| Jan-13-11 | | gofer: I have looked at a few alternatives (Qxg4, Bxg4, Qxf2+) and they are all pretty bad for black, so lets go for broke! <14 ... Qxh1+>
<15 Bxh1 Rxh1+>
<16 Ke2 O-O-O>
This all looks forced and pretty safe for black. The king is caught in the centre of the board with now where safe to run.
Now white needs to avoid the discovered check, but this is really very difficult to do! 17 Ke3 Nxe5 looks to be fine for black!
17 Nd5 Nxe5 18 Kc3 Rxd5 looks to be fine for black Bb2 Rh3+ and Kb2 g6!
17 Kd3 Nxe5+ 18 Ke4 Nxg4
Okay there is probably something for white to fight a bit longer... ...but its time to check! |

14...Qxh1+ 15 Bxh1 Rxh1+ ..."
Far from obvious! I'll say- took me half an hour to find the best line, which (using the reversed position in your diagram) is (1)... Ng6+ (2) Kd3, Ree1 (3) Kc3 Rad1 trapping the Queen and emerging a peice up. Phew! Premature resignation indeed. I doubt very much I'd have found the win over the board- there are dozens of false trails and traps. |

 | | agb2002: The material is even.
White threatens 15.Rxh5 and eventually f4-f5.
If the queen escapes then 15.Rxh8 drops a rook. Therefore, 14... Qxh1+ 15.Bxh1 Rxh1+ 16.Kd2 0-0-0: A) 17.Ne4 Nb6+
A.1) 18.Kc3 Na4#.
A.2) 18.Nd6 cxd6 19.exd6 Rxd6+ 20.Ke3 Nd5+ 21.Kf3 (21.Ke4 Nc3+; 21.Kd2(3,4) Nf4+) Rg1 with the threat 21... Bxg4+ (21.Qe4 Bxg4+ 21.Qxg4 Rxg4). A.3) 18.Ke3 Rh3+ 19.f3 (otherwise 19... Rxc3) Bxg4 with the threat 20... Rxf3+. B) 17.Bb2 Nxe5+ 18.Ke3 Rh3+
B.1) 19.f3 Nc4+ and 20... Nxb2 - + [R+2B+P vs Q].
B.2) 19.Ke(f)4 Nc4 20.Rb1 Nxb2 21.Rxb2 Rxc3 - + [R+B+N+P vs Q]. C) 17.Ke3 Nxe5
C.1) 18.f3 Rh3 with the threats 19... Rxf3+, 19... Nxf3, 19... Nxg4+ and 19... Bxg4. C.2) 18.Ke(f)4 Nxg4 with enough material compensation for the queen and attack against the white king. |

| Jan-13-11 | | 1.e4effort: call me a chicken, but for me i'd rather get my Knight to a more stately square with this move. Say 14...Nxe5. The aim of that would be a deflection, hoping for 15.Qxe5, then start an onslaught with 15...Qxh1+ 16.Bxh1...Rxh1+ and then the Q can't run interference from her post at e5. But the more I look at this, the more it becomes obvious that ain't gonna work. So, the heck with the Knight move, just start with the Q sac with 14...Qxh1. There has to be something i'm missing, but i'm on the clock, I gotta scoot, so I'll peek. Crap - the white K moves after the R+ and then black castles long. That's killer!! Didn't see that far ahead -'specially didn't see the K moving. To me - that's not the best. But then again, neither am I!! |
|
| Jan-13-11 | | Patriot: It quickly became clear that 14...Qxh1+ is the only option for black. Counter-attacking with 14...Bxg4 15.Rxh4 Bxe2 16.Rxh8 is bad for black. 14...Qxg4 15.Bxc6+ bxc6 16.Rxh8 also looks bad for black. Although I was uncertain how this would end, 14...Qxh1+ 15.Bxh1 Rxh1+ 16.Kd2 seems completely forced. Then I got hung up as what black should do next and realized that perhaps just 16...O-O-O is threatening enough. OTB it would be a mistake to try and calculate this out from move 16 since 14...Qxh1+ is clearly best. Move 13 is a critical move where black needed to be confident he wasn't just losing to a skewer. |
|
| Jan-13-11 | | NewLine: You think black has still work to do in the final position? That white could play on and put some resistance and check black's attacking skills? Well how about having your king in the middle of a mine field, when a bomb might come off at any corner, seems to be the correct call to stay put and resign... |

