Lenya Gristmilli grinds out another one:
1. Be6 fxe6 (1. … Rh7 2. Qd8+ Ne8 3. Qe7+ Kg8 [3 … Kg7 4. Qxf7+ Kh8 5. Qxh7#] 4. Qxe8+ Kg7 5. Rxf7#) 2. Qd8+ Ne8 3. Qe7+ Kg8 4. Qf7#

Be6 seems to result eventually in a mate:
1. Be6 fxe6
2. Qd8+ Ne8
3. Qe7+ Kg8
4. Qf7#
1. … Rxb2
2. Qa1+ Ne8 (Kg7, 3. Rxf7#)
3. Rxf7+ Kg8
4. Qxe8#
1. … Ne8
2. Rxf7+ Kg8
3. Rd7+ Kf8
4. Qb4+ Rc5
5. Qxc5+ Nd6
6. Qxd6+ Ke8
7. Qe7#
1. … Kg7 (Kg8, 2. Qd8+, Ne8, 3. Qxe8#)
2. Rxf7+ Kg8
3. Qd8+ Ne8
4. Qxe8#
1. … Rc8
2. Rxf7+ Kg8
3. Rb7+ Kf8
4. Bxc8 with the threat of Qd8+
greets, jan
1. Be6
Now black has multiple options, none of which work.
Option 1:
1. … fxe6
2. Qd8+ Ne8
3. Qe7+ Kg8
4. Qxe8++
Option 2:
1. … Rh7
2. Qd8+ Ne8 (Kg7 3. Rxf7++)
3. Qe7+ Kg8 (Kg7 4. Qxf7++)
4. Qxe8+ Kg7
5. Qxf7++
Option 3:
1. … Kg7
2. Rxf7+ Kg8
3. Qd8+ Ne8
4. Qxe8++
Any other move by black (e.g. Rxb2) in reply to 1. Be6 follows a pattern similar to Option 2 above.
bishop e6 and it’s all over but the cryin’.
Hi Susan Polgar,

simple example One.
=================
1.Be6 Qh1
2.Qd8+ Ne8
3.Qe7+ Kg7
4.Qf7++ Mate.
Simple example two
==================
1.Be6 f*Be6
2.Qd8+ Ne8
3.Qe7+ Kg8
4.Qf7++ Mate
By

Be6 !
1. Be6! threatens Rxf7+ and Qa8#.
1. … fxe6
I see only one alternative:
1. … Rh7 securing square f7
2. Qa8+ Kg7
3. Rxf7#
2. Qb4+!
2. Qa8+ Ne7!
2. … Kg8
2. … Ke8
3. Qe7#
3. Qe7
and Black can only delay mate on g7 or f7.
Let’s try 1. Be6 (threat: Rxf7+) and see if black can defend.
1. Be6 sets up the mate, with the rook coming to f7 and the queen to d8 or (a8). 1. … fxe6 fails to 2. Qd8+ Ne8 3. Qe7+ Kg8 4. Qxe8#. Black has no interference, only the desperate 1. … Rc1+ 2. Ka2 Qxb2+ 3. Kxb2 Rc2+ 4. Kxc2 Nxe3+ 5. Kc1, and Black’s gun is empty (5. … Rh7 6. Qd8+ Ne8 7. Qe7+ Kg7 (7. … Kg8 8. Qxe8+ Kg7 9. Rxf7#) 8. Qxf7+ Kh8 9. Qxh7#).
The immediate checks don’t work but Be6 threatening Rxf7+ and Qd8+ is a killer.
Be6 fxe6 Qd8+ Ne8 Qe7+ Kg8 Qf7#
Be6 Rh7 Qd8+ Kg8 Rxf7#
Be6 Rh7 Qd8+ Ne8 Re7 Kg7 Rxf7+ Kg8 Qxe8#
There is no time to waste with checks from the 8th rank (I tried them out, but after Kg7, white has either a rook or queen attacked by the h8 rook and loses an important tempo). It is critical to clear the 7th rank for the rook and put on a double attack on the f7 pawn. The rest is just calculation:
1. Be6 fe6 (alternatives below)
2. Qd8 Ne8
3. Qe7 with mate on the next move.
At move 1, it will do black no good to block the 8th rank with the knight preemptively:
1. …..Ne8
2. Rf7 Kg8
3. Rd7 Kf8
4. Qb4 with mate to follow in no more than three more moves.
At move 1, black can’t even muck things up by taking at b2:
1. …..Rb2
2. Rf7 Ke8 (Kg8 variation above)
3. Qa8 with mate in one.
There are other sacrificial delays I haven’t covered, but there is no defense against the mate.
Madam Susan, I have a suggestion for you regarding comments on tactics page. I feel that the comments should not be visible to the viewer who is solving the puzzle. It should be made visible only after he posts the comments or else he will be seeing the comments before he solves (Something similar to your Vote concept. The percentage of votes will be visible only after one votes)
Note from Lenya Gristmilli to Anonymous who made suggestion to Susan that comments should only be visible to poster of comments only after he/she has posted the comment:
It is a good character builder to refrain from reading comments until one is sure that one has the correct solution. Surely if you can resist the temptation to use a chess program to solve the puzzle, you can resist the temptation to post the solution until after you have solved it.
My practice is to put the solution into a text file before opening the window for posting solutions. Then I just cut-and-paste the solution into this window. That way I’m never distracted by anyone else’s comments, unless I want to be.
(A really good time to look at the “solutions” is to look when only a few have there comments posted online. You can be sure then that you a looking at the incorrect solutions. That can be a lot of fun. But personally, I don’t look at any of the comments until after I’m sure I have the solution, or until I’m so desperate that I have given up solving the problem.)
But, I apologize in advance for being so unGRaceful in pointing this out. GRistmilli deserves all the GRimaces she receives on this one.
🙂 GRin 🙂
