Jul-19-11  abuzic: <25.Ng5> (25.e6! probably wins faster) <25...Rab8?> (25...Qd8 offers some resistance) <26.Qe4 g6 27.hxg6 hxg6?> puzzle position, and it is #4: 28.Rh8+ Kxh8 29.Qh1+ Bh6 30.Qxh6+ Kg8 31.Ne7#.

The puzzle may start on move 26: white to play, #12. It has 2 solutions: 26.Qe4 (or Qd3).

26.Qe4
26...g6 and 26...Nc3+ lead to longest #11

One variation: 26.Qe4 g6 27.hxg6 Rc7 28.Rxh7 Nc3+ 29.bxc3 bxc3+ 30.Ka1 f6 31.Nh6+ Bxh6 32.exf6 Qxa2+ 33.Kxa2 Rb2+ 34.Ka1 Rb1+ 35.Rxb1 Rxh7 36.gxh7+ Kh8 37.Nf7# (another quicker mate: 28...fxg6 29.Ne7+ Rxe7 30.Rxh7 Rxh7 31.Qxg6+ Bg7 32.Qe6+ Kh8 33.Nf7+ Kg8 34.Nh6+ Kh8 35.Qg8+ Rxg8 36.Nf7#)

;-26...Be7, #10
;-26...Kh8, #8
;-26...all other moves, #2d

Jul-19-11  zb2cr: Simple. 28. Rf8+ forces the King onto the Rook file, were White can check with his Queen, 29. Qh1+. White could even afford to show off by playing 29. Rh1+, Bh6; 30. Rxh6, Kg8; 31. Rh8+, Kxh8; 32. Qh1+, Kg8; 33. Qh7+, Kf8; 34. Qh8#.
Jul-19-11  DrGridlock: <rilkefan: Pretty surprising that Black played KxR...>

What other moves do you suggest for black?

Jul-19-11  Patriot: I didn't solve this one by following the "check, capture, and threat" approach exactly--28.Rh8+ looks suicidal. But seeing that the black king is completely immobile I looked at 28.Rh8+ a little closer--just long enough to see that 28...Kxh8 29.Qh1+ leads to mate.
Jul-19-11  sevenseaman: Yes <morf> Larsen vs Spassky, 1970 is excruciatingly executional. Its like the man in the electric chair being able to see the finger on the 'Death' button.
Jul-19-11  solskytz: Reminds me of an old article by Israeli Psychologist and FM Amatzia Avni, on an "Attacking retreat". There too, there was a move White Queen from e4 to h1, with 'nuclear' annihilation, just like here (although there at least the opponent had a choice between getting mated or losing his Q for a bishop of his choice - certainly in a kinder vein...)

YEAH!! I found it in 3 or 5 seconds.

Another YEAH - I finally managed to top 2200 on Chesscube.com - took A LOT of trying and I didn't believe that I was actually good enough to make it. Big satisfaction!

Got there an opponent with 2263 - one of those big, formidable rating that you don't think you can do anything against... and you feel like something of a thief if you manage to clip away a win or two - and I actually beat him 12 games to 7 - some of them very interesting, some nice intuitive sacrifices where I keep playing down material for a long time without seeing anything forced... and winning!

Isn't that happiness?

Sure is.

Jul-19-11  solskytz: Hey - it's true that I'm using ALL CAPS for some words in my postings... but I'm NOT (repeat - NOT) a sock puppet of life master AJ! So don't even start with this (lols)

  kevin86: A quick mate in three (ok,four,if you count the bishop's vain interposition)

1 rook to the end of the file

2 queen to the southeast corner

3 Q to h7 mate!

  Once: For a game that is hundreds of years old, chess is also the first game to embrace 24th century transporter technology.

We join the crew of the starship enterprise in the board room. If the original star trek was "to boldly go", Voyager was "to boldly go home", Deep Space Nine was "to boldly stay in one place", then Star Trek the next generation's mission was "to boldly have a meeting."

And that is indeed what they are doing when we join them - having a meeting, complete with powerpoint presentation, flp-chart paper, and post-it notes covering the walls which they all voted for with little coloured dots.

Captain Jean-Luc Picard, revelling in his role as sexiest bald man in the Universe, tugged at the bottom of his lycra tunic and looked around at his senior staff. "Options?" he asked.

"I say we should attack at once," growled Worf, complete with stick-on, Kling-on forehead. "Maybe today is a good day to sacrifice a knight on f7."

"I do not think that would be a good idea," said counsellor Deanna Troi. "I am sensing a good deal of hostile feelings on the queenside."

William Ryker, First Officer, serial womaniser and occasional beardie, looked wistfully at Deanna. "If only we could find a way to beam a landing party to h7!"

"I am afraid that would not be possible," said Commander Data. "The square h7 is shielded by two pieces. It would take 32.7 seconds to break through."

The chief engineer, Jordi LeForge, had a brainwave. "I've got it!" he cried. "We bounce the transporter beam off the deflector dish. That way we get around the shielding and beam to h7 directly."

"Can that be done?" asked Picard.

"I think so. I'll need to fire off a photon torpedo from h1 first, then displace the queen through the neutrino vortex via the heisenburg compensator."

Everyone in the room nodded wisely, as if to pretend that they understood all of that.

"Make it so," said Picard.

28. Rh8+ A photon torpedo.

28...Kxh8 The enemy ship is forced to drop her shields.

29. Qh1+ The transporter beam is bounced off the deflector dish.

29.... Kg8 In a desparate attempt to escape the enemy engages a cloaking mechanism.

30. Qh7# The queen landing party materialises on h7 and the credits roll.

Jul-19-11  sevenseaman: Hmm! Crazier than an actual nut. Good to see you back <Once>. Welcome is ok or you posting from another Galaxy? Whats the Voyager's story?

