  whiteshark: I took the draw. :(
Dec-14-08  tallinn: I had a look at Fritz suggestion 34. Qxb5+ and found its justification interesting:

Qxb5+ Bc6

Qb8+!

Black can't take the queen as mate would follow: Rxb8 Rxb8+ Kd7 Rd8#. So Qd8 is forced.

White can now secure a two pawn advantage by taking in d8, but that would not justify Qxb5 as better then e5. Qe5! threats Bxd8 and Qh8+: Qe5 Qd6 Qh8+ Kd7 Qh3+ e6 (Ke8 Qh5+ Kd7 Rd1 )

e5!

Allows Qh7+ winning the rook on c2. Qe7 Qd3+

Dec-14-08  cyclon: Great, imaginative play by white. On 41.-Kc8 42.Rxd8+ Kxd8 43.Qf8+ or, 41.-Kc6/Kb6 42.Qf6+ decides.

  Richard Taylor: I found the main moves but I thought that
from this position:

But I saw 34. Qb5+ and if say Bc6 35. Qb8+ RxQ 35. Rxb8+ Kd7 36. Rd8 mate


click for larger view

Here if after 35. Qb8+ Kd7 36. Rb7+ wins (altho it's a bit tricky but there is no doubt of it)

And if 34. ... Qd7 35. Qe5 wins

And if 34. ... Kf8 35. Ne6+ wins

If 34. ... Rc6 35. Ne6 looks winning (35. ... Qd7?? 36. Qh5 mate!

(But 35. Qxb7 was my original idea but then then there is Rc1+!!)

But I only looked at the position for few minutes - usually these take me hours so I just play the game over...

  Richard Taylor: I don't use computers to analyse I analyse it all "in my head" so to speak.

This is more realistic than using computers and one learns more from it.

Of course I make errors but that is how it would go OTB

  Richard Taylor: But this was a fantastic game by both players me whatever the variations involved! Tseschkovky's play was very imaginative and that was a great combination by Aleksandr Poluljahov.
Dec-14-08  piever: I could only find the first four moves... After 33 Qf5+ Ke8 (any other king moves loses quickly) I tried to see what white could do, but after 34 Qxb5+ Bc6 I failed to visualize that 35. Qb8+! is winning and looking only at the diagram of the starting position is very difficult to see the excellent 34. e5 (at least, too difficult for me).
Dec-14-08  TheCap: Got it! WOW. But I thought black had some better lines than 34. ...rook c5 anyway, time to celebrate
Dec-14-08  Silverstrike: I only saw 34.Qxb5+ Kf8 35.Ne6+
Dec-14-08  Marmot PFL: The first few moves are easy as the white queen and the f2 sq are both attacked so white must get there first. Rxd4+ Qxd4 (forced) Qe6+ is at least perpetual so white can think for quite a while at this stage. e5-e6 is a natural attacking idea and discovers attack on Rc2. Black has a better defence in 34...Rc6 which I could not refute (computer easily finds 35.Qf7+ Kd7 36.e6+ Kd6 37.Qh5! and Rd1 winning). At this stage (34...Rc5) the tactics seem fairly simple (for a GM) with blacks king so exposed. The big challenge is working up the coursge to play 23.Bxf7+! to begin with.

  johnlspouge: Sunday (Insane):

A Poluljahov vs Tseshkovsky, 1996 (30.?)

White to play and win.

Material: N for B. The Black Kd7 is caught in the center and has 2 legal moves. The White pieces are all active, except possibly Rb1. The White Rd1 pins Bd4 to Kd7. The Black Bb7 and Rc2 are loose. The Black Rc2, Bd4, and Qf3 have a focused attack on Pf7, making Kg1 insecure. The White Kg1 is vulnerable to back-rank mates. The position calls for pushing the Black Kd7 around, to take advantage its insecure position and the loose Black pieces.

Candidates (30.): Rxd4+

30.Rxd4+ Qxd4

[else, after 30Kc6 31.Qe6+, drop a B without complications]

31.Qe6+ Ke8 32.Qxg6+ Kd7 [Kf8 33.Qf7#]

33.Qf5+ Ke8 [e6 34.Qxe6#]

The mating pattern after e6 prevents e6 later, as well.

