|Aug-23-11|| ||ConstantImprovement: |
I think the critical variation is
22. Qf6:+ Rg7
(22. ... Rf6: is easy; 22. ... Bf6: 23. Rh7:+ Kh7: 24. Rh4+ Bh6 25. Rh6:#)
(23. Qg5 f5:)
23. ... Kh7:
(23. ... Kg8 24. Rg7:+ Kh8 [24. ... Bg7: 25. Qg7:#] 25. Rh4#)
24. Rh4+ Kg8 25. Nh6+ Kh7 (Kh8) 26. Nf7:+ Kg8 27. Rh8#
|Aug-23-11|| ||Gilmoy: A swift pattern-match for Anastasia. Run down the checklist and spot the extra defender/anti-defender pair, here the Nf6.|
OTB, as early as <9.Ne2> White envisions Ng3-h3 and a B chase, or half-open g for a K-side attack. <14.Nf5> is canonical: White overwhelms g7/h7.
Black's plan of <11..Bd6 12..Qc7> is too milquetoast: Schlechter promptly offers h2 for 3 tempi, and Bendiner doesn't even want it. This is why we play for the <bishop thing> Bb8-Qc7 to create a real threat.
<14..Rg8 18..g6> happens to fill in the rest of Anastasia. In general, Black may have other K-side defensive tries, e.g. h6 or (where applicable) Nf8. g6 "solves" the Bd3 problem, but creates an h-problem. I've dueled a couple fish who saw it coming and played n-1 only-moves correctly (mu-ha-ha), and several more who didn't see it at all.
<Phony Benoni: And 23...Kg8 just postpones the mate by a move after 24.Rh8+!> Damn me, ah know that pattern too, it's called --
|Aug-23-11|| ||agb2002: The material is even.
Black threatens 22... gxf5 and 22... Nxg4 (23.Rxh7+ Kxh7 24.Qh4+ Nh6).
The black knight defends the spot h7. Hence, 22.Qxf6+:
A) 22... Rxf6 23.Rxh7+ Kxh7 24.Rh4+ Bh6 25.Rxh6#.
B) 22... Bg7 23.Rxh7+ Kxh7 24.Rh4+ Bh6 25.Rxh6#.
C) 22... Rg7 23.Rxh7+
C.1) 23... Kxh7 24.Rh4+ Kg8 25.Nh6+ Kh7(8) 26.Nxf7+ Kg8 27.Rh8#.
C.2) 23... Kg8 24.Rxg7+ and mate next.
|Aug-23-11|| ||whiteshark: I have had the right trains of thought.|
|Aug-23-11|| ||dufferps: 22. Qxf8+ What a brilliant move by Schlecter. Naturally, Bendiner captures the queen with the rook, and we see the ending as it was played. But interposing with the bishop or with the rook would not save black from the onslaught of the rooks and knight.
The most interesting continuation is:
22. ... Rg7,
23. Rxh7+ Kxh7
24. Rh4+ Kg8,
25. Nh6+ Kh7 (or...Kh8)
26. Nxf7+ Kg7
Interposing with the Bishop is no better for black,
22. ... Bg7
23. Rxh7+ Kxh7
24. Rh4+ Bh6
|Aug-23-11|| ||DarthStapler: Yeah I figured that out after I made the comment|
|Aug-23-11|| ||TheTamale: An interesting puzzle. I got it because I knew there was something to look for. The chances of me seeing it in an actual game are less than one in 250 trillion.|
|Aug-23-11|| ||jussu: Now this three-mover is more like a Monday puzzle; yesterday's combination was a little subtler.|
|Aug-23-11|| ||Patriot: My analysis is the same as <agb2002>. 22...Rg7 gave me the most trouble and I was not as efficient as I would have liked time-wise. After 26.Nxf7+ Kg8 it took me a bit to see that 27.Rh8 is mate! It was all forced but still a good exercise in practicing visualization.|
<<TheTamale>: An interesting puzzle. I got it because I knew there was something to look for. The chances of me seeing it in an actual game are less than one in 250 trillion> During a game no one will tell you there is a combination present but there is a strong sign here that is useful OTB. It says "The black king is completely immobile so start looking at all checks, captures, and threats!"
|Aug-23-11|| ||numbersguy70: Strange that a world champion contender would miss 14.Ng3, winning a knight easily. After BxN, PxB, Black has no way to prevent g4.|
Black also could have forced a rook trade on move 21, taking serious wind out of the attack. Throughout, his overly defensive play (shuffling king and rook into the corner was premature and gave up initiative...and fear of the open file prevented Bxh2 which would have provided a passer) eventually caused him to lose a game which he appears to have had a least a slight advantage.
|Aug-23-11|| ||kevin86: Easier than yesterday! The queen sac theme is a usual Monday theme (maybe the puzzles were reversed). The final mate seems to be a combination of Anastasia's mate and Arabian Mate.|
|Aug-23-11|| ||Schach and Awe: Missed the sacs that lead to the Mating Net, despite the fact that the puzzles early in the week tend to be 'sac happy'.
