|Sep-14-11|| ||SimonWebbsTiger: In lieu of a <Once> story....|
Cinderella was not enjoying herself. She was in the back room once again, with only the rookie to entertain her whilst Bob and Brian were out in their Ferrari cars down routes a2-g8 and a1-h8. Her hateful, ugly sister giggled at her from afar after all the fun she had had. Fairy Godmother Caissa took pity and spirited a carriage to take her to the palace. Sure enough: Cinderella took a hesitant step forward and did go to the ball, capturing the King's attention.
Before complaints rain in: I can't fit <Once>s slippers....
|Sep-14-11|| ||agb2002: White is a pawn down.
Black threatens 23... Bxd5 and 23... hxg5.
White would win immediately if there were a way of placing the queen on g6, taking advantage of the position of the bishop pair (pinning the pawn on f7 and pressing on g7). Therefore, 23.Qb1(c2,d3):
A) 23... hxg5 24.Qg6 and mate in two.
B) 23... Rc8 24.Qh7+ Kf8 25.Qxg7+
B.1) 25... Ke8 26.Qxf7+ Kd8 27.Qf8#.
B.2) 25... Ke7 26.Qxf7+ Kd6 27.Ne4#.
C) 23... g6 24.Qxg6#.
|Sep-14-11|| ||cocker: Not sure what the technical term is, but I think of this as 'the old one-two'. I.e. hit him with Qd3 and while he's still reeling from that follow up with Qg6.|
|Sep-14-11|| ||Memethecat: brain malfunction this morning, after giving up and going through the game got to last move Qd3 & it STILL took a minute to see the solution... Lesson learnt, wait till that first coffee kicks in before trying to solve chess problems.|
|Sep-14-11|| ||scormus: <cocker: ... 'the old one-two'> couldnt put it better myself|
<SWT .... can't fit <Once>s slippers>
neither can I ;)
really curious what makes a move sequence hard to find. Today is really quite easy but <among others> I needed about 15 mins before it clicked.
|Sep-14-11|| ||morfishine: Only found this after viewing from the Black side!...and I ended up with <dzechiel>'s line:|
<23.Qb1> threatening mate at <h7> (forking the Bishop on <b7> at the same time) does the trick. Mate is forced in either case: 23...hxg5 24.Qg6 and mate at <g7> [after 24...Be5 25.Bxe5].
Or Black can lose one move faster with 23...Bxd5 24.Qh7#
Or he can lose even faster by resigning. :)
|Sep-14-11|| ||fetonzio: h6 looks pretty terrible|
|Sep-14-11|| ||Gilmoy: <BlackWaive: … recently saw a similar tactic in Kamsky vs Svidler, 2011>.|
<Morten: … I just saw a move similar to the pushy 24.Qg6 in another game>
<gofer: ... recognise this pattern because we had it recently ... the GOTD "Re2 from nowhere" move …>
<rilkefan: ... been primed by Svidler's ...Re2 combo.>
Even when we vaguely know that the B-pair is good, here's a(nother) deep pattern with a tactical sting, which is definitely worth imprinting. g7/h7 is the canonical "other pointy dood" sac (which becomes a bowling alley for a two-R mate: R lift ftw). f7/g7 can enable a Qg6, "if only" you first lure h6 somehow. In this game, White offers a piece just to get the h6 tempo, which has the feel of a Greco sac. (In another configuration with f6/Kh8, i.e. LSB-sees-g8, White could have had the Greco dance Qh5-Qg6 forcing hxg5, and then the stepback Qh5# -- so my brainmelt flowed down that channel first.)
Note how <16.Bd5> first neutralizes Black's own "pointy dood" threats, probably content with 16..Bxd5 17.Qxd5 and a deci-pawn spatial advantage. Black outsmarts himself: <17..Qd6> is a devious constraint on White's Nf3/O-O, forking Bd5 and (the specter of) Qxh2#. Flaw: It's not a threat just yet, so it amounts to giving White a <free tempo>. That's hard enough to prove correct in the midst of a mating combo! This early in an open middlegame, it invites swift and/or deep replanning. White responds with a deeper imperative: "a tempo is worth more than a Rook" -- and promptly offers P+N. It's dangerous to <cede initiative> to somebody who's willing to sac!

