  Marmot PFL: Saw this idea instantly but could not work out the details well enough to say i would definitely play it. Specifically I missed the strength of 21...ef5 as opposed to Bxe4 right away.

Black to move, (20... '?').

Sunday; August 16th, 2009.

(Here was today's position to ponder.)


click for larger view

I thought today's problem was rather easy. Sometimes I spend many minutes puzzling over what the first move might be, in today's problem it was blatantly obvious that Black had to give up the Queen. The only real question remained as to what the follow-up might be. (I spent at least half an hour pondering the lines before looking at the game. I even printed out a copy of the diagram, and set the position up on my chess set.)

After 20...QxN/c3! 21.bxc3, I did look at the follow-up 21...exf5; but after 22.h4, considered things to be less clear.

Instead, I spent all my time looking at 20...Qxc3; 21.bxc3, Nxg5!; (my choice, and the FIRST choice of Fritz); I consider this a more forcing option.

For example, after 21...Nxg5; Black threatens ...BxP/e4+ (Kg1) and then ...Nh3#. I considered a lot of different moves, but finally decided on 22.Qe3, for White. (This move prevents Black from playing any variations with ...Nh3.) At first, I wanted to play ...BxP/e4+; but later decided that 22...NxP/e4 was best. (Threatens ...Ng3+; winning more material.) Now 23.Kg1 looks forced, when 23...RxP/c3; picks off another button. I looked at a few more moves, but my final assesssment was that Black would be winning. White's position would be in shambles, and in most variations Black emerges with a Rook, a Bishop, and 3-4 Pawns for the (lost) Queen. (In addition, Black still has a powerful initiative ... and lots of threats against White's King.)

OK, so much for the human brain, let's see what the silicon monster comes up with: [>/= 21...Nxg5!; 22.Qe3T, (22.Rfe1 Nxe4; 23.Rxe4 Bxe4+; 24.Kg1 Rxc3; 25.Qe1 Rc4 ) 22...Nxe4; 23.Kg1 Rxc3; 24.Qe1 Bf6; 25.Be3 Re8; 26.Rc1 exf5; 27.Rxf5 Ng5; 28.Bxg5 Rxe1+; 29.Rxe1 Bd4+; 30.Kf1 f6; 31.Bd2 Rxc2; 32.Re7 Bg2+; 33.Ke1 d5; " "]

BTW, White's 22nd move here was inaccurate, the computer's light goes off and Black's advantage nearly doubles.

Aug-16-09  LIFE Master AJ: A good week, I successfully solved all the problems. I was 100% on the key moves, and most of the time my analysis was dead on. (This is actually the FIRST time I ever correctly solved all the daily puzzles ... believe it ot not.)
Aug-16-09  tacticalmonster: 1) black queen is traped
2) black is up a piece
3) black has a terrific octupus knight on f3 if it can stay there 4) white kingside pawn is overextended
5) white king is near stalemate

conclusion: Black must give up the queen to inflict positional and material damages. Black must also take advantage of his knight, the h1-a8 diagonal to exploit the weakness of the kingside pawn and the white king

motto: Bxe4, Nxg5 and Nh3( mate or forking king and queen)

candidate: Qxc3 and Rxc3

a) 1 Qxc3 bxc3 2 Nxg5 Rae1 3 Nxe4 Rxe4 4 Bxe4+ Kg1 5 Bxf5 with great compensation for the queen

b) 1 Rxc3 Bxa5 2 Bxe4! Qg2! 3 Rxc2! ( 3 Qxc2 4 Bxc2 Rxf3 5 Be4 ) Qg3 4 Nxh2+ Kg1 5 Nxf1 Kxf1 6 Bxf5

I choose Rxc3

Aug-16-09  Athamas: The line 20...Rxc3 21. Bxa5 Bxe4 is refuted by Bxc3 not Qg2
Aug-16-09  Deji: I feel disappointed with myself so, I won't say much. I saw

1) Qxc3 bxc3
2) Bxe5 hoping for a discovered check by Nxg5+ Kg1, Nh3# and also forking queen.

  Once: A little odd that we have notes to this game by the winner, but he gives himself "!!" for the fairly obvious 20...Qxc3 and not for the rather more subtle 18...Ne5.

He did see all this before playing the trap 18...Ne5, didn't he?

Aug-16-09  kingsindian2006: Dragan Slayer ..would be my pun...hehe. Chess has beauty in the attack and defending properly under fire ...
Aug-16-09  Manoloo: The name of this game must be "Dragan Ball"
Aug-16-09  Manoloo: Maybe a better pun is "Dragan Ballz" he he
Aug-16-09  WhiteRook48: finally!!! I got it!!! 20...Qxc3!! because the king is very vulnerable on h1 due to the bishop on b7. 21 bxc3, and here I went off
21...Bxe4?? allows 22 Qxf3!! Bxf3 23 Rxf3 and white wins
Aug-16-09  Athamas: White very much loses if he plays Qxf3 in response to Bxe4
Aug-16-09  MrMelad: This puzzle was all need need, n-e-c-e-s-s-i-t-y. it was obvious black has a move because otherwise it wouldn't be a puzzle, it was obvious it was a queen move (really obvious) and it was obvious the knight had to be eliminated in order to allow white squares attack so the first move 20..Qxc3 came as easy as a Monday. Then it was only logical to open the center with 21..exf5 and not risk the bishop with Bxe4 especially if the queen cannot take the knight on f3 because of 22..Bxe4. After seeing so many favorite prospects on the white a8h1 diagonal, it couldn't fail.

Easiest week by far.

