38 Rd8+ was a fun one |
|
| Feb-25-16 | | agb2002: The material is identical.
Black threatens 33... Rxe6.
The pawn on h6 suggests 33.Qxg6+ hxg6 (else mate next) 34.h7 Rxe6 (else 35.h8=Q#) 35.h8=Q+ Kf7 36.Qh7+ (36.Rd8 Re1#) 36... Kf8 (36... Ke8 37.Qg8#) 37.Rd8+ Qxd8 38.Qh8+ Kf7 39.Qxd8 + - [Q vs R+P]. However, White would need to create a second weakness on the king side to win the game by invading Black's fortress with the king. For example, 39... Rd6 40.Qh8 g5 (or 40... f5 and the white king would march to g5, h6, etc.) 41.Qh7+ Ke8 42.Qf5 followed by Kh2-g3-g4-h5-g6-g7 and the attack to e7 and b6. |

 | | perfidious: <stacase: 38 Rd8+ was a fun one> Unless, of course, one were Black. |
|
| Feb-25-16 | | The Kings Domain: Nice one. One of those single moves that ends it all. |
|
| Feb-25-16 | | morfishine: I zeroed in on <33.Qxg6> fairly quickly because there's really not much else; Of course, I didn't rattle off all the moves through 46 |
|
| Feb-25-16 | | whiteshark: The 'usual' Thursday failure:
I had all motifs, however I didn't manage to combine them sensibly. Then a dystopian vision of ...Re1# soared, and that's it. :(( |
|
| Feb-25-16 | | Cheapo by the Dozen: As in many puzzles, it was easy to see a few moves in this one, that led you to at least an improved position with an attack, and with any luck a big win. I generally stop solving when I reach that point. :) |
|
| Feb-25-16 | | gofer: This one is quite simple for a Thursday...
33 Qxg6+ hxg6 (forced)
34 h7 Rxe6 (forced)
35 h8=Q+ Kf7 (forced)
36 Qh7+ Kf8 (forced)
37 Rd8+ Qxd8 (forced)
38 Qh8+ Kf7 (forced)
39 Qxd8

Yep, but it seems white didn't quite see it so clearly and black didn't realise that he had
been let off the hook by <36 Rd1?!?!> |
|
| Feb-25-16 | | cocker: Very strange blunder by White (36 Rd1) then one by Black (37 ... Kf8 after preparing f6). |
|
| Feb-25-16 | | WorstPlayerEver: Nice. Makes me think of John Lennon.
Remove pawn e7 from play and put the BK there. Instead of White's Qg6 now Black threats to take pawn e6 at White's 33th move.. Imagine there are no engines
And you would beat everyone at chess |

 | | Bubo bubo: White wins the queen for a rook with
33.Qxg6+ hxg6 (or Kd8 34.Qg8#; 33...Kf8 34.Qg7+ Ke8 35.Qg8#) 34.h7 Rxe6 (otherwise 35.h8Q#) 35.h8Q+ Kf7 36.Qh7+ Kf8 (or Ke8 37.Qg8#) 37.Rd8+ Qxd8 38.Qh8+ Kf7 39.Qxd8. Nice, but not very difficult for Thursday! |
|
| Feb-25-16 | | patzer2: In attempting to solve today's Thursday puzzle, I got as far as 33. Qxg6+ hxg6 34. h7 Rxe6 35. h8(Q)+ Kf7. Then, like White in this game, I gave away the win on the next move. White's mistake was 36. Rd1? = when the computers indicate it's a draw after 36...f5 37. Qh7+ Kf6 = (not 37...Kf8? as played in the game). My mistake was 36. Kf1?, which allows 36...Rd6 = (0.00 @ 21 depth, Deep Fritz 15). Before this, Black's 32...Rd6 allowed the winning combination 33. Qxg6+ (+3.94 @ 29 depth, Deep Fritz 15). Black could have tried to put up more resistance with 32...Rxd5, but White still wins after 33. Qxd5 Qd6 (33... Qa7 34. f4! Qb8 35. Qd7+ Kf8 36. Kh1 Qa8 37. Qc7 Qe8 38. Qxb6 ) 34. Qa8+ Qd8 35. Qc6+ Kf8 36. g3 Qb8 (36... Kg8 37. Qd7 Qf8 38. Qc7 f5 39. Qxb6) 37. Qd7 Qa8 38. Qc7 Ke8 39. Qxb6 (+7.27 @ 22 depth, Deep Fritz 15). Prior to all this, Black's decisive mistake was 30...Kf8? which allows 31. Rxd8+ Qxd8 32. g3! or 31. Rd5 as in the game. Instead, the simple 30...Kxh6 = holds the position level as play might continue 30... Kxh6 31. Qh3+ Kg7 32. Rd7 Rxd7 33. exd7 f5! = (0.00 @ 25 depth, Deep Fritz 15). |

