|May-04-08|| ||Illogic: Wow. Wow. WOW...|
|May-04-08|| ||zenpharaohs: Beautiful position. 41 Qxe7+ jumped out at me, so this puzzle ended up being easy.|
It turns out that White is forced all the way until he can promote; and other than spending time on windmill checks, White is forced until he creates the escape square by taking the rook at f5. This also is a way to see how to solve the puzzle.
That there is exactly one forced line that solves the puzzle is unusual for chessgames puzzles. I often (usually?) end up in alternate lines I like better than the game line.
|May-04-08|| ||zenpharaohs: notyetagm: "This game ends in an -UNBELIEVABLE- tactical display by Inarkiev"|
It's actually pretty believable. It's forced.
|May-04-08|| ||Dilbertarian: Beautiful combination, but not so "insane" since Crafty finds it at once. However, it prefers 45. ... Kf8 46. Rxe8+ Kxe8 47. c8=Q+ Ke7 48. Qxf5.|
|May-04-08|| ||MarkThornton: <bachiller: If I dare risk a pun in English (an exotic language for me) I'd say that we are watching Wilde play, showing the Importance of Being Ernesto.>|
That is a pretty impressive pun!
|May-04-08|| ||zenpharaohs: dzechiel: "True, white could play 41 Rh1 to stay out of the immediate mate"|
No, that gets mated. 41 Qxg4? is the only move other than the solution 41 Qxe7+ which avoids mate.
But 41 Qxg4? still loses when Black pins the queen:
41 Qxg4 Rg5
42 Be6 Ng6
43 Re3 Rxg4+
44 Bxg4 Qh4+
45 Kxf3 Rxe3+
46 Kxe3 Qg5+
47 Kd3 Qxg4
and White is down Queen and Knight to Rook and two pawns, and his promotion threat is gone.
The only way for White to survive is 41 Qxe7+
|May-04-08|| ||Terry McCracken: < parmetd: another nice and easy one. Qxe7. >|
Before you say it's so easy, show some lines and respect to those who did.
It's a fully forced line so show it; Is that asking too much?
|May-04-08|| ||TrueBlue: after very difficult Friday and Saturday, a Sunday with a forced first move :) Very easy.|
|May-04-08|| ||MostlyAverageJoe: I have to agree with <XMarxT3hSpot> and <zenpharaohs> -- this felt like a Friday puzzle. Normally on Sundays I am happy if I get the general idea, so, expecting insanity, I peeked after concluding that after 41.Qxe7+ Kxe7 42.Rd7+ Kf8 43.Rh1 Qxh1 white should be able to queen the pawn. I replayed the rest of the game without peeking at the score as a personal guess-the-move game and it all seemed rather obvious.|
|May-04-08|| ||Laboratory: This was not so insane after all. One can see that black mates with next move, so it must be check all the time.
Qxe7+ (Rook takes looses to promotion.) Kxe7 and it is pretty easy after that.
43.Rh1 was beautiful move.|
|May-04-08|| ||Some call me Tim: The scenarios where one side can force mate in one move are the simplest. Keep checking, or deflect the Q away from the mating square/file. Good combination but not "insane."|
|May-04-08|| ||Samagonka: Insane or not, who cares? It feels sooo goood to solve a Sunday puzzle!|
|May-04-08|| ||whiteshark: Had the erroneous assumption it was a Monday puzzle. :(|
|May-04-08|| ||jon01: I only solved it because I have seen the game before and had it in my "Fabolous Queen Sacrifices" collection.|
|May-04-08|| ||DarthStapler: I got the first two moves|
|May-04-08|| ||znprdx: Well after Saturday's Sunday-like problem yesterday (1473840) we get a Monday problem? QxN+ and the rest is just details - at some critical point I presume White will play Rh1 to stop the mate threat by which time the pawn promotion and mulitiple other threats will force the issue. The only insane thing is why Black hasn't resigned.|
Far more interseting this morning is the Gashimov-Grischuk bloodbath-see:
|May-04-08|| ||tallinn: Normally I do not like to rate a sunday position easy. It is discouraging all those people who manage to solve it. However, this one is obvious and one can find the way for white to play even not knowing that it will be leading to a win. Everything has to be a check or a defense against Qh3#. Rh1 is a beauty but its justification easy to see in the position when it has to be played. The clue to solve this puzzle is to look at every possible move of white that does not loose immediately. There aren't so many.|
I find it much harder to win the final position once the shooting is over (the black defense in the game is not the best). Black will have - although weak - connected passed pawns f3 and g4 with queens on board and white a bishop ahead. Especially the f-pawn has to be taken care of. I hate those queen endgames. It is so easy to make foolish mistakes there.
|May-04-08|| ||number 23 NBer: I didn't look for very long, but 41 Qxe7+ Kxe7 42 Re1+ looked quite strong at first glance (...Kf8 43 Rxe8+ followed by Rd8)|
|May-04-08|| ||rogermorin: After 41.qxe7+ rxe7
how does white win?
|May-04-08|| ||humangraymatter: Who says it is easy? The first move is obvious if you know there is a combination.But the rook sac.from h1 and remaining moves are very difficult and also very beatiful|
|May-04-08|| ||johnlspouge: Sunday (Insane): White to play and win.
