Still a mate in 4.
1... Kg8 2. Qxe7 Rf7 3. Qxf7+ Kh8 4. Qg7#

the rook can deliver checkmate

Keep it up, good problem.

if he had done that, white's rook would have taken his rook and it would be checkmate

it was easy

i got it after a few tries. good puzzle!

why didnt the king move to g8??

I thought there was a mate in four, but I miscalculated. Good puzzle!

White would take rook and it'll be mate.

ok

Because then you would move the rook to take the black rook and it would be check mate

this puzzle is not that much!

that´s right!

nice one indeed.

Nice puzzle

Qe6 in second move is also checkmate, except one more move..

nice

I think it will be a check mate in one