Hard working, hardly working carry different connotations. Which one applies to you <scormus>? Yesterday on the <Chuky vs Grischuk> yours was the first comment that hit my eyes< c'mon Chuky, whats keep you so long?> and I thought my favorite must be winning. When I saw the position it looked like a dead draw, which it turned out to be. Whats going on, I say. Are you practicing your sentence oxymorons or what? Doing it<accidentally on purpose>?|
|Sep-14-11|| ||ProjectR: Missed it,yet its so simple after seeing some of the above comments..Think im just having a a bad day all round..|
|Sep-14-11|| ||Jazzer32: Same as <BlackWaive>, found it only cause it was in Kamsky - svidler game. No way I could find it without that game|
|Sep-14-11|| ||Patriot: I found the key move, 23.Qd3 in light of 23...hxg5 24.Qg6. This took more than 5 minutes I think. It's one thing to solve a puzzle and quite another to see stuff like this OTB when your time is going down.|
I considered 23.Qd3 earlier in my thought process because "mate threats" are just below "checks". But I didn't see the pattern right away after 23...hxg5 and looked for other candidates. 23.Nxf7 looked tricky but I don't think it works.
|Sep-14-11|| ||kevin86: This was pretty easy-though white could have won by Qb1 or c2 as well.If he tries to escape with a rook move,Qg6 threatens TWO mates.|
|Sep-14-11|| ||ounos: Qb1 was more classy, and might have lead to the next move of the combination actually be played. Now it was 100% obvious what white was going for, and black resigned :)|
|Sep-14-11|| ||estrick: <cocker: Not sure what the technical term is, . . . follow up with Qg6>|
I think this one would fit in the pattern Chandler (and many others) call a "Greco's Mate."
In the following pages he continues the theme with the headings, "More Qg6 Bombshells" and "Korchnoi's Manoeuvre"

Black congestion in the corner gives the depleted White a chance. Easy. I have no doubt you will enjoy it, if you do solve it.
|Sep-14-11|| ||scormus: <sevenseaman>
I can hardly answer that question
.... Germany football team playing very hardly ..... Do vist, you are mostly welcome.
Ja, das ist meain probleme, die mehrsprache welt in ich wohne. Stark oder peinlich?
See wha' I mean 'Arry
PS First Judit and now Chuky :(
|Sep-14-11|| ||tbentley: Got it shortly after noticing the threat of Qh7# (and then hxg5 Qg6 etc.).|
The pawn on g5 first blocks the king, then the g6 pawn.
|Sep-14-11|| ||dark.horse: Got the 23.Qb1 variation.|
|Sep-14-11|| ||Dr. J: <Once: 23. Qd3 Rc8 24. Qh7+ Kf8 25. Bxg7+ Ke7 26. Qe4+ Be5 27. Qxe5+ Kd8 28. Nxf7#>|
Or 23 Qd3 Rc8 24 Qg6 and mate next move.
Meanwhile, I wonder if <cg> might have chosen this puzzle to contradict the "unique solution" argument I brought up yesterday ("Son, you're giving yourself far too much credit", I think I hear somebody whispering). Please note, I never said the POTD had to have a unique solution, only that On. That. Particular. Occasion, that was the clue that raised my suspicions and sent me back on the right track.
[And I don't know Any. Other. Way. to Simulate. Italics.]

(Also for those who tried but did not find the solution. Isn't it easy?)
|Sep-14-11|| ||tbentley: <sevenseaman><<tbentley> <The pawn on g5 first blocks the king, then the g6 pawn.> Is not very clear to me.>
If after 1...hxg5 the pawn disappeared, black could avoid mate with 2...Kg5 or 4...g5.|
|Sep-14-11|| ||ku0826: Watching the mating spot h7,
I finally found out Q to d3,c2,b1.
|Sep-15-11|| ||sevenseaman: <tbentley> To start with there is no Black(or White)P on g5. A Black P gets to g5 only after 1...fxg. Since the K is at <f7>, even if <g5> were to be still untenanted, only <3...Kg5> would be possible not <2...Kg5>. That is the cause of my confusion.|
Unless we are now in agreement, you could perhaps write down the lines as you see them in order to close the communication gap.
