The only way to annihilate the bR is either by pinning it or by passive annihilation under bP. As the annihilation must occur in the forward play, white must first lure bK in the corner. This objective can be achieved through a sequence of consecutive preparatory maneuvers: The unpromotion of wS. This has a triple purpose: lures bR in a position where it can solely oscillate between g7 and g8, creates by suicide the second light square wB and takes the control of g8 for the final stalemate. Getting wBa8 near the bK. The staircase-like movement Ba8-b7-c8-d7-e8-f7 is needed in order to be able to finally place wB to c4, forcing bK to make one step forward the most distant corner (h8). Draw pendulum. After the wB gets on d5, both Ks oscillate: wK between f1 and g1, bK between f4 and f5. Finally the bK is forced to release again his central position and forced to play on g5. King harassment by Bishops. wBf3 forces the bK to get from g5 to g7, wBd5 forces the bK in the corner and the bR on g7. Now the final blow is possible with two simple Knight jumps, capturing in the forward play the bPg3 and putting it back on g7! (Author)
