Oct-05-11  gofer: Errr... I am stumped. I like Re3 and Be2 both of which tempt the black queen to take the loose pawn on d5 and then succumb to a horrible attack, when white plays Rad1. I also like Bc6 but I am not quite sure why...

Okay decision time, OTB I would play <17 Re3> this not only solidifies my king's defenses to stop any silly threat of stalemate, but attacks the queen AND helps me to double my rooks on the e file...

But after an even longer time, I finally see the interference move that I have been missing. Why are these so difficult to find!!!???

<17 Be8 ...>

17 ... Qf5
18 Re6!! Rxe8
19 Rxe8+ Rxa8 winning

19 Qxe8+ Kc7
20 Qe7+ Kb6
21 Qxd6+ Kc5
22 Qd7+ Kc4
23 Qa4+ Kxd5
24 Qd7+ Kc4
25 b3+ mating

17 ... Kc7
18 Re7+ Kb8
19 Qd7 winning

<17 ... Rxe8>
<18 Rxe8 Kc7>
<19 Rxa8> winning

Oct-05-11  Patriot: <LMAJ> I'm seeing 1.Ng5. For example:

A) 1...Nd6 2.Qe6+ Nf7 3.Qxf7#

B) 1...Qh4 2.Qxe8#

Black is essentially "hog-tied".

<agb2002> You wrote: <Black would probably consider 17... Be5...>

I'm missing something in your logic here as 17...Be5 allows 18.Qd7 mate. Are you referring to another variation? I followed your subsequent analysis: very good>

Thanks <morf>, my second paragraph normally deals with the threats or plans the opponent (that is to say, the side not to move) might be concocting.

In this case I didn't see a direct threat so I tried to imagine how Black could improve its position if he had the opportunity, in the case White played a dull move or even a second best move.

1.Ng5 fails to 1...Qh5!! (No mate in three now, I think.)

This is just one of several "false tries" that I warned you about.

Oct-05-11  LIFE Master AJ: 1.Ng5 was just one (of several) ideas that we looked at.

  kevin86: The key move here is 18 Re6!,slamming the door on the helpless queen.
Oct-05-11  Jose Ortiz Elias: Dear chessfriends: I'm a new user in this page, but I have previously followed your very interesting posts and conversations. I'm very happy to chat with you about the wonderful world of chess. On today's puzzle, I think you have already told everything concerning the solution.
Oct-05-11  tbentley: I gave up too quickly before seeing Re6.

<LMAJ>The first thing I notice is if black was to move, it would allow Qxe8# or N(x)f6#.

1. Kd7

A) 1...Qxh7 2. Qxe8#

B) 1...Nf6+ 2. Nxf6+ Kf8 3. Qe8#

C) 1...Nd6 or Nc7 2. KxN Qxh7 3. Qe8#

Oct-05-11  Nullifidian: Solving this was the work of a moment.

17. ♗e8! Δ ♕d7#

If 17... ♖xe8 18. ♖xe8+ ♔c7 19. ♖xa8

Where White is up two rooks for a bishop.

Black's slightly better option is

17... ♕f5/h3 18. ♖e6! ♕g4+ (♙fxe6?? 19. ♕d7#} 19. ♕xg4 ♙fxe6 20. ♗a4

And White is up a queen for a rook.

Oct-05-11  Nullifidian: <Life Master AJ: Here is one position for you:

"White to move and mate in three.">

I like this puzzle because it's counter-intuitive, but not too hard if one figures out the theme. The key for me was "What if 1... ♕xh7?". It doesn't feature in any of the mate in 3 answers, but it helped me figure out the mating pattern.

1. ♔d7! ♘f6 2. ♘xf6+ ♔f8 3. ♕e8#
My favorite variant is:
1. ♔d7 ♘c7 2. ♔xc7! ♕xh7 3. ♕e8#
The same pattern works for 1... ♘d6.

Oct-05-11  Nullifidian: By the way, there's a nice puzzle-like sideline if you do the obvious thing and save the knight.

1. ♘g5 ♕h5 2. ♕xh5 ♘f6


click for larger view

Now the fastest move to win is:

3. ♕h1!

3... ♙g6 4. ♔xf6 ♔f8 5. ♕a8/h8#
3... ♘d5+ 4. ♕xd5 ♔h8 5. ♕a8#

  Once: This easy/hard thing is a bit of a red herring. It all depends on the individual.

That is because the winning line uses two moderately unusual but not unique winning ideas.

