Message: After 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Qe2 the choices are 4.Nf3 or 4.d4, blocking the eventual Q-check on the e-file by Be2: 4.Nf3 Qxe4 5.Be2 or 4.d4 d3 5.Nf3 Qxe4 6.Be2 You will find that White's record on GK 1900+ is very good for 4.d4, and pretty mediocre for 4.Nf3. To what extent this is a real measure of their respective worth, I leave you to judge (I have just 1 master game that features 4.Nf3, and that was a White win).

A thrilling accomplishment, no doubt. But chess fans have grown numb to the exploits of adolescent wonders. The inimitable Bobby Fischer stunned the world by becoming a grandmaster in 1958 at age 15 years, 6 months, a record that lasted until 1991. In the last two decades, though, 23 chess players have surpassed Fischer's mark. Sergey Karjakin, the Ukraine star who now plays for Russia, holds the current record at 12 years, 7 months. The World Chess Federation's March rating list includes ... Posted by bucklehead | www6conf.org 1/28/2007 13:46:40 Play online chess Some theory...Message: Anyway, Ion is quite correct to suggest that 3...Qe7 is fairly well met with 4 d4. After a fairly natural progression such as 4. d4 d6 5. Nf3 Nxe4 6. Be2, white stands well and should complete his development without trouble; black, on the other hand, is hampered by the position of his own queen, and must waste a move getting it off the e-file in order to complete development. If this is not done prior to white achieving 0-0 and Re1, the queen's position on e7 could even become a liability. The other line you give, 1. e4 e5 2. Nf3 Nf6 3. d4 exd4 4. e5 Qe7, is a teensy bit trickier because black actually threatens to win a pawn. However, after white executes a basic 5. Be2 (undercutting black's entire plan) black is left needing to retreat the Nf6. On 5...Nd5, ...Ne4, or ...Ng4, white can seek a quick draw with 6. Qxd4 Qb4+ and a queenswap. But since the black pawn on d4 is hard to defend, there's no sense in chomping it immediately--white can use the time to develop and let black start to feel cramped by that Qe7. ——— World No1 Magnus Carlsen parts company with mentor Garry Kasparov — The most significant chess news this month is a negative item. A carefully scripted and bland press release announced that the world No1, Magnus Carlsen, would make his own chess career decisions for 2010 and that he and the all-time No1, Garry Kasparov, would cease their regular training sessions launched early last year. The statement claimed that, with 19-year‑old Carlsen established at the world top, his cooperation with Kasparov had achieved its objectives ahead of schedule and that the Norwegian no longer needed constant guidance. Carlsen won his last two chess tournaments in London and Corus Wijk but displayed weaknesses and is as yet far from ...

Why? — The World Chess Federation, the governing body of the game of chess, released new “antidoping rules” for chess players on Tuesday. The rules replace, or update, previous guidelines. Drug testing was begun several years ago to bring the federation, and chess, in line with the rules and requirements of the International Olympic Committee and other international sporting organizations. Part of the reason was to get chess included in the Olympics — an idea that seemed far-fetched, at best. Chess players have complained about drug testing and pointed out that, aside from caffeine — which many competitors consider essential — there are no drugs that can ... Posted by bucklehead | www6conf.org 1/29/2007 14:24:23 Play online chess Completely playable...maybeMessage: So let's spin this out a little: 1. e4 e5 2. Nf3 Nf6 3. d4 exd4 4. e5 Qe7 5. Bd3 d5 6. 0-0 Ne4 7. Nxd4 [an immediate 7. Re1 c5 and white misses his chance at capturing d4] ...Qxe5 Black has more or less "covered up" and is free to develop. An immediate 8. Re1, pressing the queen-pinning theme, is possible and could lead to a trap: 8...Qxd4?? 9. Bb5+! and black is in serious trouble. 8...Bc5 is simpler and better. And let's not forget that, in these lines anyway, black is up a pawn. As I write this I'm double-checking it with a computer, and I think ...d5 is the killer in the Bd3 line. White needs to defend e5 *and* find a way to grab d4 in order to maintain material equality, and I'm not sure this is possible. Recall that in the main line of the Petrov's Modern Variation (1. e4 e5 2. Nf3 Nf6 3. d4 exd4 4. e5 Ne4), white usually proceeds immediately with 5. Qxd4, levelling things out; the advanced e5-pawn is then very often traded against black's d-pawn. Once robbed of this opportunity by ...d5, white is tied down to the defense of this advanced outpost, a tricky business since d4 is already lost. The more I look at it, the more I think that Bd3 is inferior. The longer white can maintain his outpost at e5, the longer black will remain cramped. Blocking the white queen's access to d4 (and shifting the recapturing burden to the Nf3) undermines this outpost. ——— The f-pawn, part 4: what to do when it goes wrong? — Black has taken White's f-pawn, leaving White exposed. Is there a way to deal with it? RB Over the last few chess columns we have been looking at the f-pawn as battering ram – an early, bullish advance to break open the enemy king's position with sheer aggression. But here the f-pawn has been exchanged very early – on the seventh move! There is no ram with which to batter, and the rook on f1, the usual beneficiary of any successful f-pawn push, is staring down at a solid phalanx of enemy pawns. Manoeuvring rather than force seems to be called for. But manoeuvre what where? Looking at White's own setup, there's an obvious target for ... Posted by sf115 | www6conf.org 1/30/2007 12:17:20 Play online chess Message: ——— Tobey Maguire Playing Bobby Fischer? — Maguire might have just lost a franchise character in Spider-man, but it looks like he might be playing famous chess icon, Bobby Fischer, in the film "Pawn Sacrifice". Pawn Sacrifice follows Bobby Fischer who has to face the Russian chess champion, Boris Spassky, in 1972, in a game filled with Cold War overtones. Basically think Rocky IV just slightly geekier (only slightly). The film is being written by Steven Knight, who is also working on Matt Damon’s recently announced Robert F. Kennedy biopic, has apparently had the script written for Pawn Sacrifice for some time. No doubt the film will focus more on the earlier days of Fisher before he became a recluse, and started ...

