Medium sized study. Checkmate. Various tries. Stalemate avoidance. Refusal to capture undefended piece. Silent move (5.Bd4!). Battery. Discovered check. All the pieces move. In the starting position: Qd4 Ba1 and in the final position: Qa1 Bd4 (the White Queen and the Bishop change reciprocally place).
