  jahhaj: <witty> Against a rook move along the first rank Black simply plays Bc5 followed by hxg2. White is too constricted to do anything to stop this. If he plays Kxh3 Black has Rxh5, if he plays gxh3 Black has Rg8+, Bxf5, Be7#
Oct-30-05  Dionyseus: White smothered himself by playing 45.Bxh5. Had he taken with the King, he would have had good chances to at least draw the game.

  DWINS: I don't understand 47...Kb6. I guess the idea is to eventually force Bc5 but why not just play it now? After 47...Bc5 48.b4 hxg2 49.Rb1 g1Q+ 50.Rxg1 Bxg1 Black wins easily.

Oct-30-05  sheaf: guys isnt it way too easy for a sunday puzzle
Oct-30-05  Averageguy: I exchanged the Bd7 for the Nf5 before playing h3. Does that also win?
Oct-30-05  erimiro1: Sorry, but like yesterday, I don't call 46. - h3! zugzwang. Compare it to Nimzovitch's 25. -h6! against Samisch (Karlsbad 1923) and see for yourselvs: the h6 move didn't have any value for itself and didn't threat a thing. It "only" locked the enemy pieces and forced Samisch to move. Today's 46. - h6 has a purpose: to prevent the white king from escaping from the net of the 2 bishops and rook.
Oct-30-05  patzer2: Based on IM Silman's definition <Zugzwang: “Compulsion to move.” A German term referring to a situation in which a player would like to do nothing (pass), since any move will damage his game>, today's puzzle solution (46...h3!) does not create a Zugzwang position.

The possibility of not moving wouldn't help White much here. Even if White could legally pass on his 47th move, Black could play 47...Bc5!, threatening the pawn capture 48...hxg3 with an easily won game.

In fact, even in the game continuation, Black's win is a bit easier after <47. c3 Bc5!> 48. g3 (other moves allow 48...hxg3 or 48...Bxf5 followed by 49...hxg3 ) and 48...fxg3! .

Oct-30-05  Lion83: erimiro1: I disagree, I think it could be called zugzwang even if one of the players has some useless waiting moves.

  jahhaj: <Averageguy> After 46...Bxf5+ 47.exf5 h3 I think White can just play 48.Rxh3. There's no threat with Rg8+ anymore because White play Bg6 protected by the pawn on f5.
Oct-30-05  Averageguy: <jahhaj>You are correct, I missed that. I initially thought after 46...h3 white could take the bishop on e7, but I forgot the knight was pinned. My mistake.
Oct-30-05  OsmanAnwar: Does anyone know from where or how i can access all the chess puzzels which are displayed daily on this website???
Oct-30-05  mgracian: "DWINS: I don't understand 47...Kb6. I guess the idea is to eventually force Bc5 but why not just play it now? After 47...Bc5 48.b4 hxg2 49.Rb1 g1Q+ 50.Rxg1 Bxg1 Black wins easily." I Believe that Black did not see the winning move 47...Bc5, the black's idea was to get a passed pawn on the Q-side with the help of King and Bishops.

Oct-30-05  Deep Urkel: This week has been great fun. Every day we can bicker endlessly over what exactly zugzwang means!! Chess players live for that don't they?
Oct-30-05  cuendillar: <OsmanAnwar> There are some game collections listing the daily puzzles.
Oct-30-05  Kola: Hey people. I think the point of Kb6 is to put white in Zugzwang. By eliminating all white's pawn moves on the queen side, white is forced to play something bad of the king side. Notice how white will not be able to play anything but to move his Bishop--leading to mate--or sack his Bishop and Rook, as he did in the game. Capturing the black pawn by any means is not satisfactory either. I think Kb6 is the easiest way to win. Capablanca's style.
Oct-30-05  patzer2: While today's puzzle solution is not technically a zugzwang, the multiple tactics make it a little difficult to classify -- at least until you identify the decisive tactical theme (pawn promotion).

A number of themes are involved in today's 46...h3!! Sunday puzzle solution:

1. It has an element of what Chess Informant once classified as blockade in it's 1980 Encyclopedia of Chess Middle Games, but what is now more commonly referred to as "obstruction." The idea is that if the pawn or Rook capture the renegade pawn with 46...Rxh3 or 46...gxh3, then White Blocks or obstructs his King's escape route and loses the Bishop, which his King is protecting, after 47...Rg8+ 48. Bg6 Rxg6+ .

2. It involves a bit of the "clearance" theme as it frees up the h4 square for a neat mate if White tries to free his Bishop with 47. Bf7??, allowing the following picturesque mate problem:

If 47. Bf7??, what is Black's best (47...?) reply in the diagram above? (Hint: It's mate in one move.)

3. Given the obvious nature of these simple threats, which most club level players would likely avoid, the main idea seems to involve a different tactical theme. The predominant theme being that this untouchable, renegade pawn has now become a decisive "passed pawn." For example the possibility <46...h3> 47. g3 (best per Fritz 8) 47...fxg3 48. Ra1 (48. Kxg3 Bxf5 ) 48...Rxh5! 49. Kxh5 Bxf5 50. exf5 g2 leaves White about to be steamrolled by a pair of connected passed pawns (see diagram below):

Oct-30-05  patzer2: 51...Be8! sets up a neat discovered check in the game continuation.
Oct-30-05  ARTIN: neat puzzle, not hard though
Oct-30-05  patzer2: Note that the winning combination 46...h3! was made possible by the weak 45. Bxh5? (better was 45. Kxh5=) and the blunder 46. Rh1?? (better was 46. Bf7 which saves the Bishop and gives White practical drawing chances).
Oct-30-05  patzer2: <Kola> Although I would not personally agree, you can find some support for calling the position after 47...Kb6 a zugzwang at National Master Dan Heisman's site at http://www.chesscentral.com/novice/..., where he defines <Zugzwang: When you have to move, but any move is bad for you.>

However, note that this based on definitions in Chess as "commonly used," and is not, I suspect, intended to be an accurate definition to use in classifying chess combinations by their primary tactical theme(s).

Oct-30-05  DexterGordon: <patzer2>, I'm not sure I see how your suggested 46. Bf7 (instead of 46. Rh1), helps White after 46...h3.

The only moves I can see to stop the threatened mate at h4 are 47. Bh5 and 47. g3, and in either case White seems to be in the sort of trouble you describe in your earlier posts!

Oct-30-05  patzer2: <DexterGordon> I guess you're right about 46. Bf7 losing to 46...h3! Per Fritz 8, play might continue 46. Bf7 h3 <47. Rxd7+> (staves off the immediate mate, but Black's slow but sure endgame initiative is little consolation for White) 47...Kxd7 48. gxh3 Ra8 49. h4 Ra1 50. h5 Rg1+ 51. Kh3 Rh1+ 52. Kg4 Rh2 53. b3 Rxc2 54. h6 Bf6! (-1.87 @ 14 depth) with a won endgame for Black .

So I'll scratch 46. Bf7 as a saving idea for White, and retract the ?? Blunder annotation for White's 46th move, as 46. Bf7 is apparently just a longer slower torture on the way to defeat. Still that leaves 45. Kxh5= (equal per Fritz 8) as an improvement over 45. Bxh5? (apparently the losing move).
