| Jul-19-19 | | Cheapo by the Dozen: The first two moves are pretty easy to find. But I didn't stick with the puzzle long enough to see that taking at f7 worked a lot better than taking at e6. My bad. :( |

 | | al wazir: <Cheapo by the Dozen: The first two moves are pretty easy to find.> Right. But I went astray with 20. Bxe6. After 20...fxe6 21. Qh4 h5, the attack peters out. If 22. Nxe6, then 22...Qe1! 23. Nf4 (23. Nxf8 Rxf8 24. Kh3, and black is up a ♖) 23...Nc2. Now white has nothing. |
|
| Jul-19-19 | | clement41: The tough defense to see is that after my initial 20 Qh4 h5 21 Qf4 with apparently deadly threats and a huge attacking position against weak king, the comp uncorks the cold blooded 21...Kg8 and says my attack just petered out |

I wasn't sure about 20 Nxf7+ either, and in fact went the same as you, thinking it looked as if it was winning. But again I didn't see the win after 21 Kg8.Engine analysis tels me that line doesn't win, but neither does 20 Nxf7+. B is not forced to play 21 .... Rg7 (... Rxf2! comes back drawn) or 22 Rxf7 (... Qd1!) comes back with a slight edge for B. Looks like 20 Nxf7+ is best but no significant advantage either way with best play from the set position. |
|
| Jul-19-19 | | 1stboard: What does stockfish say if black plays 18 Qa5 instead of the text move and declines taking the rook ? |
|
| Jul-19-19 | | malt: Went with 19.B:e6 at first ...fe6 20.Ng5 Rf5,
Then 19.Ng5 g6 20.N:f7+ R:f7
(20..Kg7 21.Ng5 B:c4 22.e6+ Rf6 23.Q:c4 Rc8 24.Ne4 ) 21.B:e6 Re7 22.Q:b7 Rae8 is as far as I got,
might have over looked 22.Bf7 |
|
| Jul-19-19 | | TheaN: Awesome combination. Yes <18.Nf3 Qxh1 19.Ng5 g6> is obvious, but White's down a rook and exchange so it must happen now. I erred with 20.Qh4?! h5 21.Nxf7 but this fizzles out quickly after the rather obvious 21....Rxf7 22.Bxe6 Rg7 -+ and White doesn't have access to the squares he needs whereas Black got h7 for free. With the queen on e4 on the pawn on h7 still blocking the king, the threats after <20.Nxf7+!> are very real. That said, countering with 21....Rxf2! puts up a lot of resistance so this is a very tough Friday. |
|
| Jul-19-19 | | saturn2: <1stboard: What does stockfish say if black plays 18 Qa5 instead of the text move and declines taking the rook> White wins a piece
18...Qa5 19. Bxe6 fxe6 20. Bxa1 |
|
Jul-19-19
 | | Alex Schindler: Saturn, not that 20. Bxa1 in that position is losing (whites already crushing), but in my analysis if you are white and your response to fxe6 isn't Ng5, then you are not the tactician who saw the value of 18 Nf3 in the first place. That knight on a1 isn't going anywhere; the king deserves the attention while Black's queen is still misplaced and white still has an initiative. The pawn on the fifth rank does a nice job cutting off the most logical defender, and from g5 your knight can remove the e6 pawn and proceed with the threat (as executed in the game) of continuing to use the knight to make tempo moves and allow the advance e6+ with discovered check. Whites piece coordination is marvelous, it would be a shame not to invite the knight to the party just to capture a comparatively worthless pony. |
|
| Jul-19-19 | | AlicesKnight: Quite well-known? - but I forgot the Bf7 bit (among other things) which is masterful, forcing open the long diagonal. |
|
| Jul-19-19 | | saturn2: <Alex Schindler: Saturn, not that 20. Bxa1 in that position is losing>
You are right but I only wanted to show it is still better for black to take the rook than playing Qa5. |

| Jul-19-19 | | patzer2: Today's (18. ?) puzzle, is taken from a game featured 8 years ago as a Sunday daily puzzle (20. ?). To solve this Friday puzzle, you had to find the two preparatory moves 18. Nf3 Qxh1 19. Ng5 g6 and then solve the Sunday May 22, 2011 puzzle with 20. Nxf7+! +- (+2.00 @ 35 ply, Stockfish 10). Moreover, the difficulty of the follow-up in this puzzle extends well beyond the first three moves 18. Nf3 Qxh1 19. Ng5 g6 20. Nxf7+! +-. After the clever defense 21...Rg7, White's only winning follow-up is the not so obvious 22. Bf7! +- (+5.58 @ 38 ply, Stockfish 10). An equally difficult follow-up occurs after the strongest defense 21...Rxf2! 22. Kxc2 Nc2, when White must find 23. Bf7! Qxe1+ 24.Kf3 Qd1+ 25.Kg3 Kg7 26.e6+ Kf8 and 27.Bc3! Qc1 28.Kf2! c5 +- (+2.73 @ 35 ply, Stockfish 10) to maintain a winning advantage. P.S.: For a Black improvement, instead of 16...Kh8? 17. dxe5 ± to +- (+1.77 @ 37 ply, Stockfish 10), I prefer 16...h6 = (0.00 @ 31 ply, Stockfish 10) as in Kasparov vs Adams, 2004. |

