 | | An Englishman: Good Evening: Beautiful combination! However, it works because White played 22.Qg1, and the Queen no longer defends f3. How does Black win after 22.Bg1,Bc6; 23.Nf3 (or Bf3)? |

 | | chessgames.com: <Kt going the wrong way> Our computers show both knight sacs as winning, with 20...Nfxd5 being slightly more accurate. |

| Jul-03-16 | | Sokrates: <Penguincw: Ugh, a Sunday puzzle. Couple things I notice about a Sunday puzzle. Firstly, (like today), there's hardly any comments (shouldn't come as a surprise). On Sundays, I've seen half an hour before the first comment....> Perhaps Sunday doesn't arrive at the same hour for all participants of this site? Just a thought sent from Copenhagen. |

 | | scormus: instructive puzzle. The instinct is to take the g-pawn but I found that leads nowhere, neither with N nor h-pawn. W's weakness lies in the diagonals and the f-file, anf the K wont be able to hide when they are open. 20 ... Nxd5 is logical though I confess I was too fixated about taking the g-pawn to see it. |
|
| Jul-03-16 | | thegoodanarchist: Now THAT was a nice little combination by Black from move 20. |
|
| Jul-03-16 | | diagonalley: join others in admiration of this beautiful combination and finish ... not perhaps "insane" although definitely extremely hard to visualise and calculate |
|
| Jul-03-16 | | morfishine: <al wazir: This game is labeled a Nimzowitsch Defense, but it isn't. It's a Pirc/Robatsch/Modern opening that transposes into a KID. That's the only thing I got right, but I want full credit anyway for pointing that out.> I don't think anybody really cares |
|
| Jul-03-16 | | john barleycorn: nice game. the combination brought back some memories to this one Letelier vs Fischer, 1960 |
|
| Jul-03-16 | | Hans Kastorp: With a queen and a rock down the black finally had a sweet choice between Nf4# and Nc3#. Awesome! |
|
| Jul-03-16 | | mel gibson: This was super hard & an excellent game by black.
DR4 64 bit agrees with the text move but white fights a little
better - yet still loses badly. |
|
| Jul-03-16 | | AlicesKnight: <john barleycorn> Excellent example. Also perhaps Baratz vs Menchik, 1928 |

 | | Sally Simpson: Too much like hard work for a Sunday Morning. Rarely try a Saturday/Sunday puzzle. Far to lazy. Slowly clicked through it nodding in agreement with every move like a typical C.G. Kibitzer marking a school report. I was looking for the Monday puzzle.
Ahha! Black to play.

Not going to miss that one. A few days ago in 3 minute blitz on Gameknot I had a spiritual experience that featured a Queen sac and mate with a Knight and two Bishops. Here White to play:

But the ghost of Marshall moved the Queen to d6 (OK it was a mouse slip.) 19.Qd6 Kg7

|
| Jul-03-16 | | YouRang: Now that was an impressive mate!
I didn't get it, although I did at one point think that ...Nfxd5 was a likely opening move because it opens the Q+R battery on the f-file, and (after exd5 ...Nxd5) plants a strong N on d5. But the fog was too thick to see how to proceed from there. |
|
| Jul-03-16 | | YouRang: One key point I overlooked was that removing Pd5 also opened c6 as a wonderful attacking square for the LSB. With this, black's bishops really ruled the board, as the final position attests. |
|
| Jul-03-16 | | agb2002: The material is identical.
White has the positional threat h-pawn 21.cxd6 cxd6 22.Nb6 Rd8 23.Nxd7 and the h-pawn is under attack. The white king doesn't look very safe. This suggests 20... Nfxd5, to open the f-file and the a8-h1 diagonal and creating several threats (Nxe3+, Rf2+, Bxa4-Nc3, etc.): A) 21.Bg1 Rf2+ 22.Bxf2 Qxf2#.
B) 21.Nf1 Nxe3+ 22.Nxe3 Rf2+ 23.Kg1 (23.Bxf2 Qxf2#) 23... Rg2+ 24.Nxg2 (24.Kxg2 Qf2#) 24... Qf2+ 25.Kh2 Bg3#. C) 21.Nc4 Nxe3+ as in B.
D) 21.Qb3 Rf2+ 22.Kg1 Rxe2 23.Qxd5+ Kh8
D.1) 24.Qd3 Bb5
D.1.a) 25.Qc3 Bf2+ wins (26.Bxf2 Qxf2#; 26.Kg(h)2 Bxe3+ 27.Kg3 Qf2#). D.1.b) 25.Nc4 Bxc4 26.Qxc4 Rxe3, with two extra pawns and the threats Qf2# and Rg3+, looks winning. D.2) 24.Nc4 Rxe3 25.Nxe3 Qf2#.
D.3) 24.Qe4 Bf2+ wins decisive material.
D.4) 24.Qf3 Bc6 25.Qxf8+ Rxf8
D.4.a) 26.Nf1 Rg2#.
D.4.b) 26.Rh2 Rxe3 - + [2B+2P vs 2N]. |

 | | Jimfromprovidence: Wish I had seen that after 20...Nfxd5, below, black has a forced mate in 4 threat beginning with 21...Rf2+.

| Jul-03-16 | | poachedeggs: Got the initial idea of activity the black pieces by exchanging knight for pawn. But getting the bishop to C6 for the later discovered check got me. |
|
| Jul-03-16 | | Virgil A: Amazing! |
|
| Jul-03-16 | | Patriot: <agb2002> In your line D) after 23.Qxd5+, why not 23...Nxd5? |
|
| Jul-03-16 | | BOSTER: Strategic important point like pawn d5 should be oberprotected.
So, 19.c5 was simple blunder. |
|
| Jul-04-16 | | agb2002: <Patriot: <agb2002> In your line D) after 23.Qxd5+, why not 23...Nxd5?> I forgot to include 21.exd5 Nxd5, sorry.
I had a look at the puzzle early in the morning in Segovia (https://en.m.wikipedia.org/wiki/Seg...) and posted my solution in Murcia (https://en.m.wikipedia.org/wiki/Mur...) after driving five hours. By the way, Isabel I, the queen who presumably inspired the current powerful piece of chess, was crowned in Segovia on Dec 13, 1474. |
|
| Jul-04-16 | | Patriot: <agb2002> Ah ok! Yeah I also wondered why you didn't include such a critical move as 21.exd5. That's cool about Segovia.
Have a safe trip. |
