| Jan-19-11 | | CHESSTTCAMPS: In this middlegame attacking posiiton, white has a centralized bishop for a passive knight, a marauding rook that controls black's 8th rank, and an advanced pawn chain that threatens the black king. However, the pinned bishop is lost (black threatens 43... Qxe5+), so White must finish now or lose. After the familiar tactic 43.Rxh8+ Kxh8 44.Qxh6+ Kg8, white has no continuation and can resign. Fortunately, white has another forcing line that does the trick: 43.Qxh6+! Kxh6 (gxh6 44.Rxh8#) 44.Rxh8+ Kg5 45.Rh5#
Easier than the average Wednesday, but an unusual finale worth sharing. |

| Jan-19-11 | | 1.e4effort: Gotta force something here, should it be the R or the Q? This is a game from 1904 - should be straightforward enough. I say sac the Q - 43. Qh6+. Black can reply by taking the Q with the K or the pawn at g7. Taking with the King puts him on the road to nowhere, as he has but 2 steps left to walk in this life:
43...Kxh6
44. Rxh8+...Kg5
45. Rh5#...1-0 |

| Jan-19-11 | | Patriot: <Once> Thanks again for your kind words. What you said is so true. If you do good things in chess (or life), good things will happen--magic will happen. I quickly went over the game and white did something that many players do not do--push their pawn majority. My instructor noticed this is a trend recently in my blitz games. He said "You must push your majority!" Especially if that is your only advantage you must do so or it's as if there is no advantage at all. This game is a good example of this. Last night during a tournament, my opponent blundered and I had an extra pawn. What did I do? I mobilized my pawn majority and it worked! It wasn't easy because we both had a rook, but it was a matter of using the advantage I had. IMO, everyone should at least quickly play through this game and see how white used his pawn majority. This principle is a good one to know! |

| Jan-19-11 | | CHESSTTCAMPS: <Ratt Boy: ><Amazing, how the mind works sometimes. A fresh look brings the answer! > This has happened to me a number of times when I've gotten stuck. To <Patriot>, another possible answer for slumps. <Ratt Boy> to <plateos>:
<What I do, is to click on the game link and immediately goto the bottom of the page to post.> Yes, many of the regular contributors follow this method (first entering solution into Notepad), a great way to practice deep visualization on the harder puzzles. |

| Jan-19-11 | | TheaN: A summarized version of Once's post would be like
<Once: (...)do the good stuff, have faith, and magic will happen.Usually.>
I chuckled at the last word; in fact is all what is chess about. Even super GMs go into lines they are not 100% sure about it will win or draw them the game. Good stuff again, as... usually. |

| Jan-19-11 | | Ghuzultyy: This one was easier than this week's Monday in my opinion. |
|
| Jan-19-11 | | zooter: Surely too easy for a Wednesday....
43.Rxh8+ Kxh8 44.Qxh6+ Kg8 45.Kxg7# -- no wait, 45...Rxg7 :( Good that I give my candidate moves a second glance. So lets change the order of moves and see if it's worth anything 43.Qxh6+ and now if
43...gxh6 44.Rh8# and
43...Kxh6 44.Rh8+ Kg5 45.Rh5#
Time to see if I missed anything |

| Jan-19-11 | | David2009: A Neumann vs Przepiorka, 1904 White 43? My first thought 43 Rxh8+ Kxh8 44 Qxh6+ (pattern recognition) loses, so does my next thought 43 Qxh6+ Kxh6 44 Rxh8+ Kg5 45 h4+?? 0-1, then I spot
the clincher 45 Rh5#. Check:

Good discsuuions from the regulars, with a perceptive insight Dec-21-10 from Phony Benoni: <This may be a case where a knowledge of mating patterns leads a player astray.
There's a standard shot in this kind of position: 1.Rxh8+ Kxh8 2.Qxh6+ Kg8 3.Qxg7#. Except, of course, that the Re7 covers the mate in this case. Przepiorka may have seen this, and never considered that White would be able to reverse the moves on him.> |
|
| Jan-19-11 | | cyclon: 43. Qxh6+ Kxh6 (-gxh6 44.Rxh8X) 44. Rxh8+ Kg5 45. Rh5X ( in other words, "cufflinks" ). |

| Jan-19-11 | | jaapvo: If you could win like this, only once in your life... |
|
| Jan-19-11 | | Killingsworth: This appears to be more of a Sunday/Monday puzzle. Two lines, forced moves. Mate in 2 or mate in 3. Many of the games from 100+ years previous appear to be compositions. |

