    A game ended with 6.BxRc4# (mate). What were the previous moves?

    Assuming it is White that mates, Black must have made 5 moves.

    Play might go
    1. e4 a6
    2. Bxa6 Other move
    3. B move Ra4
    4. Some move Rc4
    But I can't see what Black can do with just 2 moves.

    Otherwise he requires 4 moves to move his rook to c4, 1 move to move his king onto the a2-g8 diagonal, and at least 1 pawn move in which case it is impossible.

    Therefore the Black king must be mated by discovered check (possibly using the White queen), but this seems equally problematic.
