| Sep-17-14 | | stacase: Black's Queen Rook and e5 Pawn are all placed just right for White's Queen to say mate in the middle of the board. 25 Rg7 paves the way. |
|
| Sep-17-14 | | patzer2: Earlier 20. h4!  was a nice shot. After 20...Bxh4 21. Bxh6! is decisive.If 21...gxh6, then simply 22. Qxhg6 . |
|
| Sep-17-14 | | agb2002: White has two pawns for a bishop.
The first idea that comes to mind is to expose further the black king with the moves Rxg7, Rg1, Qg2 and f6, in the appropriate order. The simplest winning maneuver seems to be 25.Rxg7+ Kxg7 26.Qg2+: A) 26... Kf6(7) 27.Qg6#.
B) 26... Kh6 27.Qg6#.
C) 26... Kh7 27.Rh1+ Qh4 28.Rxh4#.
D) 26... Kh8 27.Rh1+ Qh7 28.Rxh7+ Kxh7 29.f6+ and mate next. E) 26... Qg5 27.Qxg5+ + - [Q+2P vs R]. |
|
| Sep-17-14 | | morfishine: <25.Rxg7+> and White wins <25...Kxg7> forced
<26.Qg2+> and Black has no good move (1) 26...Kf7 27.Qg6#
(2) 26...Kf6 27.Qg6#
(3) 26...Kh6/h7/h8 27.Rh1+

| Sep-17-14 | | gofer: Well move 1 is obvious, black's reply too. But what next; f6+? Rg1+? Qg2+? <25 Rxg7+ Kxg7>
<26 Qg2+! ...>
Ouch! All king moves lead to disaster and the only queen move leads to
a loss...
26 ... Kf7/Kf6/Kh6 27 Qg6#
26 ... Kh7 27 Rh1+ Qh4 28 Rxh4#
26 ... Kh8 27 Rh1+ Qh7 28 Rxh7+ Kxh7 29 f6+ Kh6 (Kh8/Bf5 Qg7#) 30 Qg6# <26 ... Qg5>
<27 Qxg5+ Kf7>
<28 Rh1 ...>

| Sep-17-14 | | Olsonist: Mondayish. Even I got it. It had to start with Rg7. |

| Sep-17-14 | | Nick46: <plumbst> Nicely explained. Very helpful even after I had hit on the solution "intuitively". |

| Sep-17-14 | | Once: After too many years watching horror films, I've come to a startling conclusion: <It's all about the fog.> The people who make horror films or books are contractually obliged to include at least one scene where our hero walks towards danger. The creepy locked door at the top of the deserted house ... The scrabbling noise from the cellar ...
The bank of fog rolling in from the graveyard at midnight ... And that's when we want to shout at the screen, the kindle or the book - "Go in the opposite direction, you fool!" But they never listen. For some inexplicable reason, our hero or heroine has to go towards the quite obviously scary thing. If they are the main character, that might not be a problem. But you know it's not going to end well if they are one of the "also starring" cast. It's the same with chess puzzles. Today we have to find an easy first move and a foggy second move. From the starting position, we simply have to play 25. Rxg7+ Kxg7. The rook sac drags the undead black king out into the sunlight where we can stab him through the heart. His reply is forced if he doesn't want to lose his queen. And that leads us to here:
click for larger viewNow we have three tempting possibilities. We could eviscerate him with a wooden stake in the cloisters (nasty!) with 26. Qg2+ We could shoot him with silver bullets with 26. Rg1+. Or we could force-feed him a tasty spaghetti dish laced with holy water and unholy garlic with 26. f6+ Which to choose? Here we should use the Once guide to surviving horror movies. Stay out of the fog! 26. f6+ is tempting because it forks queen and king, but either 26...Qxf6 or 26...Rxf6 leaves us wondering where are counterplay is coming from. The lines get as murky as a Trannsylvanian mountain side on a moonless night. Similarly, 26. Rg1+. Then the black king runs back to his crypt with Kf7 and Ke8. The lines get foggy. Hard to see what it going on. So to 26. Qg2+
click for larger viewIf the black king turns into a bat and flies to the f file, we swat him down with Qg6#. If he runs to the h file, we load up with silver bullets with Rh1+. All he has left is to sacrifice his queen to delay the inevitable. 26. Qg2+ is the least foggy of all the options, and it turns out the only one to win. At the risk of a shameless plug, here's a shameless plug. There's news of a free book on my profile page. Just click on the blue... |

