Is this chess study by Josef Kling correct ?

Can someone enlighten me here ?

EDIT: Klartext has posted a much more thorough solution below. That deals with every possible defense, mine deals only with whatever Stockfish plays.

I found a variation that does indeed force the checkmate while playing against Stockfish. It seems that the study is correct.

The numbers at the end of a variation mean: 'see move <number> in main line'. I have not finished all variations at the start, in order to keep the amount of variations low. I leave this as an exercise to you ;-) Sooner or later you will reach a position from the main line.

The general idea is:

* First drive the King towards a1, by reducing his possibilities with the queen. Thats not too difficult.

* Once the King is on a1, a tricky maneuver has to be found which chases him to a2 in a way which allows Qc1 afterwards. This is achieved with the key move 14.Qd4!

* From that on it is once again driving him towards the left border, by reducing his squares with the queen. This time the king c6 helps (And this is not possible earlier, because the black king can run away via e5).

* Finally the maneuver Qb5+ followed by Qb1 chases him towards the mating square.

Wow, incredible ! Thanks a lot !

@doom12384 didnt reload, so didnt see your study :-) Can you make it public? We can not see it.

@Klartext
Sorry about that. It should be visible now.

@doom12384 How would you continue if he plays 8...Kb2, with the idea to run away via e5?

And which better move could you play on move seven?

@Klartext
Well, having seen your study, it is clear that 8...Kb2 is met with 9. Qd1 Kc3 Qd5, closing the king into the corner. Better than 7. Qd2 is 7. Qc3.

I simply found a single solution against Stockfish, although I did not account for a lot of the possible defenses (since we assume that the white king cannot move).
