Hi Dennis

There was a game today in the Greek team championship. There is an interesting Rook endgame arising at move 33.
It would be nice if you can explain some moves and ideas. At move 66 I think white had a chance with Ra6 but I dont know if this is enough for a draw

Tournament: Greek Team 2010

Round: 07

White: GM Nikolaidis, Ioannis

Black: GM Lupulescu, Constantin

Date: Sun Jul 11 2010

1. Nf3 c5 2. c4 Nf6 3. g3 d5 4. Bg2 Nc6 5. cxd5 Nxd5 6. d4 cxd4 7. Nxd4 Ndb4 8. Nxc6 Qxd1+ 9. Kxd1 Nxc6 10. Bxc6+ bxc6 11. Bd2 e5 12. Bc3 Bc5 13. Ke1 f6 14. Nd2 Be6 15. e3 Bd5 16. Rg1 g5 17.

Hi Dennis,

There is a famous endgame between Capablanca and Janowski that Pal Benko discussed in one of his CL columns some years ago. I can't remember the details, but my impression is that Capablanca's technique was seen as innovative, original, and not widely understood at the time it was played. Subsequently, it became part of every GMs endgame arsenal, and I believe Fischer even played a game once where he employed knowledge of the Capablanca ending to nail down the win. (In a somewhat ironic twist, I believe Benko showed that Janowski resigned prematurely in the original game.)

Are you familiar with this ending? If so, would you discuss its provenance and explain the technique so we amateurs might add it to our toolbox?

Thanks

Hi Dennis,
I just watched your analysis of the game Reshevsky-Vaganian, and I remembered another famous king march, this time a successful one. The game Karpov-A.Zaitsev (USSR 1970) is a real miracle! I mean, just look at that king standing on e4 like it's no big deal!
So can you possibly analyze it for us? The entire game is quite long, but I guess Zaitsev could have resigned much earlier. I just wonder why Karpov got himself into all those troubles, how he survived, and whether his idea of bringing the king to the center could be refuted. The most critical part of the game is about 25-30 moves long.
Thanks

There is an interesting positional pawn sacrifice in the advanced Caro Kann.
e4 c6 d4 d5 e5 Bf5 Nc3 e6 g4 Bg6 Nge2 Ne7 f4 h5 f5 exf g5
It is clear, that the bishop is out of play for a while, but the computer thinks this is OK for Black.
I would find it interesting to have some thoughts and explanations on the position.

Thanks

hey dennis,
How can you generate the appropriate plan for certain positions? For instance, how can you tell when to go on an all out attack, a buildup, or go for a positional battle?
Here's an example in which i had a real difficulity.
After: 1. e4 c6 2. d4 d5 3. exd5 cxd5 4. c4 Nf6 5. Nf3 g6 6. Nc3 Bg7 7. cxd5 Nxd5 8. Bc4 Be6 9. Qb3 Nc7 10. d5 Bc8 11. O-O O-O, white has a very visually pleasing game but i went for an all out attack and it failed here... normally people say to go for a knockout in positions where your opponent has terrible development, but does white have one here? what would you do in this position?
Thanks.

Hi, Dennis!!!

What is in your opinion the most promising line for white in the Gruenfeld? I looked at some lines in the Bg5 variation but they proved to be somewhat dull and black equalizes quite easily. Should I study the Russian system, the Exchange or the 8.Rb1 variation? I am standing at the chess "crossroad" now. Thanks!

Dennis, I've a question about a very rare line in the Siësta Variation of the Modern Steinitz Ruy Lopez, which is my defense with black.

Geller-Lutikov, Moscow 1961;
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. c3 f5 6. exf5 Bxf5 7. O-O Bd3 8. Re1
Be7 9. Qb3 b5 10. Qd5 Qd7 11. Qxd3 bxa4 12. Qc2 Nf6 13. Qxa4 O-O 14. d3 Nd4 15.
Qd1 Nxf3+ 16. Qxf3 Ng4 17. Qd5+ Kh8 18. f3 Nf6 19. Qb3 Qf5 20. Qc2 d5 21. Be3
Bd6 22. Nd2 Qh5 23. h3 Rae8 24. c4 c6 25. Qa4 e4 26. dxe4 Nxe4 27. cxd5 Nxd2
28. Bxd2 Qxd5 29. Bc3 h5 30. Rxe8 Rxe8 31. Rd1 Bc5+ 32. Kh1 Qg5 33. Qxc6 Re2
34. f4 Qg3 35. Qd5 Rf2 36. Qxh5+ Kg8 37. Rd8+ Bf8 38. Qd5+ Kh7 39. Qd3+ Qxd3
40. Rxd3 Rxf4 41. g3 1-0

