 | | Penguincw: Happy November everyone! It's also Movember. If you can, grow a moustache (FWIW, I have one on right now :{D ). Okay, too much info, sorry.
Anyway, since it's Sunday, I didn't bother to spend much time on it. I came up with 14.Bxb7+ Kc7 15.Bf4, but after 15...Qe6, the white queen is actually trapped. Looking forward to tomorrow (Monday). |

 | | patzer2: For today's Sunday puzzle solution, 14. Qxf7! forces a winning combination where White gets four passed pawns for a Bishop. My failed attempt was 14. Bxb7+ which fizzles out to a near level position after 14... Kc7 15. Bxe7 Bxh5 16. Ba6 Rb8 17. Bd6+ Qxd6! 18. exd6+ Kxd6 19. Kd2 c5 = to  . Black's first mistake was 11...0-0-0?!
Instead, 11...c6 = as in V Gashimov vs Gelfand, 2008 keeps it level. The decisive error was 13...bg4?
Instead, 13...g6 holds on with only a slight White edge after 14. Bxb7+ Qxb7 15. Rxb7 gxh5 16. Rxe7 Rd7 17. Bf6 Rg8 18. g3 Kc7 19. Kd2 Rb8 20. Ra1 c5 21. a4 a5 22. Bg5 Kc6 23. Rxd7 Bxd7 24. Bf6 Bg4 25. Be7 Rb7 26. Bg5 Kd7 27. Kc1  . |

 | | OhioChessFan: This is unusual for me, but I got this Sunday very quickly. Like <Penguin> I usually don't spend much time on them before giving up. I don't think I could have conducted the Pawns to victory so effortlessly though. |
|
| Nov-01-15 | | Mehem: Black can also defend by 14... bxa6. After 15.Qxe7 Qxe7 16.Bxe7 Rd7 17.Bd6 Rb7 18.Rxb7 Kxb7

White must struggle with the OCB endgame inconveniences. |
|
| Nov-01-15 | | morfishine: Weird for a Sunday: <14.Qxf7> is the only move, yet there's 41 more moves after that. Odd |
|
| Nov-01-15 | | wooden nickel: The played line leads to a very instructive and impressing endgame which is hard to evaluate that many moves ahead. I was trying to make 14.Rxb7 work, Black could lose at the drop of a hat but by best play only draws.
14.Rxb7 Bxh5 15.Rb3+ Kc7 16.Rb7+ Kc8 17.Rb3+ Kc7 18.Rb7+ Kc8 draw

| Nov-01-15 | | Pinkerton: 17...Rd7 would have been |
|
| Nov-01-15 | | znsprdx: As beautiful as Qxf7 idea is- it is far from obvious that there is any more than a draw Where's the win after 32....Rxe5 seems odds on of a lot of non-consecutive 3-fold repetitions |
|
| Nov-01-15 | | PJs Studio: I love how white can't play 54. Kg7?? because of Rxh7+! and black draws! |
|
| Nov-01-15 | | PJs Studio: Skip that ^ I forgot about the g3 pawn, which provides white an easy win. (Still, I like Sutovsky's 54.Ke5 much better) |
|
| Nov-01-15 | | varishnakov: 14.Rxb7 Bxh5 15.Rb3+ Kc7 16.Bxe7 (16.R-b7+ draw) 16...Qxe7 (16...R-b8 17.B-d6+) 17.R-b7+ K-c8 18.Rxe7+ I missed it. Mine led to level material if black plays correctly on move 16. |

| | patzer2: <znsprdx><Where's the win after 32....Rxe5 seems odds on of a lot of non-consecutive 3-fold repetitions> Indeed, 32...Rxe5  (+0.75 @ 21 depth, Deep Fritz 14) makes the win problematic. However, White can avoid this problem two moves earlier with the stronger 30. f4  (+2.42 @ 24 depth, Deep Fritz 14). |

 | | thegoodanarchist: I got the first 20 moves but instead of 34.Kg2 I had 34.Kf1. I guess I get no credit... |
|
Nov-01-15
 | | Jimfromprovidence: A fun game to review with plenty of alternative lines to analyze. For example, 47 Rd7+ looks like a clear improvement, forcing 47...Kc5 and taking black's king right out of the defense of white's pawn advance.