Material: B for N. The Black Kf8 is under pressure along diagonals. The White Qb4 pins Ne7 to Kf8, and Ba2 controls the light squares f7 and g8. The White Rd1 and Rd3 form a battery on the open d-file, suggesting that Re8 is overburdened with defense of the back rank and Ne7, particularly because Kf8 has one flight square g7, from which it does not continue its protection of Ne8. The threat c8=Q strengthens the attack on the back rank. On the other hand, Black has a strong counterattack, threatening mate in one with 41…Qh3. Thus, if White is to win, his next move must relieve the mate threat (which costs ruinously) or give check.
Thus, if all you seek in a puzzle is the candidate move, without exact justification, this looks easier than a Monday…
Candidates (41.): Qxe7+
For future reference: once Qb4 is absent, without further perturbations, 41.Rh1 does not dissipate the immediate mate threat:
41.Rh1 Qxh1 (threatening 42…Qg2+ 43.Kh4 Qh3#)
42.Kxg4 Qh5+ 43.Kg3 Qg5+ 44.Kh3 [Kh2 Qg2#]
44...Qg2+ 45.Kh4 Rf4+ 46.Kh5 Qg5#
To analyze the candidate,
41.Qxe7+ Rxe7 42.c8=Q+
Here or later, …Qd8 loses by surrendering the mate threat. Black has 2 feasible options: (1) interposition with 42…Rd8 and (2) flight with 42…Kg7.
(1) 42…Re8 43.Qxe8+ Kxe8 [Qxe8 44.Rd8] 44.Rd8+ Ke7 45.Rd7#
(2) 42…Kg7 43.Rh1 (threatening 44.Rxh5 45.Rxf5)
In the absence of loss of material, perpetual check, stalemate, or mate, White can now rely on material superiority to win. White threatens
45.Qxg4+ K to h-file [Kf8 46.Qg8#] 46.Qh4+
Under continued checks, White removes Pg4 and Pf3 with Kg3 and then moves Kg3 to g4 and Rd3 to g3, to terminate the checks with the threat Kh5+ if necessary. Once the initiative passes to White, the material superiority should win.
After the forced 41.Qxe7+, I was blind to the game response 41...Kxe7, which superficial computer analysis declares best. I checked a lot of lines after 41...Rxe7 that did not work for White, and because the computer follows my lines for a while after 41...Rxe7, my post probably contains something worthwhile. I will report back after further computer analysis.
|May-04-08|| ||johnlspouge: Analysis assisted by Toga II 1.3.1 indicates that given the candidate 41.Qxe7, the game defense 41…Kxe7 is essentially confluent with the defense 41…Rxe7 I explored.|
41…Kxe7 42.Rd7+ Kf8 43.Rh1
relieving the mate threat and threatening 44.Rxh5.
44…Qxh1 45.Rf7+ Kg8 46.Re7+ Kf8
[Otherwise, the game line occurs:
46…Kh8 47.Rxe8+ Kh7 [now or later] 48.Rh8+ Kxh8 49.c8=Q+
then 50.Qg8+ 51.Qh8+ 52.Qxh1]
[else, transposition into 46…Kh8 above occurs]
48.c8=Q+ K moves 43.Qxf5
essentially transposing into the lines for 41…Rxe7 I gave, after after 44.Qxf5.
This "insane" Sunday puzzle was unusually tight in its variations.

Agreed. If a puzzle is just its first move, today was completely superficial. And likewise, Henry James' "Turn of the Screw" would be just a ghost story... (see http://en.wikipedia.org/wiki/The_Tu..., particularly the section "Literary significance & criticism").
|May-04-08|| ||A.G. Argent: <humangraymatter: Who says it is easy? The first move is obvious if you know...> Hear, hear. Sure, 41.Qxe7+ is, as D. Zechiel says, almost forced because Inarkiev is one move shy of death but the ensuing combination is indeed beautiful. And I love how sometimes it's the quiet moves in chess that can loom deadly as many as 30 moves later ie. 20.Ba2. Bit helpful, that.|
|May-04-08|| ||Billy Vaughan: Beautiful!|
