  dzechiel: White to move (30?). White is up a pawn. "Difficult."

I see some forcing moves that may, or may not, lead to something. It starts with

30 g6

Attacking the black queen. Either the pawn must be captured, or the black queen must vacate f7. Since the black queen is holding down g7 to prevent the mate with the white queen, let's consider the capture first.

30...hxg6 31 Rxd8

Another forcing move as black must recapture on d8 to avoid going down a piece.

31...Rxd8 32 Qg5

Now attacking the rook on d8, and threatening moves like Qh6+. So, what does black do with the rook? Probably

32...Rd7

Other rook moves have problems (32...Re8 33 Rxe8+ Qxe8 34 Qh6+ Kg1 35 Qxg7#; or 32...Rf8 33 Re7 Qg8 34 Rxg7 Qxg7 35 Qh6+ Kg8 36 Qxg7#).

33 Qh4+ Kg8 34 Ng5

On the queen again, and she's nearly out of running room. I don't see a good move for black here. The queen can't stop both 35 Qh7+ etc and 35 Re8+.

This may be it. Time to check.

=====

My line differs, but I still like it. Does anyone want to show me the error of my ways?

  a q maclanahan: i think that after 32 Qg5 other rook moves might hold, e.g. 32...Rb6-d6
Jun-18-10  PizzatheHut: How does play continue after 30...Qg8?

  OBIT: This one has me stumped. The move I keep going back to is 30. g6, which looks promising after 30...hg 31. Rxd8 Rxd8 32. Ng5. However, 30...Qg8 and 30...Qc7 both look fine to me.

Well, after 45 minutes I am tired of looking at this. Let me see what I am missing...

  al wazir: After 30. g6 hxf6 I wanted to play the immediate 31. Ng5. If 31.. Bxg5, then 32. Rxb6, and now if 32...Qxf2+ 33. Kh1 Rg8 34. Rxg6, and black has to lose his ♕ or his ♔. If 31...Qc7, then 32. Rxd8!, and now if 32...Qxe5, then 33. Rxf8+ Bg8 34. Rxe5; if 32...Rxd8 then 33. Qxc7; and if 32...Qxd8, then 33. Qxg7#.

  OBIT: Well, I see the game continuation is not much help with the lines that were bugging me. It looks like a good deal of home analysis will be needed to resolve this one.

  OBIT: OK, my first problem tonight was not setting up the board correctly. Having a bishop on c3 helps a lot after 30. g6 Qc7, since now 31. Qh5 h6 can be met by 32. Qxh6+ and mate next move. That leaves only 30...Qg8
Jun-18-10  Suji: <dzechiel> In your line, what if Black responds 32. ... Rbd6?

I personally like White better after <any> 32nd move by black.

  OBIT: OK, after 30. g6 Qg8 31. Rxb6 Bxb6 32. Qh5 with too many threats: (a) Re7 (b) Ne5 (c) Ng5. For example, 32...Bd8 33. Ne5 Be6 34. gh Qxh7 35. Ng6+ Kg8 36. Qxh7+ Kxh7 37. Nxf8+ followed by Nxe6 wins the house.

  Once: It's the curse that I bear. Most look at this and see a chess puzzle. I see the plot of Goldfinger. But some folk seem to enjoy these whimsies, so here we go again. Cue Shirley Bassey and Sean Connery at the peak of their powers...

How do we attack a well-defended position? We keep making threat after threat, forcing our opponent to twist and turn to defend himself, until we finally make a threat that cannot be defended.

Bond first inconveniences Goldfinger by catching him cheating at gin rummy with a combination of a blonde in a bikini, a pair of binoculars and a radio cum hearing aid. As you do. Goldfinger retaliates by covering the girl in gold paint to kill her. You have to admit that's it's a rather fiddly form of assassination. I can just imaging Oddjob spending absolutely ages with a pot of paint and a brush. Stop wriggling, girl, I've missed a bit. And it would have been a darn sight more effective (although a much shorter film) if he had gilded Bond instead...

Our version of this scene is to launch a pin prick attack on the black queen with 30. g6. Of course, the queen can't go too far from the g7 pawn cos otherwise it's Qxg7#.

Now Fritzie says that black's best is 30...Qg8 but that just looks too passive for words. Instead let's oddjob that annoying pawn with 30...hxg6.