No white does not win a piece , he recovers a piece and material is approximately even , White Q + B + N vs Black Q + R + R .... So does Qa5 then hold ? |

|
| Jul-19-19 | | saturn2: <1stboard White Q + B + N vs Black Q + R + R >
You did not count the rook on h1. So your <18...Qa5> does not hold. |
|
| Jul-19-19 | | 1stboard: < saturn2>
You are correct , my typo , but material would still be approximately even .... White has Q + R + B + N
Black has Q + R + R
So again , does 18 .. Qa5 hold ..... ? |
|
| Jul-20-19 | | King.Arthur.Brazil: I found the combination, but failed with 20.♘xe6? when 20.♘xf7+ is clearly the best. Again I took the complicated way by chosing 24.exf7 ♔xf7. The resultanting position doesn't seem to punish the traveller black ♔. Then I though: I go wrong again (lgs). 
click for larger viewHowever, after 25.♕c4+ ♔e7 26.♕xc7+ ♔e6 27. ♕e5+ ♔d7 28.♕d5+ ♔c7 29.♗e5+ (now, if ♔c8? 30.♕e6+ ♔d8 31.♗d6 and # in 2) 29...♔b6 30.♕d6+ A- 30...♔b5 31.♕b4+ ♔c6 32.♕c4+ (if ...♔b6 33.♗c7#) 32... ♔d7 33.♕d5+ (♔c8 34.♕e6+ followed by the same mate with ♗d6; or ♔e8 34.♕e6+ ♔f8 35.♗d6+ ♔g7 36.♕e7+ (♔h8 37.♗e5+ or ♔g8 37.♗e5 and mate next) 36...♔h6 37.♗f4+ (g5 38.♕xg5#) ♔h5 38.♕g5#. B- 30...♔a5 31.♗c3+ ♔b5 (♔a4 32.♕b4#) 32.♕b4+ (♔a6 33.♕a5#) ♔c6 34.♕c4+ ♔b6 35.♗d4+ ♔a5 36.♕b4+ ♔a6 37.♕a4# For 34... ♔d6 35.♗b4+ ♔d7 36.♕d5+ (♔c7 37.♕d6+ ♔c8 38.♕e6+ followed by 39.♗d6 and mate next) 36... ♔e8 37.♕e6+ ♔e8 38.♗d6 and mate in 2. C- At line B, still after 35.♗b4+ ♔e5 36.f4+ ♔f6 37.♕d4+ (♔f5 38.♕e5#) ♔e6 38.♕d6+ ♔f7 39.♕d7+ (♔f6 40.♗c3#) ♔g8 40.♗c3 and mate next. Obviously, black can delay one move on that with ♕xh2+ or ♕xg2+ which is answered with ♔xh2 or ♔xg2, respectively.
Shortly, this line can win too, but requires the perfect order of moves to mate. It is not easy to find it during the game. |

 | | Sally Simpson: The Chess world took a while coming to terms with Kasparov losing to Deep Blue in May 1997. Readers Letters in the August 1997 CHESS say Deep Blue's opening book should have been removed or Garry, because he is human, should not have had to use a clock and could take an adjournment when ever he wanted. In an article in CHESS January 1998, page 23, titled; 'Computers Have Destroyed Chess!' Bogdan Lalic notes up this threads game.
Up to move 16 White had taken 3 minutes with the moves 17.dxe5! 19.Ng5! and 20.Nxf7!! home prep'd with a computer.
Bogdan ends with;
"With the appearance of computers in chess the sporting part of the game has mostly lost its meaning. Nowadays it is knowledge that decides, not creativity - as I have discovered to my cost..." citing these games; E Liss vs B Lalic, 1997 and B Lalic vs D Gormally, 1997 ending with 'computers have destroyed chess.' Whilst I detect a slight tongue in cheek, even back then I would have disagreed. Home prep is part of chess, the computer is a tool.
The impact computers have on chess I dislike is writers who use it as a crutch and write along what the computer is giving without any import from themselves.The computer should get a royalty fee. |
