Black to move. How can Black save this game?
r5k1/p1QN3p/P5pB/5p2/1P2nP2/3q3P/3n2PK/R2R4 b – – 0 1
1. “Accidentally” knock over the board.
2. Phone a friend (“Hey, Magnus?”).
3. Play a mate in 5 beginning with … Nf3+
1. … Nf3+
alternatives:
2. Kh1, Ng3#
2. gxf3 Qe2+
3. Kh1 Qxf3+
4. Kg1 (or Kh2), Qf2+
5. Kh1 Ng3#
Looks like Nf3+ wins.
Well, it was tempting to play the “obvious” first move,
1. ….Qg3
2. Kh1 Nf2
3. Kg1 Nh3
4. Kh1 Nf2
5. Kg1 Nf3
6. Kf1 Nh2
7. Ke2, and it appears to me that the white king escapes to the queen side. So, the only other move I see to start must be the correct one:
1. … Nf3
2. gf3 Qe2
3. Kh1 Qf3
4. Kg1 Qg3
5. Kh1 Nf2#
and, if white tries
2. Kh1 Ng3#
and, if white tries
3. Kg1 Qf2
4. Kh1 Qf3
5. Kh2 Qg3
6. Kh1 Nf2#
Qg3+ Kh1
Nf2+, Kg1,
Nf3+, Kf1,
…eventually Ra8 will come into play…black shd win this..
Qg3
if Kh1 Nf2
Kg1 Nh3 with mate somewhere in there, i guess
if Kg1 Nf3 with mate following
ag
It seems Black can do more than just “saving” (i.e., draw) the game:
1… Nf3+ 2. gxf3 (2. Kh1 Ng3#) 2… Qe2+ 3. Kh1
(3. Kg1 Qf2+ 4. Kh1 Ng3#; 3. Kg3 Qf2#) 3… Qxf3+
Now,
4. Kg1 Qf2+ 5. Kh1 Ng3#
4. Kh2 Qf2+ 5. Kh1 Ng3#
Now, only 2. Kg3 remains. Then,
2… Ne1+, and now,
3. Kh4 Nxg2+ 4. Kh5 Qf3#
3. Kh2 Qg3+ 4. Kh1 Qxg2#
Since the diagram is upside down, it was hard to write the notation correctly 🙁
Of course Nf3+
Kh1 Ng3#
gf Qe2+
Kh1 Qxf3+
Kg1/h2 Qf2+
Kh1 Ng3#
Nf3+ wins.
1. … Qg3 does not work as the checks run out and white gets time to play his threat, Nf6+ followed by Qg7 mate.
BUT – is there another check for black that hasn’t yet been mentioned or analyzed? Why yes there is…
Black moves Nf3+ to win.
pawn takes f3, qe2+, king h1, qxf3+, king g1, qf2+, king h1, Ng3#
Black moves Nf3+ to win.
pawn takes f3, qe2+, king h1, qxf3+, king g1, qf2+, king h1, Ng3#
another approach
Qg3+, Kh1
Nf3+. If g2xf3, Qxf3+, Kg2, Qf2#
Nf3+ followed by mate.
Nf3+ etc.
As usual, we start by looking at what the threat to black is. It is very easy to see – a checkmate via Nf6+. followed Qg7. So black needs to either figure out a defence for that or force a mate or draw himself. I stared at the position for some time and found the draw option, which is:
1… Qg3+
2. Kh1 Nf2+ (2. Kg1? Nf3+ 3. Kh1 Qh2# or 3. Kf1 Qf2#)
3. Kg1 Nxh3+
4. Kh1 Nf2+ for a perpetual.
So now that the draw is secured, next is to find if a win is possible. I stared some more and eventually saw it:
1… Nf3+!
2. gxf3 Qe2+ (2. Kh1 Nf2#)
3. Kh1 Qxf3+ (3. Kg1 Qf2+ 4. Kh1 Ng3#)
4. K~ Qf2+
5. Kh1 Ng3#
Which is a forced checkmate in 5.
1 .. Nf3+ works also
If 2.Kh1, then Ng3++
If 2.gxf3 Qe2+ and white can’t stop the mating attacks.
