|Jun-03-11|| ||bright1: I think this could be a Monday or Tuesday puzzle with White to play and win on move 16.|
|Jun-27-11|| ||squlpt: Rd8+ removes king's defense of the queen. Only move is 17....Kxd8, 18. Qxf7|
|Jun-27-11|| ||bachbeet: Rd8 for check is the move.|
|Jun-27-11|| ||lost in space: Took me a few more seconds than a usual Monday.
17. Rd8+ Kxd8 (only move)
18. Qxf7 and white is ahead with material.

In addition Black will lose more material (either Ne4 or Bc8) as he can nothing do against Rd1, e.g.
18...Bd7 19. Rd1 and also the Bd7 goes astray.
I love Mondays!
|Jun-27-11|| ||rhickma4: 17.Rd8+ Kxd8 18.Qxc7 Bg4 (to stop Qe7#) 19.Qd4+ wins the N|
|Jun-27-11|| ||VincentL: "Very Easy".
White has sacrificed material, and is down N for P.
I didnīt see this instantaneously, but after short consideration the solution came to me.
17. Rd8+. I imagine black resigend at this point in view of 17......Kxd8 (forced) 18. Qxf7
leaving white with a material advantage of Q + P for R + N (although perhaps this is not
such an elementary win below master level).
Time to check the game and kibitzing.
|Jun-27-11|| ||Phony Benoni: Well, it's Monday, so obviously Black sacrifices his queen and ... er, never mind.|
|Jun-27-11|| ||sevenseaman: I knew <CG> were going to change tack one of these days. |
Whatever time the puzzle took me it was you know due to what. Creatures of habit can be thrown off guard!
A good ploy for a change.
|Jun-27-11|| ||sevenseaman: <PhoneyBenoni> Its a Wimbledon Monday, you cannot spot a winner in a routine manner!|
|Jun-27-11|| ||newzild: One move earlier would have been a better puzzle, maybe for a Tuesday.|
|Jun-27-11|| ||ChessNewbie55: well said, newzild.|
|Jun-27-11|| ||rilkefan: Why is this game in the database at all?|
|Jun-27-11|| ||M.Hassan: "Very Easy" White to play 17.?
White is down by a Knight for a pawn.
White gives one Rook to get the Queen
|Jun-27-11|| ||goodevans: In one respect a little deeper than usual Monday. Whilst the tactic is only two moves deep, the net result leaves a material advantage that isn't completely overwhelming since white has sac'd a piece to get to this position.|
Black resigns because after <17 Rd8+ Kxd8 18 Qxf7> there isn't anyway to stop further loss of material. The threat of Qe7# means he must move his B (since <18 ... Re7> fails to <19 Rd1+>) but there isn't anywhere good to move it. <18 ... Bd7> is met by <19 Rd1>, whilst <18 ... Bg4 19 Qxg7> forks B and R.
|Jun-27-11|| ||dzechiel: White to move (17?). Black has a knight for a pawn. "Very Easy."|
White can pick up the queen for a rook by playing
17 Rd8+ Kxd8 18 Qxf7
and the disorganization of black's pieces should allow white to either pick up more material or checkmate before black has a chance to regroup.
Time to check.
|Jun-27-11|| ||Funology: I guess the main wrinkle here is eschewing Qa4+, which would win the Knight and obtain approximate material equality.|
|Jun-27-11|| ||sevenseaman: A man has been allotted $ 100 to booze up. The barman charges $10 per glass of Whiskey, $3 per glass of wine and $0.50 per glass of beer. May be a rake but to keep the explanations simple to the missus, he wants to make it exactly 100 glasses (assorted).|
How many glasses of each brew to keep both figures to 1oo.
|Jun-27-11|| ||cyclon: 17.Rd8+.|
|Jun-27-11|| ||Once: Now that was very witty of chessgames.com.
We are constantly talking about queen-sac mondays. We get a bit dismissive, a bit blase in a world-weary seen-it-all before kind of way.
So today they throw us a puzzle where the object is to win a queen and not to throw one away.
It's the old old story of boy meets girl, boy falls in love, girl finds someone with a ferrari, boy gets dumped.
Or in this case, queen attacks queen, king defends queen, rook deflects king, queen takes queen. Just another story of love and loss in the mean city.
Rewind a move for each side, and we arrive here:

