I believe Rd7+ will do the trick
Rd7+
Rd7+ is probaly the move.
Rd7+ Bxd7
Qf6+ Ke8 [Kg8 Qg6 mate]
Re1 mate
Rd7+ Kf1
Rf6+ Ke8 [Kg8 Qe6++]
Qxe6++
Rd7 Kg6
Qe4+ Bf5
Qxf5+ Kh6
Qxf6+ Kh5
Rf5++

I think, this is right way to chekmate in 7.
1.Rd7+ Bxd7 2.Qxf6+ Ke8 [2…Kg8 3.Qf7#] 3.Re1+ Be6 4.Rxe6+ Kd7 5.Re7+ Kd8 [5…Kc8 6.Qxh8#] 6.Rh7+ Ke8 7.Qxh8#
1.Rd7+ Kg6 2.Qe4+ Kh5 3.Rf5+ Bxf5 (3…Kh6 4.Qxh4+ Kg6 5.Qxf6#; 3…Kg6 4.Qg4+ Kh6 5.Rh5#) 4.Qxf5+ Kh6 5.Qxf6+ Kh5 6.Rd5+ Qe5 7.Rxe5#
Rd7+ Bxd7
Qf6+ Ke8
Re1 Qe5
Rxe5+ Be6
Rxe6+ Kd7
Re7 Kd8
Rh7 Kc8
Qh8++

I think you might be using a new graphic for the board. On my computer, there is very little contrast between the dark squares of this board and the black pieces.
All of the other boards that you use for your puzzles are fine, as I recall, but this one doesn’t really work. Thought you might like to know.
By the way, I really appreciate your puzzles.
rq5r/5k2/2Q1bp2/p7/1p5p/1P5P/2P3P1/3R1R1K w – – 0 1
hard to see the dark pawns on the dark background.
Sorry this is NOT Mate
Rd7+ Bxd7
Qf6+ Ke8 [Kg8 Qg6 mate]
Re1 mate
Sorry this is not mate. Black is still alive but in deep trouble.
I think if the dark squares were not so very dark then it would be easier to see. Usually the dark squares are only “grey” scale.
the only way for mate in 7 is the following one (best defense from black):
Rd7+ Kg6
Qe4+ Kh5
Rf5+ Bxf5
Qxf5+ Kh6
Qxf6+ Kh5
Rd5+ Qe5+
Rxe5#
all other black moves lead to mate in less than seven moves
@mtaurus:
1.Rd7+ Bxd7 2.Qxf6+ Ke8
would lead to mate in 5:
3. Qxh8+ Ke7
4. Qf6+ Ke8
5. Qf8#
your second idea is the right one!
IMO the best way is:
1.Rd7+! Bd7
2.Qf6+ Ke8
3.Re1+ Be6
4.Re6+ Kd7
5.Re7+ Kd8
6.Rh7+ u
7.Qh8#
“Sorry this is not mate. Black is still alive but in deep trouble.”
Yes, it takes a few more moves to mate in this line, e.g.
… Be6
Rxe6+ Kd7
Qe7+ Kc8
Rc6+ Qc7
Qxc7#
… Qe5 delays the mate for one more move, i.e. this is no longer a forced mate in 7. But Qxh8+ instead of Re1+ mates in just 5:
Qxh8+ Ke7 (only move)
Qf6+ Ke8 (only move)
Qf8#
hey, QM1 Todd R. Forbes (Ret), look the post above yours, the black move 1…. Bxd7 leads to a mate in five!
“hey, QM1 Todd R. Forbes (Ret), look the post above yours, the black move 1…. Bxd7 leads to a mate in five!”
Okay, I agree…how about this:
1.Rd7+! Kg6
2.Qe4+ Kh5
3.Rf6 Qh2+
4.Kh2 Rag8
5.Rh7+! Rh7
6.Qh7+ Kg5
7.Qh6#
“Okay, I agree…how about this:”
Yes, it’s another solution. I think white has some possible moves for his third to get the mate.
no!!the sulution is rd7+ kd7 QF6 ke8[kg8 of7++]re1+ be6 re6 kd7 or c7 oe7+ kc8 rc6+ qc7 qc7+++
Rd7+ Kg6
Qe4+ Kh5
Rf5+ Bxf5
Qxf5+ Kh6
Qxf6+ Kh5
Rd5+ Qe5+