 | | kevin86: Much more subtle than yesterday;the exposed white king is a goner. |
|
| Jan-13-11 | | CHESSTTCAMPS: In this middlegame position, material is even, but black has the initiative and a safer king. Already the die is cast: black has committed to give up the queen for rook and bishop with a very strong attack against the exposed white king. It took me a while to see that there is even a plausible alternative, but after 14... Qxg4? 15.Rxh8 (Qxg4? Rxh1+ wins a pawn) Qxg2, black has only a pawn for the exchange and very little pressure on white's king. Therefore, 14... Qxh1+ 15.Bxh1 Rxh1+ 16.Kd2 (Qf1 leaves white a piece down) O-O-O is almost a no-brainer. A discovered check is threatened, the WK is caught in a crossfire of rooks, the e-pawn must fall, and white's undeveloped queenside is a mess. Avoiding black's active pieces is an impossible task: A) 17.Ke3 Nxe5 18.f3 Bc4 19.Qg2 Re1+ 20.Kf4 Ng6+ 21.Kg3 (Kg5 Be7#) Be7 22.Bb2 Bh4+ 23.Kh2 Rh8 24.Rxe1 Bf2+! 25.Qh3 Rxh3+ 26.Kxh3 Bxe1 wins. A.1) 18.Bb2 Bxg4 19.Rxh1 Bxe2 20.Kxe2 Nc4 leaves black 2 pawns up with the initiative. A.2) 19.Qf2 Rh3 leaves the f-pawn and WK defenseless. A.3) 20.Kf2 Rxc1! 21.Rxc1 Rd2+ wins.
B) 17.Nd1 Nxe5+ followed by 18... R8xd1 wins.
C) 17.Bb2 Nxe5+ 18.Ke3 Rh3+ 19.Kf4 Bd6 20.Ke4 Bxg4 wins quickly. D) 17.Ne4 Bc4 18.Qe3 Nf6+ 19.Kc3 Nd5+ wins the WQ.

 | | Phony Benoni: Thanks for all the fine analysis, folks. I obviously wasn't seeing anything last night. There is an interesting principle involved, after <16.kd2>: 
click for larger viewShould black continue the attack by castling or a knight move? The former should be the top candidate move, because you know you'll have to castle at some point, but you don't yet know the best square for the knight. It's the same principle as the old opening chestnut about moving knights before biahops because you generally know where the knights will go, but the bishops have more options depending on the developing position. Of course, you can't blindly play play 16...0-0-0 with some analysis, like you play 1.e4 e5 2.Nf3. But castling should probably be the move you consider first. |
|
| Jan-13-11 | | Patriot: I can see that I made a mistake in the line <14...Qxg4 15.Bxc6+ bxc6 16.Rxh8 also looks bad for black.> 15.Bxc6 is not check, which changes it completely. It should be <14...Qxg4 15.Rxh8 Qxg2>. I saw this line first and thought I found a better line but was looking at the wrong position. |

| Jan-13-11 | | skemup: what about 17 Bb2?
If white want endgame, better remove black rook.. |

| Jan-13-11 | | chesskidnate: <skemup> 17... Nc5+ 18.Ke3 Rh3+ 19.Kf4 g5+ 20.Kxg5 Bh6+ 21.Kf6 Nd7# |
|
| Jan-13-11 | | CHESSTTCAMPS: <Phony Benoni:> <Should black continue the attack by castling or a knight move? The former should be the top candidate move,..> In this case the answer is particularly clear cut - the knight belongs on e5 where it hits 3 weak light squares, c4, f3 and g4. Therefore 16... O-O-O is correct, after which Nxe5(+) can't be prevented. |

White resigned after move 16. . |
|
| Jan-13-11 | | Zkid: White could definitely have played a few more moves but some experience with these positions(successful attacking, K in center, etc) will tell you just how hopeless they are for the defender - besides a lost position it is harder for the defender to find good moves than the attacker. I stopped my analysis after 16...0-0-0 because it's clearly winning and there are no alternatives anyway. Wouldn't have blamed white for playing on the few moves he'd last but I certainly don't think resigning was premature. |

| Jan-13-11 | | M.Hassan: "Medium" Black to move 14...?
Materials are even.
Black has no choice other than attacking or else, he will loose a Rook. so:14...........Qxh1+
15.Bxh1 Rxh1+
16.Kd2 0-0-0 (Make ready to check again by d Rook)
17.Ne4 Bxg4 (with the hope that ....Qxg4 18.Nxe5+ forking the Queen)
18.Qe3 Nf6+
19.Kc3 Nd5+
and White Queen is lost
