Aug-21-09  Athamas: Qa3 loses to Na5

Looks cute to take a pawn with your knight on c5 but then the black rook takes you for a ride

Aug-21-09  latebishop: I actually got this one through to 27.Bd2 after a lot of thought on a long journey home from work! I reasoned that White will at least regain the piece with a strong attack.
Aug-21-09  Athamas: Well I suppose that's not much of an explanation so I'll give a possible line.

24. Qa3 Na5

Now black is threatening to undermine your 2 exceptionally strong pawns, including 1 that is passed.

25. Rc1 is forced otherwise black's queen can jump on a4 and win the 2 pawns if you move your queen back to defend.

I think you can see how your pieces moved from extremely active in the center of the board to passively defending on the queen side.

Moves like Bd4 are coming for black and eventually push b5 to undermine white's only remaining strength.

Aug-21-09  RandomVisitor: After <23.Rxe8+> Qxe8 24.Ne6 there is:

[1.59] d=20 24...Nd6 25.Bf4 Nf7

[1.77] d=19 24...Qd7 25.Nxg7 Kxg7

Aug-21-09  dhotts: Wow, I thought the simple straight forward answer was 24.Qa3! winning the bishop at a6. It looked much better than the subtle 24.Nc7 which leads to a slim advantage.
Aug-21-09  obender71: This is what I saw:

24. Nc7 Rxe1+
25. Qxe1 Qxc7
26. Qe8+ Kg7
27. Be7 with the idea of Qf8#

Trying to free some space with 27 ... g5 fail due to 28. Bf8+ Kf6 29. Qe6 #

Instead 27 ... Kh6 is replied by 28. h4 Qe5 29. Bg5+ Kh5 30. Qxe5 Bxe5 31. Be2#

So the strongest seems 27 ... h6

27 ... h6
28. g4

And here both Qf4, Qe5, Nd6 are insufficient to hold.

28 ... Qf4 leave the 7th rank undefended
29. Bf8+ Kh7
30. Qf7+ Bg7
31. Qxg7#

28 ... Qe5
29. gxf5 gxf5
30. Qf8+ Kh7
31. Bxf5+

28 ... Nd6
29. Qf8+ Kh7
30. Bxd6 Qg7
31. gxf5 Qxf8
32. Bxf8 and here hanging black pawns on kingside and the white passed pawn on d file put Black in a unbearable position.

Others Black 28th moves?

I see only weak replies.

Ok, time to check.

Aug-21-09  obender71: Holy s..t! 27 ... h5!
Pity, it was a nice puzzle.
Aug-21-09  jsheedy: After about 5 minutes I saw this line, which I haven't fully analyzed: 24. Bxf5, gxf5, 25. Bh6, Re7, 26. Qg5+, Bg7, 27. Bxg7, Rxg7, 28. Nxg7, Qxg7, 29. Re8+, Kf7, 30. Re7+ and mate next move. Time to check...
Aug-21-09  RobertLangdon: Ooops,I tried everything....except Nc7.
Aug-21-09  5hrsolver: I spent some time looking at 27.Be7 before giving it up for the much stronger 27.Bd2 which at least wins the dark squared bishop. I think this is the key move in the puzzle.

The kingside attack coupled with the advance of the passed pawn should win for white. I must add that whites way of winning is indeed very nice.

<obender71 27 ... h5!
Pity, it was a nice puzzle.>

I went through all that too before giving it up for 27.Bd2. It is hard to give up an analysis that almost works.

Aug-21-09  PinnedPiece: This is why I love chess. 27.Nc7!

Lucky move? <I don't think so!>

Aug-21-09  mworld: wow....i saw this one thru in seconds...which usually means i luckily missed analyzing a potential threat.
Aug-21-09  YouRang: Well, I got the front-end of the idea (up through 26...Kg7), but the follow-up didn't go quite as I had imagined it would. (My imagination starts playing tricks on me when my board vision gets fuzzy.)

But I was actually a bit proud of myself. I had looked at moving the knight 2 or 3 times earlier, and each time I talked myself out of it. But on the last try, I carried the idea deeper and noticed that it opened the door for a promising queen invasion.

Beliavsky vs Gulko, 1990

White to move, (24. '?').

First of all, you should probably read all of the other posts, (I have!); it seems to me to be a waste of time to (continuously) repeat what has already been stated.

I spent over an hour on this one last night, (blowing up the diagram, and printing it out, then setting up the position on my set).

I won't write down everything I thought about. (It would take a lot of time and bore you to death, I am sure.) Instead, I will just briefly summarize.

White is clearly better, pieces on great squares, a protected passed pawn. However, how to make progress?

At first, I looked at 24.BxP/f5, gxf5; 25.Bh6. Howver, this goes nowehere, (if Black plays correctly, 24...Bf6). I looked at many other false tries as well, and eventually settled for 24.h4, trying to degrade Black's castled position (with h5, and hxg6, etc.)

I did look at 24.Nc7, but I ran up against a brick wall here. 24...RxR/e1+; 25.Qxe1, h6; as <anatoly21> and <Jimfromprovidence> pointed out. I also got as far as the game continuation 27...Qd8. Then I thought White would exchange Queens, win the Black Bishop on a8. Then what? (I totally underestimated Qf4+, not seeing the mating web that the BK was in.)