I guess that CG didn't want to use this for a puzzle because there are too many winning moves. The point is that the black king is stalemated and the Ba3's long range effect means that black can't castle into safety.
Hence 16. Bxf7+ to force 16...Qxf7 as the only legal move. Which in turn sets up today's puzzle. A piece sac (or as Patzer2 would say a pseudo sac) to drag the black queen onto a square where she is protected only by a stalemated king.
Then deflect the king away to win the queen. And then the large female vocalist is doing her solo from the echoey confines of the wooden box.
|Jun-27-11|| ||I play the Fred: I wish I had cooked up some kind of <Super Patzer> sock puppet (like my own play isn't weak enough) who weighs in on every POTD with the worst possible suggestions. Since I didn't, just pretend that I did in the following paragraph:|
<Well, white only has a pawn for the piece and a loose black king here. Can't let black get his extra material organized. Sure, 17 f3 <looks> strong, but black can just give back his extra material with 17...Nd6 followed by 18...0-0. <I've got it!> A rook to e1 <also> threatens the knight, but supports the passed e-pawn! And since the QR is already an active participant in the attack, the killer continuation MUST be <17 Rfe1>. Pretty tough puzzle there.>
|Jun-27-11|| ||jheiner: Very cute CG. After the INSANE Sunday puzzle (and day for me), here I am looking forward to the warm, reassuring Q sac Monday. But oh, CG, you just couldn't give me that warm fuzzy. Had to try to be tricky. Is this an indication of things to come this week? Especially after I had my best CG week ever last week.|
I glance at the puzzle and immediately see Qa4+ winning a N. But one thing CG puzzles teach you is take the few seconds to count up Material before looking at tactical shots. No assumptions. So of course Qa4+ is the patzer move. Another second and Rd8+ wins the Q, that should do it. Cheers.

Wimbledon Monday....I can imagine legendary Dan Maskell exclaiming "Oh, I say!" after 17. Rd8
|Jun-27-11|| ||jheiner: <sevenseasman> Here ya go:|
We have two equations of three variables, plus the knowledge that we can't have negative drinks or fractions of glasses.
Let y be the number of whiskeys.
Let w be the number of wines.
Let b be the number of beers.
The total number of glasses is 100:
100 = y + w + b
The total cost is $100:
$100 = $10y + $3w + $0.5b
Now divide that last one by $0.5:
200 = 20y + 6w + b
And subtract the two equations
200 = 20y + 6w + b
- 100 = y + w + b (first eq.)
100 = 19y + 5w + 0b
or: w = 20 - (19/5)y
Conclude that whiskeys (y) must be factors of 5, and anything more than 5 yields negative wine [and that's bad.]
So y = 5, thus w = 20 - 19 = 1.
There are 100 glasses total, 100 - 5 - 1 means 94 glasses of beer.
Sure enough that works out.
94 bottles of beer [on the wall]
1 glass of [non-negative] wine
5 whiskeys [please]
Now what does 1 bourbon, 1 scotch and 1 beer get you?
|Jun-27-11|| ||gofer: Its very early in the week for a <GOOT> so perhaps we are simply meant to think that the puzzle has been solved. During this exchange we are R for Q up, the King is in a mating net and we can easily swing our Rf1 to d1, if the good old fashioned 19 Qe7# gets blocked. So a more difficult Monday than normal... ...can black stop the mate?|
<17 Rd8+ Kxd8>
<18 Qxf7 ...> <GOOT>
18 ... c5 19 Rd1+ mating
18 ... Nd6 20 Bxd6 cxd6 21 Rd1 Bd7 22 Rxd6 winning
<18 ... Bd7>
<19 Rd1 Nd6>
<20 Bxd6 ...>
Now if black re-captures black loses Bd7! So black cannot recapture!
20 ... Re8 21 Bxc7+! Kxc7 22 Qxc7 Kb6 23 Qd6+ Ka5 24 Qc5+ Ka6 (b5 25 a4! Rab8 26 axb5 mating)
25 a4 b6 26 Qb5+ Kb7 27 Rd7+ Kb8 28 Qc6 mating
<20 ... c6>
<21 e6 ...>
Game Over! After all this I hope that 17 Rd8+ is right otherwise its going to be a long week!
|Jun-27-11|| ||JoergWalter: <sevenseaman>
it is 5 glasses of whiskey, 1 glass of wine and 94 beers. + a terrible hangover for 100 bucks.
