 | | agb2002: Black is a pawn down.
The white queen looks in danger but she still has c5 to move (18... Be6 19.Qxb7). Instead of trying to exploit the position of the white queen, Black can trade his queen for some white pieces with 18... Qxc3 19.Bxc3 Nxe2+ 20.Kh1 Nxc3: A) 21.Qb3 Nxb1 with the double threat 22... Nd2 and 22... f3. B) 21.Qd6 Nxb1 looks bad for White, for example, 22.gxf4 exf4 23.f3 Nd2 24.Rg1 (24.Rf2 Ra1) 24... Ra6 25.Qe7 Ng3+ 26.hxg3 Rh6+ 27.Bh3 Rxh3+ 28.Kg2 Rxg3+ 29.Kh2 Rxg1 30.Kxg1 Nxf3+ 31.Nxf3 gxf3 - + [R+2B+2P]. |
|
| Oct-20-12 | | Zatrikion: I would go with:
18..Qxc3
19.Bxc3 Nxe2+
20.Kh1 Nxc3 (forking Q and R)
21.Qb3 Nxb1
22.Qxb1 f3 (B is trapped and lost, so White can get the pawn back)
23.Bxf3 gxf3 0-1 (this can lead to a winning ending game for Black)
Q vs R+B+N |
|
| Oct-20-12 | | TrollKing: What a gorgeous combination! Very well played. |
|
| Oct-20-12 | | SmyslovTheSlayer: One thing to note is that Qxb1 is best because otherwise Nd2 will fork the Queen and the Rook. |
|
| Oct-20-12 | | tivrfoa: very nice attack. nice combo |
|
| Oct-20-12 | | tivrfoa: Queen sacrifices like this are very instructive. It shows that you need to open your mind. The queen is precious, but minor pieces combined are very strong. |

I saw the game forcing sequence as far as 22.Qb1 and stopped there not seeing a follow-up. Like <Morf> I then started to analyse the Rook sacrifice 18...Ra3 19.Nb5 Nxe2+ 20.Kh1 to reach

with Black to play and lose a Rook. I couldn't work out a convincing follow-up from the original puzzle position - Black needs to move his Q to a forceful square - but the right move is easier to spot from the second diagram. You might like to solve it as a second puzzle. The ever-helpful Fritz put me out of my misery and Black can indeed win from the second diagram. I can post this sub-solution on request unless someone else gives it. I don't feel too bad about missing the (much better) game continuation: I note that it was a Sunday puzzle back in 2004. Good posts from the regulars! |

