| Jan-20-07 | | Fisheremon: <LoveThatJoker: I use neither board nor computer.
LTJ> Take my bow ! It could be greater in that manner to find intuitive moves (or sacs). My style's just to find original (or intuitive) solutions in order to understand Chess deeper. |
|
| Jan-20-07 | | LoveThatJoker: Well, Fisheremon, I commend you, man. You are a good analyst for a non-pro player. That is something great as it is already. I hope you realize that I am not afraid of stating a line and then having someone try to refute it. I am looking for truth in Chess too and if I am wrong it is because I have made a mistake and therefore it is my responsibility to acknowledge it and correct it. I do think I do a fairly decent job already as it is seeing as how I solve all these problems Blindfold, but it is not enough. I still make mistakes and this is something I cannot become complacent about. It is important not to make mistakes, so if I am ever wrong please point it out - as you have been - and I will admit to it - as I have been. And if you are ever wrong - just admit to it - and get stronger in the process! LTJ |

 | | pittpanther: <<pittpanther: A follow up to < epiph: no, ng6 doesn't work, because I think one of the key ideas behind ne6 is that it threatens the following beautiful combination: 30...Rxg7+ 31Rxg7 Qxh6+!! 32Kxh6 Bxf7 mates > What if black does not play 32 Kxh6 but rather plays Kg8? Can black weather the storm?>
32...Bxf7 is not even mate, as the black king escapes via g5. Forgive me if this is full of errors, as I haven't bothered to check it on a board, but rather than 30. Rxg7, the move I think is 30. Nxg7!, after which 30... Rxg7 31. Qxh6+!, and if black tries to decline with 31... Kg8, white forces him to take the queen with 32. Qh8+!! Kxh8 33. Bxf7+ Rh7 34. Rg8#>
I have also noticed that after 30. Rxg7 Rxg7 31. Qxh6 Kh8 that white has a brilliant win with 32 Bg6! he will mate with Qh8 and black is powerless to stop it. If he takes the bishop with the rook then Qh7 mates or if takes with the pawn then Qh8 followed by Qf8. This could almost be a Monday or Tuesday puzzle to find 32 Bg6!. |

|
| Dec-10-17 | | Cheapo by the Dozen: It was clear by elimination that the game move had to be answer, but I don't really see how the knight was poisoned. |

that black cannot simply ignore <29 Ne6> and that is most
of its beauty!

Yep, White wins the exchange AND has massive pressure on the g and h files... |

(29.Ne6 R:e6 30.fe6 Q:e5 31.Bg4)
(29...fe6 30.Bg6+ and mate)
30.Ng5+ Kh8 trying to find, whites next 31.Qf4? |
|
| Dec-10-17 | | Pasker: Cool tactic. The key theme here to remember is that Rxh6 followed by Qxh6 checkmate. The king has no flight square. |
|
| Dec-10-17 | | agb2002: White is one pawn down.
The white knight is on the queen's path to h6. This suggests Ng6, with the threat e5, and Ne6. The former is met with 29... fxg6, so 29.Ne6: A) 29... fxe6 (removes two defenders of g6 at once) 30.Bg6+ Bxg6 (30... Kh8 31.Rxh6+ gxh6 32.Qxh6#) 31.fxg6+ Kh8 32.Rxh6+ gxh6 33.Qxh6#. B) 29... Nb4 (a waiting move) 30.Rxg7+ Rxg7 (30... Kh8 31.Qxh6#) 31.Qxh6+ Kg8 (31... Kxh6 32.Bxf7#) 32.Qh8+ Kxh8 33.Bxf7+ Rh7 34.Rg8#. C) 29... g6 30.Qxh6+ Kxh6 31.Bxg6#.
D) 29... Qf6 (to keep the control of g6) 30.e5
D.1) 30... Qxe5 31.Rxg7+ as above.
D.2) 30... Qxf5 31.Ng5+ Kh8 (31... hxg5 32.Bg4+ wins the queen) 32.exd6 seems to win decisive material. E) 29... Rxe6 30.fxe6
E.1) 30... Qxe6 31.Bg4 Qa(b,c,d,f)6 32.Bf5+ Kh8 (32... g6 33.Qxh6#) 33.Rxh6+ gxh6 34.Qxh6#. E.2) 30... fxe6 31.Bxe6 (31.Rg5 Qf6 unclear) 31... Rxe8 32.Ra1 Nb4 33.Rxa5 + - [R vs n+p] and the better position. |
|
| Dec-10-17 | | Cheapo by the Dozen: Ack. <agb2002> showed that the poisoning of White's knight is pretty simple. Silly me. |
|
| Dec-10-17 | | morfishine: With Black's Knight unwisely side tracked all the way over to <a2>, of course White can storm Black's king side with impunity ***** |
|
| Dec-10-17 | | malt: <29.Ne6 Qf6>, had tried 30.e5
30...Bc6+ spoils the fun 31.Bf3 B:f3+ 32.R:f3 Q:e5 |
|
| Dec-10-17 | | patzer2: In today's Sunday puzzle (29. ?), White is a pawn down but all of his pieces are strongly posted and attacking the weak, castled Black King position. Moreover, the Black Knight is out of play on the Queenside and the Black King is under protected. So an all out assault by White on the Kingside looks promising. The target square for the attack is g6, which is attacked four times by White and defended four times by Black. However, an immediate attack on g6 with 29. Ng6? fails as Black turns the tables and steals the win after 29. Ng6? fxg6 30. Bxg6+ Bxg6 31. fxg6+ Rxg6 -+ (-8.07 @ 37 ply, Stockfish 8). So the attack on g6 must be more subtle. The correct method and the solution to today's Sunday puzzle is 29. Ne6! +- (+4.52 @ 30 ply, Stockfish 8), which obstructs Black's access to g6 and gives White superior numbers attacking that critical square. Black's strongest defense to 29. Ne6! is the game move 29...Rxe6 which obviously loses to 30. fxe6 +- (+4.76 @ 32 ply, Stockfish 8). Black's second best defense is 29...Qf6 which loses to 30. Ng5+ Kh8 31. Qf4 Rc6 32. e5 +- (+8.29 @ 31 ply, Stockfish 8). P.S.: For an early improvement, the Stockfish 8 suggestion 9...h5 ⩱ (-0.37 @ 34 ply) appears to give Black clearly better counter attacking chances than the game move 9..0-0 = (-0.14 @ 33 ply). Indeed, an initial run of Stockfish 8 to 34 ply shows Black winning after
9...h5 10.Na4 Be7 11.c4 h4 12.Nc3 d4 13.Nd5 Kf8 14.Qb3 Qd7 15.Nxe7 Qxe7 16.Bxc6 bxc6 17.Qa4 Bh3 18.Rfe1 Rh6 19.Qa3 Re8 20.e3 Qg5 21.Qxa7 Kg8 22.Qxc5 hxg3 23.fxg3 Bf5 24.Nf3 Qh5 25.Nh4 g5 26.Nxf5 Qxh2+ 27.Kf1 Qh3+ 28.Kg1 Qxf5 29.exd4 Qxd3 -+ (-7.06 @ 33 ply). White can probably improve here, but the Stockfish analysis is sufficient to demonstrate 9...h5 gives Black a clear advantage. |

