| Sep-27-12 | | gofer: Monday "Difficult", Tuesday & Wednesday "Medium", Thursday "Very Easy"! ???
<39 ... Qxh3+>
<40 Kxh3 hxg3+>
<41 Kg2 gxf2+ >
41 Kf3 f1=Q+ 
41 Kf1 Rh1+ 42 Kxf2 Rh2+ as below
<41 Kxf2 Rh2+>
<42 Kf3 Rxd2>
<43 Bxd2 ...>
Black is an exchange and a pawn up, but now has moved into an endgame where
black is easily winning. |
|
| Sep-27-12 | | whiteshark: and that's it: <39...Qxh3+ 40.Kxh3 hxg3+ 41.Kg2 gxf2+ 42.Kf1 Rh1+>, a forced line. |
|
| Sep-27-12 | | tarek1: This one looks quite simple to me :
<39...Qxh3+!!> Beautiful queen sacrifice, White has to accept or lose the rook without compensation. <40.Kxh3 hxg3+>
Here giving the counter-sacrifice <41.Qxh6 Kxh6> is probably the best white has
but results in a lost endgame : White is an exchange down,
but above all his his queenside pawns are falling with the plan Rd8, followed by a rook invasion on d2 or d1. Let's if White can escape by simply defending
<41.Kg2 gxf2+ 42.Kxf2> Here <42.Kf3> loses to <42...f1Q+> and <42.Kf1> transposes into <42.Kxf2> after <42...Rh1+> <42...Rh2+ 43.Ke3 Rxd2 44.Kxd2> and White is an exchange AND a pawn down in this endgame, then losing. |
|
| Sep-27-12 | | poszvald: I do not know if there is something better, but I think this secures the game for black: 39, ..Qxh3+
40, Kxh3 hxg3+
41, Kg2 Rh2+
42, Kf1or3 Rxf2+
43, Qxf2 gxf2  as black has rook + pawn for bishop, which should be enough. |
|
| Sep-27-12 | | Tiggler: A Queen sac on Friday. White's relatively best defense is 41.Qxh6+, but it leads to a hopeless B v R endgame, even though the pawns are equal. The main line leads to a worse version of the same ending. |

| Sep-27-12 | | Abulherar: Black's best move is:39...Qxh3+!
1)40.Kxh3 hxg3+ 41.Qxh6+ Kxh6 42.fxg3....
Black has the upper hand because he can take white's Qside pawns.
2)40.Kxh3 hxg3+ 41.Kg2 gxf2+ 42.Kxf2 Rh2+ 43.Ke3 Rxd2 44.Bxd2....
Black also has the upper hand because he has a pawn advantage. |
|
| Sep-27-12 | | CHESSTTCAMPS: Black is up a full exchange, but white can impede progress with 40.Qd7+ Kg6 41.Qd2, inviting repetition of the position. Black's progress is also stymied by the pinned h-pawn. Therefore, black should simplify with 39... Qxh3+! 40.Kxh3 hxg3+ forcing a won ending:
A) 41.Qxh6+ Kxh6 42.gh Rd8 and white can't stop the penetration of the rook and loss of queen-side pawns. B) 41.Kg2 gxf2+ 42.Kxf2 (Kf3? f1=Q+) Rh2+ 43.K moves Rxd2 winning. B.1) 42.Kf1 Rh1+ 43.Kxf2 Rh2+ offers no improvement.
Time for review... |
|
| Sep-27-12 | | Patriot: 39...Qxh3+ 40.Kxh3 hxg3+ 41.Kg2 gxf2+ 42.Kxf2 Rh2+ (42.Kf1 Rh1+ 43.Kxf2 transposes; 43.Ke2? f1=Q+ ) 43.Kf3 Rxd2 44.Bxd2 That looks pretty easy. |

 | | agb2002: Black has a rook for a bishop.
The white king looks very unsafe and 39... Qxh3+ removes the only defender, 40.Kxh3 hxg3+: A) 41.Kg2 gxf2+
A.1) 42.Kxf2 Rh2+ 43.Ke3 (43.Ke1 Rg1#) 43... Rxd2 - + [R+P vs B]. A.2) 42.Kf1 Rh1+ 43.Kxf2 Rh2+ transposes to A.1.
A.3) 42.Kf3 f1=Q+, etc.
B) 41.Qxh6+ Kxh6 42.fxg3 Rg5 43.Kg2 Kf5 44.Kf3 e5 and Black should win the ending. |
|
| Sep-27-12 | | Djoker: 39. ...Qxh3+
40. Kxh3 hxg3+
41. Kg2 (Qxh6+ Kxh6 ) gxf2+ (I think Rh2+ will also lead to same outcome but gxf2+ is faster)
A.
42. Kxf2 Rxh2+ picking up queen
B.
42. Kf1 Rh1+
43. Kxf2 is A.(only other move is Ke2 which is even worse) |
|
| Sep-27-12 | | pericles of athens: bam! nailed it. I'm getting Wednesday
puzzles now? Must be doing something
right. |
|
| Sep-27-12 | | PinnedPiece: Well this was more like a Monday. I Started straight off with checking the most forceful move on the board--Queen sac QxR+ Things rolled easily on from there. Going to be B v. R in short order. The only question, would this be so visible OTB?
I think today the answer for most of us would be "Yes". . |
|
| Sep-27-12 | | Castleinthesky: I agree about the Mondayish comments, as this is my first full-credit of the week. |
|
| Sep-27-12 | | MATTYMONKEES: I agree with the comments about difficulty level also. I'm a total amateur and this was also my first "full-credit," so to speak, of the week. |

