Your statement doesn't make any sense so I'll take this as a teaching moment. 

 

First lesson:

K=King, Q=Queen, R=Rook, N=Knight, B=Bishop, P=Pawn

How you determined the knight is on e7 is beyond me.

 

Second lesson:

ALL CAPS STATEMENTS ARE USUALLY MADE IN AN ATTEMPT TO INSULT. 

I wouldn't suggest doing this since you are just provoking me/others to call out your stupidity.

 

Third lesson:

My line: 1. Rf8 Ke7 2. Nf6+ Kxf8 3. Rf7# is in algebraic notation, a good thing to learn via wikipedia, and translates to this:

White moves the rook to the f8 square.

Black moves the king to the e7 square.

White moves the knight to f6 resulting in a discovered check, a good tactic to become familiar with, because the knight moves allowing the rook on the a7 square to attack the king which results in check.

Black captures white's rook on f8. There are other moves but checkmate follows regardless.

White moves the rook on a7 to f7 resulting in checkmate. I'll let you try to figure that one out.

 

Bonus question:

Mine is indeed a correct variation but, just for fun, what is your "solution"?

The glorious game of knights and queens! Far too complex for any modern engine to understand.  It is very close to an equal position but Stockfish gives black +28 or so out of the opening, and then it starts going haywire in the middlegame and has no clue what is going on.

My CPU fan started whirring like it was at 50% (Kinda hard for me to achieve), and I was wondering what happened/what would happen. Then it stopped and I was sad.

I don't think any modern engine will be able to solve knights and queens for a long time,  They would need different algorithms to understand the dynamics of 7 queens and 7 knights trapped behind layers of pawns.  But maybe AlphaZero could be programmed to learn it pretty fast!

@pmi It is a chess variant! It is an improvement of Horde or Dunsanys Chess.  And hopefully it keeps growing in popularity It contains lots of very deep strategy and plans for both sides.  This teaches us a lot about space, piece activity, controlling the center, prophylaxis, weak squares, and there are many many exciting tactics including multiple queen sacrifices and zugzwang for both sides!  And the best part is, no engine can solve it, so humans can actually beat engines at it!  It is a position that is very close to equal, but white must be safer and play slow and patient, black probes and pries, and waits for white to overextend or play too much on one side of the board and then black tries to organize sacrifices to penetrate the back ranks!