 | | doubledrooks: With white's rook, bishop, and queen striking at black's kingside, a forcing combination could be available. And indeed it is: 43. Qxh6+ Kxh6 (...gxh6 44. Rxh8#) 44. Rxh8+ Kg5 45. Rh5# |
|
| Jan-19-11 | | Once: <patriot> Yup - pawn majorities are not well understood. We sometimes get too dazzled by tactics, or obsessed by openings, that we can overlook the really simple stuff. Another one is the concept of seizing space. If you haven't got any tactics to play, then it's often worth grabbing a little bit more of the board, a file, a diagonal, an outpost or just nudging a pawn or queen a little bit higher up the board. It took me a long while to get my head around that one. Good to hear that you are back to winning ways! |
|
| Jan-19-11 | | MiCrooks: Looked first at Rxh8+ Kxh8 Bxg7+ Kxg7 Qxe7+ but was unconvinced. White probably winning due to the advanced f pawn but queen endings are so tricky due to the perpetual threats. The two stars made me look for something clearer and then Qxh6+ jumped out. Nice cooperation between the Bishop and Rook in the final mating postion. |

| Jan-19-11 | | Bobby Fiske: It was the year of 1904. The 43 year long war had taken its heavy toll. Once a white and proud army was now decimated into a couple of pieces of artillery and a handful of soldiers. The dark forces was marching forward, threatening the fair-haired king who stood unguarded in the open battle field. From a distant hill she observed the combat. Her armor was poor but her bravery at war was legendary. They said she was gifted by Caissa at birth. She realized the battle could not be won by traditional means. Without hesitation she rode directly towards the castle of the dark lord. Fighting her way through enemy lines, she was dealt a deadly wound. But her sacrifice was rewarded. Paralyzed by the unexpected move, the enemy king had no escape route and he was killed in the crossfire. All of a sudden the white army had won the war. In the year 2011 the queen of this story was declared a martyr by the members of Chessgames. They named the brave heroine Saint Joan of Arc. |

| Jan-19-11 | | bachbeet: My problem with some of these, including this one, is that I am very reluctant to give up my queen. That's why I don't always see the solution unless a queen sac is really obvious. |
|
| Jan-19-11 | | James Bowman: Didn't see the final rook mate somehow, but the rest was fairly simple. I guess I need to look longer than a minute, patience patience. |

| Jan-19-11 | | WhiteRook48: I got it. Noticing that the g7-pawn is the only thing preventing 43 Rxh8# I decide to make sure the g-pawn is not there.
43 Qxh6+ Kxh6 (43...gxh6?? 44 Rxh8#)
44 Rxh8+
pretty obvious, the knight has no protection and the king only has one move
44...Kg5 45 Rh5#

 | | Phony Benoni: <Bobby Fiske> Wasn't Saint Joan of Arc the wife of Noah? Looks like my forecast was off, since many more solvers than I expected looked at the pattern with <30.Rh8+> first. It is a useful idea that has saved a couple of lost positions for me. 
click for larger viewA pawn down with a lousy position, the best I can really hope for is trading off heavy pieces and hoping to draw with the bishopps. But when Black played <29...h6>, I started thinking about setting up the pattern. After <30.Bd4 Qc7 31.Qe3 Ra2 32.Be5> Black made the error I was praying for with <32...Qa7?>. 
click for larger view32...Qc6, to interpose with ...Be8, is fine. But now you know what's coming! <33.Rb8+ Kh7 34.Rh8+! Kg6> (No choice, but the fun is just beginning.) <35.Qf4> (Planning 36.Rxh6+ gxh6 37.Qf6+, and mate follows.) <35...f6 36.Rxh6+! Kf7> 
click for larger viewNow, what I really, really, REALLY wanted to play was 37.Rxf6+ Kg8 38.Rf8+ Kh7 39.Rh8+ Kg6 40.Rh6+, and the rook must finally be taken. Unfortunately, Black would answer with 37.Rxf6+ gxf6 38.Qxf6+ Ke8, and White has no more than a draw. 37.Rh7 is probably best, but I settled for <37.Bxf6>. It's mate is the bishop is taken, while the queen falls if the rook is taken. Black chose <37...Kg8>, and resigned after <38.Rh8+> when we're back where we started and mate is unavoidable (38...Kf7 39.Bd4+ Kg6 40.Qg4+ Kf7 41.Qxg7#). |

| Jan-19-11 | | Brandon plays: Hmm, shouldn't this have been in the easy category. I don't know. Qxh6 just jumped out at me right away. |
|
| Jan-19-11 | | Patriot: <Phony Benoni> That looks like an interesting game. After black's mistake, you were relentless! Nice tactics there. I'm just glad I wasn't black. |

| Jan-19-11 | | Nullifidian: This one is even easier than Monday.
