Sep-06-06  Halldor: Very nice puzzle - got it when I saw that 46.Qg4+ wouldn't work at once.
Sep-06-06  Halldor: Yes, Fritz likes 46...Qg4+, - I however stopped working on it when I saw that 46...Rb4 works.
Sep-06-06  Larsker: Fine puzzle. I'm 3 out of 3 this week until now. The over-my-head ones usually come later in the week.
Sep-06-06  mikejaqua: Got this one quickly, but I missed the pawn headed for e8. Would have been OK in a game as it was easy to catch though. Still it points out the importance of analyzing thoroughly.
Sep-06-06  zb2cr: I agree with a previous poster--this one was easier than yesterday. Saw it in a matter of less than 20 seconds.
Sep-06-06  dakgootje: any one wants to enlighten me what happens after 42. Qxc3? guess something like 42. Rb1 Kf2 43. Qa2 Kf3 44. Rf1 Ke4 where whites king isnt placed on worlds best place, but i think black doesnt have any real threats, right?
Sep-06-06  tino72: <dakgootje> After 42 Qxc3 I think 42...Qa2 wins straight away. White has no checks and I can't see how he can avoid giving up his queen after the coming Rb1.

  YouRang: Funny, I went with 46...Qg4+, but didn't quite have the right line to finish. I like 46...Rb4 better anyway.
Sep-06-06  Scarecrow: I was thinking 46. - Qg4+ 47. Kd3 Qf5+ 48. Kxc3 Qxf6+, much worse than Rc2+, but after the queens are exchanged, black's rook must be able to win the game.

  kevin86: Since the puzzle usually calls for the BEST move, The text move may NOT have been the best move-though it is the easiest. Rybka says (see above) Qg4+ is the best move.

The pin and skewer are quite elegant!

Sep-06-06  uuft: Watch me on mondays! :))
Sep-06-06  dakgootje: <tino72> ah yes, of course, how could i oversee it, thanks
Sep-06-06  RandomVisitor: 46...Rb4 has a simplicity that works, as patzer2 has stated, and perhaps is the best move as far as humans are concerned.
Sep-06-06  GoldenKnight: Thank you Life Master AJ and all the others, including the compters, that picked Qg4+. This would not be the first time I thought my solution was just as good, and in other cases, better than the move made OTB.

  Eggman: From Short vs Vaganian, 1989, a thematically similar (and very pretty) finish, taking place on a diagonal and involving two skewers instead of a pin and skewer:

White to play and win (see White's 51st move).

Sep-06-06  Nostrils: <RandomVisitor>
I have a doubt. The position in the third line of Rybka's analysis;

3. (-6.37): 46...Rb4 47.Qxb4 Qg4+ 48.Kd3 Qxb4 49.e7 Qd6+ 50.Kc2 Qd2+ 51.Kb3 Qxe3 52.Bg5 Qe1 53.a5

isn't clear cut. It is likely the white a pawn and black c pawn will fall off the board together. The black queen can the collect the g3 pawn and white will play h4 leaving an endgame position requiring further analysis. It's not easy to prove this is a win for black.

  Eggman: <<1. It takes longer to find additional decisive solutions, and making this a habit could put you in time trouble in OTB games.>>

Apparently Keres was in the habit of continuing to look for other winning lines even after finding a way to win, and this may have cost him a crack at the title: Keres vs Filip, 1956.

Sep-06-06  jahhaj: <GoldenKnight> I really like your avatar, where did you find it?
Sep-06-06  scorpius: I can't believe I didn't get this one :(
Sep-06-06  LIFE Master AJ: The move actually chosen in the game (46...♖b4) ... is not the most precise. It deserves a question mark, or at least a dubious appellation. There is even a REMOTE possibility, that if White can set up a fortress, (and keep the button on e7); that the game could be drawn.

It is Black to move in this position.

[ Better than the game would have been:
46...♕g4+; 47.♔d5,
This is virtually forced.

< 47.Kd3?! Rd2+; 48.Kxc3 Rc2+; 49.Kxc2 Qxc4+; 50.Kd2 Qxe6; ( ) >

47...♕f5+; 48.♔d6,
Once more, this is close to being forced, other moves are clearly worse.

< After the moves: 48.Be5? Rd2+; 49.Kc6 Qxe5; ( ) the box says that Black's advantage has more than doubled, and after the machine sits for a while, it begins to see the mate coming up on the horizon. >

... and now after
48...♕xf6; ( )
White would probably resign.]

Sep-06-06  greensfield: Looked at rook pin with 46...Rb4 first, so got solution quickly.
Sep-06-06  LIFE Master AJ: The solution - given above - was what I chose. (Although I was not 100% certain that it would work.)

It also fits in with Kotov's idea that the most efficient way to analyze is to examine the most forcing moves first ... and then work your way down the list.

When I saw that Black had actually chosen the ...Rb4 try, I thought maybe there was a hole in my idea, or that I had chosen the wrong move.

I feel vindicated now.

  gawain: I saw... Rb4 very quickly. For some reason these decoys come easily to me. I thought ...Qg4+ would work, too--but there seemed nothing especially clever (i.e. puzzlish) about that line, so I dismissed it.
Sep-06-06  RandomVisitor: <Nostrils>Interesting insight. I frequently fall into the trap of believing my computer when I should in fact use my head.
Sep-11-06  LIFE Master AJ: It was a fun 'partie' ... certainly a nice workout in the analysis field. (Thanks Chess Games!)
