Feb-13-11  morfishine: Missed this beaut! Thanks <timothee3331> for covering <36...bxc6> (alternative to <36...Kxc6>)

I didn't appreciate that black could toss the g-pawn with <35...Rf7>

The line I followed was <35...Kd8>...Oh well, one mustn't miss a thing against Korchnoi

Feb-13-11  timothee3331: <morfishine> You're welcome !

Yes, Viktor the Terrible is still a wonderful player with a lovely personnality ^^ (No need to talk about 2001 !)

Please everybody, Take a look at <TuxedoKnight> chess puzzle, it's really funny and his site is interesting.

Feb-13-11  Marmot PFL: Good game by Korchnoi even if white should have drawn. Even down a queen white plays on, hoping the veteran will have a stroke maybe.
Feb-13-11  lost in space: No, not today and not even close. Hoping for Monday.
Feb-13-11  knight knight: Sunday. Ok black's 35...Qxf1# threat means we can eliminate a lot of moves, the only ones that don't lose immediately are:

35. h3, 35. h4, 35. Rxe1, 35. Rc7+, 35. Qg7+, 35. Qh7+

and I'd say the solution is white to draw by perpetual check.

Pawn moves:-

a) 35. h3 Qxf1+ 36. Kh2 Qg1+ 37. Kg3 Rxf3+:

ai) 38. Kxf3 Re3+ 39. Kg4 Qxg2+ 40. Kh5 Qxh3+ and 41...Qxh8 queen + three pawns ahead

aii) 38. Kg4 Qxg2+ 39. Kh5 Qxh3+ 40. Kg6 Qxh8 41. Rxe1 queen + three pawns ahead

b) 35. h4 Qxf1+ 36. Kh2 Qh1+ 37. Kg3 Qxh4+ 38. Qxh4 gxh4+ 39. Kxh4 Rxc1 two rooks ahead

Queen moves:-

a) 35. Qg7/h7+ Rf7 36. Rc7+ Kd6! no more decent checks

b) 35. Qh7+ Rf7 36. Qd3 Rxc1 no more perpetual and Q/Rxf1+ on the next move

c) 35. Qg7+ Rf7 36. Qxg5+ Kd7 37. Rc7+ Kxc7 no more decent checks

Rook moves:-

a) 35. Rxe1 Qxe1 36. Kg1 (if 36. Qh7+ Kd6 is now possible) Qe3+ 37. Kh1 Qf2 the bishop is lost... 38. h3/h4 Qxf1+ rook ahead, white has no perpetual

b) 35. Rc7+ Kd6:

bi) 36. Qd8+ Ke5 white's rook gets in the way... 37. Qh8+ Rf6 no more decent checks, white must play 38. h4 Rxf1+ 39. Kh2 Qxh4+ 40. Qxh4 gxh4 41. Rxb7 black is a rook ahead, or 38. h3 Rxf1+ 39. Kh2 Qg1+ 40. Kg3 R(1)xf3+ 41. Kg4 Qxg2+ 42. Kh5 Qxh3+ and 43...Qxh8 with mate very soon

bii) 36. Rd7+ Kxd7 37. Qg7/h7+ Kd6 no more decent checks

biii) 36. Rc6+!! this has to be the move, found by process of elimination, but it works as follows:

a) 36...Ke7 37. Rc7+ repeating

bi) 36...Kd7 37. Rd6+!! Kxd6 38. Qb8+ this is the position we want, will call it 'Position A' and discuss it more in a mo

bii) 36...Kd7 37. Rd6+ Kc7?? 38. Qd8#

bii) 36...Kd7 37. Rd6+ Ke7?? 38. Qd8+ Kf7 39. Rd7+ Kg6 40. Qg8+ Kf6 (40...Kh5/h6 41. Rh7#) 41. Qg7#

c) 36...Kxc6 37. Qc8+ (37. Qc3+ Kd6) Kd6 38. Qb8+ the same 'Position A'

d) 36...bxc6 37. Qb8+ this we'll call 'Position B'

Ok, in Position A we see the black king can't find refuge on the queenside, e.g. 38...Kc6 39. Qc8+ Kb6 40. Qd8+ and the king must return to c6.

