Dec-21-05  Autoreparaturwerkbau: 25.Bb8! Such a great move - black can't take bishop with rook due to 26.Qxa7.
Premium Chessgames Member
  patzer2: The obstruction 25. Bb8! traps the Black Rook and wins decisive material.

  lost in space: Haven't got it. today. Though longer about Bxg5 and Qxc6 and how to make Rb7+ work. But nothing worked out.

Time to see the solution

Oct-14-10  AGOJ: Hmm. I had 25.Qb7+ first, to be followed by Bb8. I wonder if the end result is the same?
Oct-14-10  rilkefan: Found this easier than usual for a Thursday. White's entire interest is on the Qside so it's natural to use that, plus the bishop has to move.
Oct-14-10  Quentinc: <AGOJ>, so did I. Sure seems that way.
Oct-14-10  CHESSTTCAMPS: Material is even, but white has control of the open b-file and a great advantage in mobility, not unlike to yesterday's puzzle position. Today I spent a few minutes on 25.Rb7+, trying to probe the weaknesses around the black king. The tendency to follow "technical routine" (such as automatically moving a rook to the 7th rank when it's possible) sometimes can make it harder to find the best move. But the fact that white's bishop is under attack finally prompted me to find the best way to use it:

25.Qb7+ Kg8/f8/g6 26.Bb8! Rxb8 27.Qxb8 Qxb8 28.Rxb8 and the a-pawn must fall, so black can resign.

Once again, we see the theme of trapping a rook.

  dzechiel: White to move (25?). Material even. "Medium."

My first thought is that I have seen this position before (or one like it). White's bishop is en prise, so we either need to deal with that threat, or make a threat of our own that is even stronger.

Been looking at this for some time and have come to two conclusions: 1) I don't think I have seen this before after all, and 2) I'm having problems finding a good key move.

For instance, a nice forcing move is

25 Rb8 Rxb8

Or else drop material.

26 Qxa7+ Kg6

Moving to f8 or g8 allows white too much freedom. For instance, 26...Kf8 27 Bd6+ Kg8 28 Qxb8, and now white can exchange queens and run the a-pawn in unmolested. Same for the queen block 26...Qe7 27 Bxb8 and white will be able to exchange queens a clean pawn to the better.

27 Bxb8 Qe1+ 28 Kh2 Qxf2

Or 28...Qxc3. I'm not seeing it tonight.

Wait..., wait..., Of course!! I've got the right idea, but the wrong piece! The key move should be...

25 Bb8!

Threatening 26 Qb7+ and 27 Qxa8. Of course if

25...Rxb8 26 Qxa7+

Followed by 27 Qxb8. I should have seen this right away, instead I spent 20 minutes chasing down the wrong path and only spotted the correct key just before giving up.

Time to check and see how this went down.

Oct-14-10  CHESSTTCAMPS: The idea of 25.Bb8 first did not occur to me, but fortunately the transposition makes no difference.
Oct-14-10  M.Hassan: "Medium" materials even
White to play 25.?
Obviously, Black will not take the Rook with the Queen 25..........Rxb8
26.Qxa7+ Qe7
27.Qxe7 Kxe7
White saves the attacked Bishop, wins the exchange by a pawn and has a free pawn on the a file. White should win. Let's check
b8 was the square!, my line starts with the wrong piece!!!!!

  al wazir: I got it, but I'm about 99% sure I wouldn't have if it hadn't been a <CG> problem. The redoubtable <dzechiel> spent 20 minutes finding the right move. But how much time would he or I have spent on this position in an actual game? For that matter, I would like to know how much time Campora spent on it. He may have been thinking about this combination as early as move 23.
Premium Chessgames Member
  White Star: found Rb8 quite soon, which won a pawn, but forgot my own rule about looking at alternative pieces to do the same job; turns out Bb8! is the move
Oct-14-10  AGOJ: Looking at the whole game, Campora was telegraphing for some time that he was aiming at the square a6. I wonder why Cifuentes allowed it. Why not 22...a5?
Oct-14-10  TheBish: Campora vs R Cifuentes-Parada, 2004

White to play (25.?) "Medium"

I didn't find this one too hard.

25. Qb7+ Kg8 26. Bb8!

Black's rook is trapped, and he must surrender the exchange.

26...Rxb8 27. Qxb8

It's just a matter of time, and White's advantage will prove winning.

Oct-14-10  TheBish: I didn't even consider Bb8 first (patzer sees a check, etc.), but it doesn't matter as they are both about the same. (If Black had a way to weasel out, I would have looked at 25. Bb8 eventually.)

