Jan-03-08  Bobsterman3000: Tiviakov spent half his energy trying to exchange dark-squared bishops, which don't even affect the final mating sequence...
Jan-03-08  Bobsterman3000: Qd6 is a very common line in the Scandinavian, to my knowledge. It's as good as any other line for black in the Scandinavian, for whatever that's worth...
Jan-03-08  A.G. Argent: UdayanOwen, <To be utterly confusing yet still very funny is a good art to master>, Dude, while I agree with the funny part, to say it's utterly confusing is a bit understated, don't you think. Could be it's just what happens to some chess people after too much coffee, what with the fertile, imaginative minds and all but there's also a dash of clinical insanity tossed into that there particular recipe/post. No offense whatsoever, Big Jack, I like it. Don't ever change.
Jan-03-08  drpoundsign: The art of the sacrifice is well demonstrated here.

As a beginner I think I play a sort of semi-Scandinavian by accident when my opening falls apart. lol

Yes, jackmandoo's post was a gem. When I said confusing, I meant confusing for the reader... I'd be interested to see him decipher it for us, because I imagine his metaphors can be unravelled from that wild mind to reveal an actual sensible explanation for his feelings about the game!!

Keep it up Jack

Jan-03-08  be3292: <jackmandoo> if you mean "wooly," I agree with everything you said.
Jan-29-08  aazqua: What's wrong with 9 bc4? I don't see how that isn't game over for black.

  Phony Benoni: <aazqua: What's wrong with 9.Bc4? I don't see how that isn't game over for black.>

Not exactly. Black can actually force the win of a piece after 9.Bc4 Qe4+ 10.Be3 Nxe5 11.dxe5 Qxc4.

White can make it interesting by offering the other bishop with 10.Qe2 Qxf4 11.Nxf7 Rg8 12.Nd6+ Qxd6 13.Bxg8, with rook and pawn for two pieces. But if Black finds that line too speculative, he can just play 10...Qxe2+ 11.Kxe2 Nxe5 or 11...e6.

Mar-02-08  you vs yourself: <UdayanOwen: <jackmandoo:> I have no idea what you are trying to say in your last post but the sheer, outrageous creativity makes it very entertaining nonetheless.>

So the cg.com legend is making a comeback? Very nice!

Mar-02-08  Atking: Where is the opening refutation that I heard from another site? Nothing wrong for Black after simple exchanges 29...Nxd5 30.BxNd5 exBd5 31.Rxd5 Raa8 and 32...Qc6. Tiviakov tried to keep the position complex and lost.
May-18-08  engineerX: <UdayanOwen: Sure 40.Qf6 wins but unless I've missed something, it is nowhere near as good as the game continuation.> You are missing 40.Qf6 Ke8 41.Rg8+ Bf8 42.Bb4 with a forced mate, e.g. 42...Rd6 43.Qxe5+ Re7 44.Rxf8+ Kd7 45.Bf5+ or 42...Qd6 43.Qxe5+ Kd8 44.Rxf8+
May-28-08  Whitehat1963: Friday puzzle after 35...Ra6.
Jan-04-09  larsen959: nobody wrote: 41..Bxa3(forced) 42.d6+!! Kxd6(forced) 43.Bxe5+ and white wins the Queen!
Mar-10-09  blacksburg: over a year later, and as far as i know, 3...Qd6 is still doing OK. or at least i still play it sometimes, but i'm a scrub :(

  FSR: 36.Rxg7+ Kxg7 37.Rg4+ Ng6 (37...Kh8 38.Qf6+ Kh7 39.Qg7#) 38.Bxg6 looks crushing.
Mar-01-18  areknames: <Whitehat1963: Friday puzzle after 35...Ra6.>

Yes, pretty hard for a Thursday. Got the first 3 or 4 moves but couldn't visualize clearly after that. 41.Bg6 is a veritable gem of a final move.

Mar-01-18  SpamIAm: <zb2cr>, methinks that after 38...fxg6 that 39.Qxg6+ is one move faster, e.g. 39...Kf8(h8) 40.Qg8#.

  An Englishman: Good Evening: Pity that White didn't have a Knight at the end of the game--could have written that "A Knight of Ni Melts Defense."
Mar-01-18  agb2002: White has the bishop pair for a bishop and a knight.

Black is about to play f6, reinforcing g7.