Let's try the kingside, 38...Ke7 39. Qc7+ Kf8 40. Qd8+ Kg7 41. Qe7+ Rf7 42. Qxg5+ the queen checks along the d8-h4 diagonal and also the h6 square if need be. Black's rook actually gets in the way of his king here.

The other try is to escape via e5, but this fails to a skewer trick. 38... Ke7 39. Qc7+ Kf6 40. Qd8+ Ke5 41. Qc7+ Kd4?? 42. Qc5+ picking up the queen with a winning material advantage

In Position B the queenside escape is impossible, the kingside escape fails as in Position A, plus the king still cannot escape via e5... 37...Ke7 38. Qc7+ Kf6 39. Qd8+ Ke5 40. Qc7+ Kd4?? 41. Qxa7+ c5 42. Qxc5+ again picking up the queen.

I'd better be right after an hour of analysis!!

Feb-13-11  LoveThatJoker: Here is what I've come up with:

White is playing for a draw here because even if she is still looking to fight on and exchange rooks along the first rank, she'll be left with Q+B+P vs Q+R. And thusly (also taking into account the resulting position itself) it looks like the best White can get, if she is lucky, is a draw.

That being said, White has an instant draw available!

35. Rc7+!! Kd6 36. Rc6+!! bxc6

[36...Kxc6 37. Qc8+ Kb6 38. Qd8+ Kc6 39. Qc8+ Kd6 40. Qd8+ Ke5 (this is where the fun starts) 41. Qb8+! Kf6 (41...Kd4?? 42. Qxa7+ wins) 42. Qf8+ Kg6 39. Qg8+ Kh6 40. Qh8+ Kg6 41. Qg8+ Kf6 (41...Kh5?? 42. Qh7#) 42. Qf8+ and a draw will have to be agreed on at some point; 36...Kd7? 37. Qc8+ Ke7 38. Rc7+ Kf6 (38...Kd6 39. Rd7+ Ke5 40. Qb8+! Kf6 <40...Kd4 41. Qxa7+ wins> 41. Qh8+! Kg6 42. Qh7+ Kf6 43. Qg7#) 39. Qh8+ Kg6 40. Qg7+ K any 41. Qh7#]

37. Qd8+ Ke5 38. Qb8+ Kf6 (38...Kd4 39. Qxa7+ wins) 39. Qf8+ Ke5 40. Qb8+ Kf6 41. Qf8+ Kg6 42. Qg7+ Kh6 (42...Kh5?? 43. Qh7#) 43. Qh8+ Kg6 44. Qg8+ and a draw will have to be the result unless Black wishes to lose!

In this line, White would play 38. Qd8+ (only move) and not 38. Qb8+

  Phony Benoni: <EXIDE>: After <35.Rc7+ Kd6 36.Rc6+ Kxc6 37.Qc8+ Kd6>:


click for larger view

Try <38.Qd8+> instead of 38.Qb8+. After <38...Ke5 39.Qb8+ Kf6> (39...Kd4 40.Qxa7+) <40.Qf8+> and the draw is clear.

Feb-13-11  patzer2: For today's Sunday puzzle solution 35.Rc7+ Kd6 36.Rc6+!! = is an amazing drawing resource to force a draw by perpetual check that White missed in the actual game.

