techniques. Thanks.
