|Feb-15-12|| ||LoveThatJoker: <kahen> Magnet sacrifice makes a lot of sense and has a nice ring to it too!|
Traditionally, however, a move such as 33. Qg7+ would be called an attraction sacrifice. Also, if you look at the above posts you can see that it can also be called a decoy sacrifice.
|Feb-15-12|| ||al wazir: You say tomato, I say tomahto. Polgar says 33. Qg7+, I say 33. Qh7+.|
|Feb-15-12|| ||goldfarbdj: I didn't find the game line. I wanted to try Rbxf7, with the pretty point that if Black tries 33. ... g5+ 34. Kh5 Qxh3+ 35. Rxh3 Kxf7, then 36. Qg6 is mate anyway. But after 33. ... Re4+ the game gets complicated -- I think White is still winning, but the game line is obviously better.|
|Feb-15-12|| ||newzild: WENEREI: 2:35-2:36
Black has unpleasant threats, so White must act fast. My first two candidates 33. Qxg6+ and 33. Qf8+ do not work. However...
33. Qg7+ Kg7
a) 34...Kh6 35. Rh7#
b) 34...Kg8 35. Rg7+ Kh8 36. Rh7+ Kg8 37. Rbg7#
c) 34...Kh8 35. Rh7+ Kg7 36. Rbg7#
Fairly standard stuff. About the right level of difficulty for a Wenerei, I think.
Time to check...
|Feb-15-12|| ||scormus: Neat finish. I like the elegance of the inevitable #, BK's escape is b;ocked by the WBc5 and the WKh4, the 2WRs do the deed|
|Feb-15-12|| ||TheBish: Judit Polgar vs L B Hansen, 1989|
White to play (33.?) "Medium/Easy", Black is up a pawn.
I've seen this one before. Black survives 33. Rbxf7 Re4+ 34. R3f4 Qf2+! 35. Kg4 Qg2+ with a draw, or 35. Kg5 Qg3+ 36. Rg4 Qe3+ 37. Rff4 (not 37. Kxg6 Re6+, and 37. Rgf4 Qg3+ repeats) Re8 and White's pieces are all tied up.
The key is finding a forced mate.
33. Qg7+! (Qh7+) Kxg7 34. Rfxf7+ Kg8 35. Rg7+ Kh8 36. Rh7+ Kg8 37. Rbg7#.
|Feb-15-12|| ||Once: I think I've worked out what I really want most from the world. It's not money or fame or Angelina Jolie dipped in caramel.|
What I really want is a button to make my car go faster.
Think about it. Knight Rider had its "super pursuit mode". When the Hoff needed to get somewhere quickly (at least twice per episode), he would hit a button - usually somewhere ineffably cool like on the roof - and KITT would speed up. Okay, so the editor would speed up the film and slow down all the other cars. But it felt like KITT was going faster.
Or when they needed to jump over something, he hit the turbo boost button and then the camera would switch to an angle to hide the ramp they'd placed on the highway. Woosh.
James Bond had a button to turn his Lotus into a submarine. When I was a nipper, I wanted one of those even more than I wanted to spend quality time with his co-star Barbara Bach (who bizaarely married Ringo Starr - proving that ugly blokes can sometimes strike gold).
In Mad Max just about everyone had a button to fire up the nitrous oxide or the supercharger or ... something else technical. Apart from Tina Turner, who just had lots and lots of hair.
Top end cars even have "sport" buttons. I'm told that the big BMW's have a button marked M which means "go faster". Or perhaps that should be "mach schneller" or something like that? This incidentally proves that BMW weren't paying attention in the Bond films. The button really should have been marked Q...
And in chess we have a button to make an attack go faster. Only our button is called "check". If we can string together a series of checks, it's like our opponent is standing still - that old knight rider trick of surrounding KITT with lots of ordinary cars driving v.e.e.e.r.y sl..o..w...ly.
In today's POTD, white would love to play Rfxf7 or Rbf7 threatening unstoppable mate. But that's way too slow. Because it doesn't come with check, black gets a chance to defend with a check of his own. Re4+ forces exchanges and the attack disappears.
White needs to increase the pace so that black doesn't have time for Re4+. And that means giving check with a queen sacrifice so that Rfxf7 lands with check. And the rest is simply a car crash - for black.
When VW designed the new beetle, they built a flower vase into the dashboard. Ferrari give you a dial on the steering wheel to select road-race-track or something equally red blooded.
Guess which of these cars is aimed at women buyers and which at men?
