|Mar-08-11|| ||CHESSTTCAMPS: In this opening position, white is temporarily down a piece, but black's play has left fatal weaknesses on critical dark squares, especially f6. Evidently black has just played 7...Bg7xd4 instead of 7... Nxd4 8.Bxe7 winning the queen. From the puzzle position, white simply plays:|
8.Qxd4! leaving no good defense.
Interesting but weaker is 8.Bxe7? Nxe7 9.Qxd4 O-O! 10.Nf6+ Kh8 (Kg7? 11.Ne8+ Kh6 12.Qh4#) 11.Nxd7+ f6 12.O-O-O Nf5 with counterplay. Of course, keeping the DSB on the board to exploit the weak dark squares makes much more sense.
A) 8... Nxd4? 9.Nf6+ Kg8 10.Bh6# is obvious. So is
B) 8... Rf8? 9.Nf6#
C) 8... Rg8? 9.Nf6+ Kf8 10.Bh6+ Rg7 11.Nxh7+ Ke8 12.Qxg7 wins.
D) 8... O-O 9.Nf6+ Kh8 10.Qh4 h5 11.Nxh5 gxh5 12.Qxh5+ Kg7 13.Qh6+ etc is a familiar winning tactic.
E) 8... f6! 9.Nxf6+ Kf7 10.Qf4 d6 11.Nd5+ Bf5 (Kg7? 12.Bf6+ Kxh7 13.Qh4+ etc) 12.Nf6 with +2P and threat of 13.e4.
More to this one, I think, than first meets the eye. Time to review...
|Mar-08-11|| ||stst: That's the first move I saw, not much Bk can do, nor, as one says, view it as a gym, today's a very light exercise, not much we extract from it.|
Since W's Q-B pair is already in a mating position, W's N cannot be taken either, otherwise QxR mate.
Maybe it's some fun we can muse ourselves--that Karjakin (among the top 10) allowed such a position (blitz though) in such an early stage, and the opponent is not too well-known (doubt if he's in the top 20 / 30 Elo list.)
Guess the editor wishes to give some candies occasionally (it's only Tuesday!)
|Mar-08-11|| ||BOSTER: Reading many comments in this site you can create the image that chess is collection of many simple rules. But if one from the top players in the world lost the game after 8 moves (even in blitz), maybe chess has something more then such "collection".|
|Mar-08-11|| ||YouRang: It doesn't pay to be lazy. :-(
After a quick glance I settled on 8.Bxe7, without giving serious considerations to other black options besides 8...Qxe7?
8...Bxf2+ -- Doh!
|Mar-08-11|| ||Akavall: I saw the right idea, but I missed 8...0-0.
I was taught [incorrectly] that one can't castle if the King or a Rook is under attack, and I played for a while thinking this was the rule. Until one day I was play a program, and it "cheated" by castling while I was attacking it rook. Perhaps this misconception still haunts me to this day.
|Mar-08-11|| ||patzer2: The threat of mate enables White to win decisive material with 8. Qxd4!, which solves today's Tuesday puzzle.|
|Mar-08-11|| ||MountainMatt: Missed it, but I don't feel too bad. Karjakin missed it too.|
|Mar-08-11|| ||WhiteRook48: ah, of course I played 8 Qxd4|
|Mar-08-11|| ||redorc19: this is similar to the trap in the famous morphy vs. andersson game... the knight on f6 and the bishop on h6 delivering mate is very artistic.|
|Mar-08-11|| ||fm avari viraf: I keep teaching such traps to my students but how come a young GM Karjakin could fall a victim to the kenspeckle 8.Qxd4! & the Black King is in shambles.|
|Mar-08-11|| ||Penguincw: A nice opening trap by Andreikin.|
|Mar-08-11|| ||Penguincw: < Marmot PFL: It had to be blitz (or blindfold) for Karjakin to lose like that. > It was blitz.|
|Mar-08-11|| ||swr: Andreikin discovered a nice trap originally played in 1928: Muller vs NN, 1928|
|Mar-08-11|| ||stefanoleccardi: I got it ! Qxd4 is not so difficult, the king has no escape case !|
|Mar-08-11|| ||gawain: It is astonishing that this should happen to a GM. Even in a blitz game. Wow.|
For the record, I did get this one--unlike yesterday's. The most spectacular available move turns out to be the right move, and it remained only to work out the consequences.
|Mar-08-11|| ||Dr. J: Even earlier: B Blumenfeld vs NN, 1903. Is there earlier still?|
|Mar-08-11|| ||Patriot: <<fm avari viraf>: I keep teaching such traps to my students but how come a young GM Karjakin could fall a victim to the kenspeckle 8.Qxd4! & the Black King is in shambles.>|
How could Kramnik miss a mate in one? Simple...Even the top players are only human.

Yep...it's called being human. But that doesn't detract from the need to have principles/techniques/methods in chess. Top players use them but they still have bad days.
|Mar-08-11|| ||TuxedoKnight: this is almost as awesome as
find everything you need to know at chess
|Mar-08-11|| ||wals: Went for the wrong move, 8.Bxe7.
Black moved the wrong knight to e7.

|Dec-19-18|| ||OrangeTulip: This is also starring in one of the 2 dvdís by Simon Williams on the English. To be advised for positional players who like a setup with c4, Pc3, and g3.|
|Dec-19-18|| ||HeMateMe: I like the pun, terrific imagination.|
|Dec-19-18|| ||thegoodanarchist: Today's pun is based on the title of a movie that won an Oscar for Best Picture.|
And it was possibly the most boring "Best Picture" winner in the history of the Academy Awards.
|Dec-19-18|| ||HeMateMe: it was a complete snooze. I sat through the movie and still don't know what it was about.|
|Dec-19-18|| ||offramp: Well done User: chessbug, today your pun has been chosen.|
Yesterday the GotD pun was supplied by User: chessbug2. No relation, I hope!
<Chessbug2> kibited 8 times to chessgames.com, since 2013.
You, User: chessbug, have kibitzed 12 times in your 12 years as a member.
Keep up the good work!
|Dec-21-18|| ||FSR: <thegoodanarchist> <HeMateMe> Totally agree with your assessments of the movie. Painfully boring. I fell asleep at it, which was much better than watching the thing.|