|
| Feb-25-16 | | saturn2: It is a full point for me today but not an easy one. At the first I thought it is a monday but then i got desperate because the new queen can only give eternal check on h7 Nd h8 and also black has the matethreat Re1. However then I saw 37 Rd8! |
|
| Feb-25-16 | | YetAnotherAmateur: Definitely saw the easy part:
33. Qxg6+ hxg6 (refusing the sac with a king move is no good due to Qg8# or Qf7#)
34. h7 Rxe6 (anything else, and h8=R#)
35. h8=Q+ Kf7
Now at this point, the critical point is that white must stop the threat of Re1#. There are 3 possible ways of doing that: 1. Keep black in check with Qh7+. The comment explains how this wins. 2. g3, giving the king 2 escape squares. However, this also opens up possible attacks along the long diagonal, so this is probably less than ideal. 3. Rd1. This wins too, as shown in the game line. |
|
| Feb-25-16 | | Longview: <Patzer2> you answered the only question I had on this game....why not 30....Kxh6. leaving the pawn gave away a valuable square on g7 and set it up for a great sac promotion sequence (which I am proud to say I saw as my solution for the puzzle). I did not see a downside to Kxh6. I believe the pattern of advanced pawn and vulnerable opposing pawns is worth remembering. |
|
| Feb-25-16 | | kevin86: The black king is so wedged in that the sac of white's queen will lead to mate or the win of the adverse queen. |
|
| Feb-25-16 | | BOSTER: < patzer2: 30...Kxh6 holds the pos level. Fritz15 >.
What if 31.Rxd8 Qxd8 32.Qd5
Is this a draw, or not. |

 | | gawain: Well, it has to be 33 Qxg6+ leading to the queening of the h pawn. But I did not see clearly enough how to turn this into a win. The key (eventually) is the surprising move Rd8+. Part score. |
|
| Feb-25-16 | | Tiggler: Pretty odd that Zelcic played 33.Qxg7 without having seen the correct finish of the combination. Perhaps he was just looking for a quick way to draw, and only later found that he could win. |
|
| Feb-25-16 | | ndg2: Deflection and decoy themes in one combination. The queen sac deflects the black h-pawn from h7, so its white counterpart can march through to the eights rank. The rook sac is a decoy so the black queen can be x-rayed later on by white's queen check on h8. |
|
| Feb-25-16 | | Tuzmor: Qxg6 is not a real sacrifice, because not taking the Queen leads to a mate in one. Also, taking the Rook is forced.
Sacrifice is not the theme here, deflection is. |
|
| Feb-25-16 | | morfishine: I wouldn't be to hard on Zelcic for playing 36.Rd1
After all, he did find the Rd8+ theme |
|
| Feb-25-16 | | King.Arthur.Brazil: Directly:33... Qxg6 34.h7xg6 h7 and mate following. |
|
| Feb-29-16 | | Tiggler: <morfishine: I wouldn't be to hard on Zelcic for playing 36.Rd1 After all, he did find the Rd8+ theme>
Would not have helped him if Jovanic had found 37... Kf6 (draw). |
