  whiteshark: epi-morphysm
Jan-17-12  KingV93: Saw this pretty quickly. The d6♙ is unstoppable whith the Black ♘ out of position to guard d8 and d4 covered by the rook to eliminate any checks.
Jan-17-12  SamAtoms1980: 32.d7 scores. After 32....Rxc1 33.d8=Q+ Qf8 34.Qxf8+ Kxf8 35.Rxc1, holy smokes, White is up a rook. 32....Rd8 33.Bc7 also wins.

The text line 32.Qxc8+ is better hidden but allows White's passed pawn to turn into a two-headed hydra.

  morfishine: <32.Qxc8+> wins for White

After <32...Nxc8 33.d7> Black can't stop the pawn from Queening.

The attempt to limit the damage, get out of of way of Whites terrible DSB and preserve a little honor with <33...Rc2> is flattened with <34.Qd8+ Qf8 35.Rfe1>

Of course, an immediate <33...Re2> is met by <33.dxc8+ Qf8 34.Rd8>.

There is simply no hope for Black in this position

  agb2002: White has a bishop for a knight.

Black threatens 32... Rxc1.

The advanced passed pawn invitews to play 32.Qxc8+, destroying the defense, 32... Nxc8 33.d7 and the double threat 34.dxc8=Q+ and 34.d8=Q+ decides the game.

Jan-17-12  gofer: All pretty obvious today...

<32 Qxc8+ ...>

32 ... Qf8 33 Qxf8+ Kxf8 34 d7 Nxd7 35 Rxd7 winning easily

<32 ... Nxc8>
<33 d7 ...>

33 ... Rxg7+ 34 Kxg7 Qb7+ 35 Kg3 Qc3+ 36 Rf3 winning easily

<33 ... Qf8>
<34 d8=Q ...>

White is threatening Bh6 mating, so black has no time to rescue its knight

<34 ... Qxd8>
<35 Rxd8+ Kg7>
<36 Be5+ f6>
<37 Bxb7> winning easily.

===

But I have one question...

What was so wrong with <12 ... Bxe5>?

Jan-17-12  polarx: I thought 32.d7 wins. And it does but I cannot claim any credit since it did not cross my mind at all that after 32...Rd8 33.Bc7 Black could take my pawn! Must go see the eye doctor.
Jan-17-12  zb2cr: 32. Qxc8+, Nxc8; 33. d7! and Black can't protect the back rank and keep his material advantage.

  Once: <gofer> Couldn't see it myself, but Fritz says that 12...Bxe5 doesn't work for black. The problem seems to be that after 13. Nxe5 white is going to get a chance to play Qf3 at some point with a lot of pressure against f7. But it's pretty complicated stuff.

Play might go 12...Bxe5 13. Nxe5 Rxe5 14. Bf4

Fritz says that this is +1.5 even though white is still a pawn down. The line he wants to go into is 14...a6 abandoning the Re5 to its fate. On just about everything else white plays Qf3 with enormous threats.

By contrast 12...a6 avoids all this and Fritz says it is black's best choice. The eval is more or less even at +0.22.

Jan-17-12  chegado: 32.Qxc8 Nxc8 33.d7

Easy indeed, just a warm-up

Jan-17-12  Rosbach: Qxc8+ and d7 are both winning.
10...a6 looks better for Black as it would remove the pin of the Knight at d7 and removes the attacking potential for White. 10...a6. 11. Ba4 b5 12. Bb3 Bb7 13. e5 dxe5 14. fxe5 Nxe5 15. Nxe5 Bxe5.
Jan-17-12  sevenseaman: Find out how logical is your approach to a chess situation.

No solution is sought. Just give White's next best move.

There can be no ambiguity. If you care to consult there is only one that the engines will support.

White to move.

Jan-17-12  VincentL: "Easy".

If the solution is 32. Qxc8+ Nxc8 33. d7 then I solved this instantly.

After 33....Qf8 34. d8=Q+ and white will emerge a rook ahead.

Other defenses (e.g. 32....Qf8) simply lose the rook.

I donīt think I am missing anything. Letīs check.

