|Dec-21-09|| ||iamcoolright: Even trivial for a Monday... overworked bishop.|
|Dec-21-09|| ||dzechiel: Black to move (21...?). Black is up a pawn. "Very Easy."|
Very easy it is. The only thing holding the white queen on the board is the white knight (white's g-pawn is pinned by the black rook). After
black captures a piece AND removes the white queen's protection. White does not have time to play 22 cxd4 or 22 Bxd4 or 22 Rxd4 as all of those moves drop the queen via 22...Qxf3. But after
black simply recaptures the queen with
removing the bishop from danger and leaving black now up a knight and a pawn.
White probably resigned after the initial capture. Time to check and see.
|Dec-21-09|| ||Formula7: Got it. 21...Bxd4 wins a piece, for if 22.cxd4 then Qxf3|
|Dec-21-09|| ||patzer2: Today's Monday puzzle solution 21...Bxd4! combines the deflection, overworked piece and pinning tactical motifs in one simple winning move.|
|Dec-21-09|| ||lost in space: 21...Bxd4 and a piece is gone.
White has 4 options:
22. cxd4, Rxd4, Bxd4. The answer is alway Qxf3.
22. Qxf6 Bxf6
I love Monday's
|Dec-21-09|| ||Eduardo Leon: 21...xd4 and the queen is hanging (22.c/xd4 xf3), if 22.xf6 xf6|
|Dec-21-09|| ||mrsaturdaypants: It took me longer than a Monday probably should, but eventually I saw what I take it is the key feature. White's queen seems to be twice protected, but because the g-pawn is all that stands between his king and black's rook, the knight on d4 is actually the only thing preventing black's queen from capturing her counterpart with impunity. So, take the knight.|
None of the three ways to recapture on d4 stop 22 Qxf3, and if instead white plays 22 Qxf6 then 22 Bxf6, and black has won a knight.
Were it later in the week I would stare a while longer, but it's not. Time to check.
|Dec-21-09|| ||patzer2: The obvious losing blunder is 21. Rh4? White avoids immediate disaster with 21. Rxg6 , but still faces a difficult defensive task against a strong Black advantage.|
Earlier, 13. N2b3 appears to be White's last best chance for advantage.
|Dec-21-09|| ||zooter: I was thinking that it was white to move and was looking at this for about a minute and then realized it was black to move|
Then, I got the move in an instant
21...Bxd4 (removing the defender of the queen). Now
22. cxd4/Bxd4 Qxf3 loses outright
22. Qxf6 Bxf6 wins a piece
Time to check
|Dec-21-09|| ||TheBish: Already up a pawn, 21...Bxd4! wins a piece because of the threat of 22...Qxf3 (winning the queen). Done!|
|Dec-21-09|| ||Once: The winning variation has been well explained by mulearned colleagues, so what is left to say?|
Perhaps it is worth looking at how black won. First, he didn't rush to castle. I know all the books say that you should castle early and often (possibly one of the earliest ever chess jokes). But when your king is safely protected by central pawns, as in the french, it can be better to delay castling until you know where you want to park your king.
By contrast, white castles very early and in so doing gives black a juicy target. Black then opens lines against the white king with the oh so fashionable g5. And then he parks his rook on the same file as the white king. If ever I don't know what to do in a quiet position, I look to park my rooks opposite enemy royalty.
Black also centralises his pieces (especially queen and bishiop) and points them at the white kingside.
Does all of this guarantee a win? Nope, it doesn't. The bad news is that it creates endgame weaknesses - against strong opposition that isolated h pawn could turn out to be a liability. And before the endgame you might find yourself the subject of a such a strong counter-attack that you would wish you had castled.
But this plan of black's does create the preconditions for tactics, where the attack on the enemy king can either lead to a mate or help to grab material. All you need to do is to be alive to those tactics when they arise.