Time to pile on the pressure. Next we catch Goldfinger cheating at golf. Bond responds with a spot of cheating himself and wins the bet. Oddjob crushes a golf ball in his fingers and decapitates a statue with a bowler hat. Nasty.

31. Rxd8 is an important zwishenzug to pile on yet more pressure. White wants to play Ng5, but doing it straight away runs into stuff like Qxf2+. So first let's drag the Rf8 away from the f file. Black has to play 31...Rxd8.

The scene is set for our third threat. Now Bond unleashes the iconic Aston Martin DB5, complete with ejector seat and rotating number plates, in an attack on Goldfinger's factory lair in Pinewood ... sorry ... Switzerland.

The third chess threat is 32. Ng5. Now if the black queen goes too far away, white has the dual threats of Qxg7# and a back rank mate starting with Qd8+. A word of comfort for <dzechiel>. Fritzie prefers your 32. Qg5 here, but both moves win.

32....Qf8 - Black defends both g7 and the back rank.

Bond's final threat is a desparate throw of the dice. Just as the laserbeam is about to part him from his standard issue weapon, he blurts out "I know about operation Grand Slam". And for some reason which I have never understood, Goldfinger decides to keep him alive and even bring him along to the scene of the crime so that Bond can later foil the masterplan. Again, as you do.

33. Qe4 unleashes an attack that can't be defended against. The new threat is Qh4+, Qh7+ and (if necessary) Qh8#

And here we must part company of the film and be denied the guilty pleasures of judo in the hay with Pussy Galore...

Returning to the chess, what I find is interesting is how white used multiple attacks to push black around until black couldn't defend himself any more. In this short combination we have a diagonal mate threat, a back rank mate threat and an h file mate threat.

"Do you expect me to talk?"

"No, Mr Bond, I expect you to resign."

  OBIT: Never mind, that was Plenty O'Toole. Honest mistake... I mean the names are so darn similar.

  Once: <OBIT> The heroine in Diamonds are Forever was Tiffany Case. Goldfinger was definitely the somewhat non-PC (these days anyway) Pussy Galore.

I would be a much better chess player if my head wasn't filled with trivia like this!

  Once: <OBIT: Never mind, that was Plenty O'Toole>

Girl: My name's Plenty.

Bond (ogling her ample cleavage): of course it is.

Girl: Plenty O'Toole.

Bond: named after your father?

Honestly, who needs satire with dialogue like that?

  dzechiel: <Suji: <dzechiel> In your line, what if Black responds 32...Rbd6?>

33 Re7 still looks good to me.

Jun-18-10  Black Cat Hamlet: I fail to see any winning line, but 30. Rh6 must be strong... it makes sense to use the pin on the pawn to White's advantage
Jun-18-10  newzild: Looked at g6 but missed the follow-up.
Jun-18-10  newzild: Poor old Bednarski is getting a hammering this week. He lost a famous game to Fischer once. Wonder if that will pop up tomorrow or Sunday...

  agb2002: White is a pawn up.

Black threatens 30... Bc7, pinning the rook and 30... Rxd6, releasing some pressure.

Most white pieces already target the black castle but it would be necessary to incorporate some more forces. This suggests 30.g6:

A) 30... hxg6 31.Rxd8 Rxd8 32.Ng5

A.1) 32... Qa(b)7 33.Qe8+ Rxe8 (33... Bg8 34.Qxd8) 34.Rxe8+ Bg8 35.Bd5 and mate soon.

A.2) 32... Qd7 33.Qf4 (threatening 34.Qh4+ Kg8 35.Qh7+ Kf8 36.Qh8+ Bg8 37.Nh7+ Kf7 38.Qxg7# and 34.Qxc4) Be6 34.Qh4+ Kg8 35.Qh7+ Kf8 36.Qh8+ Ke7 (36... Bg8 37.Nh7+ Kf7 38.Qxg7#) 37.Qxg7+ Ke8 (37... Kd6 38.Rxe6+ Qxe6 (38... Kc7 39.Re7) 39.Nxe6 Kxe6 40.Qg6+ and 41.Qxb6) 38.Qxg6+ Ke7 39.Bf6+ Kd6 40.Rxe6+, etc.

A.3) 32... Qf8 33.Qe4 + - with the double threat 34.Qh4+ Kg8 35.Qh7# and 34.Qxc4.

A.4) 32... Qg8 33.Qe(f)4 + - is similar to A.4.

