Chess Puzzle I Composed

Here's a chess puzzle I composed. There are many good moves, but try to find best that leads to a mate in 8!

Try to rate it in difficulty, please.

Rf7 Bxf7.

The first move isn't check, so if you find the first move, I'll give you all the credit since there are many variations for the resulting checkmate.

Rc6 looks good, threatening Be5#.

Really though, Nxg5 looks fine.

Nxg5 isn't the best, but you have the right idea of moving the rook for a bishop mate. But which rook move is the best?

I meant from a practical point of view, game looks over after Nxg5.

As for the problem, can't get it yet.

This is a great and well thought puzzle!!

So you got the answer?

how bout start with Re7 followed by Be5# black can only delay

Yes...

yea that looks correct king can escape after Re7 f4 i think

Good job, s0030135.

Please post the difficulty out of 5.

For him, 0.

for me, checkmate difficulty:5

winning difficulty: negative over 9000