| Oct-20-12 | | gofer: I have a question, is the following position a win, lose or draw for
black?
click for larger viewBlack can trade its Queen for Rook + 2 Bishops as Bg2 is lost, now is
this good or bad? Is this the line we are meant to find or a red herring? I don't hate this position for black but is it winning? I have no idea.
Unfortunately today I have no time to look at this in detail as I have work
to do and in my head this is the only thing that immediately springs to mind... :-)
~~~
Okay, so I got the first five moves right, which on a Saturday is normally
a huge step in the direction of smug self-satisfaction, but I feel like I
am only half way there, too lazy to do the work, even with a suitable excuse. I certainly didn't see that Ra1 was coming, but having see it and Bh3 it all
looks fab for black!
Half a point to day... |

 | | paulalbert: Like many others I saw the 18...Qxc3 idea and the followup all the way to 22... f3 , but wasn't convinced it was a clear win ( too far for me to visualize concretely beyond that although I saw the possible idea of supporting Ra8 to Ra1 by opening diagonal for Bg7 ), so spent time looking for some other ideas after 19 ... Ne2ch to force something else with a king side attack, but nothing there that I could see, so gave up in frustration. At least my instincts were correct. |
|
| Oct-20-12 | | pericles of athens: wow what a fantastic game! i usually don't even look at the saturday/sunday puzzles because they're far beyond my playing ability, but i'm glad i looked today. bigtime kudos to those of you who solved the puzzle today - that's awesome! |

 | | kevin86: great combo! |

| Oct-20-12 | | pmukerji: Geez...that blew me away...this is why i love this game! |

| Oct-20-12 | | Abulherar: The ♕ sac (18...♕xc3!) looks very cool and funny
to me because:19.♗xc3 ♘xe2+ 20.♔h1 ♘xc3
21.♕b3 ♘xb1 22.♕xb1 f3....
Now,i think that black has better material and position.
It's probably the most beautiful ♕ sac I've ever seen :D |
|
| Oct-20-12 | | James D Flynn: Black has sacrificed a pawn for his attack on the K-side, the material is otherwise equal.
First thoughts: the K looks vulnerable to a N check on e2. If Black can force 18…f3 19.exf3 gxf3 20.Bh1 but now the f3 pawn is attacked 3 times Q, B, N and defended twice R and N. What piece could be diverted? The Q is the obvious candidate . Let’s try 18….f3 19.exf3 Be6(not Rd8 which removes a defender of f3) 20. Qe4(to stay on the long diagonal) Nf6 wins the Q but this doesn’t work because 20.Qc5 prevents Qxc3. Alright what about the immediate 18….Qxc3? It maybe he doesn’t force mate but gets more than enough wood for his Q. 18….Qxc3 19.Bxc3 Nxe2+ 20. Kh1 Nxc3 21.Qb3 Nxb1 22.Qxb1 (Black has R,B, and pawn for his Q now f3 wins a piece) f3 23.Bxf3 gxf3 .
OK now Black has R and 2 Bs for his Q and threatens Bh3(may be 23.Bh3 or waiting for 23…..fxg2 would be better) winning the exchange. White can save the exchange by 24.Nc2(incidentally stopping ideas like e4 followed by Ra1) Bh3 25.Re1 Bg2+ 26.Kg1 (Oh for a N check on e2 now) What if 18.Qxc3 Bxc3 19.Be6 no White could simply play Bxd4,
18…..Be6 19.Qc5 Qxc5 20.bxc5 f3 21.exf3 gxf3 22.Bh1 (now we have the desired configuration but the pesky N is still guarding e2) Nxe2+ 23.Nxe2 fxe2 24.Bxb7 Rab8 25.Be4 exf1=Q+ 26.Kxf1 and Black has a R for 2 pawns but the White Q has options other than c5. 19.Qxb7 Qxc3 20.Bxc3 Nxe2+ 21.K h1 Nxc3 22.Rb2 f3 23.Bxf3 gxf3 24.Nc2 Bh3 25.Re1 Bg2+ 26.Kg1 Ne2+ 27.Rxe2 fxe2 28 Kxg2 e1=Q and Black is up R and B, but 23.Nc2(clearly better ) fxg2+ 24.Kxg2 Bd5+ 25.Qxd5 Nxd5 and Black is a B and N up.
Now for the game. |

| Oct-20-12 | | BlackSheep: Magnifique . |
|
| Oct-20-12 | | holly does hollywood: I'm glad i saw black moves included 24... Bh3, but then i did not know what to do. I feel i did not entirely succeed this POTD because I totally missed the a1-h8 diagonal and 27... e4 ! Would definitely not see all these moves OTB, but pretty combination by Adamski ! |
|
| Oct-20-12 | | Robin Gitte: Wonderful puzzle, CG. I can only look on in awe as events unfold. |
|
| Oct-20-12 | | James D Flynn: Chessgames, I don't speak Czech but I know enough Serbo-Croat to say that "i crni dobiva!" means "and Black is better" |
|
| Oct-20-12 | | Abdel Irada: <King Sacrificer: <Phony Benoni: The bishop moves to h1... WAIT A MINUTE! The king is on h1; 22...f3 traps the bishop and gives Black a real material edge.> That's what i forgot and stopped calculating. The king was still on g1 in my head.> Here's a question to ponder: Supposing for a moment that the king really is on g1, and the bishop able to retreat to h1 ... what of it? Whether a buried bishop on h1 confronted by a protected pawn on f3 is better than a trapped and lost bishop is a nice question. In the former case, the bishop is still on the board, but its presence is more in the realm of potential than of actuality; unless Black releases it, the bishop remains imprisoned forever. |
|
| Oct-20-12 | | Abdel Irada: <James D Flynn: Chessgames, I don't speak Czech but I know enough Serbo-Croat to say that "i crni dobiva!" means "and Black is better"> Informative. The "i" is recognizable as "and" by analogy with the Spanish "y" and related forms. The "crni" is a bit more challenging until one recognizes its close kinship to the Russian "cherno." And that leaves "dobiva," whose etymology I don't know Slavic languages well enough to trace, but now by elimination I know it means "better." |

 | | Phony Benoni: <Abdel Irada> "Dobiva", or "better", derives from the name of former U.S. President George Dobiva Bush. (Unpaid non-political pun.) |

That's it. Off to the PUNitentiary with you. |

| Oct-20-12 | | ajax333221: Thanks, I learned a lot from this puzzle! I knew sooner or later I would find a life-changing masterpiece in this site. Also, 29...Rd1 looks like another puzzle.
:) |
|
| Oct-21-12 | | FlashinthePan: I saw 18...Qb3 with virtually the same continuation as in game, but thought I was missing something better as it was unclear to me that the ending game was won for Black. BTW, if White had played 24.Nc2, protecting the a1 square and clearing the way for his rook on the 1st rank instead of blocking his king with Rg1, I still don't see how the game is easily won for Black. |

| Oct-22-14 | | sls: <Abdel Irada: <James D Flynn: Chessgames, I don't speak Czech but I know enough Serbo-Croat to say that "i crni dobiva!" means "and Black is better">>
No, it means "and Black wins!". |
