meh first 1st!@#@!

I wanna be first!

Not first, but cool.

NrG:

If the king "agrees" in being extracted, then follows the check with the white queen in b5. The black king will have three choices: 1) Kc8,to get immediately mated by the white rook (Rb8); 2) Kd6,  to get immediately mated by the white queen coming to d5 (Qd5); 3) Ke6, trying to escape along a corridor between its own black pawns and the "forbidden rank" swept by the white queen. Bringing the white knights to the fourth rank, first with Nf4+ and then Ne4#, you'll complete the job. Knight checks restrict the choices of the defense to capture or flight, since interposing a piece doesn't work. Knight checks, then, restrict changes in the position, during the chase to the king. I hope I may be right and may help you.

Good day; bonne journée.

Continuous check