Anyway, I blew it. Not even close. This would have made a good Sunday puzzle, IMO.

Aug-21-09  penguin496: I like 24. h4

That was my thought, also. This was a very deep combination.

  johnlspouge: Friday (Difficult):

Beliavsky vs Gulko, 1990 (24.?)

White to play and win.

Material: Even. The Black Kg8 has 1 legal move, along the diagonal to f7. The White Re1 x-rays Re8 through the White Ne6, raising possibilities of a discovered attack. The Ne6 also can fork the loose Ba6 and Re8 from c7, thereby burdening the Black Qd7. The White battery Qc1 and Bg5 already have a strong grip on the dark squares around Kg8, but to threaten Kg8, White must spread his attack to light squares. The Qc1 also seems to embarrass the loose Ba6 with Qc1-a3. The White Kg1 is secured from check but vulnerable to back-rank mate.

Candidates (24.): Qa3, Bxf5

[24.Qa3 Na5, threatening 25…Bxc5. The Re1 also pins Ne6 to a mate threat at e8.]

I went for 24.Bxf5 gxf5 25.Bh6, but missed <25...Bf6>, as described by <Life Master AJ>. I also missed the dual burden of Qd7, namely, defense of Re8.

Aug-21-09  Helios727: Beliavsky socks it to his ex-comrade.
Aug-21-09  David2009: Friday's puzzle Beliavsky vs Gulko, 1990 White to play 24? Difficult

I have spent over half an hour on this. My best effort: 24 Bxf5 gxf5 25 Bh6 Nd6 26 Qg5+ Kf7 27 Qh5+ Kg8 28 Re3 and I cannot see a good defense for Black: perhaps 28 ...Rxe6 giving back material is necessary. Meanwhile I have perpetual check if on arrival at the position I can spot a good counter to 28 Re3 (this assumes, of course, that 25 ...Nd6 is Black's best reply]. Time to check.
=======
Wrong again. Interestingly, Nc7 (the first move I considered) was right after all, I saw the first three moves of this forcing line but missed 27 Bd2 and thought White simply ran out of attacking ideas.

Time to study the game continuation and also to read the refutation of 24 Bxf5 from other kibitzers (and/or playing it out over the board).

The above may be of interest to those seeking help.

Aug-21-09  YouRang: It is kinda cool how this devastating king attack hinged on what might appear to be a just little weakness on the other side of the board.

Black's bishop on a6 is hemmed in, and can't escape the knight attack by simply moving. Hence the need for the black queen to take the knight, which springs Qe8+, etc...

Aug-21-09  Anatoly21: So I took a little break from my law school job to take another crack at the problems I set myself by suggesting Blacks 25...h6 (even OTB, I couldn't see myself playing Black's 25...Qxc7. It just seems to be asking for it).

I think the best variations for both sides ends up being:

26.Bf4 g5 27.Be5 Qe7 28.Bc3 Qxe1+ 29.Bxe1 Bxc4! (getting at least a pawn for the bishop) 30.Bxc4 Nd6

Now White has either Bb3 or Bd3

31.Bb3 Kf7 32.Ne6 Bb2

31.Bd3 Kf7 32.Ne6 Bb2

The endgame looks surprisingly drawn to me. Black has c4 and b5 up his sleeve, mobilizing the black pawns; White's d-pawn is immobile because of Black's king; and Black has no easy targets for the extra piece to focus on.

I realize I'm not the best endgame player here, so can anyone show me how White is able to pull off the win?

Aug-21-09  David2009: The ever-helpful Crafty immediately found <LIFE Master AJ>'s refutation of 24 Bxf5? gxf5 25 Bh6 Bf6 e.g. 26 Re3 Kh8. http://www.chessvideos.tv/endgame-t...

In response to the game continuation 24 Nc7! Rxe1+ 25 Qxe1 Crafty continues 25...Qxc7 (as in the game) 26 Qe8+ Kg7 27 Bd2 Nd6! 28 Bc3+ (what else?) Kh6 29 Qxh8 Qe7 30 Bd2+ (if 30 h4 Bxc4!) g5 31 h4 Qg7


click for larger view

and Black appears to be holding the ending (the c4 pawn falls).

In the above position, playing White, I could not find anything better than 32 Bxg5+ Kg6 33 Qxg7+ Kxg7 34 Bf4 Bxc4 35 Bxc4 Nxc4 36 Kf1 Kf6 37 Ke2 b5 38 Kd3 Nb2+ 39 Kc2 Na4 40 Kd3


click for larger view

... Nb2+ and we are repeating moves. Instead 40...Nb6 seems very dangerous even though White has 41 Bd6 Nxd5 42 Bxc5 Nf4+ 43 Kd4 Nxg2 44 Bxa7 Nxh4 45 Kc5


click for larger view

In this position I cannot find a way of stopping Black's h pawn.

It would be interesting to have the reaction of the stronger kibitzer's to Crafty's defence 27 ...Nd6 (and indeed to these endings).

Here's your position after 32..Kg6.

There is no obligation for white to continue with 33 Qxg7+. Instead, attacking the knight with either 33 Qd8 or Qb8 looks awful for black.
