Nov-07-12  M.Hassan: "Medium/Easy"
White to play 23.?
White is a piece (Bishop) down

I studied 23.Qh5 but I arrived at a draw conclusion:
23.Qh5 Qe8 the only move defending mate
24.Rxb7 Kg8
25.Qxb5 Qc8
26.Rxb6 Qc1+
27.Qf1 Qb2
28.Qe2 Qc1+
29.Qf1 Qb2
1/2 1/2

I then went for the Knight move that had initially triggered some thought and got better results:

23.Nxe6+
<if...fxe6 24.Qg7+ with mate next move> 23............Ke8
24.Nc7+ Kf8
25.Nxa8 Bxa8
26.Qh5 Qe8
27.Ra7 Kg8
28.Rxa3
White that was behind at the end of move 22, is now ahead by a Rook+pawn for a Bishop but: 28...........Qe4
threatening mate on g2
29.Rxa8+ Qxa8
30.Qxb5 Qxa2
31.g3
White has a better pawn structure and can win.

  FSR: White wins in "Granda" fashion: 23.Nxe6+! Ke8 (23...fxe6 24.Qg7+ Ke8 25.Qf7#) 24.Ng7+ (alternatively, 24.Nc7+ and 24.Rc7 also look winning) 25.Nh5 (threatening 25.Qg7+ Ke8 26.Qxf7#) Bd5 (25...Qe8 26.Qg7#; 25...Ke8 26.Nxf6+ Kf8 27.Qg8#) 26.Qg7+ Ke8 27.Nxf6#.

  FSR: <<White wins in "Granda" fashion: 23.Nxe6+! Ke8 (23...fxe6 24.Qg7+ Ke8 25.Qf7#) 24.Ng7+ (alternatively, 24.Nc7+ and 24.Rc7 also look winning)>

Once: ... With Fritzie's help, how many ways are there to win?

First he says that 23. Nxe6+ is the only first move. Others are equality at best.

After 23...Ke8, he finds three winning moves - 24. Ng7+ (#7), 24. Nc7+ (#12) and <LTJ's> 24. Rc7 (+7.46).>

I rule. For today, anyway; tomorrow is doubtless another story.

Nov-07-12  morfishine: White is down a piece; This is offset by Black's passive rook plus the fact White is on the move, on the attack, and enjoys a positional tactic:

<23.Nxe6+> The Knight is immune due to 24.Qg7+ Ke8 25.Qf7 mate;

<23...Ke8> Forced

<24.Nc7+> Here, White has to be careful: Wrong would be 24.Rd8+ Qxd8 25.Nxd8 Kxd8 26.Qd4+ Kc7 and Black has R+2B vs Q; The main point of 24.Nc7 is to keep the Black King and Queen out of <e8>

<24...Kf8> Practically forced (24...Qxc7 25.Rxc7 is hopeless for Black)

<25.Qh5> Mate threat at <f7>

<25...Be7> The point of 24.Nc7: The Black Queen cannot defend <f7> from <e8>

<26.Qxh7> The mate threat at <h8> is unstoppable; A very interesting final position:

Wow, what a great surgeon-like finish by White! I considered <24.Ng7+> but failed to appreciate the strength of <25.Nh5>

  gofer: White is a piece down, but has a strong attack on the isolated king.

<23 Nxe6+ ...>

23 ... fxe6
24 Qg7+ Ke8
25 Qf7#

<23 ... Ke8>
<24 Nc7+ ...>

At which point black is starting to sweat - profusely.

24 ... Kf8
25 Qh5! mating

Taking the knight is the only way to offer a little resistance!

<24 ... Qxc7>
<25 Rxc7 ...>

and even that path doesn't offer much resistance!

