| Aug-10-05 | | prinsallan: <chessgames.com>The black name is wrong... It should be "Krabbé". Heres the text I found online at:
http://www.xs4all.nl/~timkr/chess2/...
Seeing nothing against Qxf7, Black resigned. Later, Kurt Richter showed in the Deutsche Schachzeitung that he could have drawn with 32...Rc2 33.Rf1 Rc1 etc. But over 30 years later, in his book 'Der letzte Fehler', Klaus Trautmann showed Black could even have even won: 32...Rc2 33.Rf1 and now Qd2! and 34.Rg2 Qxg2+ 35.Qxg2 Rxg2+ 36.Kxg2 Bxa4 and wins, or 34.Rh3 Bxa4 35.Kh1 Be8 36.Rg1 Re7 37.Qf6 Qg2+ 38.Rxg2 Rc1+ 39.Rg1 Rxg1+ 40.Kxg1 gxf6 'White will hardly find a way out'. |

| May-16-11 | | rilkefan: Where did white go wrong? Or is there an improvement on 33.Rf1? |
|
| May-16-11 | | newzild: <prinsallan> Interesting. In the second variation (with 33. Rh3) White's moves are not forced. However, I can't see anything better for White than the moves suggested by Krautmann. |

 | | Gilmoy: And if Black doesn't follow <al wazir>'s line, 32..Re7 33.Qf6 is the same deflection the other way, overworking the R at f8/g7. |
|
| May-16-11 | | vodkaboris: The game title pun works in more than one way. Tim Krabbe is also a cycling writer, and one of his quotes (from 'The Rider') goes: 'Road racing imitates life, the way it would be without the corruptive influence of civilisation. When you see an enemy lying on the ground, what’s your first reaction? To help him to his feet. In road racing, you kick him to death.’ As in road racing, so on the chessboard.... |
|
| May-16-11 | | erniecohen: How about 32...  c2 33. f1  d2 34. h5? e.g. 34...  xa4 35.  h1 e8 36. d1 f2 37. xg7 xh2+ 38. xh2 xh2+ 39. xh2 xg7 and white should be able to eek out a draw, right? |

 | | sevenseaman: 32. Bf5 bisects Black' power on 'f' file into half. Black is rendered a walking-wounded and his R on f7 is lost. A similar dilemma occurs on the seventh rank for Black in this set up.

| | sevenseaman: < al wazir: al wazir: 32...Qh6 33. Qxh6 (33. Qxf7?? Qxh2#) gxh6 34. Rg8#.> Brilliant! I could have ignored the Black Q on h6 and learnt a lesson of my life. |

 | | kevin86: A funny game: much of the early movement is by pawns and knights... The coup de grace is:32...e7 33 f6!! gxf6 (otherwise the queen mates) 34 g8# |
|

| | kevin86: My bad-black's best play is after 32{...Rc2!! (threatening mate),black can draw or even win...,instead,he resigns. |
|
| May-16-11 | | Yerbamate: what about black response: Be8. I don't have any program to test the continuations...but seems good defend?
Maybe not, i'm just a noob. |
|
| May-16-11 | | sneaky pete: If 32... Re7 33.Qf6? Qxg3+ black has at least equal chances, but 33.Bxd7 .. should win. If 32... Be8 33.Qe6 Rf8 34.Qe7 .. looks good enough. |
|
| May-16-11 | | mooseheadchris: <kevin86> I think white's best response to 32... Rc2 is simply 33. Rf1 then 33... Qd2 34. Rg2 QxR 35. QxQ RxQ 36. KxR BxB 37. RxB RxR 38. exf5 Kxf7 gives white two passed pawns and probably 1-0. Should black choose not to trade down, white's game is winning. |

then 33... Qd2 34. Rg2 QxR 35. QxQ RxQ 36. KxR BxB 37. RxB RxR 38. exf5 Kxf7 gives white two passed pawns and probably 1-0. Should black choose not to trade down, white's game is winning.> Instead of 36...x, black can just play 36...xa4, with a winning advantage. See my post above for a better line for white that should draw, but that's the best he can hope for here. |

| May-16-11 | | eternaloptimist: This is perhaps the most ruthless pun that I've seen 4 game of the day. It's definitely much more ruthless than my pun which was used 4 yesterday's game of the day. Krabbe has 1 of the most interesting websites that I have ever seen.: http://www.xs4all.nl/~timkr/chess/c... |

| May-16-11 | | ajile: This is called "interference" correct? |
|
| May-16-11 | | Oceanlake: 17 g5? |
|
| May-16-11 | | eternaloptimist: <ajile> Yes it is. I had completely forgotten about this tactic. Here is a link.: http://en.wikipedia.org/wiki/Interf...(chess)
32.f5!! is an excellent & difficult move to find. IM Langeweg did a great job of being alert in this game. |
|
| May-16-11 | | WhiteRook48: 32 Bf5!! is an extremely awesome move, that interferes with all of Black's defenses |

| | sevenseaman: <ajile> <This is called "interference" correct?> Interference yes, but the technical term is 'Novotony' (or Nowotony). White intervenes a piece that can be captured by two different enemy pieces but using either Black ends up furthering White's original objective. This is what happens here;
click for larger vieww mates in 4. White inserts the R at e7 and Black cannot take it with his R ( allows 2. QxR#) or with his B (allows 2. Qxh7#). Black can refuse, say 1...Rf7 2. Rxe8+ leading to quick mate again. I had posted this position from an unknown game yesterday to illustrate 'Novotony' but no one noticed it. |
|
| May-16-11 | | ajile: Cool example. |

| | Gilmoy: <sevenseaman>'s puzzle is an example of <Novotný interference>, after the Czech lawyer Antonín Novotný http://en.wikipedia.org/wiki/Anton%.... Novotný means you sac a piece outright on a square where two enemy line-movers criss-cross. Whichever one captures, cuts the other one's line. <ajile> is also correct: this game's finale <32.Bf5> is a "normal" interference, without anybody's name. It's not a piece sac, because White's B is simply protected. (So it's a pawn sac, but that's a lot easier to calculate.) This theme must have been known since antiquity, and we didn't need any modern composer to teach it to us. Much rarer is the <Plachutta> http://en.wikipedia.org/wiki/Plachu..., in which both line-movers move the same way. Plachutta requires 1 sac to force either defender to capture on a critical intersection, where it becomes overworked, and a 2nd sac to deflect it. That means a position where the defender has RR, QR, or QB, and the attacker has two sacs <and> a mate fork: Tarrasch vs Allies, 1914. Some newer exemplars are rumored to exist; anybody have a collection? |
