Not anything.

Yeah, this one should have gone a bit longer, I think.

But the end of the problem doesn't prove anything.

what about 1 Re5

This wins the queen and checkmate should be simple with that advantage.

Re5 looses both the queen and the rook. 1.Re5 Nxb3 2.Rxc5 Nxc5.

relax hehehehe

this is after you solve the problem and it says problem solved mind you.

1.re6+ kg5 2.qg7+ kf4 3.qh6+ kg4 4.rg6++

or

1.re6+ kh5 2.qf7+ kg4 and it's a matter of removing pawns from g7 and h6

ok, check "view analysis source" ;)

ok

After not reviewing the analysis and source, I conclude this to be checkmate in a few moves.  I could be wrong, but I'm definitely lazy!

party in the USA

This is a forced mate in 6. But after Re6+ if the king moves to h5 there are two possible forced mates so the puzzle must stop where it does. If the king moves to g5  then the end is quicker. Qxg7+..Kf4, Qg3#

Problem ends once multiple winning lines emerge, it's pretty clear this will force mate.  The real value of this puzzle is using double check to keep the queen on the board while making an attack.

Why not to take a pawn Rh6+ or attack a queen Rc6? Might as well instead of running after the king through the maze of pawns.

* I guess a double check is necessary, due to the attack on the white queen...