B) 30... Qe7 31.Qxe7 Bxe7 32.Rxb6 + - [R+P].

C) 30... Qc7 31.Rxd8 Rxd8 (31... Qxe5 32.Rxf8+ Bg8 33.Nxe5 + -) 32.Qxc7 + -.

D) 30... Qb7 31.Qh5 Bg8 (31... h6 32.Qxh6+ Kg8 33.Qh7#) 32.Rxd8 Rxd8 33.Ng5 with multiple threats: 34.Bxb7, 34.Nf7+ Bxf7 35.Qxh7#, 34.Nxh7.

E) 30... Qa7 31.Rxb6 Bxb6 (31... Qxb6 32.Qxg7#) 32.Qh5 Bg8 33.Ng5 with the double threat 34.Nf7+ Rxf7 35.gxf7 Qxf7 (35... Bxf7 36.Re8+ Bg8 37.Bd5) 36.Qxf7 Bxf7 37.Re7 and 34.Nxh7, etc.

  gofer: It looks like everything hinges on removing Bd8 from the picture and gaining control of the all important d8-h4 diagonal, We already have the main attack Qxg7#, so the black queen is stuck to g8 or somewhere on the 7th rank. With this in mind, we would also like to create a huge outpost for Nf3 by freeing up g5 and maybe open up the h file to a multitude of queen moves. What could give me all this in one move?

30 g6 ...

<(a)> 30 ... Qf5/Qf4 31 Qxg7# <(b)> 30 ... Qc7/Qa7 31 Qh5 h6 32 Qxh6 Kg8 33 Qh7# <(c)> 30 ... hxg6 31 Rxd8! Rxd8 32 Ng5! creating the mating net with 33 g3 ... 34 Qh4+ ... 35 Qh7 mating to come <(d)> 30 ... Bf6 31 Rxb6 winning <(e)> 30 ... Rxd6 31 gxf7 winning

Main Line

30 ... Qg8

I looked for ages at 31 Rxd8 Rxd8 32 gxh7... but couldn't seem to make it work. But finally noticed the queen trap was on offer!

31 Rxb6 Bxb6

32 Ng5 Rc8/Rb8 (white is threatening gxh7 winning the queen)

33 Nxh7!

Suddenly all black's worst nightmares come true. 34 Nf6 and 35 Qh5+ are coming! Game Over.

Time to check...

  gofer: <agb2002: > In your lines B) C) D) and E) I think 31 Qh5 is mate in two, so I think the key lines are 30 ... Qg8 (which few seem to have considered) and the obviously losing 30 ... hxg6 31 Rxb6 Bxb6 32 Ng5 Q move 33 Qe4/Qg3 winning.
Jun-18-10  tarek1: I tried an awful lot of moves and plans and ideas, but I found nothing that I can honestly consider a solution.

So I decided to post something and see what it turns out to be.

<30.g6 hxg6 31.Rxd8 Rxd8 32.Qg5> this move is debatable, I didn't see anything much better in this particular line. There are many ways for black to save his hanging rook.

A) <32...Rbb8> (or <32...Rdb8>) <33.Qh4+ Kg8 34.Ng5> the point : the knight joins the attack with tempo. <34...Qd7 35.Qh7+ Kf8 36.Qh8+ Bg8 37.Nh7+ Kf7 38.Qxg7#> Here also <34.Re7> is probably decisive.

B) <32...Re8 33.Qh4+ Kg8 34.Rxe8+ Qxe8 35.Qxc4+ Kf8> if Qf7 then Bd5 <36.Ng5> with a huge attack for white.

C) <32...Qf8 33.Qh4+ Kg8 34.Re7> Black can't defend g7.

Jun-18-10  scormus: <gofer, tarek1, etc ... not defined> thanks for saving my sanity. I thought it was my wife's computer had some corrupt files and she was going to expect me to fix it.

The preoccupation kind of took my mind of the puzzle, and its a good one today after an easy week so far. 30 g6 was OK to find, hoping for 30 ... hxg6. But I wondered about other alternatives for B and I wasn't sure if W could play 31 Ng5 right away or had to play Rxd8 first. OTB I think I'd have played 31 Ng5 and probably lived to regret it :(

Jun-18-10  aragorn69: What a wonderful game by Kavalek! Impressive and very creative stuff indeed.
