| Apr-03-15 | | gofer: <diagonalley>: nul points Quite. This was way beyond me. I tried to force Rxd7 to work, but got no where. I tried to force Qf7+ & Qxg7, but got no where... |
|
| Apr-03-15 | | Oxspawn: We come to this site for a variety of reasons. For me, (who started 16. Nf7) at this level chess is a spectator sport. I would not think about trying to run faster than Bolt, so why imagine I can outwit the masters. Play the game through and enjoy it.... And I did. Just about worked out why Kavelek resigned at this point, so earned myself a cup of tea and managed to make that myself (1. tea-bag to cup; 2. Boiling water on tea-bag; 3. wait a bit (zugzwang); 4. add milk (white to play); 5. stir. 1-0!) |

 | | OhioChessFan: I gave up quickly and played through the game. This one is so hard if you let me try it again immediately after playing it over, I still wouldn't get it. |

| Apr-03-15 | | morfishine: White is down a piece
Even after significant pruning, the resulting branches overtaxed my calculating/vision skill. Trying to cut-off the Black King's escape route prior to beginning the attack is too slow; However, we can have fun with a

<Oxspawn> You get full credit for your brilliant 5-move combination! Time fresh'n up my coffee :) ***** |

| Apr-03-15 | | wooden nickel: After 16.Qf7+ Kd8, then 17.Na5! puts Black's head in the noose, threatening Nb6... i.e.

hence 17... c5 was the last desperate try! |
|
| Apr-03-15 | | A.T PhoneHome: 16.Qf7+ Kd8 (forced for Black) 17.Na4 and that's where it ends for me. So no credit for me. But Velimirovic was a tactical monster at his best so I'm content with my try (for now)! Enjoy your day/night <kibitzers>! |

 | | Penguincw: Challenge for every Saturday puzzle: figure out the first move, and the opponent's response: 16.Qf7+ Kd8, I got. :) Correction: Whoops, I forgot that today is only a Friday (it feels like a Saturday since I have the day off). |

| Apr-03-15 | | MindCtrol9: Basic principles of chess where the piece sacrifice has the object of keeping the King in the center without castling.White develops his pieces keeping the initiative meanwhile Black is restranged to the defense. |

| Apr-03-15 | | whiteshark: Sorry, I'm having a bad Friday... |
|
| Apr-03-15 | | patzer2: Here's my look at Today's Friday puzzle game with Deep Fritz 14 and the Opening Explorer: <1. e4 d6 2. d4 Nf6 3. Nc3 e5> Inviting 4. dxe5 dxe5 5. Qxd8+ Kxd8 6. Nf3  . If Black wishes to avoid this and keep the ...e5 option open, then 3... Nbd7, which has as good a won-loss record as any move in the Opening Explorer (35% wins for Black to 41% wins for White), is a good alternative. <4. Nf3 Nbd7 5. Bc4 Be7 6. O-O c6 7. a4
Qc7 8. Qe2 Nb6> Perhaps the relatively untested Deep Fritz 14 recommendation 8... exd4 9. Nxd4 O-O = is worth testing here. <9. dxe5 dxe5>
Not 9... Nxc4?? 10. exf6 Bxf6 11. Qxc4  .
<10. Bxf7+!> This true demolition sacrifice sets the stage for the tactics that follow. <10...Kxf7 11. a5 Nbd7 12. Qc4+ Ke8 13. Ng5 Nf8 14. Rd1 Bd7?!> Black can improve his survival chances with 14... Bd6 when play might continue 15. Be3 h6 16. Rxd6 hxg5 17. Rad1 Be6 18. Rxe6+ Nxe6 19. Qxe6+
Qe7 20. Qxe7+ Kxe7 21. Bxg5 Rad8 22. Re1 when White's two extra pawns compensate for slightly more than the loss of the exchange. <15. Be3 Qc8?!> This loses immediately, but the alternatives aren't pretty. Black can put up more resistance with 15...h6 16. Nb5! Qd8 17. Qf7+ Kd8 18. Qxg7 hxg5 19. Qxh8 cxb5 20. Bxg5 N6h7 21. Bxe7+ Kxe7 22. Qg7+ Ke8 23. Qg7+ Ke8 24. Rd5 Be6 25. Rad1! Qc8  to (+1.51 @ 22 depth) <16. Qf7+ Kd8 17. Na4 c5> If 17... h6, then 18. Nb6 axb6 19. Bxb6+ .
If 17... b6, then 18. axb6 .
<18. Nxc5 Bxc5 19. Qxg7 Ng6 20. Bxc5 Nh5> If 20... Qxc5, then 21. Ne6+ .
<21. Be7+> This wins, but some winning alternatives are: 21. Qf7! Nhf4 22. Nxh7 Qc6 23. Rd6 Kc7 24. Rad1 Rad8 25. Rxc6+ . 21. Nf7+! Kc7 22. Bd6+ Kc6 23. Nxe5+ with a mating attack. <21... Kc7 22. Bd6+ Kc6 23. Qf7 Kb5 24. a6 bxa6 25. Qd5+ Kb6 26. c4> Also winning is 26. Qa5+! Kc6 27. Rd3 Be6 28. Qa4+ Kb6 29. Nxe6 a5 30. Qxa5+ Kc6 31. Qa4+ Kb6 32. Rb3#. <26... Qc6 27. Qa5+ Kb7 28. Bc5 Rac8 29. b4 Rhd8 30. Nf7 Rg8 31. Rd6 Ngf4 32. Rxc6 Rxg2+ 33. Kf1 Rxc6 34. Nd8+ Kc8 35. Nxc6 Bxc6 36. Bd6 1-0> |

