| Dec-26-04 | | patzer2: One of the more interesting stories from the site I referenced above is the heart wrenching tale at http://www.christmas.com/pe/1097, which tells of an African celebration of Christmas joy in the midst of war, genocide and starvation. |

 | | Penguincw: Looked like a pretty straight forward puzzle, even though I didn't get it. I did get the obvious 25.Bxg6 hxg6 26.Qxg6+, and perhaps could've gotten the rest if I had seen 26...Kf8 27.Ne5. |
|
| Jun-10-16 | | agb2002: White has a bishop, a knight and a pawn for the bishop pair. The weakened castle and the possibility of creating a double threat with a knight on e5 leads to consider 25.Bxg6 hxg6 (else lose another pawn at least) 26.Qxg6+: A) 26... Kf8 27.Nce5
A.1) 27... fxe5 28.Nxe5 Qe8 29.Qh7 wins decisive material. For example, 29... Rxb2 30.Ng6+ Qxg6 31.Qxg6 Rb6 32.e4 Nf6 33.f3 with the queen and three pawns for three pieces and attack with ideas like d5 exd5 e5 and e6, Ra5 and Rg5, etc. A.2) 27... Qe8 28.Qh7 fxe5 29.Nxe5 transposes to A.1. B) 28... Kh8 27.Nce5 fxe5 28.Nxe5 Qe8 29.Nf7+ Qxf7 30.Qxf7 is similar to A. |

| Jun-10-16 | | gofer: Black has no attack whatsoever, but all his pieces on the queen side are reasonably well coordinated at defending each other. But the kingside is a different story... <25 Bxg6 hxg6>
<26 Qxg6+ ...>
The black king only has two choices and both lose the queen, which implies that the sacrifice is a simple win; Q+3P for 2N+B. 26 ... Kh8
27 Nce5 fxe5
28 Ne5 Qe8
29 Nf7+

<27 Nce5 fxe5>

<29 Qh7! ...>

Rather simple for a Friday, but the coordination of knight and queen is beautiful! ~~~
Yep! |

| Jun-10-16 | | agb2002: Worst coffe on Earth: I saw 30.Qh8# but forgot it when I started typing my post... |
|
| Jun-10-16 | | AlicesKnight: Actually saw the main elements this time! |
|
| Jun-10-16 | | Once: This one is a game of three halves. (?!)
First we need to see the bishop sac on g6. Then the knight reloader starting with 28. N(any)e5. Finally, the devastating net-closing with 29. Qh7, which has been a bit of theme this week. Good Friday puzzle, and a fitting tribute. |
|
| Jun-10-16 | | Razgriz: The bishop sacrifice was straightforward, but the knight sacrifice to cement the black king properly did not come as easy. |
|
| Jun-10-16 | | WorstPlayerEver: This was not very hard lol |
|
| Jun-10-16 | | patzer2: Black's decisive mistake appears to be 23...Qd7? which is oblivious to threat of 24. Bxg6 or 24. Nc4 followed by 25. Bxg6 . Necessary instead was 23...Qe8 24. Nxb7  continuing to fight for the draw a pawn down. Early in the opening, I prefer 3...Nf6 = or 4...dxc4 = to  . |
|
| Jun-10-16 | | diagonalley: agree with several other posters... not unduly difficult, but a fine example of sacrificial play (nice one, viktor!) |
|
| Jun-10-16 | | Kasparov Fan: If one looks on this position long enough it will seem as if white doesn't have any useful move until the sac on g6 is seen. |
|
| Jun-10-16 | | Carlos0012358: Seems like after 25.Bxg6, 25....hxg6 weakens Black's King position and fails to engage the Black Queen. I thought 25....Bd8 would accomplish both, cause either the white Bishop to retreat or perhaps force a Queen exchange. |
|
| Jun-10-16 | | Rama: Why do I have trouble with Victor? I haven't gotten any since Tuesday. |
|
| Jun-10-16 | | kevin86: White sacrifices two pieces and ends with a surprise mate. |
|
| Jun-10-16 | | ajile: What's not to like about White's opening? The dark squared bishop is outside the pawn chain on a great diagonal. And White has play on the half open c file against Black's c pawn. White has all the positional benefits with no apparent weaknesses. One point is White might want to secure the DSB at some point with h3 so that ..Nh5 doesn't force a trade of knight for bishop. 13.a4 ended up working for White since Black got absolutely nothing for his pawn sac. So is winning a pawn worth the loss of the DSB and slight weakening of k-side pawns. Answer is probably yes. Suggestions for Black? First I never really liked the cutesy ..Qa5 check since what is the beneficial followup? Instead take down the DSB ASAP with ..Nh5 when it's safe to do so. In recent months since Kamsky has adopted these Bf4 systems Black has found ways to combat this opening. Granted playing Bf4 with pawns at c3-d4-e3 (London System) is different than pawns at c4-d4-e3 with the obvious difference that White controls when the c file opens in QGD variations. In London Systems with c3 Black usually plays c5-d5 and this counterplay offsets White's other advantages. If White can get away with a full QGD c4-d4 WITH Bf4 he is doing fantastic. |