The critical variation is with 9. Bc2 Bxc2 10. Qxc2 etcetera and the only other move I've ever seen here is 9. c4. Both are within my preparation, but there's a 3rd move I've never had to play against: 9. Qb3. While looking through Lutikov's games with the Modern Steinitz, I found this game where he plays against Geller and lost. The ideas in the game intrigued me.

I have two questions about move 13.
1) Doesn't black equalize with 13. Qxa4 e4! ? There are some pretty complicated lines there, it is the Siësta after all and I might've missed something.

2) In the game, white castled and black had a wonderful trick with 14. ... Nd4, making use of the knight capture with check on f3 and the queen opposition. In light of that and 13. ... e4 (should it hold). I thought white should maybe play 13. d3 here.
13. d3 0-0 14. Nbd2 This is my idea, white postpones Qxa4 by another move. I thought white could get a nice advantage out of this because if black moves either knight, the Nd4-Nxf3+ trick is off and black is hard pressed to find something that doesn't make him inactive. Whatever I do, white seems to get off well, though not winning by any means. At first I thought maybe a rook sac on f3, kind of analogous to the Sicilian would be nice, but I couldn't get any of it to really work. What do you think about 13. d3 0-0 14. Nbd2?


Many thanks in advance, I really enjoy your blog and your weekly sessions here.

Hi Dennis,

I have a question about the decline of the Benko gambit with 3. e3 (d4 Sf6 c4 c5 e3). The openings which arises are totally unfamiliar to me. I can play e6 and d5 which seems to be some Queens Gambit I dont know, or I can play g6 (more my style)
but this means I play more like a Grünfeld.
The question is, is there a drawback of the white setup, can I transpose to some favourable black setup against d4 cause of the early e3 pawn move?

Thanks

Hi Dennis,

My question is regarding the game given below. After my blunder on move 40, I had to try and take a decision on whether to give up a pawn or the exchange. I felt that my best practical chances was to give up the exchange but then try and keep the position closed so that his rook wouldn't be able to penetrate into my half of the board. Of course, 44. fxg5 wasn't the smartest execution of that strategy but overall, was the idea correct in principle? Or would I have been better off giving up the pawn on g3 and trying to hold?

Thanks!

Hi Dennis,

I have a serious problem. One so serious that I might actually be forced to quit Chess over it if I can't solve the issue. So I am coming to you for advice. My question pertains to momentary 'blackout blunder lapses' I seem to encounter routinely. The pattern I have identified but the cause and solution I can't haven't an inkling.

Basically, I play quite strongly (far above my rating) for almost the entire game until I have these momentary lapses once the position becomes EXTREMELY elementary (winning or drawing) for me. Then, I will make a colossal blunder by making a move that I didn't even analyze! An example (and I can give you countless more) Chess board: 8/2p5/1p1k4/6p1/1PP1KpP1/5P2/8/8 b - - Here I was black and it's my move. I have analyzed the obvious and forced only move .... c5 to draw but for some unexplainable reason I played Ke6????????????? where right after b5 I had to resign instantly. It is infuriating! To preempt the obvious inquiries, no I did not move too fast. No, it is not a lack of knowledge as the only move that occurred to me in that position was c5. I had not even ANALYZED Ke6. It is beyond me why it appeared on the board.

I've heard that Korchnoi favored playing the exchange french as an IQP position.

1. e4 e6 2. d4 d5 3. exd5 exd5 4. Bd3 c5

It seems like this approach should translate reasonably well to the queen's gambit declined. The following position seems no worse than anything that comes up in the QGD Tarrasch, and the computer claims it's almost equal.

