White to move. How should white proceed?
Source: ChessToday.net
Elementary,my dear Watson!
1Rg8+ Kxg8
2Qg1+ Kg8
3Qg7+ Ke8
4Qg8+ Kd7
5Qxf7+ Kd8
Now what,my dear son? I want to check from e7 but the R is there.So we start all over again.
1Bxd6+ Rxd6
We now follow the above sequence with
2Rg8+ and end up with
6… Kd8
7Qe7#.
{In the game, Vallejo Pons played 1. Rg8+, but I like 1. Bxd6+ better.}
1. Bxd6+ Rxd6
(1. .. Ke8 2. Rg8+ Kd7 3. Rxc8 Kxd6 (3. .. Kxc8 4. Qc7#) 4. Qxc6#)
2. Rg8+ Kxg8 3. Qg1+ Qg4
(3. .. Kf8 4. Qg7+ Ke8 5. Qg8+ Kd7 6. Qxf7+ Kd8 7. Qe7#)
4. Qxg4+ Kf8 5. Qc8+ Be8
(5. .. Rd8 6. Qxd8+ Be8 7. Qe7+ Kg8 8. Qxe8#)
6. Qc5 h6 7. Qxd6+ Kg8 8. Qd2 Bd7
(8. .. Kh7 9. Qg2)
9. Qxh6 a5 10. Qg7#
Rg8+
Hi nice one,
Rg8 + and then after Kxg8 2. Qg1 + followed by either checkmate on g7 or check on g7 then another check on g8 then Qxf7 and finally Ba5 with serious game over activity like it nice one thanks for posting
Rg8 followed by Qg1
I’m sure there is a quicker way, but an unstoppable attack comes after
1. Rg8+! Kxg8
2. Qg1+ Kf8 (…Kh8 3. Qg7#)
3. Qg7+ Ke8
4. Qg8+ Kd7
5. Qxf7+ Kd8 (…Re7 6. Qxe7#)
6. Ba5+ Qc7
7. Qxc7+Ke8
8. Qxc6+ Kf8
9. Qd7 is totally winning…
Rg8 as an idea should be obvious:
1. Rg8 Kg8
2. Qg1 Kf8
3. Qg7 Ke8
4. Qg8 Kd7
5. Qf7 Kd8 (or Re7 6.Qe7#)
6. Ba5 Qc7
7. Qc7 Ke8
8. Qd8#
There are a couple of different possibilities. The obvious choice:
1. Rg8+ Kxg8
2. Qg1+ Kf8
2. … Kh8; 3. Qg7 mate
3. Qg7+ Ke8
4. Qg8+ Kd7
5. Qxf7+ Kd8
5. … Re7; 6. Qxe7 mate
6. Ba5+ Qc7
and, for example,
7. Qxc7+ Ke8
8. Qxc6+ Kf8
9. Qc8+ Kf7
9. … Re8; 10. Qd7 and mate in two
10. Qd7+ Kxf6
11. Bd8+ Re7
12. Qxe7 mate
But there is a faster alternative using the same themes:
1. Bxd6+! Ke8
1. … Rxd6; 2. Rg8+ Kxg8; 3. Qg1+ Kf8; 4. Qg7+ Ke8; 5. Qg8+ Kd7; 6. Qxf7+ Kd8; 7. Qe7 mate
2. Rg8+ Kd7
3. Rxc8 Rxd6
3. … Kxc8; 4. Qc7 mate
3. … Kxd6; 4. Qc7 mate
4.Qd8+ Ke6
5. Qe7 mate
I didn’t check this with the computer or using a board; did I miss anything?
1.Rg8 Kg8 2.Qg1 Kf8 3.Qg7 Ke8 4. Qg8 Kd7 5.Qf7 Kd8 6.Ba5 wins
1. Rg8+ K:g8 2. Qg1+ Kf8 3. Qg7+ Ke8 4. Qg8+ Kd7 5. Q:f7+ Kd8 6. Ba5+ and wins.
Rg8+
Qg1+
Qg7+
Qg8+
Q:f7+
and Ba5+ win
I was too hasty.Sherlock Homes would have been home even with
1Rg8+ as shown by Yancey and others.I had missed out 6Ba5+ completely. Of course if I had seen it I would not have noticed 1Bd6+ at all. Also I dismissed 1Bxd6+ Ke8 as black would lose Q especially when white has not sacrificed anything so far.