 | | agb2002: The material is identical.
Black threatens 14... Bxh5.
The black queen looks overburdened with the defense of the bishops and b7. This suggests 14.Bxb7+: A) 14... Qxb7 15.Qxg4+ Qd7 16.Qa4
A.1) 16... Bxg5 17.Qa6+ and mate next.
A.2) 16... Qc7 17.Qa6+ Kd7 18.Rb7 Bxg5 19.Rxc7+ Kxc7 20.Qxa7+ Ke8 21.0-0 + - [Q+2P vs R+B]. A.3) 16... Rde(f,g)8 17.Qa6+ Kc7 (17... Kd8 18.Rb8+ and mate next) 18.Rb7+ wins. B) 14... Kc7 15.Qh4
B.1) 15... Rb8 16.Bxe7 Rxb7 17.Bd6+ Kc8 18.Rxb7 Kxb7 (18... Qxb7 19.Qxg4+ wins a piece) 19.0-0 and White has an extra pawn with the better position. B.2) 15... Bxg5 16.Qxg5 Rb8 17.Qf4
B.2.a) 17... Rxb7 18.e6+ Kd8 (18... Qd6 19.Rxb7+ wins the queen) 19.exd7 Rxb1+ 20.Kd2 Rxh1 21.Qb8+ Kxd7 22.Qxh8 Rxh2 23.Qxg7 Rxg2 24.Qxf7+ + - [Q vs R+B]. B.2.b) 17... Qe6 18.0-0 Rxb7 19.Rxb7+ Kxb7 20.Rb1+ Ka8 21.Qb4 Qd7 and White doesn't seem to have enough compensation for the bishop. -----
Another option is 14.Qxf7:
A) 14... Bxg5 15.Rxb7 Qxf7 16.Rxf7+ Kb8 17.0-0 Ka8 (17... Bh6 18.Kb1+ Ka8 19.Bb7+ Kb8 20.Bxc6#) 18.Rb1 Rb8 19.Bb7+ Rxb7 20.Rbxb7 A.1) 20... Rb8 21.Rxa7#.
A.2) 20... Rg8 21.Rxa7+ Kb8 22.Rfb7+ Kc8 23.Rxg7 Rxg7 24.Rxg7 h6 25.h4 wins decisive material. A.3) 20... Bh6 21.Rxa7+ Kb8 22.Rfb7+ Kc8 23.Re7 Kb8 (23... Kd8 24.e6 and the threat 25.Red7+ followed by 26.Ra8# looks winning) 24.e6 looks winning [R+3P vs B+B]. B) 14... bxa6 15.Qxe7 Qxe7 16.Bxe7 Rd7 17.Bd6 Rb7 18.0-0 with an extra pawn and a much better position but opposite colored bishops. -----
I think I'd play 14.Qxf7. |
|
| Nov-01-15 | | dfcx: Black about to play 14...Bxh5. For white, I like 14.Bxb7+, this is the only forcing move. 14...Qxb7 15.Rxb7 Bxh5 16.Rxe7
14...Kb8 15.Bxc6+ Kc7 16.Bxd7 Bxh7 17.Bxe7 Rxd7
14...Kc7 15.Qh4
White wins at least a pawn. |
|
| Nov-01-15 | | gofer: I (like <wooden nickel>) went down the wrong path... <14 Rxb7 Bxh5>
<15 Bb3+ Kc7>
<16 Bxe7! ...>
click for larger viewAt this point black cannot
a) take the bishop...
17 ... Qxe7
18 Rb7+ Kc8
19 Rxe7+ Kb8
20 O-O
b) or try to extracate its queen and attack...
17 ... Qg4
18 Rb7+ Kc8
19 Rb4+ Kd7
20 Rxg4
c) or simply get its queen to safety!
17 ... Qf5
18 Rb7+ Kc8
19 O-O
<17 ... Rb8>
<18 Bd6+ Qxd6> (forced!) <19 exd6+ Kxd6>
<20 O-O ...>
click for larger viewI think this is a draw, so the game line is significantly better.
Still this is quite a nice alternative... |
