 | | agb2002: White has a queen and the bishop pair for two rooks, a bishop, a knight and a pawn. Black threatens 23... gxf4.
The rook on d8 prevents 23.Qd6#. This suggests 23.Bc8+ Kf6 (23... Rxc8 or 23... Rd7 24.Qd6#) 24.Qxd4+ A) 24... Ke7 25.Qxg7 (25.Qc5+ Ke8 (25... Kf6 26.Qxc6+ Rd6 27.Qxd6#) 26.Qxc6+ also seems to win) A.1) 25... gxf4 26.Qe5+ Kf8 27.Qxh8+ Ke7 28.Qe5+ Kf8 29.Bb7, etc. A.2) 25... Rxc8 26.Qe5+ Kd7 27.Qd6+ Ke8 28.Bxg5 f6 29.Qxf6 wins. B) 24... Kg6 25.Bf5+ Kh6 26.Bxg5+ Kxg5 27.Qxg7+ Kf4 (27... Kh4 28.Qh6#) 28.Qd4+ Kg5 (28... Kf3 29.Qe3#) 29.f4+ Kh4 (29... Kh6 30.Qf6#) 30.Qf2+ (or 30.Qf6+ Kh3 31.Qh6#) 30... Kh3 31.g5# or 31.Qg3#. |

| Jul-24-14 | | morfishine: <23.Bc8+> is a nice deflection which Black cannot accept due to 23...Rxc8 24.Qd6# Black can only run, but there is no sanctuary, even if he tosses material 23.Bc8+ Kf6 24.Qxd4+ Kg6 25.Bf5+ Kh6
<26.Qe3> Black has no good reply to this 26...f6 27.h4 Rhe8 28.hxg5+ fxg5 29.Bxg5#

 | | Once: There is something fascinating about the concept of imbalances in chess. Here we have a classic tussle of queen versus two rooks. One against several. And that calls to mind the great battles of Bruce Lee versus the prison guards in Enter the Dragon, of the Bride versus the Crazy 88, of King Kong versus ... well, just about everybody. This is the position after 13...0-0-0
click for larger viewAnd this is how the game finished after 29... resigns 
click for larger viewYup, those two black rooks have stayed stuck in place for the entire second half of the game. But worse that that. Their entire contribution to the first half was as 50% of the move 13...0-0-0. Meanwhile the white queen terrorises the queenside, the centre and then delivers mate over on the kingside. But don't all the books say that a queen is worth less than two rooks? Eight or nine points of royal tush versus ten points of butch stone ramparts? Perhaps. But only if the rooks actually have anything to do. In this game, the two rooks suffered because they had no targets whilst white had a fun time torturing the exposed black king. |

| Jul-24-14 | | Ratt Boy: Looked at it; had no idear. Bxg5+ didn't look too promising. An hour later, it's time to goto work; I'll give it another quick look. Oh, hey! Bc8+! Nice to give the brain a rest sometimes. |

| | Once: Incidentally the chessgames bio for today's winner, Heather Richards, says simply "She is a WIM." Which is concise almost to the point of being enigmatic. We can imagine such a sentence being written in a far future dystopia where mankind is barely hanging on. Mad Max IV maybe. He is just a raggedy man and she is a wim. Now I come to think of it, should WIM stand for "Woman's International Mistress" instead of "Woman's International Master"? Hmm. Okay. Maybe not. |

Thanks chessgames.com community for their explanations. |

 | | Penguincw: Wow. I didn't even consider 1.Bc8. :| |
|
| Jul-24-14 | | awfulhangover: I, like others here found Bc8+, but in a real game otb? No. |

 | | kevin86: I found the first few moves, but doubt I could finish it. |
|
| Jul-24-14 | | estrick: I've heard that in master games where a queen versus two rooks imbalance occurs, the player with the queen wins more often than the player with the rook. |
|
| Jul-24-14 | | Castleinthesky: I almost finished it, so I earned about a .9 in credit. I'll cut the tip off of the gold star. |

| Jul-24-14 | | BOSTER: Looking at this pos., black to play 22...
click for larger view
and understanding that the white are building the mating net,playing 22.g4,
black should not dream how to catch the smart woman playing g5 in hope Bxg5,
he should play in-between move 22...Nf3+, and after 23 the white king moved 23...Ne5 interrupting the communication between Bishop f4 and d6 square. If 24.Bxe5 Bxe5 25.Qxc6+ Rd6 (or Bd6) black can continue to play. And now we are here.

