White to move. How should white proceed?
1k1r3r/1p5q/1N1p2p1/Q3b1p1/P2p4/3P2P1/4bR2/R4BK1 w – – 0 1
Best continuation maybe is Bh3!…
The plan is simple deviate the queen.
1.Bh3!! Qxh3
2.Qxa8+ Kc7(Rf7+ also wins by Qb7)
3.Rc1+ KingxKg6
4.Rb1+ …
4..Kc7 5.Qxb7++
4..Kc6 5.Qxb6+ Kc5 6.Qb5++
4..Kc5 5.Qa7+ (b6 Qxb6+) Kc6 6.Qxb7+ Kc5 Qb5++
what if the Queen doesn’t capture the bishop.
1.Bh3!! Bg4??
2.Qa8+ Kc7
3.Rc2+ KxK
4.Rb1++
Other move’s
1.Bh3!! Bxg3
2.Rxe2 (same idea) Bh2??
3.Rxh2+-
1.Bh3!! Bxg3
2.Rxe2 Bf2??
3.Rxf2+-
1.Bh3!! Rf8??
2.Qa8+ Kc7
3.RxR+- (case desesperation Qxf3? Qc8+ with same idea capture b7 and check b1 with rook)
1.Bh3 is the best idea against any black move
Since there is a threat of mate somewhere in the region of h1, its clear that forceful moves are needed to avert the danger.
1. Qa8+, Kc7
2. Nd5+
If we get the king to d7, we can take on b7 and exchange queens, save the knight (Nc7-b5 with checks) and take on e2 at the end. So thats i where we want the king to go… therefore,
2. …, Kc6
3. Nb5+
Now, if the king goes to c7, we have Rc1 and the king has to go to d7 (due to Nd5#) and we get what we want.
If the king goes to c5, Qa7+ and we have a mate eventually up the board or in case og b6, simply the same excange up due to Nh6+ to save the Knight.
If the king goes to b6 we will end up with a perpertual with the knight.
1.Bh3!! QxBh3
2.Qa8+ Kc7
3.Rc1+ KxK
4.Rb1+-
or
any other move white proceds with rook c1 (Qa8++)
Moves like …Rc8?
1.Qa8+ Kc7
2.RxR RxR
3.QxR Kxk
4.and maybe protecting the bishop with king or queen, or capturing in e2 any way +-
In case black move .. Bf3 Rxf3!
the bishop can’t be capture, black’s queen have to protect b7.
Find the right plan!? How about 1. Resigns !? That seems to be the most likely “right plan”. But, then, I will not have it said that anyone in our wonderful online club here gave up. It’s really late now Wednesday evening here in California, but what if White plays 1. Bh3, the idea being to both stave off the mate by the Black queen on h1 (for one move), and to deflect the Black queen away from the defense of the 7th rank? That looks really promising. If Black doesn’t play 1. … Qxh3, then the Bishop will be attacking all those squares in the Black camp: c8, d7, e6. I’ll try this out in the morning.
Ah, yes! Thursday morning now, and Bh3 is the “right plan”!!
1. Bh3 Qxh3
2. Qa8+ Kc7
3. Nd5+ Kc6 or [3. … Kd7 4. Qxb7+ Ke6 5. Qf7#]
4. Rc1+ Kxd5 or [4. … Kd7 5. Qxb7+ Ke6 6. Qf7#]
5. Qxb7+ Ke6
6. Qf7#
So, what if the Black queen gives up the mate threat, but continues to guard the 7th rank?
1. Bh3 Qg7
2. Qa8+ Kc7
3. Nd5+ Kc6
4. Rc1+ Kxd5
5. Qa5+ b5
6. Qxb5#
Ah, but there’s a faster way:
1. Bh3 Qg7
2. Rc1 any move
3. Qa8#
Black can also try 1. … Rc8. That looks like a good try.
1. Bh3 Rc8
2. Qa8+ Kc7
3. Nd5+ Kc6
4. Qa5 (a nice deadly “quiet move” threatening Qb5#)
4. … b6
5. Qxb6+ Kxd5
6. Qb3+ Kc5 or [6. … Rc4 7. Qxc4#]
7. Rc1#
This was a really cool problem!
1.Bh3 g4(Bg4)
2.Rc1
OR
1…. Qh3
2.Qa8 Kc7
3.Rc1 Kb6
4.Rb1 with mate to follow
Also
1.Bh3 Bg3
2.Qa8 Kc7
3.Nd5 Kc6
4.Rc1 Kd5
5.Qa5 mate
Hmmm…another reply
1.Bh3 Bd3
2.Qa8 Kc7
3.Rc1 Kb6
4.Rb2
Just cut out the mating attach and it’s all over for black.
1. Bh3 Rc8
2. Qa8+ Kc7
3. Nd5+ Kc6
4. Qa5 b6
5. Qxb6+ Kxd5
6. Qb3+ Kc5
7. Rc1#
test
Please, for the love of god… King = K, Knight = N, stating KxK is an anachronism in chess… also, why would you put ?’s on any move? you should make your best both for white AND black.
Sorry, but I think most your analysis are incomplete and/or redundant in some moves.
1. Bh3!! mate in 12
All moves except Qxh3 or Qd7 are succeeded by 2. Rc1 and the inevitable followup 3. Qa8# (mate in three) so you only need to consider these two, the rest is redundant.
1. … Qxh3 2. Qa8+ Kc7 3. Rc1+ Kxb6 4. Rb1+ Kc5 5. Qa7+
5. … Kc6 6. Qxb7+ Kc5 7. Qb5#
5. … Kd5 6. Qxb7+
6. … Ke6 7. Qf7#
6. … Kc5 7. Rc1#
So I guess taking the bishop isn’t the best for black.
How about the strange 1. … Qd7? just because its odd doesn’t mean it can’t be an effective escape from a sure mate in 7 right?
Of course you can always take the Queen but chess is about taking out Kings, not Queens, you’ll take longer to checkmate if you opt to take the Queen.
1. … Qd7 2. Qa1+ Kc7 3. Nd5+ Kc6 4. Qa5!! (threatening 5. Qb5# and the only move for black is the following) b6 5. Qb5+ Kb7 6. Qxb6+ Ka8 7. Qa6+ Qa7 8. Nc7+! Kb8 9. Rb1+ Kxc7 10. Qxa7+ Kc6 11. Qb7+ Kc5 12. Qb5#
Hope I didn’t miss anything, it’s 6am and I’m nowhere near a chessboard to make things clearer.
Cheers