Jan-17-12  CHESSTTCAMPS: Although white is only up a minor exchange in material, most tournament players would recognize immediately that the advanced, protected passed d-pawn confers a winning advantage for white. The most efficient win is the most forcing, a familiar promotion trick: 32.Qxc8+! Nxc8 33.d7 Qf8 34.d8=Q winning a rook. More laborious and tricky is 32.d7? Rd8 33.Qc7 Qf8! (Qf6 34.Be5) 34.Bg5 Rxd7 35.Rxd7 Nxd7 36.Qxd7 Rxa2 (Qc5+ 37.Kh1 Qxg5? 38.Qxf7+) 37.Rc1 winning.
Jan-17-12  polarx: Sevenseaman, I checked 1.Bxd5 Qxd5 2.axb7 Rxb7 3.Rxb7 and thought there was nothing wrong. I play it on the chess engine and black plays Nf3+ forking king and rook, something which I remember considering just remotely without really seeing it. My brain is not working this morning.

After 3...Nf3+ 4.Kf1 Nxh4 and if 5.Bxh4 Qh1+ 6.Ke2 Bh5+

Jan-17-12  gofer: Thanks <Once>...

  kevin86: White will gain the queen again and end a rook ahead.

  Gilmoy: I saw a slightly longer line that I haven't seen mentioned yet.

<32.Qxc8 Nxc8 33.d7> If Black can just stop (both) queenings, then this capture-chain trades Q+P for R+N, which is actually probably losing. Hence, Black can afford to just return the N.

<33..Qf8[] 34.Bh6> Whitmoy sees that too, and goes straight for mate. Now Black's Q is overworked: she must concede a free Q or <weak back rank>, both fatal. Let us anti-grub the non-material-loss: <34..Qd8 35.Rfe1>:


click for larger view

Black has only one spite-check and a spite-block (Ne7 or Nd6) before he must move his f-pawn for luft.

The prettiest line even doesn't-capture Black's Q <and> drops the d7-pawn, because <two tempi are more valuable than two queens>: 35..Ne7 36.Rxe7 f5 37.Re8+ Kf7[] 38.Rde1 Qxd7?? 39.Rf8#:


click for larger view

(Edit: Yah, I see that <38..Rb8> spoils everything, <39.Rxd8 Rxd8 40.Rd1 Ke6> and White eventually grinds out the B-vs-P endgame. Ergo, we prove that sometimes <grubbing material is the appropriate response> -- 1 in "9")

Jan-17-12  LIFE Master AJ:

White to move, 32. ('?')

Before I studied the aspects of each piece, I might have had trouble with this one. However, a Knight is extremely vulnerable when its on the edge of the board. It has a hard time stopping "Rook Pawns" ... it has even more trouble when its confined to the first row and attacked by an enemy Pawn.

The solution is 32.QxR/c8+!, NxQ/c8; 33.d7,


click for larger view

Black cannot prevent White from getting a new baby girl, and (thus) will be a Rook down. Please note the awkward position of Black's pieces and his complete inability to sufficiently protect his back rank.

Jan-17-12  Dr. J: <Gilmoy> If 32 Qxc8+ Nxc8 33 d7 Qf8 then simply 34 d8/Q. There is no reason to complicate further.

Jan-17-12  Patriot: 32.Qxc8+ Nxc8 33.d7 works nicely.

<morfishine> <The attempt to limit the damage, get out of of way of Whites terrible DSB and preserve a little honor with <33...Rc2> is flattened with <34.Qd8+ Qf8 35.Rfe1>> That should wrap it up. Here's another idea to rub salt in the wound after 33...Rc2 34.d8=Q+ Qf8 35.Bh6!

  Diademas: And once again I sit here, baffled on the buss on my way home. I know, to the best of my abilities, that I have produced stellar work for my employer. Still that is not enough. Its a tuesday, a day I normally should have no problems with. Still there is this nagging doubt in my mind.

I know I didnt hit it heads on, but maybe, just maybe I can still stand tall among my peers,

And yes! No refutation of my line. No 1400 players giggeling on my lame suggestion. My hands stop shaking. I will live another day.
