this proposed solution is inconsistent, does not lead to mate in two moves. Looking at another board found a solution consistent

A solution would be 1. Rc3 rc4, 2.Qb3 # or 1. Rc3 b3, 2. QB3 # or 1. Rc3 f7, 2. QB3 #
Presented as the solution, not all of them are wrong. I wish the author verify some of their solutions, because there is, in some, the ability to output to the check, thus making failure a solution to the problem.

Instead of 1... Rc4, black move was,1... Qxg8, how do you mate then in two?

Amazing puzzle
It's ultra hard and ultra beautiful, to find that first move... geez, took me an eternity. Specially cause there are so many moves after it, and depending on black's move there's a differente mate for each haha. And to millerdias_chess, your proposed solution fails miserably because clearly if you check with the bishop by moving the rook at first black will take the bishop with the queen. That's actually the HEART of the puzzle, to render that move useless.

True, I did not realize this when I was analyzing my solutions. I apologize for the wrong solution, that is how we learn, from our mistakes. But, I think the author should also look at their.

Nice Puzzle
Really liked this one, with the two main mating threats: moving the rook to block or cause a double check, and the knight to b4 both not quite good enough, until the queen lends a hand!
Thanks for posting it!

mbeatini,
After Nc1+ bxc1

1. Nc1+ bxc1 still gets black mated on move 2 (through 2. Rc2#) but black plays 1. ... dxc1=Q/R/B/N

Hardest 2 move checkmate ever
I tried for the longest time to solve this by first checking the black queen. I was about to give up until I started looking for the most unlikely solution. Putting the white queen next to the black queen sure seemed unlikely, yet that was the only way to create an unstoppable checkmate. A brilliant puzzle.