The first is 17. Be8, where the bishop shoots past the mating square (d7) and then protects that square by looking over his shoulder. Bishops don't often do anything useful backwards, so that one can be a little hard to see.

The second is moderately unusual move is 18. Re6. The rooks puts itself en prise, but because it is protected by the d5 pawn black cannot recapture with his queen. And 18...fe self blocks the black queen's path back to d7.

Are these two moves easy or hard? Well, that depends on you. If you've seen that sort of thing before then the solution doesn't take long to spot. Then, if you're into that sort of thing, we can trade boasts about how many milliseconds we saw it in.

Or maybe, given what scientists are now telling us about neutrinos and Einstein may have been wrong about E=MC2 so perhaps time travel is possible, perhaps someone will say that they spotted the solution yesterday...

But if you haven't seen these sorts of tricks very often before, I can understand how some people will find it hard. No matter how commonplace and hackneyed a solution might seem to us, we need to recognise that some will be seeing these tricks for the first time.

And the beauty of revelation can be a real joy to be envied.

Oct-05-11  sevenseaman: <LMAJ>'s puzzle is tough but I think I got it;

1. Kd7 Nc7 2. Kxc7! Qxh7 3. Qe8#

I am still looking for variants. Will post if any found.

Oct-05-11  sevenseaman: Here is one more;

<1. Kd7! Nf6 2. Nxf6+ Kf8 3. Qe8# > but I see <Nullifidian> has posted both before me. Still I had the pleasure of finding these. A very good puzzle. <1. Kd7> is quite 'out of the box' thinking.

Oct-05-11  M.Hassan: "Medium/Easy" White to play 17.?
White is a pawn down.
I spent time unsuccessfully on this puzzle. The reason being that 17.Be8 caught my eyes at the very early stage and I thought to myself "what if Black short castles?" and I could'nt lay out a solution until such time that I realized that the King is not on its original position of e8 and have moved and has lost the right of castling and that was after having seen the game.

Chess blindness!!

Oct-05-11  Patriot: <chrisowen> Why not write posts like this anymore? This was early 2010. I just can't understand your posts now.

<chrisowen: Hey pal is time it or did he just get outplayed? Is that a viable state black can hold? White is railing against Ng5+, the rushing in of the knight is too hasty, h6 gets the beers he bargained for. Dxe4 Bxe4+ Kg8 Qd3 is like mountain dew refreshing the attack. Whilst black does plod onwards 14.g4 is gold dust. Wrestling an angel like Gofshtein requires patience yet Tseitlin's pieces are a rabble ringed in the queenside. White rampages like a lion in zion, you tell a vivid picture via 10.h4 of spring.>

  kamalakanta: I think Chris either was hit in the head in an accident, or something terrible happened in his life, and he was left muttering....'cause I can't understand what the heck he is saying!
Oct-05-11  BOSTER: Is this correct puzzle?
After 17.Be8 black should play b5.
Now if 18.Qxb5 Qg4+ with draw
if 18.Bxb5 Rc8 19.Qb5+ Rc7
if 18.Qb5+ Kc8 19.Qa6+ Kd8.

I had a look at that line. Black holds on a while but his King is helpless.

17. Be8 b5 18. Qa5+ Kc8 19. Qa6+ Kd8 20. Qxd6+ Kc8 21. Bd7+ Kb7 22. Bc6+ Ka6 23. BB7+ Kxb7 24. Re7+ Kc8 25. Qc7++

Oct-05-11  darksquare67: The posts from <chrisowen> remind me of the Viagra spam I get. They're full of plausible but meaningless text designed to fool my ISP's content filter. But with <chrisowen> we have to read the gibberish without even having the opportunity to buy the Viagra (or drain-cleaner, whatever).

"White to move and mate in three."

1.Kd7!! Nc7; 2.Kxc7! Qxh7;
I think that this is Black's only legal move.

3.Qe8#. 1-0

Some false tries:

1.Ng5!? Qh5!

1.Qh5, g6!

1.Ke6? Nc7+

Oct-06-11  LIFE Master AJ: Or 1.Kd7!!, Nf6+!?; 2.NxN/f6+, Kf8▢; 3.Qe8.
Oct-24-11  KingV93: <LMAJ>

In regad to the puzzle posted below:
White to move and mate in 3

As I had posted in your forum:

I would try ♔xe8,♕xh7,♕f7+,♔h8,♕f7#

Nobody seems to see this as correct, what am I missing?

Thanks again for the interesting puzzle.

Oct-24-11  KingV93: Ah, I see. The Black Queen simply blocks the check on g8. I knew there must be something I overlooked.

Good puzzle.