25 ... Bd5?
26 Qd7+ Kf8
27 Qxd5

~~~

Ng7+ was much cleaner!

Nov-07-12  ventricule: I went for 24. Ng7 + and then 25 Qh5, mixing the ideas in both lines. Does it work ? I cannot seem to see an escape for black.
Nov-07-12  zb2cr: Found this one quickly.
Nov-07-12  backyard pawn: <LTJ> I was intrigued by your alternative line: <23. NxP+! K-K1
24. R-QB7! QxR
25. NxQ+ 1-0, as this is promptly followed by 26. NxR .>

In this line, would 24...., Bf8 save the position for Black? I'm almost afraid to ask, as I am prone to miss the obvious.

Nov-07-12  James D Flynn: 23.Nxe6+ Ke8(not fxe6 24.Qxe6 Bd5 25,Qxf6 and the K is forced to move to e8 or g8 whereupon White mates by either Qe7# or Qg7#) 24.Ng7+ Kf8 25.Nf5 Bd5 26.Qg7+ Ke8 27.Re7+ Kd8 28.Qf8#
Nov-07-12  Manoloo: The "Guess the move" must be "21. white to play": Nd4, beautiful!
Nov-07-12  eric the Baptist: Kind of a tough one today. Actually requires 6 moves by white to complete the checkmate.

Shame on you Minnesota. Yet another disgraceful performance at the voting booth.

Nov-07-12  ferri1234: I found 23 Nxe6 Ke8 24 Nc7+ Kf8 25 Qh5 Bd5 26 Qxh7 and white wins. Am I wrong?
Nov-07-12  James D Flynn: OOPS I overlooked the Black B on a3.
23.Nxe6+ Ke8 24.Ng7+ Kf8 25.Nf5 Bd5 26.Rxd5 White threatens to simply move his R back to d7 followed by mate on f7. This threat can be answered by Ra7 , Qb7, Qc7, or Qc8 all fail to 27.Qg7+ Ke8 28.Qg8+ Bf8 29.Nd6+ and White wins the Black Q or in the case of Ra7 the Black B. This is a prosaic win instead of the beautiful mate in the game.
Nov-07-12  Bengambit: You know,in times and games like this,if your "Positional Correct" for a mating attack,go for it. White's first and second ranks is toast,but thanks to black's position his pieces would take forever to get in an good counter attacking position. There is a time when your backside is hanging out,and all you have left is an attack to save your "You Know What" from defeat.
Nov-07-12  David2009: Granda-Zuniga vs R Rodriguez Lopez, 1995 White 23?

White is a piece down so needs to win quickly if at all. 23.Rxf7+ probably won't work, White risks runnning out of checks and has at best a draw by repetition. Black can play to win by 23...Kxf7 24.Qxe6+ Kf8! 25.Qxf6+ Ke8! 26.Qe6+ Be7. Instead 23.Nxe6 CHECK! is much better (if it was not check, Black has the saving Qc8): 23...Ke8 forced (if 23...fxe6? 24.Qg7+! Ke1 25.Qf7#; instead 24.Qxe6? nearly mates but Black has Bd5) 24.Ng7+ and White has at least a draw by repetition so can look for more OTB. Yes the win is there: 24...Kf8 25.Ne6+ Ke8 26.Nc7+ Kf8 27.Qf4 meeting 27...Kg8 or 27...Ke8 with 28.Qxf6 and 27...Kg7 with 28.Nxe6+. Time to check and put the position up on Crafty End Game Trainer:
===
I got some of it- very rich puzzle position. Here it is


click for larger view

set up on Crafty End Game trainer: http://www.chessvideos.tv/endgame-t.... After 23.Ne6+ Ke8 24.Ng7+ Kf8 both 25.Nh5 and 25.Ne6+ Ke8 26.Nc7+ win easily against the EGT: in either variation the robot jettisons massive material to postpone mate.

However this is more luck than skill. Here's the position after the variation 23.Ne6+ Ke8 24.Nc7+ Kf8:

Now my intended Qf4?? runs into - what? (a complete equalising move!) Over to Crafty EGT to find the refutation if you don't spot it from the diagram: link to this variation with White to play is http://www.chessvideos.tv/endgame-t....

You can also find the proper winning move (<Once's> post gives it if you get stuck).

Nov-07-12  JRMenezes: the puzzle should have started from move 21.? not move 23?

  chrisowen: Energy in spades Granda abbott in lighter dig mind you knightd4xe6

in effect rook boy scouted seventh rank it hog in lace garage it her

white in gobble 26.qg7+ mated in too the knight heading resurgence

in cadence 27.Nxf6+ alive to the threats cope right win e7 take f6

an flourish 28.Qxf7#

Nov-07-12  LIFE Master AJ: I guessed 23.NxP/e6+, in about two seconds, (seeing that is Black took, Qg7+ and mate to follow); although I was not sure of the exact follow-up ...

  kevin86: This was much easier than yesterday's.

The knight check is obvious-though the gymnastics of the queen and rook and knight-are less so.

White mates in two more moves.

Nov-07-12  Alphastar: I went with 25. Nf5 instead of the game move 25. Nh5. It seems that my move wins as well, though not as fast (after eg. 25. ..Bd5!?).
Nov-07-12  LoveThatJoker: <Once> Good post and thanks for the kind mention!

<backyard pawn> Thanks for your note! I covered 24...B-KB1 in my solution post.

23. NxP+ K-K1 24. R-QB7 B-KB1 25. Q-N8 , was my line.

Stockfish confirmed that White is winning by a country mile in this line, yet it states that 25. N-N7+ mates.

  agb2002: White has a knight for the bishop pair.

The first idea that comes to mind is 23.Qh5, threatening 24.Qxf7#. However Black can play 23... Be7. A more forcing option is 23.Nxe6+:

A) 23... fxe6 24.Qg7+ Ke8 25.Qf7#.

B) 23... Ke8 24.Ng7+ (24.Nc7+ also wins but it looked slower to me because of 24... Qxc7 25.Rxc7 Bd5) 24... Kf8 25.Qh5

B.1) 25... Be7 26.Qxh7 and mate in two.

B.2) 25... Kxg7 26.Rxf7+ and mate next.

B.3) 25... Bd5 26.Qxd5 Kxg7 27.Qxf7+ Kh6 28.Qxf6+ Kh5 29.Rxh7+ Kg4 30.Rh4#.

  agb2002: According to Houdini 25.Qh5 is mate in six, only one move slower than 25.Nh5.
Nov-07-12  stst: Quite an involved variation.
23.NxP+ ...
IF (A)....PxN, 24.Qg7+ Ke8, 25.Qf7#
IF (B)....Ke8, 24.Nc7+ QxN, 25.RxQ Bc8
26.Qe4+ Kd8 (here: if (i)Be7, 27.QxB#;
or if (ii)Kf8, 27.Qxh7 and mate next on Qh8)
27.Rxf7 Ra4, 28.Qh7 & mate next on Qh8.
Nov-07-12  stst: Saw also Ng7+, should spell out the subsequent analysis too...
