| Oct-01-14 | | Cheapo by the Dozen: 15 ... d6 looks necessary. White has decent attacking chances whether he plays things straight up or actually goes for the f5/f6 gambit, but surely Black's chances in that line are better than they were after the game move. |

I had the same idea as you - <18.Nf6+ ...> - with the "main" line <18. ... gxf6? 19.Qg5+ ...> & <20.Qf5 ... > pp.! I am quite happy that I have not been alone! |

 | | Penguincw: I missed the typically Bxh7+ sacrifice (although I did consider it). What I did have in mind was 18.Nf6+, which still gets the job done, but after 18...Kh8, the win is a lot longer. After 19.Qh5 h6 20.Qf5 g6 21.Qh3 h5, white can attempt to sneak up to h6, or try to crash through on g6/h5. |

 | | patzer2: Fritz indicates 13...Qc7? is the unlucky move that loses after 14. e5!  .Instead, 13...Qc5+! 14. Kh1 d6 = to  holds roughly equal. |

 | | doubledrooks: 18. Bxh7+ Kxh7 19. Qh5+ Kg8 20. Nf6+ gxf6 21. Qg4+ K moves 22. Rf3 and mate is coming up. |

| Oct-01-14 | | Cheapo by the Dozen: <gofer>,
In your line, the straightforward
14 ed Ng4
15 Qd2
seems to work for White. Changing your 13 ... d5 to 13 ... d6, however, might work for Black. I think we agree that pushing the d-pawn is pretty important. |
|
| Oct-01-14 | | jdc2: This type of mate is discussed in detail in Vukovic's "Art of Attack in Chess". I was able to see up to move 21, where instead I thought Rf3 first, which still works but takes a move longer. |

 | | playground player: Bxh7... just like puncturing a tire. |
|
| Oct-01-14 | | RookFile: I have no doubt that 18. Bxh7+ is the best and strongest move. It does seem like white's position is overwhelming. For example, if he does something simple like 18. Nxc7 Qxc7 19. Rc1, I'm sure this is 1-0 within 10 moves or so. White is fully mobilized and black's queenside is undeveloped. |

 | | kevin86: Pretty easy; the queen and rook steamroll the king on the g-and h files. |

 | | Longview: Interesting position. As has been pointed out, White has more space and better placement with only the Knight as the only unguarded piece so my eye gravitated there first. I considered Nxc7, N-e7 and N-f6+ but if K-h8 it is winning but seems drawn out and allows black to advance pawns, move the Knight back and frustrate the attack for a while. I then turned to the Bxh7+ which allowed the Queen to guard the Knight and this attack is a common method of opening the King's corner up. 19. Kxh7 allows what we saw with 20.Nf6+. 18. ...K-h8 is a failure that I missed the short mate on in my mental analysis. I thought the 19. Q-h5 would be frustrated by 19... g6 and missed the simple 20. Bxg6+ K-g7 21.Q-h7++. I kept wanting to bring the Knight into the battle and overlooked it. |

 | | LucB: This is a good one to remember; I was going to lift the rook (instead of checking with the knight) and mate on the h-file, but that LSB was guarding h3. We can learn something new everyday, even at my age! |
|
| Oct-01-14 | | BOSTER: <gofer:13...Qc5+ 14.Kh1 d5!>. <patzer2: Fritz 13...Qc5+ 14.Kh1 d6>. Let's try <greedy> 13...Qc5+ 14.Kh1 Nxe4(diagram).
click for larger view Is it safe? |
|
| Oct-01-14 | | waustad: Like <LucB> I hadn't considered the Qg5+ nuance from the original puzzle position. |
|
| Oct-01-14 | | JG27Pyth: Luc<I was going to lift the rook (instead of checking with the knight) and mate on the h-file, but that LSB was guarding h3.> I don't think d6 is the refutation of the rook lift. White replies with check from the N and mate follows (with the rook giving check from g3). I think black answers Rf3 with Qxd5 then if Rh3 f6 and I don't see how White mates. |

 | | laskereshevsky: At a first glance I saw ♗xh7+ ♔xh7 ♕h5+ ♔g8 ♘f6+ followed by ♕g4+ and ♖f3 its letal.... but maybe even to play ♘f6+ for first its a winning one.. |
|

| | patzer2: <Boster><13...Qc5+ 14.Kh1 Nxe4 Is it safe?> Fritz assesses it as slightly favorable to White after 15. Nxe4 Qxb5 16. Nd6 Qxb2 17. Qd5 (position below).
click for larger view Don't know if it's safe, but I wouldn't mind playing 17...Qf6 and trying to hold this position. |
|
| Oct-01-14 | | Doniez: At a first glance I decided to go for the Knight sac on f6, so to remove the defender pawn g7. The game was different but I think that my solution works as well. |
|

 | | whiteshark: A Bxh7+ combimation, pure and again consistently entertaining. |
|
Oct-01-14
| | LucB: <JG27Pyth> ... right... lift then check, or check then lift... works both ways. Thanks! |
|
| Oct-01-14 | | HowDoesTheHorsieMove: I got everything, except I went exf instead of Rf3. Checking with Stockfish, it still wins but not as cleanly. I'm going to call this a miss. |
|
| Oct-01-14 | | Cheapo by the Dozen: <BOSTER>'s line has Black up a pawn, and threatening both ... Nf2+, which wins the exchange, and Nxc3, which wins a piece. So White presumably needs to choose the continuation: 14 Nxe4 Qxb5
Off the top of my head, the main tries I see for White are 15 Nd6 and 15 Nf6+, and I don't see why he'd love the results of either of them. |
