B-N3 B-B1 15. N-B5 N-B4 16. N/3-Q4. The difficulty with this sequence is that on Black's 14th move, the Bishop cannot go back to its original square because there is a Rook there; also White's 15th move would require two hops of either Knight. So we need to insert a Black Rook move and a White Knight move to make the game-score work. There is more than one way to achieve this, but I have chosen the most likely move order - DMcA.} Re8 13.