 | | Fusilli: Starting with the bishop sac, white engages in an all out attack strategy. If it doesn't work, he'll lose. If it works, he'll win. More than a specific move sequence puzzle, it feels like an attack strategy puzzle. (If I had thought of it as such, instead of frantically look for the killing blow, maybe I would have done better at solving it.) Every move maximizes the poison in white's attack. I share <morf>'s experience: this <overtaxed my calculating/vision skill>. But the whole game is an attack gem. Perhaps more appropriate for GOTD than POTD, but again, who can come up with a pun for these players' names? (90+% of puns are based on the players' names, greatly biasing the selection of GOTDs... which is why <CG> should get rid of puns altogether). |
|
| Apr-03-15 | | kevin86: The king is chased to the other side and wins for white. |

 | | scormus: I can identify with all those who found this tough. Perhaps CG decided Good Friday deserved something special. I did find 16 Qf7+ OK, but after that I could not find my way and decided to play it through ..... and was really mpressed until move 20. I was surprised not to see <20 Qxf6+> which looks crushing. From then on I thought W made rather heavy weather of it, a shame after the superb attacking play that went before. |
|
| Apr-03-15 | | JimNorCal: <Oxspawn>: "Play the game through and enjoy it" Well said. I have no feelings of inadequacy that I couldn't solve this; only feelings of admiration for Velimirovic. What vision! What skill! What courage! |
|
| Apr-03-15 | | Isilimela: My computer (Li Chess) suggests 18. b4 (instead of 18. Nc5) with the nice point that 18 ... cxb4 19. Nb6! Also gives the following decisive line:
20.Qxf6+ Be7 21.Ne6+ Ke8 22.Ng7+ Kd8 23.Bb6+ axb6 24.Qxb6+ Qc7 25.Ne6+ Ke8 26.Nxc7+ Kf7 27.Rxd7 Rhc8 28.Nxa8 Rxa8 29.Qxb7 Re8 |
|
| Apr-03-15 | | Isilimela: And a quicker win at move 25.
25.Qb3+ Kc6 26.Ra5 Bg4 27.Rc5+ Kd7 28.Qf7+ Kd8 29.Bc7# |

| Apr-03-15 | | TheaN: I stopped after a while. I had a good tunnelvision on this puzzle, convinced that variations of Rxd7, Qf7+ and Bb6 were supposed to work. Neither worked, saw it all failing on one tempo and got frustrated. The idea with Na4! is beautiful. <CG> played it smart here though: in order to make this <difficult> they started on move 16, allowing all the variations others have sufficiently mentioned as well. On move 17, it would have been very different. |

