Aug-17-04  RonB52734: "Shadout Mapes" a name from the Dune Saga? OMG!? really?
Aug-18-04  Shadout Mapes: Shadout Mapes was the name of one of the native servant people (i think) on Dune when Paul first moved there with his parents. An old woman if i remember correctly. I read it a few years back, and I liked the name Shadout Mapes a lot, so I use it as a moniker online.
Aug-18-04  iron maiden: "Without a stillsuit you would fry
On the sands so hot and dry
In a world called Arrakis.

It is a land that's rich in spice
The sandriders and the "mice"
That they call the "Muad'Dib".

He is the Kwizatz Haderach.
He is born of Caladan
And will take the Gom Jabbar.

He has the power to foresee
Or to look into the past
He is the ruler of the stars."

Jul-21-15  dfcx: White wins a knight with
34.Rxg6+ hxg6 35.Qxg6+ Kh8 (Kf8?? Qxf7#) 36.Qxd3
Jul-21-15  nalinw: First!!!

It seems a straightforward win - after all it IS Tuesday

34. Rxg6+ hxg6
(anything else ends in Rg8++)
35. Qxg6+ any

and 36. Qxd3

I spent a lot of time looking for forced mates but couldn't find one.

Jul-21-15  lost in space: 34. Rxg6+ hxg6 35. Qxg6+
Black can play 35...Kh8 and Bg7. After 35...Kf8 there is 36. Qf7#

36. Qxd3. Piece and pawn up; should be an easy win.

Jul-21-15  CHESSTTCAMPS: White has a light-squared bishop for a knight and strong pressure on g6, with the f-pawn pinned. The exchange sacrifice is easy to find, but what is the best way for white follow up?

34.Rxg6+ hxg6 (Kh8|f8 35.Rg8#) 35.Qxg6+ and now:

A) 35... Kf8 36.Qxf7#

B) 35... Bg7 36.Qxf7+ Kh7 (Kh8 37.Qg8#) 37.Qf5!+ Kh8 (Kh6 38.Qxd3) 38.Qh5+ Bh6 39.Qxh6#.

C) 35... Kh8 36.Qxd3 is winning (+B&P). An over-finesse would be 36.Qh5+ Kg7 37.Qxf7+ Kh6 and the king avoids a mating net.

Time for review....

  Oxspawn: Over the board of course I would play
34. Rc8…. Because that is the kind of player I am but I cannot make it go anywhere after 34…. Kg7

However, insomnia strikes so I am up at 5am… and the pricking behind my eyes encourages me to think of pins:

<34. Rxg6+> Looks aggressive. Is this how a world champion moves?

<34............... hxg6> on the grounds that anything else would be disaster. (34. Kh8 35. Qd8+ with only a sacrificial queen move delaying mate. 34. Kf8 35. Bc5+ winning the queen for the bishop and surely closing in on a queen and rook mate).

<35. Qxg6+> because I can; the f7 pawn being pinned…..

<35……………Kh8> (if 35…. Kf8 then 36. Qxf7#)

Now to be honest I got stuck. I wanted to continue with 36. Qf7 threatening Qg8# but could not see a way to prevent black playing Rxh3+ with the potential for everlasting check with the queen, or simply swapping rook for bishop. Playing without moving the pieces I did not ‘see’ that white could now take the rook. This is not the only difference between me and Anand, just a modest example of one of the differences.

If Anand and I had been playing as a duo in this game (Graf supported by his talented cousin Steffi) I have no doubt that between us we would have muddled through. Me and Anand. On a Tuesday. “Take the pawn, Vishy.” “With the Rook, Oxspawn?” “I would say so, Vishy.”

Steffi interjects: “Hit him with your backhand, Alex."

Time to go back to bed.

  agb2002: White has the bishop pair for a bishop and a knight.

The knight is attacked twice and defended only once because the pawn on f7 is pinned and the black rook is defenseless. These details lead to consider 34.Rxg6+ and 34.Bxf7+.

In the case of 34.Rxg6+ hxg6 (else 35.Rg8#) 35.Qxg6+ Kh8 (35... Kf8 36.Qxf7#)

A) 36.Qxd3 + - [B+P].