Aug-16-09  tacticalmonster: 1 Rxc3 Bxa5 2 Bxe4! Qg2! 3 Rxc2! ( 3 Qxc2 4 Bxc2 Rxf3 5 Be4 ) Qg3 4 Nxh2+ Kg1 5 Nxf1 Kxf1 6 Bxf5

2 Bxe4 Bxc3 3 Nxg5+ Qf3(forced otherwise Nh3#) 4 Bxf3+ Rxf3 5 Nxf3

If You look carefully, any move other than queen allows mate or losing the queen

2 Bxe4 Qa7 3 Nxg5+ Rf3 4 Rxf3 Kg2 5 Rxf5+

Aug-16-09  Athamas: You lose the queen either way... Bxc3 instead of Qg2 is much stronger

  OBIT: I'm looking at this one on Sunday evening, so I'm sure it's been analyzed out by now. But, I'll add the thought processes that emanated from my feeble mind anyway.

The first thing I notice is that I have allowed my queen to be trapped. No doubt I have some ingenious reason for that, and I figure the answer has to be either 20...Qxc3 or 20...Rxc3. (In a way, this one seems not so tough. The dire situation, with White about to lose his queen, suggests a drastic response.) After a few minutes of thought, I like 20...Rxc3 better because of the continuation 20...Rxc3 21. Bxa5 Bxe4 22. h4 Nxg5+ 23. Kh2 Rh3+ 24. Kg1 Rh1#, which is not there after 20...Qxf3. If White plays 22. Bxc3 instead, then I execute the main point to the capture on c3, which is 22...Nxg5+ 23. Kg1 Nh3#

OK, that took all of about 10, maybe 15 minutes. Really, I can't imagine there is anything else here. I mean, I just lost my frickin' queen (hopefully on purpose) and either this attack works or it doesn't.

Aug-16-09  Athamas: Sorry didn't see your second analysis.

The line I see is 1. Bxc3 Nxg5+ 2. Qg2 Bxg2 3. Kxg2

This is still an advantage for black but it is no longer completely winning like the other lines of play in Qxc3 continuations.

Aug-16-09  Eduardo Leon: This one I know by heart, since I read it from The Sicilian Labyrinth, pt. 2, by the great Lev Polugaevsky:

<20. ... Qxc3!!>

A beautiful queen sacrifice begins a decisive attack in the long diagonal.

<21. bxc3 exf5>

Of course, <22. exf5> would be suicide: <22. ... Nxg5+ 23. Kg1 Nh3#>. And <22. Be3>, to block the defense of the knight by the rook (<22. ... Rxc3>) would be followed by <22. ... Bxe4 23. Qxf3 Rxc3> (threatening <24. ... Rxe3>) <24. Rae1 Bxf3+ 25. Rxf3 Bxg5>, and black has more pawns in the endgame.

<22. Qe2>

A little trap: <22. ... Bxe4? 23. Rxf3!>, and suddenly white wins.

<22. ... Rxc3!>

Black eludes the preceding trap and systematically increases the pressure. Now, white can't play <23. Rxf3 Rxf3 24. Qxf3 Bxe4>, and, again, black has more pawns in the endgame.

<23. Be3>

White can try not to give back his queen, but he is doomed still.

<23. ... Bxe4 24. Rxf3 Bxg5!>

The last finesse. White's bishop is pinned against the rook, which is pinned against the king. The only way to avoid the deadly <25. ... Rxe3> is to unpin the rook.

<25. Kg1 Bxf3 26. Qxf3 Bxe3+>

And, of course, this is a won endgame.

Aug-16-09  Eduardo Leon: White could have avoided all this trouble with <18. Bg2> and only then <19. f5>.

  TheBish: P Kral vs Barlov, 1987

Black to play (20...?) "Insane"

Material: Black is up a piece, but his queen is trapped.

Candidate moves: Rxc3, Qxc3

20...Rxc3 21. Bxa5 Bxe4 22. Bxc3 Nxg5+ 23. Qg2 (not 23. Kg1?? Nh3#) exf5 24. Rxf5 Bxg2+ 25. Kxg2, and the game is far from clear. With two pawns for the exchange, Black is equal but no more.

20...Qxc3!! is the best move. Now 21. bxc3 (obviously forced) exf5! (better than 21...Bxe4 22. Qe3 Nxg5+ 23. Kg1 exf5, although this isn't bad) 22. Qe2 (or 22. Qe3 Bxg5!, but not 22. exf5? Nxg5+ 23. Kg1?? Nh3# or 22. Qxf3?? Bxf3 and wins) Rxc3! (not 22...fxe4 or 22...Bxe4 because of 23. Rxf3) 23. Be3 (or 23. Ba5 Bxe4 24. Bxc3 Nxg5+ 25. Qxe4 fxe4 and wins) Bxe4 24. Rxf3 (pretty forced since both Nd4+ and Rxc2 are threatened) Bxg5 25. Kg1 (or 25. Re1 Rxe3 26. Qxe3 Bxe3 27. Rxe3 Bxf3+ with an easy win) Bxf3 26. Qxf3 Bxe3+ 27. Kf1 f4, and Black has a big material advantage.

Aug-16-09  karnak64: Well, as Bob is my witless, there's no way I ever would have seen this.

Or even considered it.

The only thing I thought when I saw the position was, "how'd this position come about?"

So I watch, read, and learn. And hope for Monday. My hat's off to my many betters here.

Aug-17-09  LIFE Master AJ: To clarify an earlier post ...
this was the first time I had ever gone Monday-thorugh-Sunday ... and successfully solved all of the daily puzzles.
