That's not a matecheck! The Black King is still free for c7. He can easily survive.
A very good puzzle.

game is not mate. c7 step is remained?
king has escape on c7, but after rook b7 and king c8 is mate by queen a8!
It doesn't go through the end, because there are 2 possible continuations to mate the black king (Rb7 and Qb7). The puzzle always only allows 1 move.
Qb7 is a disastrous move because the black king can move toward the middle of the board.
Rb7 leaves mate in 1, but it could be Qa8 or Qc6 so there's no unique solution. The 6th move (Rb7) is unique in the continuation to mate in 7, but the 7th move is not.
King can escape by 5. ... Kc7, then black is in strong position to finish game
Nope. Rb7 is the 6th move, forcing Kc8. Then there are two moves for immediate checkmate: Qc6 or Qa8.
