Jun-08-12  deadlyduck: I eventually found the double bishop sacrifice (reminds me of a Kasparov game from the 80's) but I spent a lot of time playing around with 22. Qh5 (initially thinking there was a devious Queen sac after ..g6; 23.Qxh7+ Kxh7;24. h5 but I couldn't see compensation after Black plays 24..f6)

However, the Qh5 move does appear to give a very strong attack for White. For example, if 22..g6; then 23.Qh6 f6; 24.h5 seems extremely unpleasant -possibly lost?- for Black. Equally, the attempts to defend with 22..h6; gxh6 and 22..f5; gxf5 Nxf6;Bxf6 Rxf6 seem bad too. However, the actual continuation in the game is neater

Jun-08-12  Zatrikion: 22.Bxh7+!

Black declines sacrifice:
a)22..Kh8, 23.Qh5 Re8 (if 23..Nf6, gxf6 and mate is near), 24.Bg6+ Kg8, 25.Qh7+ Kf8, 26.Qxg7+ Ke7, 27.Qxf7#

Black accepts:
b)22..Kxh7, 23.Qh5+ Kg8, 24.Bxg7 Kxg7 (24..f5, 25.Qg6 1-0), 25.Qh6+ Kg8, 26.g6 fxg6 (26..Nf6 27.g7 Nh7 28.hxf8Q+ Qxf8, 29.Rg1+ 1-0) 27.Qxg6+ Kh8, 28.Qh6+ Kg8, 29.Rg1+ Kf7, 30.Rg7+ Ke8, 31.Qg6+ Rf7, 32.Qxf7#

  David2009: Taimanov vs A Shashin, 1978 White 22?

IF I have the solution correct the main vartiation is longer, but more straightforward, than yesterday: 22.Bxh7+ Kxh7 23.Qh5+ Kg8 24.Bxg7 Kxg7 25.Qh6+ Kg8 26.g6 fxg6 27.Qxg6+ Kh8 28.Qh6+ Kg8 29.Rg1+ Kf7 30.Rg7+! (the hard move to spot) Ke8 31.Qg6+ Rf7 32.Qxf7#. Ten moves long but not deep. Black's main alternative is at move 24 whan f6 or f5 could be played, but White can choose OTB between 25.gxf6?! Nxa8 (which might be OK for Black), 25 Bxf6 or 25.Bc3 (if f5 was played), and the check on h8 followed by g6+ (which seems OK for Black). The point is, one checks all this at move 25. Time to see what happened:

Encouraging. Here's the puzzle position:

and a link to Crafty End Game Trainer:
http://www.chessvideos.tv/endgame-t...

The intelligent robot defends with 24...f5 25.Bc3 Bd4! (I had missed this move) 26.Bxd4 Nxd4 27.exd4 bxc4 and I decide discretion in the better part of valour: 28.Qg6+ draw by repetition. If I play 25.Bf6 then Rxf6 26.gxf6 Qxf6 27.Rg1+ Kf8 and White is very vulnerable.

Well a draw against 'Ole Crafty' (in <Morf>'s words) isn't too bad. Enjoy finding the win if there is one and feel free to post the EGT buster!

Jun-08-12  bachbeet: I saw the first move but took a different line after that so no points for me.
Jun-08-12  Babes: I'm not totally sure anyone has been able to refute 24...f5. patzer2's suggestion of 25. Qh8+ Kf7 26. g6+ Ke7 27. Qh7 looks like it can be defended by 27...Qe8, whereby something like 28. Bxf8+ Kxf8 29. Rd1 bxc4 leads to a position where Black has three pieces against a rook and three pawns with an exposed king and the three biggest threats to an exposed king (a queen and both rooks) still remain for White. Also, White has connected passed pawns on the kingside, so I think unclear is a fair assessment there.

As for agb2002's 25. gxf6, he refutes 25...Nxf6 convincingly, so 25...Rxf6 is the next logical option to explore. 26. Bxf6 Qxf6 is another one of those positions where Black will have a material advantage, but the king is exposed. Personally, I prefer patzer2's line to this because there White has the g5-pawn to push towards promotion.