| Jul-24-14 | | Ratt Boy: <chrisowen> once again tries to pass the Turing Test. Failure though it is, it's a valiant effort. |

 | | perfidious: <Ratt Boy> Turing Test or <Turgidity Test>? |
|
| Jul-24-14 | | PJs Studio: I got all the way to 28.Qd4+ and couldn't see the mate after 29.h4! So I chose 28.Qf6 (someone please tell me it ALSO works.) I know...it probably doesn't. |
|
| Jul-24-14 | | Amarande: <PJs Studio> 28 Qf6 in fact works. Here the threat is 29 h3 (covering the g-pawn) followed by discovering mate by moving the Bishop to anywhere along the b1-h7 diagonal (except e4). Black's King is sealed in quite airtight - the only chance for escape would be through f3 and e2, but if 28 ... Kf3, then 29 Kf1 pins the King down (Black cannot counter this with 29 ... Rb8 because the Bishop covers b1, so 30 h3 Rb1+ fails to 31 Bxb1#). Even sacrificing a Rook outright appears to delay mate by at most four moves. (In both variations, it does not matter which Rook is chosen.) a) 28 Qf6 Re8 29 h3 Re6 30 Bxe6+ Ke4 31 Bf5+, forcing the King back to f4 (whereupon the main discovered mate happens at once) or f3 (whereupon 32 Kf1 and mate next move is unavoidable). b) 28 Qf6 Re8 29 h3 Re1+ 30 Kg2 Rg1+ 31 Kxg1, and mate next move. c) 28 Qf6 Re8 29 h3 Re1+ 30 Kg2 Re6 31 Bxe6+ Ke4 32 Bf5+, again with mate in two. d) 28 Qf6 Rg8 29 h3 Rxg4+ (not Rg6 30 Bxg6#) 30 Bxg4+ Ke4 31 Bf5+, etc. (The g4 pawn itself is actually superfluous to the mate, it only matters that g4 itself is covered.) |

| Jul-24-14 | | PJs Studio: Thanks Amarande. |
|
| Jul-24-14 | | Chess Dad: Here's what I see, but it's not a forced mate, so I'll go step by step and look to see Black's response.
23. Bc8+
A. 23. ... Rxc8 24. Qd6#
B. 23. ... Rd7 24. Bxd7+
C. 23. ... Kf6 24. Qxd4+
Now I'll see which of these paths black takes....
24. Qxd4+ Kg6 forced.
25. Bf5+ Kh6 forced.
26. Bxg5+ Kxg5 forced.
27. Qxg7+
I'll go that far and see black's move for 27.
27. ... Kf4
28. Qh6+
Whoops. I guess Qd4 was better. I'll look at the other comments to see why... [edit] I also see that 24. ... Kg6 wasn't the only move. I just didn't consider 24. ... Ke7 because of 25. Bxg5+. |
|
| Jul-24-14 | | Caissas Clown: Bc8 was easy to see. But my very first instinct was to look for a Rook to play Re1 check. |
|
| Jul-24-14 | | Mess With Da King: Chess Dad: in your line B the rook is pinned, so the queen mates next move as in line A |
|
| Jul-24-14 | | WhiteRook48: 23 Bc8+ with 23...RxB 24 Qd6#
Or 23...Kf6 24 QxNch Kg6 25 Bf5+ Kh6 25 Bxg5+
Which should be enough to carry the day. I'll not look further than that. |

| Jul-24-14 | | mccraw: <Once> i almost never post, but here's a belated Birthday Greetings. Hope it was a smashing one...
A little late, but please let me say how much i've enjoyed your chess commentaries over the years! Wit, imagination, and chess insight--a Very Rare Combination on these pages :-) |

 | | Bubo bubo: <Amarande> After 28.Qf6 Re8, White simply forces mate by 29.Bc2+ Kxg4 30.Bd1+ followed by Qh6#. |
|
| Jul-24-14 | | thegoldenband: <awfulhangover: I, like others here found Bc8+, but in a real game otb? No.> If you can find it in a puzzle position but not OTB, then you probably need to be more disciplined about systematically examining every single check and capture available to you, even if they look unlikely. I find that quiet moves are very hard to spot OTB, but forcing moves are there to be found as long as you make the effort to look for them and don't dismiss odd-looking moves out of hand. |
