|Jul-04-12|| ||MountainMatt: 6. exf7+ should lead only to a two pawn advantage for white, as opposed to the disaster black found in the text (white, nonetheless, should win anyway). This seemed easy for Wednesday, a day on which I'm almost always stumped! Is CG taking it easy on us for the holiday?|
|Jul-04-12|| ||Oxspawn: 6. exf
6. … Kxf
7. QxQ and black will likely also lose the white bishop or a number of pawns
7. QxQ KxQ
8. fxN =Q RxQ
and white is a knight and two pawns up
Is there a mate here? – If so, I haven’t found it.
What about playing
6. Qa4+ first. But after 6. Ke7 the pressure seems to be released.
Let’s go and see.
|Jul-04-12|| ||Oxspawn: Aaah. I hadn’t even counted to see white was already a knight down, and I had not seen the final devastating punchline. No wonder the games I play against my computer are often this short.|
|Jul-04-12|| ||RMKvdS: Wow, missed the last one. Calculated to fxg8=N and then missed the kill move. First wednesday I missed in ages, nice combo.|
|Jul-04-12|| ||Abdel Irada: <Excelsior Express?>|
This does indeed seem to be underpromotion week on CG.com. In this puzzle, we see a theme that should be familiar to all those who play (or play against) the Albin Counter-Gambit.
White begins with 6. exf7+, leaving Black two options:
(1) 6. ...xf7?; 7. xd8 .
(2) 6. ...e7; 7. fxg8=+!, when Black can lose quickly with
(2.1) 7. ...xg8?; 8. g5+ and White wins the queen, or slowly with
(2.2) 7. ...e8; 8. xd8+, xd8; 9. bxc3, when White enters the endgame two pawns up.
|Jul-04-12|| ||Oxspawn: <Once:>
<“So the career of this pawn goes something like this....
7. N-g8+ table
I come from nothing. I go to nothing. I am not afraid.”>
If the knight had consciousness and self-awareness (“I move crooked, therefore I am”) it might wonder (with hope) whether after the end of the game, it might be taken out of the box again, to play another day. It is easier not to be afraid when you have hope. The pawns have been assured that they come back as queens, the kings and queens don’t care so long as they are waited on hand and foot in the box as on the board. The bishops believe they retain a molecular memory of the laying on of hands (a player who loses a lot goes on losing if they move their bishop.) The rooks deny there is an end of game or a box, only straight up and down rooks. Only the knights are philosopher warriors. And even knights have their doubts.
If you believe that the box is the end of chess, you need another way to deal with fear.
|Jul-04-12|| ||gars: This POTD seems to be easier than yesterday's.|
|Jul-04-12|| ||zb2cr: Ah, another underpromotion!
6. exf7+, Ke7 (6. ... Kxf7? loses the Queen); 7. Nxg8=N+! and now if Black captures 7. ... Rxg8; 8. Bg5+ costs him the Queen. Probably 7. ... Ke8 is best,

