| Dec-08-17 | | BOSTER: <C by the D>:<29 Bc2 Nef5 30.Bxe4>. 30.Qxh7#. |
|
| Dec-08-17 | | kevin86: White lures the queen away from h7, then locks her out and goes after the pawn...soon winning said queen. |
|
| Dec-08-17 | | awfulhangover: Yes! Found the Bc2-Nd3 idea! Good enough for me ... |
|
| Dec-08-17 | | Patriot: I found the game moves thru 34...Qxc2 which surprised me since strong regulars didn't. But that wasn't easy. |
|
| Dec-08-17 | | Patriot: Sorry I meant 34.Qxc2. |
|
| Dec-08-17 | | unferth: is there bad blood between these guys? trying to understand why this game doesn't end at move 33... |
|
| Dec-08-17 | | QueenMe: Got this immediately; all the way through capture of the queen. Now I need to get Photoshop to put a halo around my avatar. |
|
| Dec-08-17 | | njchess: It took me a looong time to find the game line. I found Bc2 easily enough, but until I followed it with Nd3!, it didn't make much sense. And even then, it took me a moment to realize that Black's queen couldn't just take the knight. Then, it all fell into place, including the nifty Ne5+. So smooth. |
|
| Dec-08-17 | | agb2002: White has a bishop for a knight and a pawn.
Black threatens gxf4, Qxd4+, Rxd4.
The attempt of obstruction 30.Ng6+ is met with 30... Qxg6 but this suggests the maneuver Be6-f5 starting with 30.Ne6. However, after 30... Nxe6 31.Bxe6 Ng8 (31... Qxe6 32.Qxh7#; 31... Qxd4+ 32.Kh1 Qe4 33.Bf5 wins decisive material) 32.Qh5 h6 33.Bxg8 (33.Bf5 Qxd4+ 34.Kh1 Qd6 35.Qg6 Qe7 and the attack seems to vanish) 33... Kxg8 34.Qxh6 Qxd4+ 35.Kh1 Rd7 seems to hold. If blocking on f5 does not work perhaps it would work on d3, so 30.Bc2: A) 30... Qxc2 31.Nd3 Kg8 32.Qxh7+ Kf7 33.Ne5+ and 34.Qxc2 wins decisive material. B) 30... Qxd4+ 31.Kh1 Kg8 32.Ne6 and the double threat Qxg7# and Nxd4 wins (32... Nxe6 33.Qxh7#). |

| Dec-08-17 | | thegoodanarchist: I didn't get close to solving this one. |
|
| Jan-03-25 | | Mayankk: I thought the answer was the cute little 30 Ba2, threatening 31 Bb1 and mate at the h7 square. I did look at the possibility of an immediate 30 Bc2 but thought it is inferior to 30 Ba2. I missed the fact that Black Queen can move away with a tempo, via Qxd4+, anytime it wanted. And Kg8 is available once the White Bishop vacates that killer diagonal. Should have looked harder. 30 Bc2 Qxc2 31 Nd3 is a pretty line. |
|
| Jan-03-25 | | EasilyConfused: @Mayank, I think ba2 is a great move. After the spite check, the black Queen must return to protect the pawn and prevent mate. Then bb1 wins the Queen. |
|
| Jan-03-25 | | mel gibson: I saw the first ply then rejected it because I didn't see the Knight could block the Black Queen. Stockfish 17 says:
30. Bc2
(30. Bc2 (1.Bc2 Qxc2 2.Nd3 Qxd3 3.Rxd3 Ngf5 4.Qh5 Ng7 5.Qh3 Nd5 6.Qh6 Rf7 7.h4 gxh4 8.Qxh4 Ne6 9.Qg4
Nf8 10.Rf5 Rg7 11.Qh3 Rf7 12.Rdf3 Rdd7 13.Rg3 Ne7 14.Rf4 f5 ) +2.81/45 284) score for White +2.81 depth 45. |
|
| Jan-03-25 | | King.Arthur.Brazil: There's no much moves, although the king lose some time to find the best option: 30. Bc2 Qxc2 (30...Ng8 31. Qxh7+ Qxh7 32. Ng6#) 31. Nd3 Kg8 32. Qxh7+ Kf7 33. Ne5+ Ke8 34. Qxc2l... |

 | | Teyss: Simple once you see it... which I didn't. Three ideas to combine: deflection sac (Bishop), interposition (Knight), check (Knight) with long-range discovered attack (Queen). Yup, seems simple. Hi Mayankk,
After 30.Ba2 I would first play ...gxf4 (could never resist taking a piece and it prevents 31.Ng6+) and SF agrees (-1.8 at 22 ply).
(a) Now if 31.Bb1, as you say 31...Qxd4+ followed by 32...Kg8 and White has lost the edge (-3.5 at 33 ply).
(b) If 31.Rxf4 to protect the d4 Pawn, ...Qg6 and the attack is gone. 30.Bc2 prevents the two defences ...gxf4 and ...Qg6. Black can still try the spite check 30...Qxd4+ but is lost afterwards: 31.Kh1 and if now ...Kg8, 32.Ne6! wins.

(a) 32...Nxe6 33.Qxh7#
(b) 32...Q~ 33.Qxg7#
(c) 32...Other 33.Nxd4 |

 | | steinitzfan: A very gratifying combination. I've seen interposition before and I've seen deflection but I can't say as I've seen them tied together that way. I'm sure there are other examples but I can't recall any. |
|
| Jan-03-25 | | vajeer: It took me a bit longer and once I found it I thought it's not even Friday level. Going through the kibitzing I see many missed it and once they saw the solution thought that they should have found it. What in this puzzle makes it tricky I wonder. |
|

| | Open Defence: <vajeer> it's just our visualization block, the idea is no doubt simple, it's just that sometimes something is right under our noses and we don't see it .... though we should |
|
| Jan-03-25 | | alshatranji: Same as Mayankk. Beautiful game, and finally a proper puzzle. |

 | | scormus: I feel embarrassed to admit that this was another one that got away.
I'll console myself with being in good company.
And excuse myself by claiming that 31 Nd3! was hiding in plain sight. |