I decided to do a post-mortem on the position, and despite the marshaling of enormous forces on the Kingside, a move such as 20. .. Be7 to protect the N while also keeping White's Nf6 from repositioning anytime soon due to the nasty discovered attack on the White Q and R, seem to keep Black in the game. There are few opportunities for counterplay however, but a draw is still within reach with Best Play.|
|Aug-23-11|| ||Uvulu: Looks like a mate in 6 starting with Qxf6+ to me:
A) 22. ... Rxf6 23. Rxh7+ Kxh7 24. Rh4+ Bh6 25. Rxh6#
B) 22. ... Rg7 23. Rxh7+ Kxh7 (23. ... Kg8 24. Rxg7+ Bxg7 [24. ... Kh8 25. Rh4#] 25. Qxg7#) 24. Rh4+ Kg8 25. Nh6+ Kh8(h7) 26. Nxf7+ Kg8 27. Rh8#
C) 22. ... Bg7 23. Rxh7+ Kxh7 24. Rh4+ Bh6 25. Rxh6#
Let's check now...

His dog as trouble Bend
And so lost in cups my tash! Sauce rend
The milky grains of time rooks end
|Aug-23-11|| ||Kolyas: <chrisowen> Great poem.|
So colorful. So alive, yet simple and to the point.

Not very colourful (rather milky, in fact!), the poem's crowning glory is it's brevity.
|Aug-23-11|| ||MaxxLange: It seems like there were a lot of situations like this in older games: someone building up a huge K-side attack, with the other guy just trying to defend every square. Modern players seem to prefer a less passive approach.|
|Aug-23-11|| ||morfishine: Great going <everybody> who worked through <22...Rg7>. I didn't even consider it. Very good|
|Aug-23-11|| ||Kolyas: <Boerboel Guy> <chrisowen> like a fine wine, is appreciated with age.|
Don't criticize what you don't understand.
"Try loping upwardly and longily in his brogans for a league before thou thusly addeth unbecoming comment."
See, it is not so easy to do what... ever it is that <chrisowen> does with such effortless ease.
Truly, a prophet is never appreciated in his own country.
|Aug-23-11|| ||chrisowen: <Kolyas> <Boerboel Guy> select concorde ground for table you rope a doper? lol ;) |
Chance again for dim view far cry it I seas hell gain mastery light up waire gods will peace among you too
|Aug-23-11|| ||Kolyas: <chrisowen> Truly, those are words to live by.|
|Aug-23-11|| ||stst: Easy!? - Quite a lot of variations!
Some analyses below, might still miss some...
22.QxN+ (main line, get rid of nuisance N which protects h7P from 22.RxP+):
IF (A)22....Bg7; 23.RxP+ KxR; 24.Qh4+ Bh6; 25.QxB#
IF (B)22....RxQ; 23.RxP+ KxR; 24.Rh4+ Bh6; 25.RxB#
IF (C)22....Rg7; 23.RxP+ Kg8; 24.RxR+ BxR; 25.QxB# (if 23....KxR; 24.Rh4+ Kg8;
25.Nh6+ Kh7/Kh8 (same effect); 26.Nxf7 dis+ Kg8; 27.Rh8# K cannot take N protected by Q!)
|Aug-23-11|| ||stst: < TheTamale: An interesting puzzle. I got it because I knew there was something to look for. The chances of me seeing it in an actual game are less than one in 250 trillion.>|
Interesting math, wonder who can check that - 250 trillion, 300 trillion, 5 trillion trillion etc etc... what makes the difference; who to prove or/nor disprove??
|Aug-23-11|| ||BiteByBits: the rook on the h-file sacrificing itself by taking black's pawn is a common theme, in this case you can see that white has a rook on g4 and h4, therefore you can sacrifice the h4 rook to open the h-file and then use the g4 rook to check the king again (the black king is forced to take the sacrificing white rook)
22.Qxf6+ Rxf6 23.Rxh7+ Kxh7 (all black moves are now forced!) 24.Rh4 Bh6 25.Rxh6#|
|Aug-23-11|| ||sevenseaman: <morfishine> Yes, 22...Rg7 is an interesting new angle. I think <duffersps, ConstantImprovement & agb2002 & Patriot> are the ones who had the exhaustive enough approach to think of it.|
Though nothing avails, it shows how thorough one needs to be and look at all the angles. Kudos to the foursome.