B) 36.Qh5+ Kg7 (36... Kg8 37.Qxf7+ Kh8 38.Qg8#) 37.Qxf7+ Kh6 38.Qe6+ Kg7 only seems to achieve perpetual.

C) 36.Bxf7 Rxh3+ 37.gxh3 (37.Bh2 Qe1#) 37... Qb7+ 38.Qg2 (38.Kh2 Be5+ - +) 38... Qxf7 39.Qxb2 Qf3+ 40.Qg2 + - [B+P] (White has the right bishop).

D) 36.Qxf7 Rxd5 (36... Qb8 37.Qh5+ Kg7 38.Qg5+ wins the rook or delivers mate) 37.Qxd5 + - [2P] is not as good as A.

-----

In the case of 34.Bxf7+ Kxf7 (else 35.Bxg6 looks crushing, for example, 34... Kg7 35.Bxg6 hxg6 (35... Rxh3+ only loses more material) 36.Qxg6+ and mate soon) 35.Qf5+ followed by 36.Qxd3 + - [R+P vs N].

-----

I think I'd play 34.Rxg6+.

Jul-21-15  diagonalley: given it's tuesday, i was "blinded" by the search for a mating sequence...DOH!
Jul-21-15  morfishine: I prefer <34.Rxg6+> 34...hxg6 35.Qxg6+ Kh8 36.Qxd3. 34.Bxf7+ wins too

*****

Jul-21-15  jith1207: <Diagonalley> Same here, My week could not have started worse, even though I identified both sequences yesterday and today, I was careless as it was the start of the week to miss key moves and probably would have ended losing or drawing or fighting to win if played OTB like that. At least from tomorrow onwards, I would not have the luxury of thinking that the puzzle would have an easier solution. Let me see if that helps.

  Once: This is one of those "ring bell for janitor" positions.

Life occasionally gives us things that simply cry out to be tried. Buttons that have to be pressed. Jokes that have to be told. I am of that generation of Englishman who cannot hear the word "infamy" without wanting to launch into "infamy, infamy, they have all got it in-for-me..."

https://www.youtube.com/watch?v=kvs...

Or who could hear half of the dead parrot sketch without having to finish it? This parrot has ceased to be ...

https://www.youtube.com/watch?v=4vu...

Today we have a pin on f7 which cries out for a repeater on g6. We simply have to look at 34. Rxg6 hxg6 35. Qxg6+

Well, that was fun. Now what? Oh, yes, we can pick up the loose rook on d3.

It doesn't always work. Heck, it doesn't usually work. But we should always look at what happens when we press the button marked "do not press".

Or put it another way. James Bond's DB5 has a red button under the gear knob which activates an ejector seat.

You'd simply have to, wouldn't you?

Jul-21-15  patzer2: Here's my look at the game and the Tuesday puzzle (34. ?) with the chessgames.com Opening Explorer (OE) and Deep Fritz 14:

<1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Nbd7 5. cxd5 exd5 6. Bf4 c6 7. h3 Nb6> The most popular move is 7... Be7 = as in
D Svetushkin vs A Leniart, 2009.

Another strong alternative is 7... Ne4 = as in Xiu Deshun vs S Shankland, 2013.

<8. Qc2 g6 9. e3 Bf5 10. Qb3> Perhaps 10. Qb3 was a novelty as it's the only game with this move in the OE.

<10...Bg7 11. Be2 O-O 12. O-O Re8 13. Ne5 a5 14. Rfc1 a4 15. Qd1 Nfd7 16. Nd3 Nc4 17. Nxa4 b5 18. Nc3 Bxd3 19. Qxd3!>

Not 19. Bxd3? when play might continue 19...Nxb2 20. Qe2 Nxd3 21. Qxd3 Bf8 22. a4 b4 23. Ne2 c5 24. dxc5 Nxc5 25. Qd1 g5 26. Bg3 Ne4 27. a5 Bg7 28. Ra2 Nc3 29. Nxc3 Bxc3 .

