See attach-block for the fundamental shape here.
A first interesting point about this joseki concerns . Can White omit this play, in order to leave a weakness at the 3-3 point in the corner?

That idea is really in the realm of handicap go: playing the atari is undoubtedly the honte. There is an example from a quickplay game Cho Chikun-Kato Masao 1990-09-09, as here. After Black made strong shape with , and White invaded at once with , making miai of a and b.
In general this would be considered a thin way for White to play.