Here's a breakout using Fritz 10:

35.Rc7+ Kd6 36.Rc6+!! bxc6

[36... Kxc6 37. Qc8+ Kb6 38. Qd8+ Kc6 39. Qc8+ Kd6 40. Qd8+ Ke5


click for larger view

41. Qb8+! Kf6

(Not 41... Kd4?? 42. Qxa7+ )

42. Qf8+ =]

37. Qd8+ Ke5


click for larger view

38. Qb8+! Kf6 (Not 38...Kd4?? 39. Qxa7+ ) 39.Qf8+ Kg6 40. Qg8+ Kh6

(Not 40... Kh5?? 41. Qh7#)

41. Qh8+ Kg6 42. Qg8+ =.

P.S.: The threat of a winning skewer keeps the Black King from escaping to the d4 square to avoid the draw by perpetual check in both the 35.Rc7+ Kd6 36.Rc6+!! bxc6 and 36...Kxc6 variations.

Feb-13-11  VincentL: "Insane".

White is an exchange down and black threatens immediate mate with Qxf1.

Mrs Ivanchuk better do something fast.

This must start with a series of checks.

35. Rc7+ Kd6 (only move) 36. Qd8+ Ke5 (only move).

Now I don't see a continuation.

OK. Letīs start instead 35. Qg7+. Now if 35.....KD6 36. Qc7 mate. So black must play 35....Rf7. Now 36. Rc7+ Kd6.

Again, I don't see how to continue.

The only other move white has is 35. Rxe1 (surely this doesn't start h3 ?).

Again I see nothing.

Itīs time for me to go out into the desert, so I must check.

Feb-13-11  VincentL: Today itīs a question of "Easy when you see it".

Feb-13-11  buckssquares: id go for draw . instead of h4. Qg8
Feb-13-11  Patriot: Material: Black is up the exchange.

Threats: ...Qxf1#, ...Rxf1+, Rxc1

I've been looking at this for some time, examining the checks and possible responses, and I think there is only one good course for white--35.Qg7+.

Some ideas look bad. For example,

A) 35.Rc7+ Kd6 36.Qd8+ Ke5 37.Qh8+ Rf6 (37.f4+ Qxf4 38.Qh8+ Rf6 )

B) 35.Qh7+ Rf7 36.Rc7+ Kd8 (36...Kd6 ) 37.Qg8+ Kxc7 38.Qxf7+ Kb6

C) 35.Qg7+ Rf7 36.Rc7+ Kd6

The only sequence that gives white a chance seems to be:

35.Qg7+ Rf7

(Not 35...Kd8 36.Qc7+ Ke8 37.Qb8+ Kf7 (37...Kd7?? 38.Rc7+ Kd6 39.Rc2+ winning the queen) 38.Rc7+ Kf6 (38...Kg6 39.Qg8+ Kf6 40.Qh8+ Kg6 41.Qg7+ Kh5 42.Qh7#) 39.Qh8+ Kg6 40.Qg7+ Kh5 41.Qh7#). And of course not 35...Kd6 36.Qc7# or 35...Ke8 36.Rc8#.

36.Qxg5+

Anything else seems to lose. I "could" stop here.

A) 36...Kd6 and at least 37.Rxe1 Qxe1 38.Qg3+ Qxg3 39.hxg3 might give drawing chances. Also interesting here is 37.Qd8+ which might win (or lose). I would calculate this when the position is reached.

B) 36...Rf6 37.Qg7+ Rf7 =

C) 36...Kf8 37.Rc8#

D) 36...Ke8 37.Rc8+ Kd7 38.Qd8#

Now I'll have to see what happened and what key lines I missed...

Feb-13-11  stst: First sight and the kind of problem is to challenge a win for White. But intuition says no. The position is simply too imminent of losing that the White R at some time must exchange for the Black Rook at e1.

After 35 Qg7+ Rf7 (Kd6 allows a quick mate, Kd8 a slightly slower one) 36 Qxg5+ Kd7, White is running out of further threats, and Black is too strong both in material and position.

I saw the same as the While players, to settle for 37. RxR, but this doesn't do anything good for White, and would eventually lose.