<Well said. I have no feelings of inadequacy that I couldn't solve this; only feelings of admiration for Velimirovic. What vision! What skill! What courage!> You've nailed it <Oxspawn> and <JimNorCal>. I'm glad there are those imaginative players like Dragoljub Velimirovic and Mikhail Tal who want to enjoy first and THEN only worry about the result. Very often such players take us into new territory, playing with youthful visions in mind. I am very green in chess, it's very fresh interest for me. I go and give a try at Daily Puzzles and I am not ashamed of going wrong; only by going wrong can one truly learn and appreciate something new. I am happy that I can read the kibitzes of those who already know, they make my day. And, when the day ends, while you appreciate the rigid technique and logic behind chess it is a blessing to have those who just "have a go at something interesting". |
|
| Apr-03-15 | | agb2002: White has a pawn for a bishop.
My first idea is 16.Qf7+ Kd8 17.Na4, threatening 18.Nb6: A) 17... Qb8 18.Nb6
A.1) 18... axb6 19.Bxb6+ Kc8 20.Qxe7 Ng6 21.Qxg7 Rf8 (21... Ne8 22.Qxd7#) 22.Ne6 seems to win material due to 22... Bxe6 23.Qxf8+ Nxf8 24.Rd8#. A.2) 18... Rg8 19.Nxd7 N8xd7 (19... N6xd7 20.Qxg8 + -) 20.Ne6+ Kc8 21.Qxe7 Re8 22.Rxd7 wins (22... Rxe7 23.Rd8#; 22... Nxd7 23.Qxe8#). B) 17... b5 18.Nb6
B.1) 18... axb6 19.Bxb6+ Qc7 20.Bxc7+ Kxc7 21.Qxe7, etc. B.2) 18... Qb7 19.Nxa8 Qxa8 20.Qxg7 and White has a rook, two pawns and the better position for a bishop and a knight. For example, 20... Rg8 21.Nf7+ Ke8 22.Nd6+ Bxd6 23.Qxf6 Be7 24.Qxe5. C) 17... Rb8 18.Nb6 Qc7 19.Rxd7+ N6xd7 (19... N8xd7 20.Ne6#) 20.Rd1 C.1) 20... axb6 21.Bxb6 Qxb6 22.axb6 looks winning.
C.2) 20... h5 21.Nxd7 seems to win (21... Nxd7 22.Ne6+ Kc8 23.Nxc7). |
|
| Apr-03-15 | | mruknowwho: I was thinking 16. Rxd7 N6xd7 17. Qf7+ Kd8 18. Qxg7. |
|
| Apr-03-15 | | Gato: Latest Stockfish says 20 Qxf6+ mate in 14. |
|
| Apr-04-15 | | CHESSTTCAMPS: In this early middle-game position, white has a pawn for a bishop and a strong attack against the black king caught in the middle and pressure on the weakened light squares. If black did not have a Nf8, white would have 16.Qf7+ Kd8 17.Nd6#. So how to shift black's defenders to create an opening? White has an "extra" rook on a1 available for reload, so why not use the first to further weaken the light squares by eliminating the LSB? 16.Rxd7!! and now:
A) 16... N8xd7?? 17.Qf7+ Kd8 18.Nd6#
B) 16... N6xd7? 17.Qf7+ Kd8 18.Qxg7 Ng6 19.Nf7+ Kc7 20.Nxh8 Q|Nxh8 21.Qxe7 with 2 extra pawns and ongoing attack. C) 16... Qxd7 17.Rd1 Bd6 (Qc7?? 18.Qf7#) 18.Qf7+ Kd8 19.Rd1 Bd6 20.Rxd6! Qxd6 21.Qxb7 and the double threat of Nf7+ and Qxa8+ is decisive. D) 16... Kxd7 18.Nf7! Rg8 19.Nxe5+ Kc7 20.Bf4! Kd8 (Nh5 21.Nb5+ Kd8 [Kb8 Nxd7#] 22.Rd1+ Nd7 23.Qxg8+) 21.Rd1+ Ke8 22.Qf7# I think that's the gist of it. Kavalek was U.S. #2 in 1972. I played him in a simul in 1991 and lost, but I'm 1-1 versus GMs in simuls. Time for review... |
|
| Apr-04-15 | | CHESSTTCAMPS: Looks like a miss. I'll test against Crafty to see if 16.Rxd7 is viable. |