|
| Dec-10-17 | | cormier: 1. Nf3 c5 2. g3 Nc6 3. Bg2 d5 4. O-O e5 5. d3 Be7 6. e4 d4 7. Nbd2 Be6 8. Nc4 and the right move is 8 ...f6 |
|
| Dec-10-17 | | Howard: The way Agzamov died was quite, quite sad! Death by drowning, in fact. |
|
| Dec-10-17 | | JohnDMaster: I am proud of myself for not being lazy and solving this puzzle, I think Ne6 threatens Ng5!! so I figured black was forced to play Rxe6 and the rest plays itself |
|
| Dec-10-17 | | njchess: OMG! I got it. Block the rook/queen from protecting the h pawn, no matter the cost. Pretty sick combination from White. |
|
| Dec-10-17 | | 5hrsolver: 29. Ne6 Nb4 30. Bg6+ fxg6 31. Ng5+ Kh8 32. Nf7+ Kh7 33. Rxh6+ gxh6 34. Qxh6# Or 29. Ne6 Rd7 30. Rxg7+ Rxg7 31. Qxh6+ Kxh6 32. Bg6# Or 29. Ne6 Rd7 30. Rxg7+ Rxg7 31. Qxh6+ Kg8 32. Bg6 fxg6 33. Qh8+ Kf7 34. Qf8# |
|
| Dec-11-17 | | stst: close to time-out, give one plausible variation:
29.Bg6+ fxB
30.Ne6 (then follow some variations) one being gxf5
31.Rxg7+ RxR
32.Qxh6+ Kg8
33.Qb8+ Kf7
34.NxR(g) QxN
35.Rh7 pins the Q |
|
| Dec-11-17 | | Patriot: <agb2002> That's some nice analysis! Line B) 34.Rg8# is not a valid move though. Maybe the quiet 32.f6 here? |
|
| Dec-11-17 | | agb2002: <Patriot: <agb2002> That's some nice analysis! Line B) 34.Rg8# is not a valid move though. Maybe the quiet 32.f6 here?> The residual image strikes again.
In this case, White has another way to force the black king backwards: 30.Bg6+ fxg6 31.Ng5+ Kh8 32.Nf7+ Bxf7 (or 32... Kh7) 33.Rxh6+ gxh6 34.Qxh6#. I should have revised my original line and then would hace chosen this one. |
|
| Dec-11-17 | | Patriot: <agb2002> <The residual image strikes again.> It happens to everyone from time to time. I like that line! |