The line 37.Rc7+ KxR, 38.Qg3+ QxQ, 39.PxQ RxB+, 40. Kh2 Rh7# yields a even a quicker mate.

If any engine can find a win for White, I'll consider it good one.

Feb-13-11  Patriot: Well I tried! I missed the 35.Rc7+ Kd6 36.Rc6+!! idea. Plus I missed a simple candidate (probably from looking at this too long)--35.Qg7+ Rf7 36.Qxg5+ Kd7.

I relied on the 35.Qg7+ line by the process of elimination and was willing to settle with it.

Conclusion: I missed the draw but I don't feel too unhappy about my thought process. I recall looking at the key move (36.Rc6+) but didn't think it made sense.

Very interesting puzzle!

Feb-13-11  Patriot: People complain so much about draws, and while a lot of them are dull, some can be pretty spectacular as could have happened in this game!
Feb-13-11  DarthStapler: I didn't get it
Feb-13-11  riverunner: The annotation at 35. makes no sense.
"Rc6+!!!" What is he so excited about? PxR, The king gets pushed around a bit and escapes.

  agb2002: White is an exchange down.

Black threatens 35... Qxf1#.

Apparently, the bishop can't be protected: 35.Rxe1 Qxe1 36.Kg1 Qe3+ 37.Kh1 Qf2 38.Qa1 Re5 (trying either 39... Qe1 or 39... Re1) 39.Qc1 Kd7 40.Qd1 Re1 - +.

Since the amount of pawns avoids any chances of stalemate, the only possibility left is counterattack (CRIPT: Counterattack-Run-Intercept-Protect-Take). The first move that comes to mind is 35.Qg7+:

A) 35... Kc7 36.Qc7#.

B) 35... Ke8 36.Rc8#.

C) 35... Kd8 36.Qc7+ Ke8 37.Qb8+

C.1) 37... Ke7 38.Rc7+ Kf6 (38... Kd6 39.Rc2+ and 40.Rxf2 + -) 39.Qh8+ Kg6 40.Qg7+ (or 40.Qh7+ Kf6 41.Qg7#) Kh5 41.Qh7#.

C.2) 37... Kf7 38.Rc7+ Kg6 (38... Kf6 39.Qh8+ transposes to C.1) 39.Qg8+ and mate next.

D) 35... Rf7 36.Qxg5+ (36.Rc7+ Kd6 - +)

D.1) 35... Ke8 36.Rc8+ Kd7 37.Qd8#.

D.2) 35... Kf8 36.Rc8#.

D.3) 35... Kd7 36.Rxe1 Qxe1 37.Kg1 a6 followed by pushing the d-pawn looks bad for White.

Another option is 35.Rc7+ Kd6 36.Qd8+ Ke5 37.Qh8+ Rf6 but White loses.

I don't know, but would try 35.Qg7+.

  agb2002: Very nice. A memorable position.
Feb-13-11  Magic Castle: <riverunner> After pxR, the black queen is in danger of being skewered with the capture of the a7 pawn with check when the king wanders to d4. So the King will be confined to the 5th, 6th and 7th rank and perpetual check will ensue, with the queen initiating the checks from the 7th rank. Try again with these ideas on mind.
Feb-13-11  M.Hassan: "Insane" White to play 35.?
White has a Bishop for a Rook.
I worked on this puzzle last night and continued tonight. I was making the first right move in MO and it was after the first move that it took me so long to find. This is what i did:

35.Rc7+ Kd6
36.Rc6+ (the critical move) bxc6
37.Qd8+ Ke5
38.Qb8+ Kf6 <if...Kd4 39.Qxb7+ and Black Queen is lost> 39.Qf8+ Kg6
It is a perpetual state 1/2-1/2
Time to check
------------
Miles away

Feb-13-11  Patriot: <M.Hassan> <Miles away>

Hey don't cheat yourself out of finding the solution. 35.Rc7+ Kd6 36.Rc6+!! is correct! :-)
