Like, are you kidding me? (Splat on e7.) |

 | | Penguincw: Normally if I'm one of the first puzzles solvers of the day, I like to make some comments in general, but I got none today. Sorry to those who actually read them. :) Back to this puzzle, OTB, I would've played 16.Ng5, but I had thoughts of sacrificing on e6. I also had a thought of an exchange sac on b1, but coming with check, I disregarded it. |

| Nov-15-15 | | nalinw: I got Rxb1 with the idea of trapping the queen - but didn't see the defense ... f5 .
No wonder the problem seemed far too easy for a Sunday! |
|
| Nov-15-15 | | patzer2: For today's Sunday puzzle, 16. Rxb1!! leads to a surprise attack which forces Black to succumb to a decisive attack on his King in order to save his Queen. For an improvement for Black, instead of <10...Qxf6?!>, I'd start with Ian Roger's refinement 10... gxf6 in his win in Schmittdiel vs I Rogers, 1991. Black's game takes a big turn for the worse with <12...Bxc2? 13. Rc1  > (+1.63 @ 21 depth, Deep Fritz 14). Instead, 12..h6 13. 0-0-0  (0.69 @ 21 depth) keeps hope alive. White's follow-up is strong and clearly winning. However, Deep Fritz 14 indicates an even stronger follow-up than <23. Ne5 > is 23. Nd2! when play might continue 23...Nd7 (23... a6 24. Re1 ) 24. Qf3+ Nf6 25. Bxf6 gxf6 26. Qxf6+ Ke8 27. Re1+ Qe7 28. Qxh8+ Kd7 29. Rxe7+ Bxe7 30. Qxa8 with mate-in-nine. |

 | | al wazir: White missed a more elegant finish: 22. Bg8+ Be7 (22...Kd7 23 Qe6#; 22...Ke8 23. Qe8#) 23. Re1 Rxg8 24. Bxe7 Qd7 25. Bg5+ Kf8 26. Ne5, with 26. Ng6+ to follow. But I missed the whole combination from 18. Bd3 on. |

 | | agb2002: White is one pawn down.
The obvious 16.Ne5, trying Nxf7 to expose the black king and to take advantage of the uneasy position of the black queen, is met with 16... Qe4, threatening 17... Qxh1# and 17... Qxe2+, stopping White's attack. This suggests 16.Rxb1 Qxb1+ 17.Kg2 Qg6 18.Bd3 f5 (18... Qf6 19.Bg5 traps the queen) 19.Bxf5: A) 19... Qf6 20.Bg5
A.1) 20... Qf7 21.Bxe6
A.1.a) 21... Qc7 22.Re1
A.1.a.i) 22... Nd7 23.Bxd7+ and mate soon (23... Kxd7 24.Qe6#; 23... Kf7 24.Qe6+ Kf8 25.Be7+ Bxe7 26.Qxe7+ Kg8 27.Be6#). A.1.a.ii) 22... Na6 23.Bd7+ is similar to A.1.a.i).
A.1.a.iii) 22... Kf8 23.Qe4, threatening 24.Qf5+, looks winning. For example, 23... Nd7 24.Qf5+ Nf6 (24... Ke8 25.Qf7#) 25.Bxf6 wins. Or 23... g6 24.Bh6+ Ke8 25.Bd7+ Kxd7 (25... Kd8 26.Bg5+ and mate next) 26.Qe6+ Kd8 27.Bg5+ Be7 28.Bxe7+ is a massacre. A.1.b) 21... Qf8 22.Bf5+ Be7 (22... Kf7 23.Qe6#) 23.Re1 wins since Black cannot defend e7. A.1.c) 21... Qg6 22.Bf5+ wins the queen.
A.2) 20... Qf8 21.Qxe6+ Be7 22.Qd8+ (or 22.Re1 as in A.1.b) 22... Kf7 (22... Bd8 23.Qxd8+ Kf7 24.Ne5+ Kg8 25.Be6#) 23.Ne6+ Kg8 24.Be6#. B) 19... Qf7 20.Bxe6 Qe7 (else Bc8+ followed by Bxb7, for example) 21.Bg5 looks similar or transposes to A. |

| | agb2002: For some reason I missed 22... Bxe1 but to my surprise it is Stockfish's option (Droidfish on a tablet). After 23.Bb3+ Kf8 24.Nxf1 Na6 25.Qf3+ Ke8 26.Qe4+ Kf8 27.Qf5+ Ke8 28.Qe6+ Kf8 29.Nd3 Black is defenseless against Bf4. |

