White to move. How should White proceed?
Bg5
B*g6!
1) Bxg6 appears to do it. Obviously, Black cannot play Rxe1, since 2) Qd8+ will end things quickly.
If the Black Rook moves to f8, the ending is ruthlessly quick again: 2) Bxf7+, and if Rxf7, 3) Re8+ is easy enough, while if Kxf7, 3) Re7+ and 4) Qg5+ look convincing.
Black can delay things only minimally with Bd7, since 2) Bh5 threatens Qg5+. Black must now try f6, but 3) Rxe8+, Bxe8; 4) Qg4+, Bg6; 5) Bxg6, and the rest is easy.
I find that Bxg6 wins in all variations. The Black 8th rank is very weak. Who put the queen there? 😀
White has sacrificed a R to get overwhelming position.Black is behind in development,Q is cornered and K almost in a mating net.White by moving his B from e4 can bring several threats. The best seems to be
1.Bxg6 Bd7
2.Bc2 f6
(2…. f5 3.Rxe8+ Bxe8 4.Qe7 Nd7 5.Bxf5 Bf7 6.Qg5+ Bg6 7.Be6#)
(2…Qc3 3.Rxe8+ Bxe8 4.Qe4 Qg7 5.Qxe8+ Qf8 6.Qxf8#)
(2…. Qg7 3.Bxg7 Kxg7 4.Qxh7+ Kf6 5.Qh6#)
3.Rxe8+ Bxe8
4.Qg4+ Bg6
5.Qc8+ Kf7
6.Qe6#
Alternative for black on 1st move is 1…. Bd6 which I shall take up in next session.
e4Xg6
Here I instantly wanted to try:
1. Bxg6!
Defences that don’t work include:
A)
1. … Rxe1??
2. Qd8+ Re8
3. Qxe8#
B)
1. … fxg6??
2. Rxe8+ Kf7
3. Qe7+(!) Kg6
4. Rxh8 Kxh6 (Kf5 Rf8+ … Qf6+)
5. Qf6+ Kh5
6. Rxh7#
C)
1. … hxg6???
2. Rxe8+ Kh7
3. Bg7+! Kxg7 (only)
4. Qxh8#
C)
1. … Rf8?
2. Bxf7+! (Qe7 Nd7 was less efficient, Bxf8?? was bad)
C1)
2. … Rxf7
3. Re8+ Rf8
4. Rxf8#
C2)
2. … Kxf7
3. Qe7+ (Re7+ should work equally) Kg6 (Kg8 Qxf8#)
4. Qg5+ Kf7
5. Re7#
D)
1. … Nd7???
2. Rxe7+ Nf8
3. Rxf8#
D)
1. … Bd7?
2. Rxe8+! Bxe8
3. Qe7! Nd7/Qg7 (only 2 against Qf8#)
4. Qxe8+ Nf8/Qf8
5. Qxf8#
Then the only defence that black may concider:
E)
1. Bxg6! Be6!
This looks complicated, I will come back to it in next mail.
1. Bxg6! Be6 (enforced)
2. Rxe6!!
A)
2. … Rxe6??/Rf8??/fxg6??
all turn out equally bad as discussed in previous mail.
B)
2. … fxe6
3. Bxe8!
BK is immobile and black must address the double threat 4. Qf4 mating on f7/f8 and 4. Qd8 mating discovered Bh5#.
3. … Nd7 4. Bxd7 … 5. Bxf6#
3. … Qe5 4. Qd8 Nd7 5. Qxa8
C)
2. … Nd7
3. Bxf7+! Kxf7
4. Qh5+! Kg8
5. Rxe8+ Nf7 (Rxe8 Qxe8+)
6. Rxa8 or Qg5+, white wins any way here.
Mate is always the best 🙂
I suggest
1. Bxg6 threatening Rxe8+.
The black rook may not leave the 8th rank because of Qd8 with mate. Taking the bishop is no good either, see:
– 1. … fxg6 2.Rxe8+ Kf7 3.Qe7#
– 1. … hxg6 2.Rxe8+ Kh7 3.Rxh8+ Kxh8 4.Qf6+ and 5.Qg7#
So, the e-file has to be blocked, leaving Qe5 and Be6 as the only options.
