Sep-17-12  TheTamale: Here was my prize-winning hypothesis:

27) RxN P(either)xR
28) QxR

WHITE WINS A KNIGHT!!

On a Monday no less. Time to hang 'em up.

  Oxspawn: Oh good, Monday, an excellent morning's work and I can join the chase. Black has an exposed king poorly protected by his queen on the wrong side of the action. White has a sharp eyed pawn guarding two key squares on the sixth rank. The only obstacle to white doubled rooks is the black knight which is trying to do two jobs. So… 27. Qxf7 Nxf7
28. Re8+ Kc7
29. R(e1)e7++
Nice how the white pawn (with a nominal value of one) prevents the escape while the black queen (with a nominal value of nine) just gets in the way. What if black does not accept the queen sacrifice?
27. Qxf7 Qxe3
28 Qxf6+ Kc7
29. Rxe3

...leaves white the exchange (rook for queen) and two pawns up and an attack that black cannot stem. The rook seems to have nowhere to go. The king cannot go to b7 because of the knight fork on b5, and cannot go to b6 because Qd8+ drives the king to b7. At the very least the white queen will gobble up the pawns g6 and on a7 and white can also seek to swap off the rooks. If black plays Nd7, then white can play Re7 pinning the knight and preparing for the queen to go to f8 and then take the knight. I don’t see my way all the way to mate, but black would clearly have to resign or be hacked to pieces. Not sure if I get a point or a credit but I think I will get a sandwich and walk the dog. But first I will check that it is indeed Monday not Blunday.

Sep-17-12  dufferps: Yes, black can stave off the checkmate a bit by not accepting the queen sac, but it is a losing cause. I found the longest holdout was when black moved his king 27.... Kc8, to get to a point where his queen could interpose. However, that still could not avoid checkmate, and that variation probably included some inefficient moves by white.
Sep-17-12  Abdel Irada: <The Tamale>: I addressed that "alternative solution" in my second post:

27. ♖xe5?, ♖xg7
28. ♖e8†, ♔c7/♔d7

White is down a queen for a knight, and there is no mate because the black rook on g7 controls the seventh rank.

  gawain: This puzzle manages to combine two common Chessgames early-week themes: sacrifice the queen *and* find a back-rank mate
Sep-17-12  Abulherar: White's best move is:27.Qxf7!
27...Nxf7 28.Re8+ Kd7 (or:28...Kc7) 29.R1e7#
or white will have a rook up.

  kevin86: The queen sac allows the rooks to steamroll and mate on the back two rows. Black cannot interpose and has no escape.
Sep-17-12  sushijunkie: After bombing half of last week, we'll see if this uber-easy Monday will lead into a better scoring week. They seldom do... ;)

But this one took all of zero seconds. And without coffee, even.

  chrisowen: Every xf7 mph see it now counts, fortunate am in crow truck it do gg in passing beck an call 27.Qxf7 Nxf7 28.Re8+ king jog in (d7 or c7 he stir in couple spades) courage too rooks evermore sack queen.
Sep-17-12  PhilFeeley: Mondays seem to always be a queen sac, so that's what I look for now. It seems to work most of the time.
Sep-17-12  PhilFeeley: I just noticed - "World U26". When did we ever need such an arbitrary tournament?
Sep-17-12  Crispy Seagull: 25... Kd8?? Can anyone explain what the heck that might have been about? I know White's got a couple rooks aiming at his face but he abandons the rook...

  Once: My wife says I can't multitask. I think that's really unfair. I have been known to watch TV and drink a beer at the same time.

And I know at least a dozen jokes that are both racist and sexist. I can drive and simultaneously spot a female jogger's independent suspension. Not to mention speaking to the mother in law on the phone whilst beating spider solitaire on the hardest setting. Oh yes, I've got this multitasking thing to a fine art.

But the black Ne5 can't close the e file and defend the Rf7 at the same time. No way, Jose. That's like roller-skating once a month. Only women can do it because it's more multi-tasking than a male or a mule can possibly manage.

Sep-17-12  RookFile: Crispy: Probably just time trouble. He sees that Qxg6+ is possible if he does nothing. He wanted to unpin the knight, and overlooked a tactical flaw.

  Once: I showed this position to the best boy in the world and we came up with an alternative solution. Not as good, but fun all the same: 27. Qg8+

Now 27...Kc7 and 27...Kd7 walks into 28. Rxe5 and white picks up a knight (and retains a strong attack). So black is forced to play the horrible 27...Ke7 28. Qxg6

And black is in a world of hurt. Okay, so he's only lost a prawn but that e file pin and passed h pawn look deadly.

<crispy> 25...Kd8 is actually Fritzie's second choice, only just behind 25...g5. The losing move seems to be 25...Rf7. Instead, 25...Re8 seems better ... according to the silicon monster.

  agb2002: White is a pawn ahead.

Black threatens 27... Rxg7.

The black king has only two ranks to move, White's rooks would deliver mate if the rook on f7 disappeared and the knight were diverted conveniently. Hence, 27.Qxf7:

A) 27... Nxf7 28.Re8+ and mate next.

B) 27... Qxe3 28.Qxf6+ and 29.Rxe3 wins.

Sep-17-12  TheTamale: <Abdel Irada: <The Tamale>: I addressed that "alternative solution" in my second post...>

Ah, so you did. Massive misfiring of neurons this morning. I can't even defer to my usual "no coffee" defense, because in this case I had already drunk plenty. Sigh...

Sep-17-12  rapidcitychess: Queen sac Monday, the day everyone loves.
Sep-17-12  PinnedPiece: My usual Monday goal: solve in 30 seconds.

It took 25 seconds to finally see that an open e-file led directly to mate with my doubled rooks (wow are they useful!) due to little old d5 pawn. So free Rook on f7.

...so at 30 seconds went with QxR expecting black to concede. But the Czecho Jirovsky is Honorable folk. Play to checko-mated.

My Result: Succeed. If there is a Monday fail in my future, I'll know this old brain is diving.

Sep-17-12  1stboard: Blacks 14th move should have been O-O .........
Sep-17-12  Schach and Awe: Another Q sac Monday ... staff need to improve their imaginations, and get beyond obvious Q sacs virtually ever Monday.

  FSR: <Schach and Awe: Another Q sac Monday ... staff need to improve their imaginations, and get beyond obvious Q sacs virtually ever Monday.>

I agree. I understand that CG.com wants to make Monday easy, but many (indeed most) simple tactics don't involve queen sacs. 31.? in F Rhine vs G S DeFotis, 1988 is one of thousands of examples that could be adduced.

  Tiggler: <FSR> and <Schach and Awe> ..But if not Monday, when? I wanted to ask, until I remembered that we had Q sac on c4 twice last week, and neither of them was Monday. (Or did we have Q-sac on Monday also?)
Sep-17-12  QueenMe: Got this one while the JavaScript engine was still firing up. Black can't recapture the Queen after 27. ♕xf7, because then the rooks come downtown and mate the king. The pawn at d5 prevents the King's escape. Yet even if the King could escape, I allege white could still win: his next move will recover the knight at f7, and will definitely capture at least one of the pawns on the f or g files, for Black's own pawn on c6 prevents any of his pieces from offering any assistance. That alone equalizes material, and puts white well on his way to getting his queen back rather quickly.
Sep-17-12  TheBish: Motylev vs P Jirovsky, 1998

White to play (27.?) "Very Easy"

27. Qxf7! followed by mate in two with the rooks, if the queen is captured.