| Nov-15-15 | | jith1207: <Penguincw>: Can you read your post again? You actually still made some comments in general :P |
|
| Nov-15-15 | | jith1207: Good Job to those who noticed the queen trap. My successful fluke this week ended today, hoping to start another one tomorrow. This is a wonderful puzzle all around, and I just love Chess for giving such surprise-full sequence of events just coming out of the opening! |
|
| Nov-15-15 | | jith1207: He is probably one of the players in the world with a positive score against Kasparov, where the latter never even scored a point or even a half of it against him. |
|
| Nov-15-15 | | TheFocus: <Wow! +2=0-0 against Kasparov! |
|
| Nov-15-15 | | morfishine: Best is <16...Rxb1> which has been described as a 'decoy' or 'deflection'. However, the primary theme centers on the idea that when you are ahead in development, trade pieces: the side who is behind in development, will soon have a hopeless position, which is what happened here: In the final position, Black's QR & QN never moved and his KR made one poor move *The sequence 12...bxc2 followed by 15...Bb1 seems suspect ***** |
|
| Nov-15-15 | | gofer: Today, we have a beuatiful forced sequence, it exchanges a rook for a bishop, two pawns
and a massive attack!
<16 Rxb1 Qxb1+>
<17 Kg2 Qg3>
<18 Bd3 f5>
<19 Bxf5 ...>
The queen is again forced to move, for the thrid time in a four moves, but finally she has
a small amount of choice...
19 ... Qf6
20 Bg5+ Qf7 (Qf8 Qxe6+ )
21 Bxe6 Qc7 (Qf8 Bf5+ )
22 a3
The king is caught in the centre, the bishop has to give up its defence of Re1 and that spells the end for black... 19 ... Qf7
20 Ng5 Qf6
21 Nxe6
The knight threatens all sorts of mayhem. It all looks horrible for black, not immediately losing, but definitely losing! ~~~
I got the first 6 moves... ...does that count!? |

 | | Richard Taylor: I played this game over a few days ago and I still couldn't remember what Murray played! I knew it involved a Q trap. I cant even recall what chess book it was in. Good game by Chandler.
Chandler rarely plays chess now but he runs Gambit Books and organises or helps to organise tournaments here in Auckland NZ and there is another one starting on the 2nd of Jan 2016. Already there are 6 GMs in the Open and some FMs etc There is also other sections. Links http://www.newzealandchess.co.nz/
http://www.newzealandchess.co.nz/Ve... The two top players are 1. Nigel Short and 2. Gawain Jones. I'm playing but I will be shredded into nothingness...Perhaps I should have played in the other tourney: the Major Open which has mostly lower ranked players but it wont be easy for players of my (Club and general blunderer category) level or ranking. |

| | Richard Taylor: I remember where I found it, it was from the chess column he used to write in the mid 70s to 80s and I played it over at random. It was in the New Zealand Listener May 6th 1984. On move 10...Qxf6
Chandler says:
"Consistent, though objectively 10...gxf6 is better. Rogers had assumed that I did not know some recent analysis which runs 11. g4 Bg6 12. Bg5? Bxc2! 13. Qe2 Qg6 with advantage to Black." But Chandler did. His annotations of his own and GM games in The Listener were excellent and I kept a lot of them and rediscovered them. There is one where he saw a possible sacrifice against Karpov (then the World Champion) Karpov vs Chandler, 1983 The article was called
'The One That Got Away' as after the game they couldn't find a defence to Chandler's postulated Q sac. (As noted by Benzol and others). |
|
| Nov-15-15 | | dfcx: saw the first 3 moves but did not see Bxf5.
It's hard. |
|
| Nov-15-15 | | thegoodanarchist: Black leaves his king in the center and is duly flogged for his indiscretion. |
|
| Nov-15-15 | | shubhamthebest: great puzzle....i found Rxb1!! with the idea of trapping the queen n finished on trapping the king lol |
|
| Nov-15-15 | | Everett: Another lesson in pawn snatching in the opening. One better be a profound and thorough calculator, especially as Black,to get away with material-over-development in the opening. |
|
| Nov-16-15 | | CHESSTTCAMPS: White is trailing by a pawn, but leading in development, with three minor pieces active in the center. The black queen is almost trapped, but not quite, ready to meet 16.Ne5 with Qe4, forcing an exchange of queens that relieves pressure. This suggests an exchange sac to remove the piece that enables possibility: 16.Rxb1! Qxb1+ 17.Kg2 Qg6 18.Ne5 Qf6 19.Bg5!! Qxg5 20.Nxf7 Qf6 (Kxf7?? 21.Qxe6+ Kf8 22.Qf7#) 21.Nxh8 Nd7 22.Bxe6 O-O-O 23.Nf7 and white is up a pawn with a strong position. All I have time for.... |
|
| Nov-16-15 | | CHESSTTCAMPS: Overly focused on the f7 sac, I missed something simpler. |
|
Jul-11-21
 | | FSR: Rogers' 23...Be7 is minutely better than 23...Nd7 as in J Polgar vs T Halasz, 1985. But Black's position is way beyond saving. |
