 | | chessgames.com: <I really do hate to report things like this, but the puzzle was also used last Friday.> Ugh!!! I'm not sure what to do. I don't believe this problem has ever come up, at least beyond 1am. <sonia91> Sorry about that, we'll get that game in shortly. |

| | chessgames.com: We decided to replace the rerun with an older rerun. So there are two puzzles of the day for April 29, 2016. The replacement Piskov vs M Krasenkow, 1989 is a beauty from 2004. |

| | Phony Benoni: This is a strange one! The link from the home page to the GOTD, Tal vs Grave, 1965, instead goes to Caruana vs Anand, 2016 |

| | chessgames.com: Ugh, that's happened before, I think it's just a copy-and-paste error. I fixed it late last night. |

 | | Domdaniel: <CG> If I go to the statistics page, and check out the list of members with the greatest number of posts - I think I'm #9 - and if I then click on #15 on this list, I'm told there is no such member... Can this be explained? Or are you turning people into non-persons? |
|
Apr-30-16
| | Domdaniel: <CG> To be precise: the "statistics" category is "which users have kibitzed the most" ... and the message on clicking on #15 is "no such user on record". |

| May-02-16 | | sonia91: <cg.com> Thanks for adding that game. Yesterday the <Russian Team Championship> started. Svidler, Grischuk and some other 2700+ players (more than the Hasselbacken Open) play, also Kamsky plays. In the women's division Lagno, Goryachkina, Ushenina among others play. |

 | | MissScarlett: Games of the 2016 Paul Keres Memorial should be rapid, not classical. |

luftforlife, we're happy to have you on board! |

| May-04-16 | | Jabot: Strangely the games I have been viewing in the Panov-Botvinnik attack are described as being nimzo indians rather than caro-kanns. For instace
Kamsky vs Karpov, 1996 |

 | | SwitchingQuylthulg: <Jabot> That's a bit strange, but it's not a bug; the position after Black's 6th move can be reached via either the Caro-Kann or the Nimzo-Indian, and the Chessgames opening classification table (which is basically <Eric Schiller>'s Caxton opening list) gives the Nimzo-Indian priority. Basically, this means the Kamsky-Karpov game (together with other Caro-Kann games in the same line) is viewed as a transposition to the Nimzo-Indian. The case could certainly be made that this is the wrong way round, since the key position is more commonly reached through the Caro-Kann; Eric Schiller's opening nomenclature is often quite idiosyncratic. |

| | chessgames.com: I checked that idiosyncratic data file and the critical record is this one 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 c5 5.Nf3 cxd4 6.exd4 d5 which is exactly the same thing as
1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 e6 6.Nf3 Bb4 which is

| | SwitchingQuylthulg: <chessgames.com: I have the ability to reassign it, but it's not clear to me which designation is correct. Over the years I've come to learn that there isn't always a definitive answer to that question.> It can be called either a Caro-Kann or a Nimzo-Indian; neither designation is definitively wrong. There's a strong case for calling it a Caro-Kann, though; namely: 1) of the 1170 games we have with that position, 1026 (87.7%) have White play e2-e4 (identifying the opening as a Caro-Kann type) and only 144 (12.3%) have White play e2-e3 (Nimzo-Indian); 2) while Schiller calls it a Nimzo-Indian, he also calls it a Panov Attack, which means a Caro-Kann with 4.c4. |

 | | perfidious: Almost no-one uses the Nimzo move order featuring 5....cxd4 6.exd4 d5 to reach the position from the above diagram, whereas the Caro-Kann method has become very common since the 1990s. Another quirk of the system is how 1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.d5 exd5 5. exd5 d6 6.Nc3 invariably winds up under E10, whereas 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.exd5 d6 6.Nf3 is rightly classed as a Modern Benoni. Don't get me started on all the transpositions to various forms of the Dutch following 1.Nf3 f5 which are classified under A04.... |
|
| May-04-16 | | luftforlife: The foregoing colloquy begs the question: if ECO Codes A60-A79 are the Modern Benoni Defenses, and A43-A44 are the Old Benoni Defenses, and A56 is the Czech Benoni, then is the E10 Blumenfeld Counter Gambit the one and only "<Phony Benoni>"? |

| | chessgames.com: <Almost no-one uses the Nimzo move order...> That's what it really comes down to. The moves themselves aren't enough: opening designation involves determining what's in style and what's passé. |
|
| May-05-16 | | zanzibar: I think classification simply by position will always be flawed. There should be some hysteresis from the opening moves feeding into the classification, allowing the transpositions to be sorted out. Of course, that's my personal opinion. |
|
| May-05-16 | | sonia91: Two top 10 players are currently playing a 4-game match in Shanghai, China: after Ding Liren - Gelfand (2015), Ding plays this time Wesley So. |
|
| May-06-16 | | zanzibar: A nice example, from the literature, of the nuances missed by ECO codes: <A curiously varied opening, changing from " Bird's Opening" into a "From Gambit," a "King's Gambit Declined," and here at last into a "Falkbeer," which, it will be remembered, was played by Blackburne against Gunsberg in the Bradford match.> |
