| Jul-19-06 | | The17thPawn: Nice mating combo. I was wondering if black could hold with 17...f5 allowing the queen into the game if white captures en passant? |
|
| Jul-19-06 | | RandomVisitor: <The17thPawn>17...f5 might do it, 17...Rc8 might be slightly better for Black. |
|
| Jul-19-06 | | think: I didn't get the puzzle, but working out the lines 18. ... Kxh6 and 18. ... gxh6 were instructive. |
|
Jul-19-06
 | | al wazir: I think 18. Bxh6 f5 19. Ng5+ also wins, but it's messy; there are a lot of alternatives for black. |
|
| Jul-19-06 | | chessmoron: 20...hxg5 not a good move at all. 20...Kh8 might be good but black still loses. E. Sharapov could be Maria Sharapova's dad if he has an 'a' after the 'v.' (all right, it sucks dirt!) |
|
| Jul-19-06 | | ReikiMaster: No holding back here - this is how Maria plays tennis. Any relation to white? |

| | al wazir: <chessmoron>: "Sharapova" is the female form of "Sharapov." Sharapov's wife, mother, or unmarried daughter or sister would be named Sharapova. |
|
| Jul-19-06 | | patzer2: For today's puzzle solution, White initiates a demolition of pawn structure combination with 18. Bxh6!! However, before jumping into it, Black might be wise to calculate the two key side lines 18... Kxh6 19. Qh3+ Kg6
20. Nh4+ Kg5 21. f4+ Nxf4 22. Rg3+ Kh5 23. Qg4+ Kh6 24. Qxg7+ Kh5 25. Qh7# and
18... gxh6 19. Ng5+ Kh8 20. Rh3 Qxe5 21. Rxh6+ Kg7 22. Rh7+ Kg8 23. Nxf7+ Kxh7 24. Nxe5  . Also, Black can put up more resistance with 20...Kh8!?, but White seems to have just enough for an endgame win after 20... Kh8 21. Nxe6 Nxf6 22. Nxc7 Nxg4 23. Nxa8 Rxa8 24. Rc3 Nd4 25. Rxc5 Ne2+ 26. Kh1 Rf8 27. f3 Rf7 28. Rc8+ Kg7 (+1.72 @ 15 depth, Fritz 8). |
|
| Jul-19-06 | | Fezzik: Nice!
I missed this, thinking that after 18.Ng5+? Black had to take. Of course he didn't and would have had an longer game than after 18.Bh6! I think 18.Ng5 would still have won, but it would have been much more difficult. |
|
| Jul-19-06 | | pawn52: I figured out the solution Bxh6, but I couldn't figure out the contiuation to the game. |
|
| Jul-19-06 | | pebble767: I got 18.Bxh6 but I didn't realize 18...f5 so I didn't calculated that line =( |
|
| Jul-19-06 | | mig55: Maybe Sharapov didn't figure out the solution neither after not taking? |
|
| Jul-19-06 | | jahhaj: I don't think you have to calculate the lines if Black refuses to accept the sacrifice. Just a waste of mental effort. Of course you do have to calculate should the sacrifice be accepted. The two key moves I think are 19.Qh3+ and 20.Rh3 respectively in the first and second lines that <patzer2> gives. Quite a long and difficult calculation for Wednesday. |

 | | Honza Cervenka: <patzer2> After 18... Kxh6 19. Qh3+ Kg6 20. Nh4+ Kg5 (20...Kh7 21.Ng6+ Kxg6 22.Rg3# or 21...Kg8 22.Qh8#) I was calculating different line: 21.Rg3+ Kf4 22.Re1 (quiet move, now 23.Qg4# is threatening) 22...Nxe5 (22...f5 23.Ng6#; 22...Nf6 23.Ng6+ fxg6 24.Qh4+ Kf5 25.Qg5#) 23.Ng6+ fxg6 (23...Nxg6 24.Qg4#) 24.Qh4+ Kf5 (24...Ng4 25.Qxg4#) 25.Qg5#. |

Nxa8 Rxa8 24. Rc3 Nd4 25. Rxc5 Ne2+ 26. Kh1 Rf8 27. f3 Rf7 28. Rc8+ Kg7 (+1.72 @ 15 depth, Fritz 8).> I couldn't find anything clearly winning for White in the line with 20. ... Kh8, and I am gratified that Fritz couldn't either. The line given by <patzer2> is certainly promising for White, but not nearly as clear as the game continuation. (After Black's 20th move, White has mate in four.) For a player of Timoshenko's strength, 20. ... hxg5 is a surprisingly weak move that surrenders all chances for continued resistance. |
|
| Jul-19-06 | | outplayer: I saw the posibility of 18.Bxh6! but didn't analyze it well. I would like someone to analyze the 18.Ng5+!? line with their strong computers. |
|
| Jul-19-06 | | DexterGordon: <patzer2> and <Peligroso Patzer>, what is Black's best in the 20. ... Kh8 line after 21.Rh3? I'm looking at 21...Nxf6 and 21...Ne5 but have neither board nor chess engine to help me! |
|
| Jul-19-06 | | patzer2: <Honza Cervenka> Thanks for pointing out that <quiet move> possibility. <Dexter Gordon> I gave what I found as the best line after 20...Kh8 and a long search with Fritz 8 in my previous post. It's not an easy endgame win, or without drawing possibilities, but I believe it's White's best shot. |
|
| Jul-19-06 | | patzer2: <Peligroso Patzer> Indeed, 20...Kh8 is the move Black should have played, as it makes the win at best difficult and at worst unclear. However, IMO the Fritz assessment as just enough for an endgame win after 20...Kh8 21. Nxe6 is probably correct. |
|
| Jul-19-06 | | Marmot PFL: Got it very quickly as Ra3-h3 is too obvious to miss, and the Bc1 targets h6. <Indeed, 20...Kh8 is the move Black should have played, as it makes the win at best difficult and at worst unclear. However, IMO the Fritz assessment as just enough for an endgame win after 20...Kh8 21. Nxe6 is probably correct.> That is an easy endgame win after 21.Ne6 Nf6 22. Nc7 Ng4 23. Na8 Ra8 24.Rc3 etc. Rooks are much stronger than knights in open ending positions and white has too many pawns. |
|
| Jul-19-06 | | RonB52734: I was pretty well convinced that 18.Ng5+ was the solution, but after 18. Ng5+ Kg8 it looks very unclear to me. |
|
| Jul-19-06 | | kevin86: I looked at Bxh6 BEFORE I looked at Ng5+ but I settled on the latter. If the sac is accepted,it's gravy-but on declining it,theposition is unclear. |
|
| Jul-19-06 | | YouRang: Bah! I hastily went with 18. Ng5+, thinking it was a clearance sac to bring the rook to h3 after 18...hxg5 19. Qh5+, but it doesn't close all of Black's get-away squares. The best I can do is force a draw. |

That could explain why Sharapov is notorious for squeeling and groaning at 100 dB while making moves. Must be something in the family. |
|
| Jul-19-06 | | Chess Classics: <YouRang> I did the same thing...after 18. Ng5+ I had 18...hxg5 19. Qh5+ Kg8 20. Rh3 not seeing that the king could escape with f7-f6. Oh well. Regards,