 | | Penguincw: Normally I don't get Wednesday puzzles, but I got this one, so maybe it's a wee too easy. |
|
| Sep-17-14 | | paavoh: This should've been a Tuesday?! Rxg7 followed by Qg2 and Qg6/Rh1. |
|
| Sep-17-14 | | patzer2: Thought Black might have survived the complications leading to our Wednesday puzzle position with 23...Rf7. However, Fritz indicates Black succumbs to White's slow but steady build-up of threats after 23...Rf7 24. Rg6! (diagram below).
click for larger viewFrom here it's slow torture for Black as White piles on the pressure until the indefensible position finally cracks. Fritz, for example, indicates play from the diagram above (i.e. after 23... Rf7 24. Rg6!) might continue 24...Kf8 25. Be3 Qd7 26. Rh1 Ke7 27. c4 Rdf8 28. c5 Ke8 29. Rc1 Qd8 30. cxd6 Rd7 31. Qh2 a5 32. Bg5 b5 33. Bxf6 gxf6 34. f4 Ba6 35. fxe5 b4 36. exf6 Rxd6 37. Qe5+ Kd7 38. Rg7+ Rf7 39. Rxf7+ Qe7 40. Qxe7#. |
|
| Sep-17-14 | | Lighthorse: Yeah, this looked to me more like a Monday puzzle. Much too easy. After Rxg7+ it was obvious to me the next move was Qg2+. |
|
| Sep-17-14 | | patzer2: <Once> Neat story lesson today on avoiding the fog! A Chess Master friend once told me "If you can't see it (i.e. a combination) through (i.e. to a clear advantage), don't play it!" |
|
| Sep-17-14 | | kevin86: White forces mate or wins the queen.
THE EPAULETTE: 26...♔f6 or ♔f7 27 ♕g6#
THE S♕UEEZE: 26...♔h6,7,or8 27 ♖h1+ and mate next.
THE QUEEN: 26...♕g5 27 ♕xg5+
the end... |
|
| Sep-17-14 | | AvidChessMan: The key was opening up the g and h files and it started with the h pawn sacrafice at move 20. Castling queenside enabled white to win with this stratagy. It lead to a lot more attack options for white than black. |
|
Sep-17-14
 | | Bubo bubo: 25.Rxg7+! Kxg7 (otherwise Black loses his queen for a rook, with White's attack still running)
26.Qg2+! and now either 26...Kf~ 27.Qg6# or 26.Kh~ 27.Rh1+ and mate next move. Although the second move should be obvious, I wasted several minutes calculating the more natural-looking 26.Rg1+ and even questioned my first move until I finally realised that the queen does it better on the g-file :-( |
|
| Sep-17-14 | | WJW147: Rook takes Bishop at g7 puts Black to the sword. The game for Black is lost after that. |
|
| Sep-17-14 | | StevieB: That was too easy for a Wednesday. |
|
| Sep-17-14 | | beenthere240: I wonder what 23. Be4 was all about -- waiting to see if black would cut off his queen from the g7 square??? |
|
| Sep-17-14 | | Lambda: I think you need to see what happens after Rxh7+ Kxh7 to call it a full solution. Queen and two pawns against two rooks isn't an obviously decisive material advantage, and if the attack was fizzling out at that point, you'd want to check if there was something better. |
|
| Sep-17-14 | | TheBish: T Heinemann vs G Meins, 2004 White to play (25.?) "Medium/Easy"
White is down a piece for two pawns, but one of those pawns, on f5, plays a key role in the attack. 25. ♖xg7+! ♔xg7 26. ♕g2+!
This is key; I spent some time looking at the weaker 26. Rg1+, after which it looks like Black defends by 26...Kf7 (but not 26...Kf6?? 27. Qg5+ Kf7 28. Qg6# or 26...Kh8?? 27. f6! followed by 28. Qh2+ and mate. 26...♔h8
If the king goes to f6 or f7, the answer is 27. Qg6#; anywhere else on the h-file, 27. Rh1+ is the knockout punch. 27. ♖h1+ ♕h7 28. ♖xh7+ ♔xh7 29. f6+ and mate is very near (29...♗f5 30. ♗xf5+ ♔h8 31. ♕g7#). |
|
| May-04-21 | | Messiah: Terrible! |
|
| May-04-21 | | Brenin: <beenthere240>: I also wondered about 23 Be4: the Ps on f3 and d5 aren't in any danger, so they don't need extra protection. Perhaps White wanted to prevent any attempt at counterplay with the P-sac 23 ... e4 24 fxe4 Qe5, threatening mate on b2, but 25 c3 deals with that. In its favour, this loss of an attacking tempo had the effect of encouraging Black to run into a trap with 23 ... Kf7 when he didn't have a safe escape route to e8. |
|
| May-04-21 | | Cheapo by the Dozen: If Heinemann won the tournament, or secured a placement with this particular game, it's a great pun. Otherwise ... well, since it's a game to be proud of, the pun isn't horrid even then. |
|
| May-04-21 | | goodevans: <Brenin>, <beenthere240>, It occurred to me that White might have had in mind to double his Rs on the g-file and saw that <23.Rg3?> would lose to <23...e4>. But instead of blocking the e-pawn he could instead just have played <23.Rg4> so I guess that blows that theory. |
