Kibitzer's Corner
< Earlier Kibitzing  · PAGE 2 OF 3 ·  Later Kibitzing>
Aug-29-07  TheaN: 3/3. It's going well this week.

29....Qxf1+! was the only move that jumped out in this position. 30.Kxf1 Rxc1+. 31.Ke2 loses to 31....Be1+, so he has to move to d2, 31.Kd2.

31....Rxe5+! and Black just goes on: this move is probably the key move. White doesn't have to take the Rook, to be honest. However, being very dangerous not to, he should, but this ends after 32.Qxe5 Re1+ 33.Kd3 Rxe5 34.Rxd4 and after probably 34....Bd6 white will have a hard time defending against both a passed pawn and a piece.

About any refutation of the move 31...Rxe5+. White can move his king to three places, for neither a see I quick mate, but a win close to the same as the game, so even if I miss a mate I'll consider it correct.

32.Kf2 Be1+

32.Kf3 Re3+ 33.Kg4 (Kf2? Be1+ 34 Kf1 Bxg2# or Kf4? Bd6+ 34.Kg4 Rxg2+) Rxg2+

32.Kd3 Rc3+ (Re3+?? 33.Qxe3 dxe3 34. Rxb4) 33.Kxd4 Rxg2 34.Kxe5 (hxg3 Re2) Bd6+

Aug-29-07  realbrob: Okay, 29..Qxf1+ looks cooler because it's a queen sac, and probably it looked even better for a 19th century player. Though (as many kibitzers already pointed out) what can White do after 29..Bc5 ?

Maybe OTB I would've gone for the simple 29..Qxe5, which probably was also winning for Black. This is a puzzle with more than one solution, even though the queen sac one was the most spectacular, probably.

Aug-29-07  TheaN: <realbrob: Okay, 29..Qxf1+ looks cooler because it's a queen sac, and probably it looked even better for a 19th century player. Though (as many kibitzers already pointed out) what can White do after 29..Bc5 ?>

30.Rhf4 maybe? I know it loses a pawn but I think that 29....Bc5 only loses that one pawn (with a disasterous position for white, but that's already the case at move 29, so why delay a direct material gain?). The same counts for the immediate Qxe5.

Aug-29-07  TheaN: Oh, I see now that MAJ already analyzed 29....Qxe5 with -4.28 and Bc5 with -8.10. So they do win clearly.
Aug-29-07  TheaN: Ah damn. This <31.Ke2 loses to 31....Be1+, so he has to move to d2, 31.Kd2.> should be Kf2 and Ke2. Obvious, but wrong...
Aug-29-07  TheIrateTurk: Is it me or this week are we seeing the people who normally dispense puzzle endings be on the receiving end?
Aug-29-07  TheaN: Heh, yeah: Anderssen monday and Blackburne today. Tuesday was in Anderssen's favor, however (I can't who his opponent was, though).
Aug-29-07  TheIrateTurk: Oh, I'm a putz; I thought Anderssen was the losing player on Tuesday!
Aug-29-07  willyfly: Material is even - Black's Q is en prise - I see a lot of good moves for Black but it's not so easy for me to find White's best responces to them - I don't have much time to spend on this so I'm wondering if the quote of the day is some kind of clue - that would suggest ...Bb5 but there is also
...Ba3
...Qc2
...Qxe5
...Qxf1+
...Rxe5
not exactly a list of candidates - but moves that might work together in the right combination

that's all I have time for - let's look
-----
very nice combo

Aug-29-07  Fezzik: I love it when blitz moves work in tournament games!

I'm not sure Why White continued after 32...Re1+. Was he really hoping for some impossible back-rank mate?

I thought this was easier than yesterday's puzzle, but yesterday's puzzle led to mate.