<19... Nxb2 20. Qb1 Nc4 21. a4! bxa4 22. Rxa4!> Here Fritz prefers 22. Bxc4 when after 22...dxc4 23. Rxa4 c5 24. Rxc4 cxd4 25. exd4 Nf6 26. Qb7 Rc8 27. Rxc8 Qxc8 28. Qb5 Qe6 29. d5 Qf5 30. Qa4 Rc8 31. d6 g5 32. Be3 h6 33. Qb5 Qe6 34. Qd3 Qb3 35. Qd2 Bf8 36. Bd4 Nd7 37. h4 Qb8 38. hxg5 Qxd6 39. Rd1 Re8 40. gxh6 Bxh6 41. Qd3 Qe6 White is a pawn up but the position is difficult and there's no clear win in sight.

<22... Rxa4 23. Nxa4 g5 24. Bh2 Nxe3 25. fxe3 Rxe3 26. Bf3 Bxd4 27. Kh1 Qa5 28. Nb2 Qb4>

Not 28... Rb3? 29. Qf5 Qd8 30. Nd3 .

Worthy of consideration is the Fritz suggestion 28... Qd2 when play might continue 29. Bg1 Rb3 30. Rc2 Qf4 31. Bxd4 Qxd4 32. Qc1 h6 33. Rd2 Qc5 34. Rc2 Qa3 35. Rf2 Nf6 36. Qd2 Kg7 =.

<29. Bg1 Rb3?> This is a mistake which allows White a strong and lasting advantage.

Instead, Black can keep it roughly level with 29... Rxf3 30. gxf3 Qxb2 31. Qxb2 Bxb2 32. Rxc6 when play might continue 32...Be5 33. Ra6 Kg7 =.

<30. Qf5!> Now white is firmly in control.

<30...Bxb2 31. Rxc6 Ne5?> This loses immediately.

Though it favors White, Black's only chance to fight for the draw is 31... Qf4 32. Qxd5 Rxf3 33. Qxf3 Qxf3 34. gxf3 .

<32. Qxg5+ Ng6 33. Bxd5! Rd3 34. Rxg6+!> This solves our Tuesday puzzle. However, White has two winning alternatives:

The first alternative win is 34. Bxf7+! when play might continue 34...Kxf7 35. Qf5+ Kg7 36. Qxd3 .

The second alternative win is 34. Rb6! when play might continue 34...Qxb6 35. Bxb6 Rd1+ 36. Bg1 Bd4 37. Qg4 Rxg1+ 38. Kh2 Bb6 39. Qb4 Be3 40. Qc3 Rd1 41. Bxf7+ Kxf7 42. Qb3+ Kf6 43. Qxd1 .

<34... hxg6 35. Qxg6+ Kh8 36. Qxd3 1-0> .

Jul-21-15  Nick46: Tricky for a Tuesday but I managed the home run, with the help of my wooden friends.
Jul-21-15  wooden nickel: <Once: This is one of those "ring bell for janitor" positions.> ...I'd certain ring the bell for one of your posts, they're amusing! <patzer2: The first alternative win is 34. Bxf7+! when play might continue ... The second alternative win is 34. Rb6!> Nice alternatives!
Jul-21-15  mel gibson: 34 Bxf7+

also wins the Rook & wins too.

Jul-21-15  zb2cr: White wins material with 34. ♖xg6+, hxg6; 35. ♕xg6+, ♔h8 (35. ... ♔f8??; 36. ♕xf7#); 36. ♕xd3 and White is up by ♗+♙.

  whiteshark: <34.Rxg6+!> should have end the game.

  Penguincw: This is a puzzle I might've gotten OTB, but not in my mind.

I saw 34.Rxg6+ hxg6 35.Qxg6+ Kh8, but I didn't see the rook being attacked, so thought 36.Qh5+? Kg8?? 37.Qxf7+ Kh8 38.Qg8# 1-0. :|

Jul-21-15  rozzatu: 34 Bxf7+ seems to win. Is it true?

  kevin86: The pins that hold the knight in place had been reduced to one by a pin. White sacs the rook for the knight and regains it with a fork,while keeping the extra bishop.

34. Bxf7+ Kxf7 35. Qf5+ Kg7 36. Qxd3

White wins the exchange plus a pawn. That ought to be enough to win, although not quite as cleanly as the game continuation which nets a piece and a pawn.

Jul-21-15  starry2013: Well this looked a mating attack so reasonable to assume that it was. I actually saw it except the Qxd3 at the end as I was looking at the king.