| Jun-10-16 | | YouRang: This one wasn't too hard.
When a POTD presents a piece sac that puts your Q face-to-face with the opposing and poorly defended K, that's probably where its heading. So, <25.Bxg6! hxg6> the B sac <26.Qxg6+ Kf8> and black has to give up Q to stop mate: 
click for larger view ~~~~
IF <26...Kh8> then <27.Ng5> 2 mate threats <fxg5 28.Ne5> threaten Q and mate <Qe8 29.Ne7+>
click for larger view
Black must give up Q for N
~~~~
IF <26...Kf8> then <27.Nfe5> threaten Q & 2 mates <27...fxe5 28.Nxe5> renew same threats <28...Qe8 29.Qh7!> (threaten Qh8# and Ng6+)
click for larger view
Black must avoid Qh8#, but then can't stop both Ng6+, which again requires black to give up Q for N . So, white ends up sacrificing a B and N for Q plus 3 pawns, and still retains the initiative because the rooks and a kingside pawnstorm will be coming shortly. |
|
| Jun-10-16 | | YouRang: It's worth noting that after <25.Bxg6!>, the obvious 26...hxg6 is not blacks' best move. Perhaps better is <26...Bf8>
click for larger view
This opens the 7th rank for the Q to defend, and the Bf8 can block checks on the g-file. Still, white can just retract the B with <27.Bd3>, and black is badly wounded. I would expect white to start transferring force kingside, perhaps with a Kh2/Rh1/Kg1 manuever soon. |

| Jun-10-16 | | MorphinTime: It is time |
|
| Jun-10-16 | | stst: Quite many lines, one possibility:
25.Bxg6 hxg6
26.Qxg6+ Kf8
27.e4 (to dispel the N from rescue) Nb6/c7
28.Ne3 (revert to the K-side to add the force) f5
(to free the B@e7 to defend)
29.exf5 exf5
30.Nf5 Ne6 to guard g7
31.Nh6 Qe8
32.Qg8#
could go other ways of course.... |
|
| Jun-10-16 | | stst: Two points:
1. After Bxg6, hxg6 is not Black's best defense, true, for it invites the Q to the door.
2. 29.......Bf6 will put up some last effort to defend Qh8+, or Qh6+, instead of Rxb2 which does not help at all, is not delivering mate next, ...., it's quite meaningless move to stop the White Q. |
|
| Jun-10-16 | | mel gibson: Not hard to see this one -
sacrifice a bishop & get 2 pawns plus a close check on the King from the Queen &
as a bonus 2 knights that can move in to assist. |
|
| Jun-11-16 | | drollere: the sacrifice of B for 2 pawns and fishing checks works just as well without 23. Rc1, while 23. ... Qb8 seems a better retreat for the Q and prepares 24. ... Bd6. so i think 23. ... Qd7 was the blunder that makes e5 immediately a target for the N sacrifice and makes 24. Nc4 attacking the rook with tempo the first move of the combination. |