O-O Ne4 not convinced Posted by bucklehead | www6conf.org 1/30/2007 14:31:31 Play online chess Chess solves all problemsMessage: From a purely strategic perspective: white's problem here is that he's still a pawn down from move 3; and while black's doubled d-pawns are vulnerable, he has several immediate (and developmental) protection mechanisms: ...c5, ...Nc6, and ...Bg4 spring to mind. Even if white considers one of these d-pawns to be "in his pocket," so to speak, the d4-pawn will exert some cramping influence until it's removed. Meanwhile, white's outpost on e5 (cramping aganst black, to be fair) is on shaky ground--it's both difficult and unwise to protect it economically with the f-pawn, and moving ahead with Bf4 seems like a clogging of the developmental arteries. Re1 is of course attractive, but has no effect while black's Ne4 stands in the way. So there are challenges. For another perspective, let's strip away the pieces (and black's d4 pawn) and look at the pawn skeleton: I think I'd prefer black's side here, even if you assume a prior ...0-0 and put black's king on g7--because black is a move closer to bringing his K to the battleground around e5, and white is far away from bringing his K to challenge black's queenside majority. Of course, this is completely hypothetical, but I guess that's what it's all about.

(I'd also argue that 5. Be2 is the superior move, but we can leave that aside.) What say you all, learned commentators of GK? Posted by sf115 | www6conf.org 2/04/2007 03:53:29 Play online chess Message: Posted by calmrolfe | www6conf.org 2/05/2007 15:04:04 Play online chess Message: Other tries include 4. d4 Qxe4+ 5.Be2 d5 6.0-0 Bg4 7.Bb5 with good position for White. I am aware of 86 master games that have started 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Qe7 and these have resulted in 44 wins for White, 26 draws and 16 wins for Black. Not a very promising opening for Black given those sort of results. Ratings wise, the leading Black exponent of these moves would seem to be Vladimir Afromeev 2547 who unleashed this opening twice in the Tula Stek Cup in 2004 and the shock value brought him two wins ! Since then he seems to have put the opening into his back pocket, perhaps for a future surprise !! Playing Blitz as White I have encountered 3.....Qe7 several times and I can't remember it ever working against me, although in fairness I haven't met it OTB over a longer time frame. For my money, 3.....d6 is the ONLY move I would make in the Petroff, and the Petroff is my most solid defence of preference when drawn against strong players.

Or Black might try 7...Bf5 8.Nd5!? Qd6 9.c4, with 10.Bf4 coming up. All round, it looks pretty good for White, though I haven't found anything immediately decisive.

And I don't know about the rest of you; but when it comes to my opening preparation, this is about as much time as I like to spend on a rare and weaker line. |
