 | | al wazir: <makaveli52> (and <cjrubiks>): I didn't think it would take 14 moves, but Fritz and I are in agreement: it's a win. Note that the solution to yesterday's problem was a combination that netted white a piece, and that was considered enough to win. There is no rule that we have to find a path to checkmate, though I concede that that's more elegant. |

| Jun-10-06 | | you vs yourself: I came frighteningly close to solving my first saturday puzzle. I saw 29.Rxe5+ fxe5 30.f6+ Kxf6 31.Ne8+ Ke7 32.Qg5+ Then I figured if black plays 32...f6, the play continues 33.Qxf6+ KxN 34.Rd8# I totally ignored black's response, 32...Kf8, in the 31.Ne8+ line. Either way, black is lost. But I can't claim that I solved today's puzzle because I didn't see all possible moves for black; and sometimes that one move which is missed in the analysis of a position could end up losing the game. |
|
| Jun-10-06 | | Fezzik: Ok, I give. Why was this a Saturday puzzle?
I spent about three minutes trying to decide between 31.Rd6+ and 31.Qf5+ before deciding they both win fairly trivially. I preferred 31.Rd6, but decided that Black would probably resign after 30.f6+ anyway. Again, why was this a Saturday puzzle? Did I miss something? |
|
| Jun-10-06 | | Fezzik: BTW, you vs yourself,
I'd give you full credit for finding the win in this case. Sure, your 31st was inefficient, but you found the basic winning idea and were brave enough to sac a rook and pawn for it. Give yourself credit! (Whaddya think, cg.com?) |
|
| Jun-10-06 | | you vs yourself: <Fezzik: I'd give you full credit for finding the win in this case.> Thanks! In the last post, I was just motivating myself for tomorrow's puzzle. If I feel like I solved today's puzzle, then tomorrow I might do the same even if I missed another easy line in a winning position. Eventually, it'll become a habit that could let easy wins slip way. So, I'll leave the feeling of incompleteness as it is and come back tomorrow even more motivated to check all the possible lines before looking at the solution:-) |
|
| Jun-10-06 | | dzechiel: Got this one quickly. The rook sac and f6+ are so forcing that it makes finding the main line very easy in this problem. |
|
| Jun-10-06 | | dzechiel: <Fezzik: Ok, I give. Why was this a Saturday puzzle?> The puzzles are posted at midnight Eastern time for the next day. Those of us on the west coast see the new problem at 9:00p Friday evening, but it's still a Saturday puzzle. |
|
| Jun-10-06 | | jahhaj: I agree, easy for Saturday. I saw the 31.Rd6+ version but 31.Qf5+ is a wonderful move. |
|
| Jun-10-06 | | charms: nice avatar, jahhaj... I like the lewis chessmen. |
|
| Jun-10-06 | | awfulhangover: It's mate in 9! 1. Rxe5+ fxe5 2.f5-f6+ Ke7xf6 3.Qg4-f5+ Kf6-e7 4.Qf5xe5+ Qc4-e6 5.Ng7-f5+ Ke7-e8 6.Qe5xc7 Qe6xa2+ 7.Kb1xa2 b4-b3+ 8.Ka2-a1 and 9.Rd1-d8# |
|
| Jun-10-06 | | dakgootje: Ahhhh im tired... therefor it took much longer that it would've taken normally, but still i solved it. Only thing was that i calculated around every variation (of the ones i did calculate which were quite a lot) around 3 times as i forgot whether the previous time i had concluded it was a win for white or not... So it took me 3 times as long as normally... easier then most of the saturdays i think |
|
| Jun-10-06 | | jahhaj: <charms> Thanks, I'm keen on them as well. In fact I had a replica set made out of resin as a kid. It was one of cg.com's standard avatars, I was surprised no-one else had grabbed it. I would have preferred one of the berserkers chewing his shield though.

| Jun-10-06 | | wolverine199: I think this was the first Saturday puzzle i was able to solve :D |
|
| Jun-10-06 | | Halldor: Missed 31.♕f5+!! - My line was: 31.♘e8+ ♔e7 32.♕g5+ ♔f8 33.♘xc7 ♕xc7 34.♖d8+ ♕xd8 35.♕xd8+ with an easily won position, I liked the rhythm
in this line.
(Thought 31.♖d6+ to be rather routine but a sound move, didn't analyse it though.) |
|
| Jun-10-06 | | kevin86: A spectacular finish! White combines an epaulette mat with a back row mate!! If 31...♔xg7 32 ♕g5+ ♔f8 or h8 33 ♖d8# or if 31...♔e7 32 ♕e5+ ♔f8 (or ♕e6 costs the queen) 33 ♖d8# |
|
| Jun-10-06 | | Milo: I had al wazir's finish. |
|
| Jun-10-06 | | The17thPawn: Only my second Saturday ever. <Al Wazir> you were definitely in my head on this one. I had the Rd6+ line as my solution as well. I don't think its as pretty as Navara's solution but it works. |
|
| Jun-10-06 | | drnooo: a series of forcing moves is a series of forcing moves: the rook check at d6 is just as good here, absolute stranglehold, once I saw that did not look further. Still it is odd that Fritz apparently did not look at the queen check leading to an even better finish. |
|
| Jun-10-06 | | Fezzik: drnooo,
Fritz missed 31.Qf5? Did you have it looking for just one line? I could see a computer preferring 31.Rd6+ to 31.Qf5 because the former doesn't drop a piece (the materialistic @#$@#%!s that they are), but not to see it at all? That seems strange. |
|
| Jun-10-06 | | cotdt: no, navarra's line works best. |
|
| Jun-11-06 | | notyetagm: <Honza Cervenka: Another pretty game of Czech number one.> Yes, a brilliant win by Navara. I really like how this guy plays chess. I absolutely adore his victory over Svidler from the Olympiad. His winning move in that game is 40 ♖x♗! and if 40 ... ♕x♖?, then White (Navara) executes an exquisite mate in 5 using the queen and knight working perfectly together. Also, since Navara has had great league results (6/6 in the 4NCL!), someone on his forum said that Navara will be rated 2713(!) on the next rating list. |
|
| Jun-16-06 | | Mameluk: From an interview with Czech olympionics: Which of your olympic games do you find your best? Navara: ´Maybe Navara-Kozul game, because I demonstrated great preparation and understanding, which happens seldom to me (mainly the preparation part). Mainly Zbynek Hracek is responsible, because he recommended this line to me.´ This game is not only about final combination, but even analyzing with Fritz, Navara´s game looks flawless. And Kozul played this line already few times. |
|
| Jun-16-06 | | euripides: <Mameluk> yes, this was the line that helped Kozul win the European championship this year. Navara's calm play reminds me of Leko's better games against the Sicilian. |
|
| Jun-21-06 | | patzer2: White initiates the first of three sham sacrifices with 29. Rxe5+! to force the King into position for a mating attack. In the final position, it's mate after 31...Kxg7 32. Qg5+ Kf8 33. Rd8#. |
|
Jul-01-06
 | | hesyrett: The position after 30...Kxf6 appeared in Shelby Lyman's syndicated chess column on Friday, June 30, 2006. Not having seen the game, I went for 31. Rd6+ because it either wins the Queen or mates. Note that Black can't retake the Knight after 31. Rd6+ Qe6 32. Nxe6 on account of mate in two. But 31. Qf5+, though less convincing, persuaded Kozul to resign! |