– 1. … Qe5 2.Qf6! with the double threat of Qxf7+ -> Qxh7# and Rxe5 -> Qg7# which cannot both be met at once. That leaves
1. … Be6
2. Bxf7+ Bxf7 Forced.
3. Qg5+ Bg6
– 3. … Qg7 4.Qxg7#
4. Rxe8+ Kf7 Forced.
5. Qe7#
Now,
1.Bxg6 Be6
2.dxe6 fxg6
(2…hxg6 3.exf7+ Kxf7 4.Qc4+ d5 5.Qxd5+ Kf6 6.Qf3#)
(2…. fxe6 3.Rxe6 Nd7 4.Qc4 Qb2 5.Rxe8#)
3.Qf4 Qg7
(3… Re7/Rxe6 4.Qf8#)
(3…. Qc3 4.Qf7+ Kh8 5.Qxe8# )
4.Bxg7 Kxg7
5.Qf7+ Kh6
6.Re4 g5
7.Qf6+ Kh5
8.Rh4+ gxh4
9.g4 #
1. Bxg6 Rxe1
2. Qd8#
If 1… Fxg6
2. Rxe8+ Kf7
3. Qe7#
Best option for black is 1… Hxg6
2. Rxe8+ Kh7
3. Bg5+ Kg7
4. Bf6#
All forced moves.
3.
1. Bxg6
1… Rc1 is forced…
2. Bxf7 …….
Rest follows
Doesn’t Bf5 win too?
pht,
The position is such that there are different ways to win after the first move.however your 1st session D)1…. Bd7 is not convincing as 4.Qxe8+ is countered by 4…. Rxe8 as both B & N have moved away from 8th rank.
Fajac,
2…. Bxf7 may not be black’s best defence e.g.
1.Bxg6 Be6 2.Bxf7+ Kxf7 3.Qh5+ Ke7 (3…. Kf6 4.dxe6 Rxe6 5.Bg5+ Kg7 6.Rxe6 Qc8 7.Qh6+ Kg8 8.Re7 wins) 4.Rxe6+ Kd7 5.Qf7+ Kd8 6.Bg5+ Kc8 7.Rxe8+ Qxe8 8.Qxe8+ and white wins but no mate in sight.
Anand Gautam,
I could have addressed you as simply Anand but it would be construed as Vishwanathan Anand and frankly I would not give you so much credit.1.Bf5 as suggested by you may not serve the purpose as it is not dynamic enough compared to 1… Bxg6 as the latter opens g file for white Q and also attacks f7 in many variations.The following lines may not be conclusive but give lack of punch.
1.Bf5 Rf8 2.Qe7
(2.Bxf8 Bxf5 3.Re8 Nd7 4.Rxa8 Nxf8 5.Qe7 Qg7)
(2.Bxc8 Rxc8 3.Qe7 Nd7 4.Qxd7)
2…Nd7 3.Bxd7 Bxd7 4.Bxf8 Rxf8 5.Qxd7
To fajac and Prof. Bhat:
1. Bxg6 Be6
2. Bxf7+! Kxf7 (Best. Bxf6 was NOT forced.)
3. Rxf6! Nd7 (Forced to protect Re8. Rxf6? Qd8+. Rf8? Rf7+ and Qg5+)
4. Qh5+! Kg8
5. Rxe8 Nf8 (Rxe8? Qxe8#)
6. Qg5+! (Rxa8? wasn’t right) Kf7
7. Re7#
Perhaps this is actually the critical line?
If it’s correct, I think this line may be better than 2. dxe6 which branches into more lines than I like.
pht,
Your latest mail:
3. Rxf6! Nd7 (Forced to protect Re8. Rxf6? Qd8+. Rf8? Rf7+ and Qg5+) I think you meant
3. Rxe6! Nd7 (Forced to protect Re8. 3…Rxe6? 4.Qd8+. Re8? 5.Rf7+ and Qg5+)
But how is it possible?4.Qd8+ is not possible because black K is at f7.may be some mix up.
Considering the latest discussed variation after 1.Bxg6 Be6 2.Bxf7+ Kxf7 3.Qh5+ Kf6 4.dxe6
I thought whether my 4…. Rxe6 was in haste as it ultimately resulted in the loss of R by black.Instead I felt whether 4…Qg8 was playable.However that also fails. 4…Qg8 5.Qh4+ Kf5 6.Qf4+ Kg6 7.Qg5#