Only the black king protects the square g7. Therefore, 36.Rxg7+ Kxg7 (36... Kh8 37.Qf6, followed by Qxh6, wins) 37.Rg4+ Ng6 (37... Kh8 38.Qf6+ Kh7 39.Qg7#) 38.Bxg6:

A) 38... fxg6 39.Qxg6+ Kf(h)8 40.Qg8#.

B) 38... Kf8 39.Bh7

B.1) 39... Rd7 40.Qf6 followed by Rg8#.

B.2) 39... Re8 40.Qf6 as above.

B.3) 39... f6 40.Rg8+ Kf7 41.Qg6#.

C) 38... Kh8 39.Qf6+ Kg8 40.Bxf7+ Kf8(h7) 41.Qg7#.

D) 38... Qd7 39.Bxf7+ Kf(h)8 40.Rg8#.

E) 38... f6 39.Bh7+ Kf8 (39... Kf7 40.Qg6+ Kf8 41.Qg8#; 39... Kh8 40.Rg8#) 40.Rg8+ Kf7 41.Qg6#.

F) 38... Rd7 39.Bh7+ Kf8 (39... Kh8 40.Rg8#) 40.Qf6 as in B.1.

G) 38... Re8 39.Bxf7+ Kf8 (39... Kh8 40.Qf6+ Kh7 41.Qg7#) 40.Rg8+ Ke7 41.Rxe8#.

Mar-01-18  agb2002: I stopped calculation too soon in my line B.1, since after 40... Ke8 41.Rg8+ Black has 41... Bf8. However, 42.Bb4 looks crushing (42... Rxf6 43.Rxf8#).

<An Englishman> Monty Python and the Holy Grail. I had a good laugh.

Mar-01-18  wtpy: I went with 39 Qf6 and while that may not be quite as good as text after 39 ..Ke8 40 Bf5 black is done.
Mar-01-18  AlicesKnight: Saw a lot but missed the pretty point 41.Bg6.
Mar-01-18  5hrsolver: Good analysis <agb2002>

I too went with 40. Qf6

<engineerX> gives a good continuation to 40.Qf6 back in 2008

<engineerX: <UdayanOwen: Sure 40.Qf6 wins but unless I've missed something, it is nowhere near as good as the game continuation.> You are missing 40.Qf6 Ke8 41.Rg8+ Bf8 42.Bb4 with a forced mate, e.g. 42...Rd6 43.Qxe5+ Re7 44.Rxf8+ Kd7 45.Bf5+ or 42...Qd6 43.Qxe5+ Kd8 44.Rxf8+>

<larsen959> Gives the finish to the game line back in 2009

<larsen959: nobody wrote: 41..Bxa3(forced) 42.d6+!! Kxd6(forced) 43.Bxe5+ and white wins the Queen!>

Makes me wonder if black saw this line before he resigned.

Mar-01-18  saturn2: After the distruction Rxg7 black is in trouble.

<36... Kh8 37.Qf6, followed by Qxh6, wins> I would prefer 37 Rg4 because after 37..Bc5 the rook on a6 attacks the queen and defends h6.

Mar-01-18  gofer: I imagine we all got the first couple of moves, but then I went wrong (or at least not the accurate line played)...

<36 Rxg7 ...>

The sacrifice cannot be ignored.

36 ... Kh8?
37 Qf6! Bc5
38 Reg4! Bxf2+
39 Kh1 Ng6 (Rxf6 40 Rg8+ Kh7 41 R4g7#)
40 R7xg6+ Rxf6
41 Rg8+ Kh7
42 R4g7#

<36 ... Kxg7>
<37 Rg4+ Ng6>
<38 Bxg6 Kf8>
<39 Bh7 Rd7!>
<40 Qf6! ...>

Okay, not anywhere as good as <40 Rg8+ Ke7 41 Bg6 mating>, but still pretty strong!

<40 ... Ke8>
<41 Rg8+ Bf8>
<42 Bb4! ...>

Now the mating threats still all exist because Rd7 is blockin any escape for the poor king!


click for larger view

42 ... Re7
43 Rxf8+! Kd7 (Kxf8 Qh8#)
43 Qxe7#

42 ... Rdd6 mate in 10 starting with Qxe5+

42 ... Qd6 mate in 8 starting with Qxe5+

42 ... Rad6 mate in 7 starting with Qxe5+

~~~

I see I am covering old ground, but not alone in mssing the best continuation...
