  <p>Let's gloss over the details (<code>9.Rxh7</code> is a bluff, <code>13...Be4</code> is a bit stronger, any analysis would be OT here but feel free to put it into comments) and just look at the motif: <code>Bc1-h6-f8-h6-c1</code> (the latter mandatory to block the 1st rank against <code>Nb4 Na3 Rh1+</code>. I know a study where White returns six (?!) pieces to homebase, but here the bishop even starts from it. Also I recall some game moves (Alekhine?) <code>Q-c1-g5-c1</code> or the like, but that's not homebase (and it was a &quot;positional combination&quot; anyway). Thus:</p>
  <p>Can you show me a combination where the player gets advantage from developing a piece and later returning it to the homebase square? (Patterned search should be possible. <code>Ra1-b1-a1</code> for an attack on the queenside counts, for example, even if it isn't that spectacular.) Bonus for longer running around and no inbetweens (like my <code>12.Rxf8</code>).</p>