A gem of a post today.

Jul-19-11  geeker: Not that hard, but the backward move 2.Qh1+ made it tougher and more interesting than the usual Tuesday.
Jul-19-11  fyad reject: considered and discarded the right move because i couldnt find the Qh1 continuation - all i could see was Rh1 which basically just throws away a rook for nothing

looked at 28. Ne7 for a while because Bxe7 seems forced, but couldnt find a response

Jul-19-11  Creg: <Once> Yep, that pretty much sums it up, and as I'm a Star Trek fan, I'd also say that you know their tactics all too well when it comes to space battles... :)
Jul-19-11  more unto the breach: I have to break my habit today of anonymity and post for the first time on CG. Over the last three years, I have been quietly marveling at the unique yet humble wit of <Once>'s posts. Reading his work has been my morning tradition. Always a seamless mixture of wit and analysis, <Once>'s writings are remarkable! Today's tale of TNG personalities, brings out my inner fan boy of Jean Luc and friends, and for my first post, I say "Make it so" to the 'Number One' bard of chess.

  Gilmoy: <M.Hassan: 28.e6 Nc3+ 29.bxc3 bxc3+ 30.Ka1 Qa3 31.exf7# <sevenseaman: 30..Qxa2+ 31.Kxa2 Rb2+ 32.Ka1 Rc7 And now exf7+ will not work ...>> 33.exf7+ Rxf7[] 34.Nxf7 untouchable (Kxf7 35.Qe6#). After 34..gxf5 35.Qxf5 White has QR for P, and Black has only one spite-check before Qh7#. If 30..f6 <undermines g6> 31.Ne7+ is a cute variant of Damiano, with the clearance-sac being an N instead of the R.

So 28.e6 isn't the fastest mate, but it still wins.

Jul-19-11  BiteByBits: did black miss a chance here??

on 26. Qe4? Nc3+ (threaten to fork queen) 27. bxc3 bxc3+ (discover) 28. Ka1 (28. Kc1? is obviously bad due to Qa3++) Rb2! 29. Qc4 (a3? falls to c4!)Rcb8 and i think black might have a chance?

it took like 1 minute but the puzzle was easier than i expected, i thought at first it was a knight sack and then a discover but then i saw that the knight trapped the king and the only thing missing was that we have to take advantage of the queen's access to the h-file to checkmate.

Jul-19-11  stst: Easy but also easily misleads...the N's don't need to move! 28.Rh8+ KxR (forced)
29.Qh1+ Kg8

(if Bh6 trying to get loose, 30.Qxh6+ Kg8, 31.Qg7#)

30.Qh7#

<Crucial is 29.Qh1+, good that this Q's in the diagonal end of the square e4\h1, and can get to h1 to take a good position...>

Jul-19-11  alexrawlings: <BiteByBits: did black miss a chance here??

With the assistance of Fritz, in your line at 28.. Rb2 white has 29 Nh6+ which forces mate. Although black gets close he can't mate before white does.

So I guess the answer is no, black didn't miss anything!

Jul-19-11  KokeFischer: You can delay mate to try to amaze a mate but if you follow Lionnais' criterias for beauty in chess, you have to deliver mate as quickly as possible.

Jul-19-11  BOSTER: In such sharp position when all white pieces are on the king's side against black king with one defender bishop , but black all pieces on the another side of the board only one tempo decides everything. This is the position after white played 25.Ng5. Of course the royal fork which was hanging in the air is very attractive, but if you are thinking about defense it was necessary to play Qd8, chasing the knight on g5, or Qb5 with threat Nc3+.

Jul-19-11  WhiteRook48: 28 Rh8+ a two second puzzle
Jul-19-11  abuzic: <abuzic:...One variation: 26.Qe4 g6 27.hxg6 Rc7 28.Rxh7 Nc3+ 29.bxc3 bxc3+ 30.Ka1 f6 31.Nh6+ Bxh6 32.exf6 Qxa2+ 33.Kxa2 Rb2+ 34.Ka1 Rb1+ 35.Rxb1 Rxh7 36.gxh7+ Kh8 37.Nf7# (another quicker mate: 28...fxg6 29.Ne7+ Rxe7 30.Rxh7 Rxh7 31.Qxg6+ Bg7 32.Qe6+ Kh8 33.Nf7+ Kg8 34.Nh6+ Kh8 35.Qg8+ Rxg8 36.Nf7#)>

I must correct the inaccuracy, it should read:
-One variation: 26.Qe4 g6 27.hxg6 Rc7 28.Rxh7 Nc3+ 29.bxc3 bxc3+ 30.Ka1 f6 31.Nh6+ Bxh6 32.exf6 Qxa2+ 33.Kxa2 Rb2+ 34.Ka1 Rb1+ 35.Rxb1 Rxh7 36.gxh7+ Kh8 37.Nf7#

-Another variation: 26.Qe4 g6 27.hxg6 Rc7 28.Kc1! Nc3 (28...fxg6, see later) 29.Rxh7 Ne2+30.Kd2 b3+ 31.c3 Qxc3+ 32.bxc3 Ng1 33.gxf7+ Rxf7 34.Ne7+ Rxe7 35.Qg6+ Rg7 36.Qe6+ Rf7 37.Qxf7# (another quicker mate: 28...fxg6 29.Ne7+ Rxe7 30.Rxh7 Rxh7 31.Qxg6+ Bg7 32.Qe6+ Kh8 33.Nf7+ Kg8 34.Nh6+ Kh8 35.Qg8+ Rxg8 36.Nf7#)

Apologies..

  tpstar: 26. Qe4 was a clever move which set up the combination by threatening 27. Nh6+! gxh6 28. Qxh7#, but also preparing the deadly retreat 29. Qh1+ mating.
