| Aug-05-17 | | AlicesKnight: I saw that Bxg7 was key before Black could block with ...e5, but thought Black might try for ...f5 and ...Ne6 after 15.Qh6 - but now I don't think it helps much. |

| Aug-05-17 | | whiteshark: The sacrifice at g7 or g2 is intended to demolish the opponent's King-side pawn structure, setting up possible mating attacks, decisive win of material or won endgame positions. --> Game Collection: 70d_middlegame SACS on g7 (of g2) |

| Aug-05-17 | | agb2002: The prosaic 14.e5 is met with 14... g6 followed by dxe5. This suggests 14.Bxg7: A) 14... Kxg7 15.Qh6+
A.1) 15... Kg8 16.e5 f5 17.gxf6
A.1.a) 17... Kf7 18.Qxh7+ Ke8 19.Bg6+ Rf7 20.Qxf7#. A.1.b) 17... Rf7 18.Rhg1+ Kh8 19.Rg7 Nf8 20.Rxf7 wins. A.1.c) 17... Nxf6 18.exf6 Rxf6 19.Qxh7+ Kf8 20.Rhg1 Ke8 (20... bxc3 21.Q(R)g8#) 21.Rg8+ Bf8 22.Bg6+ Rxg6 23.Qxg6+ and 24.Ne4 + - [R+N+P vs 2b]. A.2) 15... Kh8 16.e5 f5 17.gxf6
A.2.a) 17... Rf7 18.Bxe7 Q(R)xe7 19.exd6 followed by Ne4 with an extra pawn and attack. A.2.b) 17... Nxf6 18.exf6 Rf7 19.fxe7 wins a piece. B) 14... bxc3 15.e5 f5(6) (15... cxb2+ 16.Kb1 doesn't seem to change anything) 16.gxf6 looks winning (16... Nxf6 17.exf6 Bxf6 18.Qxh7+ Kf7 19.Bf6+ Ke7 20.Bxf8+ Kxf8 21.Qf7#). C) 14... e5 15.Bxf8 wins decisive material. |

| Aug-05-17 | | ChessHigherCat: Corrected annotation (my nemesis):
I think it probably starts with 14. Bxg7 because otherwise black could play g6 and/or e5. If 14...dxc3 15. e5 threatening Qxh7#
15..f5 16. g takes en passant and it's got to be over soon with the open g file and attack on h7 If 14...Kxg7 15. Qh6+ Kh8 16. e5 and same as above. If 14...f5 15. g takes en passant again, although I here I think there might be a better solution. |

| Aug-05-17 | | malt: 14.e5 is met with ...g6 15.Qf3 de5
Looks like 14.B:g7 K:g7 15.e5 Rh8 16.Ne4 N:e5 17.Qh6+ Kg8 18.Nf6+ B:f6 19.gf6 Qf8 20.Qg5+ Ng6 21.h5 Qe8 22.hg6 fg6 I was thinking maybe 23.Rh6 Ra7 |

| Aug-05-17 | | wtpy: Got the first two moves.Saw 14.. Nc5 15. Qh6 but did not take into account Re8. When confronted with an unseen defensive resource in a POD, I try to figure out next moves and if I get them will usually give myself credit or at least partial credit for the puzzle. Sadly, on this occasion I went down the
rabbit hole of 17 Bf6, even though I saw 17..Bf8. I thought white could back out with Qh5,that black would have to lose time moving his queen and that the destruction of black's kingside pawns would be sufficient for white to win. However 18..Qa5 probably puts the kabosh on that theory, as it probably forces 19 Nb1 to save the knight and after 19 ..Qa2 black's attack may well arrive first. |

| Aug-05-17 | | wtpy: I wonder if Vlastimil Babula is the son of B. Babalula who perhaps arrived at Ellis Island and like Vito Corleone was forced to change his name. |
|
| Aug-05-17 | | wtpy: And in the above post, I dont mean maybe. |

 | | PawnSac: < 7he5haman: 18.Bc4 was the penultimate blow - did Black really never have time for, or could not get away with, the intermezzo Nxd3+?
Maybe because of the eventual Rxd3-Bxe5 motif, whereby the black d-pawn is pinned against the black queen, and white threatens Qg7# > No time for Nxd3 black is scrambling to get defense for white squares. But you answered your own question pretty much. I think 13. Bd3 < Ne5 > 14. Bxe5 dxe5 15. Bxb5 Qb6 16. Ba4 Qxf2 looks about equal and much more solid for black. |

| Aug-05-17 | | ChessHigherCat: <malt: Gone down the wrong rabbit hole, with 14.B:g7 K:g7 15.e5 < 15.Qh6+ > Yes, I went down the 15. Qh6+ rabbit hole and was surprised not to see you there. It's easy to get the wrong address when you're late for a very important date. |

| Aug-05-17 | | RandomVisitor: <wtpy>Be-bop-ba-bula, 13...Ne5 I mean, maybe.. |
|
| Aug-05-17 | | wtpy: RV, I was begin to think that there were nothing but
philistenes at this site. And Ne5 looks like a definite improvement. |
|
| Aug-05-17 | | RandomVisitor: <wtpy>Since the 10.Qh5 attack does not seem to produce immediate results, maybe he can do better in the long run with quiet positional play and 10.Qd2:

| Aug-05-17 | | ChessHigherCat: If Vlastimil's middle name were Robert, you could call him V. Bob Babula. |
|
| Aug-05-17 | | drollere: i looked at variations around something like
14. Bxg7 Kxg7
15. Qh6+ Kg8
16. e5 f5
17. g5xf6 e.p. etc.
i didn't see Nc5 as a defense but in that case why not just take the KR without Qh6? (of course, Qh6 threatens Bf6 and mate). white is up the exchange and will shortly have 2 Rs bearing on the black K. |

| Aug-05-17 | | wtpy: CHcat, Nice. My faith in the chessgames.com folks fondness for name jokes and classic music has now been restored. Sadly my faith in many other things is still lacking. |
|
| Aug-05-17 | | Leole: Here is my solution:
16.Rhg1!(instead of Ne2)bxc3 17.g6!+-
However, I consider the text a more practical, hence better solution. It wins without any risks. |

| Aug-05-17 | | RandomVisitor: After 9...0-0 white has Qd2, f4, Be2 and a3:

| Aug-06-17 | | patzer2: <RV> Great analysis of the improvement 13...Ne5 =, as well as suggestions for an earlier improvement for White with 13. a3 ⩲ to ± or 10. Qd2 ±. From Black's perspective, I think it would be wise to follow the strong preference of strong players and ditch 6...Nc6 in favor of the popular move 6...h6. |
