Sep-27-05  pantlko: <aginis>: <call me crazy but 34.Qb3?? Rxf4 and white must defend f2>

BUT at the cost of queen 35 Qc5!!!!

Sep-27-05  The beginner: <Aginis>

34 Qb3 ..Rxf4
35 Rxg8+ ..Kxg8
36 Qxe6+

Sep-27-05  The beginner: The solution for todays puzzle is

34 Bxc4 as it leads to a mate no matter what black try.

I think the reason why the whole combination is posibel is becasue of the Bishop on f4, covering c1. The black Queen is dying to goto c1 and give a check, and proberly mate with cooperration from the bishop on square c6. But it cant come there from eather square a3, or c4, because the bishop on square f4 is guarding c1.

34 Qb3 wins a piece, not bad, but when there is a mate on the board why setle for a piece :)

Sep-27-05  jcr2001: lol! of course! i tried thinking 34.Bxc4 Qxa3 35.Rxg8+ Kxg8 Bxe6+ and i was stuck...

  benveniste: Another in the neverending "why I can't play this game" series. Within a few seconds, I saw that white's queen was safe after 34. ♗xc4. Then I spent minutes looking for something better, as 34. ... ♕xc4, 35. ♕f8 fell squarely in my mind's blind spot. Eventually, I decided winning the exchange with ♗xc4 was good enough.

Excuse me while I pound my head against the wall.

Sep-27-05  chessic eric: <pantlko> if 34.Qb3,Rxf4 35.Qc5 is not possible, let alone worthy of four exclams.

The line after 34...,Rxf4 supplied by <RAVCT> is the only refutation of 34...,Rxf4. After 35.Rxg8+,Kxg8 36.Qxe6+ black has the equally awful prospects of either 36...,Kg8 37.Qc8+ and black can interpose twice before the curtain falls, or 36...,Kf8 37.Qf7#.

Sep-27-05  chessic eric: oh, and <aginis>, for the first time ever in all the postings I've seen from you, you're crazy.
Sep-27-05  aginis: <chess eric>lol not the first not the last. i didn't stop to think about it very long, which usually gets me into trouble. Thanks to <RACVT> and <the beginner> for pointing out my error.
Sep-27-05  panthercat: Hmm...after:

34. Qb3 Rxf4
35. Rxg8+ Kxg8
36. Qxe6+ Kf8
37. Qc8+ Be8

How does white continue? Admittedly, I haven't looked too deeply at this line yet...

Sep-27-05  YouRang: I got it, but it took a couple minutes. I saw 34 Bxc4 early on, but dismissed it as "just winning the exchange".

I could see that I had to take advantage of the sorry state of the black king and knight, and I couldn't find a good way for the queen or the f4 bishop to help.

At last I reconsidered 34. Bxc4!, and found that Black's pieces are all curiously out of position to prevent a mating attack!

Sep-27-05  The beginner: <panthercat>

37 Qf7 mate

Sep-27-05  beenthere240: <panthercat>
36..... Kf8
37.Qf7 #
Sep-27-05  zb2cr: Saw it after about 60 seconds' thought. Now whether I would have the nerve to even look at a passive Queen sacrifice in one of my own games is a different story. I'd probably look at 34. Bxc4 and think, "Oh, I can't play that...it hangs my Queen."
Sep-27-05  panthercat: <37...Kf8>

Oh yeah...duh...my bad. :)

Sep-27-05  yoozum: Yeah, I saw this one immediately, but it's still a cool puzzle.
Sep-27-05  EmperorAtahualpa: <aginis: call me crazy but 34.Qb3?? Rxf4 and white must defend f2>

Well <aginis>, I wouldn't call you crazy but after your suggestion 34...Rxf3 follows 35.Rxg8+ Kxg8 36.Qxe6+ Kf8 37.Qf7#

  kevin86: I'm like the philosopher cowboy who said:I think therefore I ride. I was putting DeCartes before the horse.

I tried the sac at g8 with or without the queen sac-and it didn't work. The right way or course was the queen sac followed by the inescapable mate threat at g8! OOPS!!

Sep-27-05  EmperorAtahualpa: <pantlko> Not 35.Qc5 but 35.Rxg8+! Check the message I wrote to <aginis>...
Sep-27-05  Philidor: Easy one today. And by the way <kevin86>, it's Descartes. ;-)
Sep-27-05  avidfan: 30...Rxb4 was bad because it was needed for defence of the back rank. White fittingly punishes the rook by pinning it to the Queen. Black worsens the situation by trading off the last rook defender on the back rank. The White rook now dominates the position with a crippling pin on the Black knight. 30...Qxb4 was better.

Even 34...Qe7 would let Black hold on longer with 35...Qh4 threatening 36...Qh1#.

Sep-27-05  fgh: Easy just as yesterday.
Sep-27-05  MaxxLange: <avidfan>: 34...Qe7 35. Qxe7 wins the black Queen for nothing, with mate to follow
Sep-27-05  EmperorAtahualpa: <Philidor> I was thinking the same, but I think <kevin86> misspelled it on purpose to stress the "cart" in Descartes.
Sep-27-05  Halldor: Black's eight rank is badly defendet and his queen is overloaded, and the king in zugzwang. I found the solution, but it took me far too long time (according to the posts here I must be the slowest here).

  patzer2: Black's attempt to win a pawn with the discovered attack 34...Rxc4?! is short circuited by White's winning counter attack and pin on the weakened back rank following 35. Bxc4!

This move (35. Bxc4!) makes a pseudo sacrfice of the Queen in exchange for a mating attack.
