No.852 by Igor Kochulov – Neutral duplex, determined by Back-to-Back condition. (JV)
Definition:
Back-To-Back: When pieces of opposite colors stand back-to-back with each other on the same file (white piece is on the top of black!), they exchange their roles. A pawn on the first rank cannot move. Any piece can make an en passant capture when it has got a role of Pawn by Back-To-Back.

I like how 1…Sg8 must be played before 2.Kf7. Which is better – Duplex, or (b) Face-To-Face?