I rest my case.
|Feb-15-12|| ||LJLMETAL: 33... Kxg7
34. Rfxf7+, Kg8
35. Rg7+, Kh8
36. Rh8+, Kg8
|Feb-15-12|| ||Gilmoy: Cute: Judit evokes Fischer's dainty Q(g4)-g3-g4-h5 creep in Fischer vs Benko, 1963. Ostensibly she controls d4, then pokes at d5, then harasses f7.|
Black cleverly deflects her away from the threat ...
|Feb-15-12|| ||rhickma4: This took me quite a while, and there are two solutions!|
33.Qg7+ Kxg7 34.R3xf7+ Kg8 (34...Kh6 35.Rh7#, 34...Kh8 35.Rh7+) 35.Rg7+ Kh8 36.Rh7+ Kg8 37.Rbg7#
33.Qh7+ Kxh7 (33...Kf7 34.Qxf7#) 34.R3xf7+ and as above.
|Feb-15-12|| ||morfishine: <33.Qg7+> or <33.Qh7+> force mate. |
Black king is cornered: hemmed in by White's Bishop covering <f8> and his own pawn on <g6>. White King completes the net
|Feb-15-12|| ||Memethecat: Dismal failier, went for <33Rbxf7>|
|Feb-15-12|| ||agb2002: White has a bishop for a knight and a pawn.
Black threatens to win the queen or mate in six: 33... Re4+ 34.Qf4 (34.Rf4 Qf2+ 35.Kg4 f5+ 36.Kg5 Qxf4+ 37.Kxg6 Re6+ 38.Kh5 Q(R)xh6#) 34... Qxf3, etc.
Pattern recognition finds a quick mate with the rooks: 33.Qg7+ Kxg7 34.Rfxf7+ and mate in three at most.
|Feb-15-12|| ||whiteshark: <Memethecat+goldfarbdj> Great minds fail alike. :D|
|Feb-15-12|| ||Rook e2: Hm, I wasn't the only one who -for some reason- found Qh7+ in stead of Qg7+. Oh well, both work. Rather easy when the move has to be forced.|
|Feb-15-12|| ||OhioChessFan: Yesterday took a distressingly long time. Today it took me about 10 seconds to realize White had to check, and go with Qg7+. And the rest plays itself.|
|Feb-15-12|| ||rhickma4: Can anyone think of another game in which there are two winning Q sacrifices?|
|Feb-15-12|| ||Limpin Kt: Ugh! Todays puzzle was easy! It takes just 3-4s to find d weak f7 point- den another consideration s advanced king- 1Qh7! Solves it :)
just finshed a long chess game wid a fren o mine, wid lot of mistakes, finally managed stop his connected passed pawns wid kt blockade and finished wid an endgame advantage and won, strange how i couldn't find combinations in real chess play :(|
|Feb-15-12|| ||polarx: <Once>, you really need to print three or four of your comments here and visit a couple of newspapers or magazines. I am sure they will say some things need to be tweaked here and there but I also think you never fail to bring an imaginative twist to such an "arid" (but we all know it isn't) matter as chess. Today's connection between the go-faster button in KITT and check in chess and how once you press the check button the opposing pieces seem to stand still while one's pieces move in fast-camera action is just brilliant and I liked the way you kept the suspense and that idea hidden almost until the end of your "column".|
You would not be the first to do such a thing as going "professional". Giving it a try won't kill you. Well, basically that's it. I am going to press the "Kibitz!" button quickly before I have time to erase the whole message and leave it for another day. I think it deserved to be said at least... once.
|Feb-15-12|| ||zb2cr: I spent over a minute looking at 33. Rfxf7 before seeing the game move.|
|Feb-15-12|| ||Benzol: <rhickma4> There is this game where three black queens get the chop.|
Bogoljubov vs Alekhine, 1922
|Feb-15-12|| ||paavoh: Must gain time, so Qxg7+ to gain tempo followed by Rfxf7 and a mate with BK on g8 or h6. Thought this was a bit obvious for a Wednesday game.|
|Feb-15-12|| ||CHESSTTCAMPS: In this middlegame attacking position, black has the material advantage of N+P for a bishop, but white has the attacking advantage of having all pieces directed towards the black king, while two black pieces (knight+Rd8) do nothing at all to threaten the white king. At first I looked at 33.Rg3??, but Re4+ 34.Rg4 Rxg4+ 35.hxg4 Qh2+ 36.Kg5 Qd2+ is a very convincing refutation. Not surprisingly, there is a forcing solution available:|
33.Qg7+! Kxg7 34.R3xf7+ Kg8 (Kh6 35.Rh7#) 35.Rg7+ Kh8 36.Rh7+ Kg8 37.Rbg7#
|Feb-15-12|| ||Penguincw: Why didn't I saw that?|
|Feb-15-12|| ||newshutz: <Once> re: <polarx>|
You really should.