34.Qxb5+

(1) 34Kf8 35.Ne6+ then 36.Nxd4

(2) 34Qd7 35.Qxd7+ Kxd7 36.Rxb7+

White gains a tempo to protect Kg1 from Rc1# and emerges with B+N+2Ps for R.

(3) 34Bc6 35.Qb8+

(3.1) 35Rxb8 36.Rxb8+ Kd7 37.Rd8#

(3.2) 35Kd7 36.Qc7+ Ke8 37.Rb8+ Rxb8 38.Qxb8+ Kd7 39.Qd8#

(3.3) 35Qd8 (planning a trap: 36.Bxd8 Rxb8 37.Rxb8 Rc1#)

36.Qxd8+ Rxd8 37.Bxd8 Kxd8

White emerges 2Ps up and should win.

Dec-14-08  MaczynskiPratten: A couple of thoughts on this complex position.

Firstly, I thought Black could play 34..Qd5, hitting g2, rather than Rc5. But on a closer look, 35 Qg6+ Kd7 36 e6+ Kd6 37 Nf7+ seems to win by forcing the King on to the c file so White can play Qxc2 with check.

Secondly, Black's final 40..Rd8 seems like a blunder. He resigns after 41 Qxf7+ because of Kc8 42 Rxd8+ Kxd8 43 Qf8+ picking up the loose Rook on c5, while after 41..Kc6 42 Qf6+ will pick up the d8 Rook with check (not 42 Rd8?? Rc1+! ). But after 40..Rc6 Black still seems to be alive. I suspect that both players were a bit short of time for these last moves. It would be fascinating if clock times were available for some of these games!

  johnlspouge: The trap in Variation (3.3) has not been posted yet. The kibitzes already show that 34.Qxb5+ is better than the game variation, so the only addition from Toga II 1.3.1 is that Variation (3.3) with 36.Qxd8 instead of the stronger 36.Qe5 has a value +3.63 P. It gives up a couple of Ps, but is enough to win.

  johnlspouge: One further point I missed: Black can not refuse the initial sacrifice. Instead of

[else, after 30Kc6 31.Qe6+, drop a B without complications]

30...Kc6 31.Qd5#

  chrisowen: I had rook takes bishop and envisioned this gives Qxd4 Qe6+ Ke8 Qxg6 Kd7 Qf5 Ke8 under the assumption it was winning.

  playground player: Hey, everybody! Check out the ad on the upper right-hand margin of this kibitz column: Ray Keene is helping British police solve a real-life murder mystery. Is that cool, or what?
Dec-14-08  TomOhio: Doesn't Black do better with

34. ... Qd5 (threatening g2#)
35. f3 Qa2 (g2 again)
36. Qg6+ Kd7
37. Rd1+ Bd5
38. Rxd5+ Qxd5
39. Qxc2 Qxe5 (threatening e1#)
40. Ne4 Qa1+
41. Kf2 Qxa5

Up the exchange with unmatched passed pawns... I'd take that over resigning. This is... I'm not very good, so I know I'm missing a lot here. So, what is it???

Dec-14-08  blaibu: what was wrong with 27. ... Qxa5
Dec-14-08  karoaper: *sigh*
5 more hours.
Dec-14-08  MaczynskiPratten: <TomOhio> I think you've missed 35 Qg6+ with the sequence described 5 posts above - hence White need not play 35 f3
Dec-14-08  zooter: 30.Rxd4 is quite easy to find, but after 30...Qxd4, what's the correct follow up?

31.Qe6+ Ke8 and now what? white has to defend his f2 and g2...

hmmm....I don't see how this wen

Dec-14-08  njchess: I found the first four moves for White readily enough, but then I spent about 5 minutes before I found Qxb5+ followed by Qb8+ mate sequence. I'm not surprised that e5 was played however, since I suspect time control and the pressure of the game hanging in the balance probably caused White to miss this finishing sequence.

  Calli: I agree with <MaczynskiPratten> 40..Rd8? simply loses the rook. After 40...Bd5 which has the threat Rg8, the win is not clear to me.