It will be interesting to see how many say they found 25. Bb8(!) when 25. Qb7+ first is much more obvious.

  Once: Let's return to our theme of "rooks can't dance". Here is the position a handful of moves before the puzzle. Black has just played 22...h5

click for larger view

The position looks reasonably level with both material and pawn structure being equal. White's rook has an open file, but he has nothing to attack along it. White has a better bishop, but this is about to be negated by black's kingside pawn roller. If neither side does anything fancy, this could fizzle out like a firework in the rain.

23. Qa6 A clever move. White grabs space and attacks both a7 and c6. This ties the black queen and rook down to the defence of pawns, which is menial labour for such powerful pieces.

White is also trying to win one of the hidden games within a game - good rook vs bad rook. At the moment, his rook on e1 is better than black's rook on a8 because it has greater mobility. White wants to make his rook even better ... and black's even worse.

23...g5 Black continues with his plan of pushing kingside pawns.

24. Rb1! The white rook finds a better open file and with gain of time. The immediate threat is of course Rb7, pinning and winning the black queen. The b file is better than the e file because white has a point of penetration - the b7 square.

Now compare the two rooks. The black rook is tied down on its home square to the defence of a pawn "staring at a pawn's bottom" - the white rook has the freedom of the board and a lovely seventh rank entry square. All rooks may be born equal, but some are more equal than others.

24...Qe8 Faced with a difficult defence, black goes wrong. Better would have been 24...Qc8 or 24...Kg6.

25. Bb8 Embarrassing the rook still further. It is going to die soon, and can only choose which diagonal is going to kill it. 25...Rxb8 26. Qxa7+ kills the rook on the a7-b8 diagonal. Or black could wibble for a move, in which case white plays Qb7 and the rook dies on the b7-a8 diagonal.

In the game black tried to counterattack the white rook but soon ran out of diagonals.

Good puzzle.

Oct-14-10  Whitehat1963: Missed it. Kept trying to make something out of 25. Rb7+.
Premium Chessgames Member
  gofer: Well, what about a rook trap?

25 Qb7+ ...

25 ... Kg6
26 Bb8! ...

Black has to accept the exchange or lose a rook for nothing!

26 ... Rxb8
27 Qxb8 Qxb8
28 Rxb8 winning

White is a RvB exchange up and Pa7 is lost too. Game over!

Oct-14-10  David2009: Campora vs R Cifuentes-Parada, 2004

White appears to win a Pawn and the exchange starting 25.Bb8. The move is safe since 25...Rxb8 is met by 25 Qxa7+, manwhile White threatens Qb7 etc. I cannot find a good defence. False trails include various losing Bishop sacrifices e.g 25 Bxg5? and the immediate Rook check which leads nowhere.

(Campora vs R Cifuentes-Parada, 2004) Crafty End Game Trainer link to the puzzle position above:

Crafty EGT follows the game line limiting losses to an exchange with 27.Rc1 (Cifuentes-Parada resigned here) Rxb8 28.Qxb8 a6.

  agb2002: The material is even.

Black threatens 25... gxf4.

The black rook is defenseless after 25.Bb8, attempting 26.Qb7:

A) 25... Rxb8 26.Qxa7+ Kg6 27.Qxb8 + - [R+P vs B].

B) 25... Kg6 26.Qb7 and Black will lose the exchange and the a-pawn.

C) 25... Qf7 26.Rb7, winning.

D) 25... Qxb8 26.Rxb8 Rxb8 27.Qxa7+ + - [Q+P vs B].

Oct-14-10  EXIDE: What a clever move ! Did not see this at all. The rook is trapped. Spent a lot of time considering other moves, unless one is familiar with this theme , the puzzle is impossible.
Oct-14-10  Metameryk: I spent like one minute on attacking possibilities before realising that White pieces are way too far to get the King. But 25. Qb8+ adds one more b8 protector and allows 26. Bb8, surrounding the Rook. It turns out that immediate Bb8 was fine too, but once I found one solution I gave up looking for a fork after 25...Rxb8.
Oct-14-10  WickedPawn: As <gofer> mentions, doesn't 25. Qb7+ (followed by 26. Bb8) lead to the same outcome?
Oct-14-10  Stormbringer: Didn't get it. Really cute move. Very impressed. :D

Happy that Kramnik drew a couple of games because when he was winning the rabid fanboys (both for and against) were all going psycho. :D

Though I have to admit I would love him to win a few more and give them all aneurysms. Guess that makes me a bad person. :-/

Oct-14-10  JohnBoy: I agree with <AGOJ> that black blundered big time with 22...h5. But white was hardly telegraphing his intentions on a6 for much of the game. Just with 22.Qd3.
