 | | Penguincw: Those long last names though...
Anyway, I thought about sacrificing on c6 a couple of times, but that doesn't accumulate to anything. Not that I could come up with anything else. |
|
| Dec-05-15 | | Cheapo by the Dozen: Realistically, I would just have played Nc5, forcing ... Bc8, after which I probably would have taken the c6 pawn. |
|
| Dec-05-15 | | mel gibson: I saw this in under 10 seconds -
not bad for a "difficult" one. |
|
| Dec-05-15 | | diagonalley: <diagonalley> nul points :-( |
|
| Dec-05-15 | | patzer2: Spent over 10 minutes trying to make 21. Nc5 work before giving up on it. Finally, after exhausting other piece move possibilities, I found 21. d5!  . |
|
| Dec-05-15 | | kubbybulin: After several poor efforts this week I was determined to redeem myself tonight.
First I tried 21. Nc5 and 21. Ne5 to no avail. Ne5 only wins a pawn back as does Nc5. I think what led me to toying with 21. d5! was the constant assaulting of c6 in my previous attempts. I could only see 5 logical ways to defend c6 after 21. d5: I saw some ridiculous lines in here so I will weed them out and give only the critical lines for each: 21...Rd5 22. Bd5 cd5 23. Nc5 Bc8 and I like white a lot. 21...cd5 22. Rc7 Rd7 23. Rd7 Qd7 24. Nc5 wins
21...ed5 22. Re1 Qd7 23. Nc5 wins again
21...Rc8 22. d6 Qd7 23. Nc5 wins yet again
21... c5 22. d6 Qd7 23. (anybody wanna guess?) Nc5 |

| Dec-05-15 | | patzer2: For a Black improvement, Deep Fritz 14 indicates 17...a5 = is better than 17...Nf6 18. Nxf6  . And 18...gxf6 19. Nf4 puts up more resistance than 18...Qxf6 19. Qc5! . |
|
| Dec-05-15 | | morfishine: I didn't consider 21.d5 |
|
| Dec-05-15 | | whiteshark: Cute, the black ♕ is overloaded and almost immobile with protecting ♗b7 and ♖d8. Didn't see it, though. |
|
| Dec-05-15 | | MindCtrol9: I did not even try to solve it because there is no mate,then is not a puzzle to me. |
|
| Dec-05-15 | | Patriot: <<morfishine>: I didn't consider 21.d5> Neither did I. I looked at how the pieces are arranged and for those seeds of tactical destruction and thought 21.Ne5 was the way to go. But 21.d5 also makes light of this and it wasn't even on my radar.
Take a look at the position after 28.Nc7. I wondered at first why black didn't just go for 28...Rxa2? The answer (I think) is 29.Nxd5!. 29...exd5 30.Bxd5 Ra6 31.Bxc6 and black cannot re-capture due to the back rank. 29...Rxb2 30.Ne7+ wins the knight again because of the weak back rank. |
|
| Dec-05-15 | | Patriot: Also, after 28...Rxa2 29.Nxd5:
29...Kf8 30.Nc3 Ra6 31.Nxb5
The extra piece again wins. 31.Bxc6 may be best (trade down when ahead). |
|
| Dec-05-15 | | King.Arthur.Brazil: I saw 22.d5 directly as it is posted "difficult", cause you need to open the column for the white B and R, as black Rs are blocked (not connected yet). If exd5, 22.Re1 is a strong move, so I thought that's the way! The continuation is good, but I don't agree with 23.Rxd7?... weak! For me it seems better: 23.Qxb7! Rxc7, 24.Qxa8 Rb7 (threatening Qc7 and Ra7 to win the Q), but 25.Nc5! win! (25... Qxc5, Qxb7, 25... Qc7 26.Qxb7...). Black resign. |

| Dec-05-15 | | agb2002: White is one pawn down.
The black queen looks overburdened with the defense of the bishop and the rook on d8. After 21.Nc5 Bc8 22.Bxc6 Nxc6 23.Qxc6 Ra7 Black seems to hold. Another option is 21.d5:
A) 21... cxd5 22.Rc7 wins the bishop.
B) 21... exd5 22.Re1 Qd7 23.Nd5 wins the bishop.
C) 21... g6 22.dxc6 Bc8 23.c7 wins.
D) 21... Rc8 22.dxc6 wins decisive material. For example, 22... Bxc6 23.Bxc6 Nxc6 24.Rxc6 Rab8 25.Qxa6 + - [N+P]. |
|
| Dec-05-15 | | agb2002: I didn't consider 22... Rd7 because of 23.Qxb7 Rxc7 24.Qxa8 with a bishop for two pawns. Although the queen is momentarily out of play after 24... Qd8, the simple 25.Rc1 should lead to a won ending. |
|
| Dec-05-15 | | agb2002: <Patriot> Good to see you're back! |
|
| Dec-05-15 | | kevin86: A bit too hard 4 me! |
|
| Dec-05-15 | | thegoodanarchist: 21.? White to move and win
Tough puzzle. |
|
| Dec-05-15 | | Patriot: <agb2002> Thanks! I'll be here every now and then. Nice analysis, by the way! Line C) illustrates a key seed of tactical destruction--noticing the x-ray of Bg2 to Ra8! |
|
| Dec-05-15 | | Gerry84: Doesn't 30 Nxb5 win the black knight? Doesn't really matter as white is cruising now, but after taking the pawn there's a double threat of 31 Rc8# and 31 NxN... |
|
| Dec-05-15 | | Gerry84: Oops no, Ne2 kills that... |
|
| Dec-05-15 | | CHESSTTCAMPS: At the bargain price of a pawn, white has imposed a horribly cramped and passive position on black, which has a "tall pawn" and two pieces on their original squares. Black has no immediate threat, but may intend to evict and exchange the invading queen with a5 followed by Ra6. My first instinct was to play the natural Nc5, grabbing the hole and tightening the screws, but then I realized that with this big advantage, a sharper line is available. 21.d5! opens lines to facilitate the invasion. There is no safe way to take the pawn: A. 21... cxd5 22.Rc7 Rd7 23.Rxd7 Qxd7 (Nxd7 24.Qxb7 Rb8 25.Qc7 with a bishop for two pawns and control of c-file) 24.Nc5 Qe7 25.Qxb7 Qxb7 26.Nxb7 Nd7 (Ra7? 27.Rc1!) 27.Rc1 with a winning endgame. B. 21... Rxd5 22.Bxd5 exd5 (cxd5 23.Rc7) 23.Re1 Qd7 24.Nc5 wins. C. 21... exd5 22.Re1 Qd7 (Qf6/g5 23.Qxb7) 23.Nc5 wins D. 21... Nd7 22.Qxb7 wins
E. 21... c5 22.d6! Rxd6 23.Qxb7 Qxb7 24.Bxb7 Ra7 25.Rxc5! Rd8 (otherwise Rc8+) 26.Be4 is winning. F. 21... other 22.exf6 is crushing
Time for review.... |
|
| Dec-05-15 | | CHESSTTCAMPS: <Patriot:... I wondered at first why black didn't just go for 28...Rxa2? The answer (I think) is 29.Nxd5!.> Good point! |
|
| Dec-05-15 | | CHESSTTCAMPS: Of course line F should read F.dxc6 is crushing. |