And lo it came to pass with 21...Bxd4, exploiting the pin on the g file and the strength of the centralised bishop and queen. It is not so much the tactic that we should memorise as the approach moves which made it possible.
|Dec-21-09|| ||WhenHarryMetSally: black wins a piece. that's about it.|
|Dec-21-09|| ||notyetagm: remove the guard!|
|Dec-21-09|| ||whiteshark: A good start into the wintertime. 1/1|
|Dec-21-09|| ||gofer: I was hoping for my usual Monday morning "Queen Sac" fix... ...but I will have to wait...|
21 ... Bxd4
22 Bxd4/cxd4 Qxf3 winning the queen!
All other alternatives keep the queen, but lose the knight
22 Qxf6 Bxf6 ending up a knight up in the exchange
22 Rh3 Bxf2+ ending up a knight up in the exchange
22 Kf1 Bxf2 ending up a knight up in the exchange
So not exactly earth-shattering... ...Time to check...
|Dec-21-09|| ||TheaN: Monday 21 December 2009
Material: Black up,
Candidates: Qxf3, <[Bxd4]>
White made a well known beginner's mistake, even though it might have been lost otherwise too, by allowing Black to deploy a <retract> defense or whatever wonderful name <notyetagm> used for it; it was something different (maybe it has an official name). Black wins by simply taking out the Queen's defender:
<21....Bxd4> I said defender, because the Queen is only defended by one piece:
<22.cxd4 Qxf3 > because the g2-pawn in pinned. Because the Queens are attacked by each other, White might be able to escape with:
<22.Qxf6> but here is where that <retraction> comes: if Black recaptures with the Knight (more logical than the Rook anyways), cxd4 at least levels piece material. However, the Bishop, coming initially from e5, can retract to f6:
<22....Bxf6 > and Black should be able to win this easily, throwing in Ne5 and O-O-O and White shouldn't hold. Somewhat odd Monday, time to check.
|Dec-21-09|| ||kkshethin: i found it too easy. in fact so easy, i started to look for other options.
Alas if i could find other days same way|
|Dec-21-09|| ||zanshin: A little different for a Monday, but good theme: attack the overworked piece.|
|Dec-21-09|| ||CHESSTTCAMPS: "Fresh start" Monday, after misses on Friday and Sunday.|
Black, on the move, is up a pawn in a position that probably arose from a French Defence. The rook on the g-file pins white's g-pawn that protects white's queen. Therefore, black should remove the only defender of the Q:
This wins a piece, because if cxd4? or Bxd4?, then Qxf3 leaves black a Q ahead. if white chooses to play on a piece down, the best option is 22.Qxc6 Bxc6 23.Rxh7. Most likely, white resigns immediately.
|Dec-21-09|| ||A Karpov Fan: got it|
|Dec-21-09|| ||chrisowen: Sorry for the trash talking but Rh4 is rubbish. If you refused bishop takes then look again. I'd say you lie, bin the night with Bd4 is the suttle choice, pile it in.|
|Dec-21-09|| ||goodevans: I got it quickly enough, but I actually think this is tougher than usual for a Monday. Don't forget Monday is billed as "Very Easy" and is more often than not a Q-sac mate-in-2.|
As <patzer2> puts it: <Today's Monday puzzle solution 21...Bxd4! combines the deflection, overworked piece and pinning tactical motifs ...>. Plenty there for the beginner then! Also, how many bothered to check that the resource 22 Rf4 fails?
|Dec-21-09|| ||Marmot PFL: 21 Rh4?? what a beginner move.|
|Dec-21-09|| ||johnlspouge: Monday (Very Easy)
Gipslis vs Ulibin, 1988 (21...?)
Black to play and win.
Material: Up a P. The White Kg1 has 2 legal moves, both light squares on the back rank. The Black Qf6 and White Qf3 are mutually attacking, burdening the White Nd4 and Pg2. The Black Rg6 pins Pg2. Thus, Black should remove Nd4, removing all defense of Qf3. The rubber band defense between Bd4 and Qf6 then rescues Bd4. The Black Ke8 is secured from check.
Candidates (21...): Bxd4
21…Bxd4 (threatening 22…Qxf3)
22.Qxf6 [else, Black has a tempo to rescue Bd4]
White has lost a N.
|Dec-21-09|| ||CHESSTTCAMPS: <goodevans:>
<Also, how many bothered to check that the resource 22 Rf4 fails?...>
A good point that I and almost everybody else failed to note.