1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. cxd5 exd5 5. Bg5 Be7 6. e3 O-O 7. Bd3 c5!? 8. dxc5 Nbd7

This is just one variation, but the basic idea is to meet Bd3 with c5. If white delays the capture, black pursues Re8 and Ne4 as in the Lasker. It goes without saying that black must be willing to accept the weak d pawn, but I'd take that over the mainline minority attack variations any day. Strangely, I've never seen these lines in any of the opening theory research that I've done. Is that because authors assume that black would have played the Tarrasch if he wanted an IQP, or am I overly optimistic about Black's chances here?

Hi Dennis

I've recently been looking at the 6.Bg5 variation against the Najdorf. I'm just wondering...what happens if black replies with 6...Qb6 immediately (rather than a move later in the Poisoned Pawn Var.) I only found two GM games with this position in my database, somehow white followed up with 7.f4 in both games and then black somehow didn't take on b2 with 7...Qxb2, which I don't understand at all...can you please explain this (assuming there wasn't some kind of mistake in the game score)? And how would you respond to this 6...Qb6 move as white?

Many thanks!

Hi Dennis,

I have recently found an interesting gambit against the Caro-Kann, and have tested it in several blitz games. It goes: 1.e4 c6 2.d4 d5 3.c4!?

Here's a sample line: 3...dxe4 4.Nc3 Nf6 5.Bg5 Bf5 6.f3 (6.Nge2 and Ng3 is another idea) exf3 7.Nxf3 e6 8.Bd3 Bxd3 9.Qxd3 followed by castling Queenside (or Kingside), with interesting attacking possibilities.

My blitz experience tells me that it's quite playable; I even once beat an IM in the variation above, but as I mentioned before, I've never ventured playing it with long time controls.

My questions are:
1) Does this line have a history?
2) Do you recommend it for anything other than blitz?

Thanks!

Hi Dennis,

I have a question about the line in the 3...g6 Ruy Lopez played in Shirov - Azmaiparashvili, Montecartene 2000, which is annotated by Nigel Davies on Chesspublishing. In this game, black seems to equalize fairly easily after 9...Bg4 10.Ne2, but Davies gives the move 10. 0-0-0, referring to the game Luther-Dautov, 1991, and concludes that it gives white "double edged play." In this game, however, white's main plan is f4, f5, and fxg6; with the help of Rybka, I have found the idea f4-f5 followed by e5, (as far as I can tell the order doesn't matter, as long as the two moves f5 and e5 are successive,) after which best for black two best tries are ...f6 and ...Re8. After ...f6 white can now play fxg6 and will meet ...Qxe5 (blacks best move) with gxh7 followed by Qh3. if black simply takes back on g6, white can play Qe4 or Rdg1 with an attack on the g pawn and an slight advantage. After ...Re8 white has f6 Rxd1 Rxd1 Qf8 Rd7 Nxf6 Rxc7 Ng4 Qf4 Nxe5 Ne4 Re6 Rxa7 and white seems to have the initiative
As far as I can tell, this idea has not been played at the master level, at least in the Mega Database 2009. Can you find improvements to blacks play, before or after the given line? Or is this good way for white to prove an advantage against this whole line, (which is pretty much forced until move 11?) Or maybe white's position in the line after ...Re8 isn't that great? Here is the line:

1. e4 e5 2. Nf3 Nc6 3. Bb5 g6 4. d4 exd4 5. Bg5 Be7 6. Bxe7 Qxe7 7. Bxc6 dxc6
8. Qxd4 Nf6 9. Nc3 Bg4 10. O-O-O Bxf3 11. gxf3 O-O 12. Qe3 {
e5 immediately might be better} Nh5 {This is not the only idea for black} 13.
f4 b6 (13... a5 {Is perhaps better?}) 14. e5 Rad8 15. f5 Rfe8 (15... gxf5
16. Rhg1+ Ng7 17. Rxd8 Rxd8 18. Qg3 Qf8 $14) (15... f6 16. fxg6 Qxe5 (16...
hxg6 17. Qe4) 17. gxh7+ Kxh7 18. Qh3 $14) 16. f6 (16. Rxd8 Qxd8 17. f4) 16...
Rxd1+ 17. Rxd1 Qf8 18. Rd7 Nxf6 19. Rxc7 Ng4 20. Qf4 Nxe5 21. Ne4 Re6 22. Rxa7
