Judge's comment [Kostas Prentos]: "In order to allow Black’s castling, the wRh1 makes a 15-move round trip to b7 and back. Two more white pieces return home, covering the Rook’s trail. There are many familiar elements (compare with the pioneer P1000010, and also P1106927, both by Caillaud) but the economy and timing of this capture-free gem are impeccable."