This was certainly a bit easier than the usual Wednesday puzzle, but I know better than to complain. The next few days will probably get much harder!

  twin phoenix: hello. saw the move but didn't see combo to end so not giving myself credit. what do yall think of this tho??
20.Rxh7!? idea of course is after 20.--,Kxh7 21.Q-h4+,K-g8 22.B-h6 followed by 23. BxB and 24.Q-h6 and Q-g7 mate. thought it was kinda speculative but it is a kinda interesting attempt...
Aug-29-07  zb2cr: The way I saw it is that after 31. ... Rxe5+, White should not play 32. Qxe5. But, after 32. Kf2, Be1+ wins the Queen. (Others have pointed out that 32. Kd3 and 32. Kf3 lead to the loss of the Queen from ... Rc3+ or ... Re3+).
Aug-29-07  pawnofdoom: Qxf1 was the first obvious move that popped out at me, but I had no idea what to do after Rxc1+ Kf2 or ke2. I can't believe I didn't see Re1+ and Be1+

  twin phoenix: the more i look at 20. Rxh7 the more convinced i am that it's correct. (see my previous post.) am really curious what i'm missing. please let me know if anyone can find a flaw!!

  beenthere240: <twin> After 20. Rxh7 black can play Qf5?! with the idea mate on f2 or exchanging queens and then munching the rook. (21. Rh8+ Kxh8, 22. Qh4+ Qh5 and the attack is stalled.) Perhaps the "best" is 21. Rg7+ Bxg7 21.Qxf5 Bxf5 22. fxg7 where white has only sacrified the exchange.

  beenthere240: In my above post I mean 20...Qf5 threatening mate on f1 of course.
Aug-29-07  znprdx: <beenthere240: <twin> After 20.Rxh7 black can play Qf5?!> Yes interesting Also look at Rxe5 which lets the Queen back to e8(to capture on f8) getting mighty wild...

  beenthere240: Black may also be able to take the rook after 20. Rxh7 Kxh7 21. Qh4+ Kg8, 22. Bh6 Qf5 23. Bxf8 Qh5 again blocking the mating attack.
Aug-29-07  znprdx: znprdx: <Though (as many kibitzers already pointed out) what can White do after 29..Bc5 ?> Pretty! Was this a quiet brilliancy? Um-er-ah, what happens after 30.R(a)e4 or even Qf2...is the d3 discovery a guaranteed win? Looks a bit fuzzy to me. 29...Qxe5 is down right depressing :) what a gutless continuation. Thank the stars there is Carlsen on our chess horizon...

Yeah, it is fuzzy allright. For both sides, computer analysis of the followups to Bc5 shows a maze of many twisted variations, all alike. Takes 7-8 moves look-ahead to pick the best one.

  YouRang: Wednesday: Things get a bit trickier.

Got it, though. I noticed pretty quickly that black can pick up a rook and bishop for his queen. A bad trade by itself, but if there are further tactics that can win more material, it could be the solution.

In this case, it looked like there would be further tactics. After 29...Qxf1+ 30. Kxf1 Rxc1+, white must play 31. Ke2 (31. Kf2 is met by the 31...Be1+ skewer).

Seeing what to do after 31. Ke2, was the hard part, but really, 31...Rxe5+ emerges as the only choice, setting up the winning rook skewer (either the one played, or if 32. Kd2 Rc3+ skewer).

Aug-29-07  newton296: Qxf1!!

didnt know what to do after ke2 . way out of my league.

  kevin86: I deserve an F- on this puzzle. First,I thought it was white's move and 29 Rxh7 was the winning move-I didn't even see the black queen en prise. I then noticed 29...Rxc1,but no follow-up.

In short,I would have made far inferior moves for bOTH players-so I guess I should get a DOUbLE F.

Aug-29-07  xKinGKooLx: I don't believe it! Why do I always miss easy Wednesday puzzles?! I saw the entire sequence up to 31. Ke2, but I didn't see the key move 31. ...Rxe5+! I'm giving myself the point for today anyway. :) I need to work on seeing a lot more moves ahead than I can now!
Aug-29-07  EdwardT: can anyone tell what ...d3 whould do?
