1. Qh5+ Kxe7 2. Rxg7+ Ke6 3. Qe2+ Kf5 4. Qg4+ Ke5 5. f4+ Ke4 6. f5+ Ke5 7. Qe2+
Kxf5 8. Rf1# 1-0
This one was pretty tough for me.
1. Qh5+ KxNe7
2. Rxg7+ Ke6
3. Qe2+ Kf5
4. Qg4+ Ke5
5. c4+ Ke4
6. f5+ Ke5
7. Qe2+
if 7…Kxf5 or 7…Kf4 then 8. Rf1#
did black already retreat the pieces to start a new game? i found a cool checkmate in 8:
1. Qh5+ Kxe7
2. Rxg7+ Ke6
3. Qe2+ Kf5
4. Qg4+ Ke5
5. f4+ Ke4
6. f5+ Ke5
7. Qe2+ Kf4/xf5
8. Rf1#
(2. … Rf7, 3. Qxf7#
1. … Ke6, 2. Rge1#)
greets, jan
Mate in 8 is probably something I am not able to find, I will concentrate on something that looks like a logical attempt to win:
1. Qh5+ Kxe7 (Ke6 Re1#)
2. Rxg7+ Ke6 (Rf7 Qxf7#)
3. Qh3+ best looking move.
a)
3. … Ke5
4. Qe3+ Kf5
5. Qf3+ with possibility to take Ra8.
b)
3. … f5 (looks better)
4. Qh6+ Ke5 (Rf6 Qe3#)
5. Re1+ Kd5
6. Qd2+ Kc6 and now it looks difficult, e. g.
7. Qh6+ Rf6!
I dont’t get further at this time.
Qh5+ Kxe7
Rxg7+ Ke6
Qe2+ Kf5
Qg4+ Ke5
f4+ Ke4
f5+ Ke3
Re1+ Kf2
Qe2#
Nice one.. took long to solve, we cant ignore pawn on a2, need to find way that will continuously chase black king and does not allow to rest !!
TWO Steps for “KO” :
1.Qh5+ Ke6
2.Rge1#
THREE Steps for “KO” :
1.Qh5+ Kxe7
2.Rxg7+ Ke6
3.Qe2#
– High skill from MR KO (Malaysian)
Not sure about 8 moves but Qh5 seems to lead to check mate pretty fast.

After toying with this puzzle for a while I couldn’t find mate in 8. However, I found mate in 14 if that is any compensation.
1.Qh5+ Kxe7
2.Rxg7+ Ke6
3.Qe2+ Kf5
4.Qf3+Ke5
5.Re7+Qxe7
6. Qd5+ Kf4
7. Rd4+Q e4
8.Rxe4+ Kf3
9. Re7+ Kxf2
10.Qd4+ Kg2
11.Re2+ Kh3
12. Re3+Kxh2
13.Qd2+Kg1
14.Re1#
1 Qh5+ Kxe7
2 Rxg7+
2 Re1+ Be6 leaves White nothing better than a perpetual after 3 Rxe6+ Kxe6, 4 Qe2+
2… Ke6
3 Qe2+
3 Qh3+ allows Black to escape with f5, as Black’s King or Queen can then get to f6 when needed. Again , that leaves White with no better than a perpetual.
3 … Kf5
4 Qg4+
There are other ways, but this is fastest.
4 … Ke5
5 f4+ Ke4
6 f5+ Ke3
Or 6 … Ke5, 7 Qe2+ Kxf5, 8 Rf1#
7 Re1+ Kf2
8 Qe2# or Qg3#
It took me a while to find this one. I ended up in the rabbit hole of trying to make 1.Rg7 work. The right sacrifice starts with
1. Qh5!
Honestly, I can’t believe I didn’t start with this move, but, as usual, it was due to initially overlooking a knight controlled square. I had it in my head that Kg8 was possible for black. Continuing:
1. …..Ke7 (Ke6 2.Rge1#)
2. Rg7
Now, the move works and the rest is pretty brute force:
2. …..Ke6 (Rf7 3.Qf7#)
3. Qe2
Plays itself, really- forces the king out and away from any potential defenders. Continuing:
3. …..Kf5 (only move)
Here, I think white mates with at least two other moves (probably more than two), but they are longer than the asked for 8 move mate. Continuing:
4. Qg4 Ke5 (only move)
5. f4
Again, plays itself because it drives the black king further and further from friends and family. Continuing:
5. …..Ke4 (only move)
6. f5
For me, other than the first move, this one took the longest to find (a couple of minutes). I played briefly with Qg2 and Qe2, but rather than take at f4, the black king can delay the mate by returning to f5 and using the white pawn as a shield for a couple more moves. Now, both black replies are mates in a total of 8 moves:
6. …..Ke5 (Ke3 7.Re1 Kf2 8.Qe2#)
7. Qe2 Kf4/f5
8. Rf1#
So tempting to zap that black Queen…but that doesn’t achieve checkmate in 8. Here is the line (I think):
1. Qh5+ Kxe7
2. Rxg7+ Ke6
3. Qe2+ Kf5
4. Qg4+ Ke5
5. f4+ Ke4
6. f5+ Ke5 (took me a while to get this)
7. Qe2+ Kxf5
8. Rf1# 1-0
Couldn’t stop wondering though….would this ever be a real situation? Black’s pieces never seemed to have moved out of the 8th rank but the a-pawn came all the way down. Just an observation.
Qh5+ Kxe7
Rxg7+ Ke6
Qe2+ Kf5
Qg4+ Ke5
f4+ Ke4
f5+ Ke5
Qe2+ Kxd5
Rf1++
that took a long time.. then i finally saw to swing the rook from the back to f1.. difficult problem..
I can’t quite visualize that far in my head but I think this is the start
Qh5+ Kxe7 (Ke6 Rge1#) Rxg7+ Ke6 (Rf7 Qxf7#) Qh3+ Ke5 (only move) f4 and it gets a little hazy
