How is the desperate Rh8 check hard to find?
Rh8+ will lead to all sorts of fun stuff. 🙂
1Rh8+ 2Rh8 3Qh6 mate
1. Rh8+ Bxh8
2. Rxh8+ Ng8 (Kg7, 3. Qh6#)
3. Qxd6+ Ke8 (Kg7, 4. Qh6#; Re7, 4. Qxe7#)
4. Rxg8+ Bf8
5. Rxf8#
1. … Ng8
2. Qxd6+ Ke8 (Re7, 3. Qxe7#)
3. Rxg8+ Bf8 (Rf8, 4. Qe7#)
4. Rxf8+ Rxf8
5. Qe7#
greets, jan
I see two variations here:
A)
1. Rh8+ Bxh8
2. Rxh8+ Ng8 (Kg7 Qh6#)
3. Qxd6+ Ke8 (Re7 Qxe7#)
4. Rxg8+ Rf8
5. Rxf8#/Qe7#
B)
1. Rh8+ Ng8
2. Qxd6+ Ke8 (Re7 Qxe7#)
3. Rxg8+ Bf8 (Rf8 Qe7#)
4. Qe6+ Re7
5. Qxe7#
1. Rh8+ Bxh8
2. Rxh8+ Ng8
3. Qh6+ Rg7 (3. .. Ke8 4.Rxg8+ Kd7 (4. .. Rf8 5. Qe6#) 5. Qe6+ Kc7 6. Qxf7#)
4. Qxd6+ Kf7 (4. .. Ke8 5. Rxg8+ Rxg8 (5. .. Kf7 6. Qe6#) 6. Qe7#)
(4. .. Re7 5. Qxe7#)
5. Qe6+ Kf8
6. Rxg8+ Rxg8
7. Qe7#
1. Rh8+,Bxh8 2. RXh8+, Ng8 (Kg7 loses immediately to Qh6#) 3. QXd6+, Ke8 (Re7 loses to QXe7#) 4. RXg8+, Rf8 5. RXf8+
Since Black threatens mate on b2, White must mate himself, and give checks with every move:
1. Rh8+ Bxh8
1. … Ng8
2. Qxd6+ Ke8 (Re7 3.Qxe7#)
3. Rxg8+ Bf8 (Rf8 4.Qxe7#)
4. Rxf8+ Rxf8
5. Qxe7#
2. Rxh8+ Ng8
2. … Kg7
3. Qh6#
3. Qh6+!
3. Qxd6+ would give the black king the square g7, and now h6 is guarded by the black knight.
3. … Rg7
3. … Ke8
4. Rxg8+ Kd7 (Rf8 5. Qe6#)
5. Qe6+ Kc7
6. Qxf7#
4. Qxd6+ Ke8
4. … Kf7 (Re7 5.Qxe7#)
5. Qe6+ Kf8
6. Rxg8+ Rxg8
7. Qxe7#;
5. Qe6+ Kf8
6. Rxg8+ Rxg8
7. Qxe7#
It’s Rh8+
There are two main lines:
1a .. Ng8 and 1b .. Bxh8
2a. Qxd6+ .. Ke8 (Re7 3.Qxe7#)
3a. Rxg8+ and mate in two moves.
2b. Rxh8+ .. Ng8
3b. Qh6+ .. Ke8 (3c .. Rg7)
4b. Rxg8+ with easy mate patterns…
4c. Qxe6+ .. Ke8 (Re7 5.Qxe7#)
5c. Rxg8+
1Rh8+ Bxh8
2Rxh8+ Ng8 (2.. Kg7 3Qh6#]
3Qh6+ in order to block g7
3….. Rg7
4Qxd6+ Kf7 [or (a)]
5Qe6+ Kf8
6Rxg8+ Rxg8
7Qe7#
(a)3…. Ke8
4Rxg8+ Rxg8
5Qe7#
Even 1… Ng8 does not help.
Rh8 Bh8 Rh8 Kg7 Qh6 mate?
To Jan:
We found almost the same two solutions, but small differences:
A)
4. Rxg8+ Bf8?
The bishop was gone, you must mean Rf8.
B)
You wrote:
4. Rxf8+ Rxf8
5. Qe7#
I wrote:
4. Qe6+ Re7
5. Qxe7#
Both seem correct to me (in my line black king is stopped by black bishop, in your line by rook).
Is it right?
When I post now, I get the random text “puremove”, nice 🙂
Dear friends,
I thought fajac used microsoft word and pasted the contents here.I tried but could not succeed.Then I thought it must be html tag,failed twice but used google search to find proper usage.
pht,
you are right. i usually do this without a board, which sometimes leads to mistakes like this. there were several ways to mate in this case. good, that it seems we found the shortest ones this time! let´s do it again next time.
greets, jan