Sep-27-12
 | | Oxspawn: Hardly any time to look at this today; so, from the hip… <39…. Qxh3+
40. Kxh3 hxg+
If 41. Qxh6+ Kxh6
42. gxh> this leaves black with rook for bishop and a passed central pawn, and I suggest a won ending (even if I am playing it). If. <41. Kg2 Rh2+
42. Kf3 (or f1) Rxf2+> and the queen must sacrifice itself, this time leaving black with the same piece advantage and one extra pawn. I expect there are other more challenging responses from white, but I am happy with this five minute analysis (in a fool’s paradise no doubt) and I will post it. I am, however, suspicious as the puzzles seem to be getting easier as the week goes on… like those scenes in Alien where you think Sigourney has killed the beast… and it is about to plunge through the ceiling.
At least I avoided my first thought…
<39. hxg
40. Qxh6++ hello monster> |
|
Sep-27-12
| | Oxspawn: Well, I can join in the celebrations. It seems the monster is indeed dead. The trouble with Chessgames is there is always a sequel tomorrow, and the monster is back bigger and badder than ever... Just when you thought it was safe to go back on the chessboard... |
|
| Sep-27-12 | | James D Flynn: I have now played over the game hoping to see Blacks winning plan after 31.Qxh6+ instead White played the pathetic 31.Kg2 |
|
Sep-27-12
 | | gawain: I saw 39... Qxh3+ 40...hxg3+ and then 41... Rh2+. It seemed pretty straightforward. I am happy to know that my choice for move 41 is as good as the game continuation. |

 | | chrisowen: I findings oh, eg ok in good variation for black after in hut approach b6 and bb7 to seeking brave the assualt free queene2 instead of 10.e5 sustenance in c3 and after nd7 knight idea nf1 or h4 im thinking Fischer used too employ a variation c3 and d4, c4 ok in effect weaken sent d3 and provides in g5 unsettling the balance in blacks favour position takes on an appearance in French tinkling the ivories white knights geed up flowing g4 and h6 allow ground for constricting play black has long gains as white is forced to part with his involvement rookd1 for knightd7 thus righting off record in kindly fashion it rooks have room for maneovreing kingside, the tool in 39...Qxh3 check in removing rook fix h3+ king taking back hxg3+ opens lines to xray rookh6 beats down file stop Ol i shine open *nose in front* g2 or entrance in h6 black will abruptly be another exchange up riding g8 survey it easy win chaplain c3- fire it her in d2 queens it hot in:
39...Qxh3+ each free dead 40.Kxh3 hxg3+ rook check extra 41.Kg2 rh2+ king bolt 42.Kf3 Rxf2+ open difficult route am i liking g1 then genial f1n+! |

 | | paulalbert: Just got back from all day business meetings and looked at this. I immediately went for the game continuation, so in agreement with many comments that this seemed easy for a Thursday. |
|
| Sep-27-12 | | Ratt Boy: Thank you, chrisowen, for clearing it all up for me. |
|
| Sep-27-12 | | TheBish: Hracek vs A Kveinys, 1992 Black to play (39...?) "Medium", Black is up a rook for a bishop. This doesn't seem like it should be too hard, being ahead material, but there is at least one pitfall to avoid: Not 39...hxg3?? 40. Qxh6#. So how to convert our advantage? 39...Qxh3+! 40. Kxh3 hxg3+ 41. Kg2
White could return the queen with 41. Qxh6+ Kxh6 42. fxg3, but Black would have an elementary win, up an exchange with a passed e-pawn. 41...gxf2+!
Black could also win with 41...Rh2+ 42. Kg1 gxf2+! 43. Kxh2 f1=N+, simplifying to an exchange-up endgame. 42. Kf1 Rh1+ 43. Kxf2 Rh2+ 44. Ke3 Rxd2 45. Bxd2
Black will have no trouble winning this endgame. |
|
| Sep-28-12 | | kevin86: White must allow black to queen or lose his own queen.I like how the pawn climbs the ladder with discovered check. |
