  johnlspouge: Tuesday (Easy):

E Vladimirov vs S Zagrebelny, 1988 (37.?)

White to play and win.

Material: B for N. The Black Ka7 has 1 legal move, to a8. The White Qa3 pins Pa6 to Ka7. The White Rb3 opposes the Black battery on the b-file, twice attacked but twice supported, by Qa3 and Pa2. The White Re1 can reload on the b-file. The Black Nf4 has a single flight square, g6. The White Bd2 and Ne3 require activation. The White Ka1 is secured from check.

Candidates (37.): Qxa6+

37.Qxa6+ Kxa6 38.Ra3+ Kb6 39.Ba5+ Ka6 [or Ka7]

40.Bd8+ [or Bc7+] Qa4 41.Rxa4#

Black can interpose with 38…Qa4 29.Rxa4, but only to effect a transposition.

Jun-23-09  Patriot: Initial candidates: Rxb7+,Qxa6+

37.Rxb7+ Qxb7 -- a dead end.

37.Qxa6+ Kxa6 38.Ra3+ Kb6 39.Ba5+ (39.Rb1+?? Kc7 40.Ba5+ Nb6 ) Ka6/Ka7 40.Bc7+/Bd8+ Qa4 41.Rxa4#

Very straightforward.

<TheaN: <Hafen Slawkenbergius: ...there was always a chance after 38...Kb6 that I'll forget what I planned and play 39.Rb1+> Slightly inconsistent if you ask me: with other LESS giving material sacs this might be a possibility, but not with a Queen sac. If I'd play Qxa6† OTB I know I'm going to mate my opponent by forced sequence, whether he plays Kxa6 within a second (why should he think) or after one hour. Aside that I would just not resign as Black because of the beautiful combination my opponent is playing.>

At the class level, I would go ahead and make them prove the win, since 39.Rb1+?? would be an easy blunder to make. At a higher level, the probability of white blundering is much less, but as long as they are human they can blunder.

But I wonder why it was once considered disrespectful not to allow your opponent to checkmate you if a forced mate exists? If anything I would think it more disrespectful to play it out. It's as if they are saying "Do you know how to win this?" rather than "Ok, I know you've got me. I resign!"

  YouRang: Got it. I very pretty mating combo: The pawns take away the light squares, and the bishop takes away the dark, and the king has nowhere to go.
Jun-23-09  Major Dude: Got it. Very pretty.
Jun-23-09  Samagonka: I smell a queen sac...
Jun-23-09  PinnedPiece: Tuesday Goal: 2 Minutes to solve

No contest.

Advertised as "Easy", and so delivered.

  kevin86: Yjr third move was my sticking point,at first I looked to 39 ♖b1+ but then I saw it better to play 39 ♗a5+ sooner rather than later. Black must return to the a-file and mate follows:

37 ♕xa6+ ♔xa6 38 ♖a4+ ♔b6 39 ♗a5+ ♔a file 40 ♗c7+ and mate next

Jun-23-09  tivrfoa: never saw the king move like that

  gawain: I loved this puzzle! After the queen sac and the rook check the follow up Ba5+ is just devastating. And then the bishop finds safe haven (among all those black pieces) after the discovered check while continuing to cover the escape square b6. It's beautiful
Jun-23-09  jfshade: <gawain: I loved this puzzle!> I agree. A beautiful little pattern.
Jun-23-09  StevieB: 2 for 2 so far. A beautiful little combo.

  FSR: Cute - 37.Qxa6+! Kxa6 38.Ra3+ Kb6 (38...Qa4 39.Rxa4+ transposes) 39.Ba5+ Ka-somewhere 40.Bc7+ Qa4 41.Rxa4#
Jun-23-09  hedgeh0g: A nice, easy mate. I might even have spotted this in my games.
Jun-23-09  ounos: Oh, Black was a bit off guard there - what a surprize this must have been! He was under the impression that he neutralised the attack (whatever attack that was it).

Instead of 36. ...Nc8??, 36. ... Qa4 was sufficient to hold comfortably.

Jun-23-09  MiCrooks: Horrible blunder by a player of that caliber. Almost any other moves holds since Qxa6+ Kxa6 Ra3+ fails to Qa4. I assume it was time pressure but it is the kind of threat than could be overlooked, but certainly shouldn't by either of these two players.
Jun-23-09  WhiteRook48: I got only 37 Qxa6+ Kxa6 38 Ra3+ Kb6, then 39 Rb1+?? throwing the win
Jun-23-09  Milesdei: Not hard to see the combination here; very easy though to snatch defeat from the jaws of victory with 39. Rb1. Over the board and smelling blood you have to make sure the kill is clean, lest your prey escape!

  TheBish: E Vladimirov vs S Zagrebelny, 1988

White to play (37.?) "Easy"

It took me a while to find this, considering how "easy" it is! This could possibly pass for a Wednesday problem, but one clue is that there is nothing happening except for directly in front of Black's king: The b-file is well controlled by the rooks, but the weakness is the lonely pawn on a6 protecting the king. Of course, you have to see that the bishop on d2 suddenly springs to life:

37. Qxa6+! Kxa6 38. Ra3+ Kb6 39. Ba5+ Ka6 (or Ka7) 40. Bc7+ (or Bd8+) Qa4 41. Rxa4 mate.

Jun-23-09  lzromeu: Lesson1: be carefull your isolated pawn

36...nc8 or ...nc4 avoid this

Jun-23-09  ToTheKings: <PhilFeeley> Queen sac week?

More like King sac on this one. Black hands white the game. Time pressure blunder perhaps?

Jun-23-09  xrt999: I didn't not get it, not unlike yesterday.