|Jul-04-12|| ||poszvald: LoveThatJoker!
No, I do not seek anything particular, just wanted to know if there are such possibilities or not. Thank You really much.
|Jul-04-12|| ||Wyatt Gwyon: <Oxspawn> what do you do for a living?|
|Jul-04-12|| ||BOSTER: It looks like a magic.
White knight being taken on "c3" suddenly shows up on "g8".
<CG> continues to juggle.
See the trick. After move 5...dxc3? black was up a knight.
But after 7.fxg8=N+ white who is up the knight.
Seeing that his own knight changed the color, black decided that something wrong with his eyes and was sent to doctor.
In corr. chess maybe black should spend couple more weeks before playing move 5...dxc3?
|Jul-04-12|| ||Once: <Oxspawn> Perhaps, my friend, perhaps.|
I imagine the poor prawn has a miserable life. Before the game, he agonises about whether he will get to be a glory-hound as the e or d pawn, face the terrifying prospect of being in the f pawn firing line, or even the game winning outside passed a pawn.
It's the not knowing, that's the worst thing. Will I be playing with the elite on top board or man-handled by some snotty-nosed kid who doesn't wash his hands?
We may think that the prawn dreams of promotion. But all that happens to the humble footsoldier is that he gets substituted off the field, just as things get interesting. Imagine his pain and disappointment. He has spent five or six moves steadily marching up the board. All the time under fire by the much bigger and more powerful pieces. And when he does get to the eighth rank, what happens?
Instantly, he is sent to the sidelines to sit out the rest of the game. Meanwhile his place is taken by one of the fatter pieces ... and probably one that has already got itself killed and is getting a second chance.
A second chance! Pah - we prawns never get a second chance. No-one ever underpromotes to a prawn.
Unless, of course, that is what CG has in store for us on Sunday?
|Jul-04-12|| ||gawain: What an odd position! Looks like 6 exf7+ will win|
|Jul-04-12|| ||gawain: Oh... Missed the underpromotion.|
|Jul-04-12|| ||CHESSTTCAMPS: In this opening trap position, white is down a pawn for a piece, but can exploit the lineup of queens on the open file to decisive advantage:|
Many would now be satisfied to regain the piece with 7.Qxd8+ Kxd8 8.fxg8=Q Rxg8 9.bc with a two-pawn advantage on the king-side. White can try for more with
7.fxg8=N+! Ke8! (Rxg8 8.Bg5+ wins) 8.Qxd8+ (Qb3? cxb2 is asking for trouble) Kxd8 9.Bg5+?! Ke8 (Kc7 10.Ne7 h6 11.Bf4+ and white's extra knight escapes to d5) 10.Nf6+ gxf6 11.Bxf6 cxb2 12.Bxh8 bxa1=Q+ 13.Bxa1 Bb4+ 14.Kd1 with a two-pawn advantage that should be won.
I prefer 9.Nh6! gxh6 (cxb2? 10.Bxb2 and the Nh6 escapes) 10.bc and the two-pawn advantage is stronger with black's doubled h-pawn and equal pawns on queen-side.
Time for review....
|Jul-04-12|| ||scormus: <sevenseaman: <I come from nothing. I go to nothing. I am not afraid.>
Be it the King, be it the Knight or be it the commoner; everyone goes into the same box when the game is over.>|
Oui, moni ami. Tout a fait.

Preview of coming attractions!

Under the normal rules of chess this is mate in 4 for White; however, <1.cxd8P> is mate in 3!
The threat is 2.f8Q#, and Black's only helpful defenses are bishop checks. However, after the "pawn promotion", 1...Bf5+ 2.Rxf5 is not stalemate as Black must walk into 2...Ke7 3.f8Q#. An even neater line is 1...Bc6+ 2.bxc6 Kxc6 3.b5#.
Other promotions will not work. If White promotes the d-pawn to a queen or rook instead, Black is stalemated immediately. After 1.cxd8B Bf5+, White cannot capture without producing stalemate (since the new bishop protects e7), and 2...Bxc8 will prevent mate on the next move. Similiarly, after 1.cxd8N Bc6+ 2.bxc6 would be stalemate since the new knight protects c6, and other moves allow Black to survive an extra move with 2...Bxa8.
Would it surprise you to know this is a composition by Sam Loyd?
|Jul-04-12|| ||scormus: <Phony Benoni> Thanks, I knew this week should see promotion to a pawn. Now I can sleep easier. |
<Sam Loyd> I might have guessed ;)
|Jul-04-12|| ||sevenseaman: A pawn when it dies can transmogrify into any of the other bigwigs of the chessboard (bar the K)but it cannot retain its own identity and powers.|
It is debatable if it enjoys losing its identity, for what a P does while it is living is incomparable.
In this position all participate; it is a concert that produces a 3-mate.

White to play.
|Jul-04-12|| ||uscfratingmybyear: I "solved" this immediately since I recently looked at the Albin Counter Gambit video on YouTube done by Jerry for Chess Network and this idea figures directly in it. He also shows several slick side lines-it's short and to the point. He also covers the Fishing Pole trap nicely.|
|Jul-05-12|| ||kevin86: White underpromotes and wins the queen!|
|Jul-06-12|| ||TheaN: Wednesday 4 July 2012 (on 6 July)
Material: Black up, !
Candidates: <[exf7† with fxg8=N†]>
This is a very famous trap, so to say, usually shown from Black's point of view in the Albin Countergambit in the QGD: 1.d4 d5 2.c4 e5 3.dxe5 d4 4.e3?! Bb4†! 5.Bd2?! dxe3! 6.Bxb4? exf2 7.Ke2 fxg1=N†. After that, the same happens as what executed here:
<6.exf7† Ke7 7.fxg8=N† Ke8> Rxg8 8.Bg5† is toothless.
<8.Qa4† Bd7 9.Qe4† > seems to give the opportunity to disrupt the Black king even more, or at the expense of a piece down for Black. After Kf7, is Black were to try to get the Knight, the simple e3 seems to create enough headaches for Black. This is however, beyond the scope of the puzzle.
