White to move. How should white proceed?
Source: ChessToday.net
This seems to do it
1. Qc7+ Nxc7
2. Nb6+ axb6
3. Rd8 mate
Looks like:
1. Qc7 Nc7
2. Nb6 ab
3. Rd8#
if:
2. Kb8
3. Rd8 with mate next
jk
Nice,Qc7 and Nb6 and Rd8 mate
After the previous one, which i completely missed, this is easy enough for me! 🙂
1. Qc7+ .. Nxc7 (forced)
2. Nb6+ .. Kb8 (.. axb6 3. Rd8#)
3. Rd8+ .. Qc8
4. Rxc8#
As white, you would really love to open that d-file to threaten Rd8 at some point. There are two problems- black’s knight covers d8 at the moment (a queen sacrifice for the knight might clear it), and clearing the white knight out of the way immediately with playing Nb6 actually gives the black king a hiding place on c7. This is what I initially thought might work, but it doesn’t:
1. Nb6? ab6
2. Qe6 Qe6
3. Rd8 Kc7 and it is over for white. The particular idea is wrong, but the sacrifices of the knight and the queen are the right way to think, but the queen sacrifice needs to be done another way to close the c7 square at the same time. After thinking about it for a couple of minutes, it hit me- make black block the c7 square:
1. Qc7!! Nc7
2. Nb6 Kb8 (ab6 3.Rd8#)
3. Rd8 Qc8
4. Rc8#
1. Qc7+ Nxc7
2. Nb6 Kb8 (or axb)
3. Rd8#
A double sac! Qc7 followed by Nb6 sets up Rd8 mate or Rd8 and RxQ mate
Have to rush off. No time to look closely at this, but maybe don’t need to:
1. Qc7+ Nx7
2. Nb6+ axb6
3. Rd8#
or 2. … Kb8
3. Rd8+ Qc8
4. Rxc8#
1.Qc7+! Nxc7 2.Nb6+! Kb8 (2…axb6 3.Rd8#) 3.Rd8+ Qc8 4.Rxc8# (or 4.Nd7#)
Qc7+ Nxc7 Nb6+ axb6 (or Kb8 Rd8+) Rd8 mate
1.Qc7+ NxQ
2.Nb6+ PxN
3.Rd8++
That is easy
1. Qc7+! Nxc7
2. Nb6+! axb6
3. Rd8#
1.Qc7+ Nxc7
2.Nb6+ Qxb6
3.Rd8#

The checkmate reminds me of Reti-Tartakower game, Vienna, 1910:
1. e4 c6
2. d4 d5
3. Nc3 dxe4
4. Nxe4 Nf6
5. Qd3 e5
6. dxe5 Qa5+
7. Bd2 Qxe5
8. O-O-O Nxe4
9. Qd8+ Kxd8
10. Bg5+ Kc7
11. Bd8#
Back in 1958, I tried to win a free one-year subscription to I.A.Horowitz’s “Chess Review” by being one of the 1st persons to send in the correct mate starting with 9. Qd8+. I sent in the correct solution, but the postmark on my letter was not early enough to beat out the competition. I still have a bound copy of all the issues from 1958, the year that Bobby Fischer first won the U.S. Championship.
Hi Susan Polgar,
Nice puzzle.
“Qc7” perfect fit.
