White to move. How should white proceed?
- Rf5+ gxf5
- Bd5 Rad8
- Bc6 Rdf8?
(... Re3+ 3. Be3)
- Rxa7 Rd8?
(White either gets a rook or promotes a pawn.)
Question regarding annotation: how do you indicate, as in 2 and 3, that all moves for black are equally useless? Do you just choose one of many useless moves, and put a question mark beside it, as I did here?
What happens if the pawn rather than the bishop takes f5?
- Rf5+ Bxf5
- Bd1+ Bg4