David2009's 25. Bc3 is a nice idea, and if Crafty can't get more than a draw for Black, then neither can I. 25...Qe8?? 26. Qh8+ Kf7 27. Qg7# not working is a disappointment from Black's perspective.

And for anyone itching to pick on my analysis, I would like to offer up the line 25. g6 Kxg7 26. Qh7+ Kf6 27. g7. If 27...Rg8, then 28. Qh6+ Kf7 29. Rg1 and if 29...Qe8 then 30. d6!! looks like a winner to me. However, this is only one line.

P.S. I hardly considered 24...Kxg7, assuming that Black would be finished after 25. Qh6+ Kg8 26. g6, which is true, but was still very careless of me to assume.

Jun-08-12  scormus: Attractive puzzle and ending, but is 24 ... Kxg7 forced? Well no, but surely W can win prosaically after 24 ... f5. 25 Qh8+ Kf7 26 Bxf8+ Qxf8 28 Qxf8+ Kxf8 29 Rb1 is probably good enough.

It seems CG is doing a special on B-sacs on the 7th rank. And why not? Today greece played in the Euro football cup so the first move is appropriate.

The tempting variant 22. Bxg7 doesnt work, seems not quite forcing enough. After 22 ... Kxg7 23 Qf5 Re8 24 Qh7+ the BK can escape via f8 and e7.

Jun-08-12  LoveThatJoker: Cool! A Taimanov puzzle!

<22. Bxh7+ Kxh7>

(22...Kh8 23. Qh5 and White wins)

<23. Qh5+ Kg8 24. Bxg7 f5!>

[24...Kg7 25. Qh6+ Kg8 26. g6 Nf6 (26...fxg6 27. Qxg6+ Kh8 28. Qh5+ Kg7 29. Rg1+ Kf6 30. Qg6+ Ke7 31. Qe6#) 27. Ne5! Qa5+ 28. Kf1 Nd2+ 29. Ke2! and White wins because of the threat of 30. gxf7+ followed by 31. Rg1+; 24...f6? 25. g6 and Mate next move]

<25. gxf6! Nxf6>

(25...Rxf6 26. Rg1! Nxa1 27. Bxf6+ Kf8 28. Rg7! Nc2+ 29. Kd1 Nxe3+ 30. fxe3 and White will Mate Black shortly; 25...Qxf6 26. Bxf6 )

<26. Qg6 Rf7 27. Rg1!!> 1-0 White will Mate Black shortly with a most phenomenal windmill-like device. For example, 27...Ng4 (27...Ne8 28. Bf6+ Ng7 29. Bxg7 and White wins as Black can never stop this windmill) 28. Rxg4 Raa7 29. Bf6+ Rg7 30. Bxg7! and Black will eventually get Checkmated.

LTJ

Jun-08-12  LoveThatJoker: Just checked my solution with Stockfish

a) In the game continuation, 27. Ne5 is okay, but not nearly as strong as 27. Rg1 which forces mate.

b) In the 24...f5 25. gxf6! Nxf6 line, 26. Qg6 is countered with 26...Qe8. White then has 27. Qg5 which continues giving him a (+0.56) advantage (at a depth of 21), but that is nothing compared to the much more on-the-mark 26. Bxf6.

Therefore a 0.25 out of 1 for today; leaving me with a score of 4/5 thus far.

How does black get out of this mess? The king is stuck on g8 and so the discovered check is going to happen!

Jun-08-12  Memethecat: 22.Bxh7+ Kxh7 (22...Kh8 23.Qh5 & # in 2)

23.Qh5+ Kg8 24.Bxg7 Kxg7 (24...f6 25.g6 Kxg7 26.Qh7#)

25.Qh6+ Kg8 26.g6 fxg6 27.Qxg6+ Kh8 28.Qh6+ Kg8 29.Rg1+ Kf7 30.Qe6#

There are a couple of other ways the end could go but I think the general idea is right.

Jun-08-12  M.Hassan: "Difficult" White to play 22.?
White is a pawn up.

