 | | Sally Simpson: Hi Whiteshark,
"There's probably a story behind it..."
Indeed there is and it involves three games.
You have all heard of the Gothenburg Triangle
http://www.chessedinburgh.co.uk/cha... Every chess hack sometime or other falls back on it. I give it an extra twist after finding a Russian book on the event by by Igor Bondarevsky. Go there after reading this bit and see how I haggled to get it for 20p!! Anyway...where was I?....
You have all heard of the Gothenburg Triangle, now meet the Linares Double. In round one of the Linares 1955 Zonal, Tony Miles thrashed, (his words) Alberto David. A David vs Miles, 1995
Time passed and in the 7th Round this game (the thread game ) was played. Miles was leading by 1½ points and as tournament leader his game was being displayed on the sole demonstration board. Aleberto David arrived 10 minutes late for his game -v- Manuel Apicella (the game White Shark gives in the above post)
during which time this game (Illescas v Miles - the main thread game) was on move 10. Apicella happened to be sitting facing the only demo board and when Alberto David turned up
and played 1...Nc6 for the first time in his life (no doubt inspired by the Miles threashing) All Apicella had to do was follow the moves he had been looking at whilst waiting for his
opponent to arrive till they reached here...
click for larger view...when Apicella improved on the demonstration board game with 14.Nh4. ('It's Only Me' by Tony Miles, compiled by Nigel Lawson page 215) ---
What lessons have we learned today?
If you get 'thrashed' by an opening resist the temptation to try it yourself a few rounds later in such an important event. Always try to sit facing the demonstration board. |

Uh, I thought I would completely miss this puzzle, but I did recognize that c6 is pinned, so let's take a couple of times on d5. 18.exd5 Bxd3, but I played d6 right away instead of re-capturing on d3 first. |

 | | An Englishman: Good Evening: Another intuitive sacrifice--impossible that White could have seen all the way to the end of the game. Saw the first three moves and knew White had plenty of compensation. Went 6/6 this week after going 3/7 the week before. Just as inconsistent as in my playing days. The Ne7 chokes Black's entire position, so he needs to untangle somehow. Possible alternatives: 7...Nb8, 7...Bxf3; 8.Qxf3,Ne5, 9...Nxc6, and 11...Bxf3; 12.Qxf3,Ng6 or Nc8 intending 13...Nb6. |

| Mar-27-16 | | yadasampati: <An Englishman> Something is only "impossible" if it has been proved that it is not possible. I am pretty sure that is not the case here :-) I agree though, that it is hard to imagine, but that only tells me something about my own limitations. |

 | | al wazir: 30...Kg6 (30...Bf4 31. Qg4+ Ke4 32. Nc5/Nf6#) 31. Rg1+ Bg5 32. Qf6+ Kh5 33. Qxg5#. I went with the less enterprising (and less profitable) 18. Nxd5 Nxd5 19. Rxd5 b5 20. Bxb5 cxb5 21. Qxb5+ Qc6 22. Rxe5+ Be7 23. Qxc6+ Rxc6 24. Nf5. Those three connected queenside passed ♙s sure do look pretty, lined up there on the second rank, but it's a long way to promotion. |
|
| Mar-27-16 | | mel gibson: I saw this one in a few seconds however the computer recommends black play
23...O-O
score -1.79 depth 19.
I then played it at 5 seconds per move in auto play &
white still won but it was a long end game - 112 moves! |

| Mar-27-16 | | diagonalley: hmmmm... roll on monday, when sanity can return |
|
| Mar-27-16 | | Once: Heck, but that's a powerful attack. I didn't come close. |
|
| Mar-27-16 | | agb2002: White has a bishop and a knight for the bishop pair. Black threatens 18... dxc4 and 18... b5.
The first idea that comes to mind is 18.Nxd5 Nxd5 19.Nxg6 hxg6 20.Rxd5 A) 20... b5 21.Bxb5 cxb5
A.1) 22.Qxc7 Rxc7 23.Rxe5+ Be7 24.Rxb5 and White has four pawns for the bishop, three of them linked and passed. A.2) 22.Qxb5+ Qc6 23.Rxe5+ Be7 24.Qxc6 looks similar to A.1. B) 20... f6 21.Rhd1 b5 (due to 22.Bxc6+ Qxc6 23.Rd8+) 22.Bxb5 cxb5 23.Qxb5+ Kf7 (23... Ke7 24.Rd7+ and mate in two at most) 24.Rd7+ wins decisive material. I don't have time for more today. |

| Mar-27-16 | | morfishine: Clearly, its a capture on <d5>, but which capture? I looked at all three and they all seem playable, but that's not saying much: I think the Grob is playable for crying out loud |

 | | Fusilli: Lazy Sunday... I didn't even try. Looked at it and went ahead and started to press the forward key, enjoying this masterpiece of attack. What a beauty. |
|
| Mar-27-16 | | morfishine: <Fusilli> Thats not like you, but I understand, I'm just lying around playing Chess960 over at ChessCube...its raining outside but it should clear later so we'll grill up some steaks, have a few beers, tell a few jokes |
|
| Mar-27-16 | | recluse52: Qa6 maybe |

| Mar-27-16 | | leRevenant: <diagonalley: Fusilli: > ditto, ditto, but it's already way into Monday where I am. |
|
| Mar-27-16 | | patzer2: Strange week of puzzle solving for me. Missed Monday, but got at least the first couple of moves or more of the next five Tuesday through Saturday puzzles. However I couldn't make it six in a row, as I bombed on today's Sunday puzzle with a best guess of 18. Nxd5 which levels out after 18...Nxd5 =, as play might continue 19. Qxd5 Ke7 20. Nxg6+ hxg6 21. Bxc6 Qxc6 22. Qxe5+ Qe6 23. Qg5+ f6 24. Qxg6 Qc4 25. Rc3 Rxh3 26. Rhxh3 Qf1+ 27. Kd2 Qxf2+ 28. Kd1 Rd8+ 29. Rhd3 Qf1+ 30. Kd2 Qf2+ 31. Kd1 Qf1+ 32. Kd2 Qf2+ 33. Kd1 = (0.00 @ 24 depth, Deep Fritz 15). I considered the game winner and Sunday puzzle solution 18. exd5!! Bxd3 19. Qxd3  (+1.95 @ 25 depth, Komodo 9.02). However, even though I visualized the position, I didn't realize it was a win for White after 19...Ng6 (diagram below)

26. exd6 Rxd3 27. dxe7+ Ke8 28. cxd3 (+5.62 @ 24 depth, deep Fritz 15). P.S.: Difficult to find a Black improvement in this game, as White gains a strong advantage in the opening due to the fact that Black fails to effectively challenge White's active development and strong center. Instead of 11...Nd7 12. g4!  (+1.42 @ 24 depth, Komodo 9.2), perhaps the computer suggestion 11...Bxf3 12. Qxf3 Ng6  (+0.41 @ 30 depth, Stockfish 6) would give Black better play than the game continuation. Early in the opening 4...g6, as in the Blitz game Kasparov vs Short, 2015, might be worth a shot. |