Both Bishop attacks occured to me but somehow I did not work them in the right order until I recived help form Chessmaster program:

22.Bxh7+ Kxh7
23.Qh5+ Kg8
24.Bxg7 Kxg7 (forced otherwise mate on h8)
25.Qh6+ Kg8
26.g6 Nf6
<if...fxg6 27.Qxg6+ Kg8 28.Qh6+ Kg8 29.Rg1+ Qg5 30.Rxg5+ Kf7 31.Qe6#>

27.Rg1 Qa5+
28.Nxa5 Bb4+
29.axb4 Nxh1
30.g7 Nc2+
31.Kd2 Ne4+
32.Kc1 Nxb4
33.Qh8#

  TheBish: Taimanov vs A Shashin, 1978

White to play (22.?) "Difficult", White is up a pawn.

Black may be down a pawn, but he's attacking two pieces (Ra1 and Nc4), so it looks like he's sitting pretty. But on further inspection, his king is a sitting duck, if exposed properly!

22. Bxh7+! Kxh7

Virtually forced, since 22...Kxh7 23. Qh5 Re8 24. Bxg7+! Kxg7 25. Qh6+ Kh8 26. Bg6+ Kg8 27. Qh7+ Kf8 28. Qf7 is mate.

23. Qh5+ Kg8 24. Bxg7!

The point -- White's bishops explode Black's pawn shelter like dynamite.

24...Kxg7 25. Qh6+ Kg8 26. g6 Nf6

Or 26...fxg6 27. Qxg6+ Kh8 28. Qh6+ Kg8 29. Rg1+ Kf7 30. Rg7+ Ke8 31. Qg6+ and mate next move.

27. Rg1! Qc7

To create an escape path for the king after 28. gxf7+ Kxf7 29. Rg7+ Ke8 30. Qg6+ Kd8.

28. g7 Nh7 29. gxf8#.

This final mating position looks familiar; maybe I've seen it before, but I still had to do the "ground work" to get there!

  TheBish: <Bhrugu: White could have started this combination one move in advance (move 21), correct?>

Yes, I thought the same thing as soon as I played through the game. Taimanov must have missed this earlier.

Jun-17-12  Babes: You're absolutely right, gofer. In that case, it's back to 25...Nxf6 26. Bxf6 Qxf6 27. Rg1+ Qg7 28. Rxg7+ Kxg7, but I would not envy Black in such a position.

  RookFile: Black castled into a strong attack.
Nov-29-16  paavoh: Black was being pushed around and finished off by the double B sac.

On another note, it was a surprise to see how lucid <chrisowen> was in 2012.

  Honza Cervenka: It was possible to start the combination one move earlier 21.Bxh7+! with the same outcome. If 24...f5, then 25.Qh8+ Kf7 26.g6+ Kxg6 27.Qh6+ Kf7 28.Qe6+ Kxg7 29.Rg1+ leads to mate. Of course, black is not forced to take the Pawn after 26.g6+ but after 26...Ke8 28.Bxf8 Nxf8 29.g7 or 26...Ke7 27.Qh7! he faces heavy loss of material with utterly hopeless position.

  morfishine: Nice game, too bad its polluted with yet again, another dumb, nonsensical, irrelevant game title

A real pity

*****

Nov-29-16  Sally Simpson: I'm 100% in agreement with you Morf. Some games have a pun that matches perfectly but 90% of them are awful.

I know this is your thing but have you tried simply ignoring the pun and letting it go.

  morfishine: <Sally Simpson> Yes, I am at that point. I was hoping there would be some improvement since I believe this detracts from the quality of the site <CG>. There have been suggestions to create a separate location at <CG> for true "Game of the Days" GOTD, and another location for silly puns; but this idea has not gained traction over the years for some reason.

I wonder why?

*****

Dec-02-16  Sally Simpson: Hi Morf,

Maybe a 'pun off' button like an ignore button could be a suggestion. Or get them to tamper with just your login so you cannot see them.

I don't think the pun detracts from the site, it does OK for itself (I would not sub up if I thought otherwise) my main gripe with the puns is that sometimes they get in the way and a whole load of space is wasted talking about them and saying how good they are.

Also I think that...hang on...I'm wasting space talking about a pun....OOPS!
