|Apr-28-04|| ||InspiredByMorphy: 14.d5 15.exd6ep cxd6 16.h3 (if e4 now then Ng6 looks slightly better for black) Qh5 17. e4 d5 would have let to a more interesting and even game. |
|Apr-28-04|| ||Benjamin Lau: This is one of those cases where tactics are not very relevant and disagreements will center mainly around how to analyze the imbalances. I don't really think the game is even actually, white has the bishop pair and a lot of space after the pawn exchanges in your line. Coupled with better development, I think that white retains a good advantage in the game after your line. You're entitled to your own opinion of course. |
|Apr-28-04|| ||Benjamin Lau: In fact, white even sacrificed a pawn in the middlegame apparently to open up the board, so willingly exchanging pawns seems to play too much into the first player's hands. |
|Apr-28-04|| ||InspiredByMorphy: <Benjamin Lau> <white has the bishop pair and a lot of space after the pawn exchanges in your line> This is true, but what makes the bishops better than blacks knights in this position? Also the line I provided allows the activation of the blacks queen bishop, which in the game doesent get developed before white chases blacks queen down with the indirect effective 15. Be2. White does have more space, but blacks pawn structure is much better. Blacks biggest mistake was underdeveloping, but if such pawn structure could be held, pieces exchanged , and the endgame is attained, black would seem to have the advantage. But of course your entitled to your own opinion as well. |
|Apr-28-04|| ||Chessical: <InspiredbyMorphy> Before the endgame comes the middlegame. I must agree with <Benjamin Lau>, White's space and bishop pair seriously constrain Black e.g.|
<14...d5> 15.exd6 cxd6 16.Rb5! h6 17.h3 Qe6 18.Re1 a6 19.Rh5 f6 20.Nd4 Nxd4 21.exd4 Qf7 22.Bb4 Rd8 23.c4
and Black is under pressure.
This is the type of position that Rubinstein won from in so many of his early games.
|Apr-28-04|| ||InspiredByMorphy: <Chessical> Thank you for the second opinion concerning the bishop pairs. I look forward to checking out the variation you provided. |
|Apr-28-04|| ||Benjamin Lau: 16. Rb5! is a good resource chessical, nice find. |
|Apr-30-04|| ||InspiredByMorphy: <Chessical> <Benjamin Lau> In regards to 16.Rb5 It looks like a good idea, but blacks d pawn will move forward a square and block off its threats. 14. d5 15. exd6ep cxd6 16. Rb5 d5 17. h3 Qd7 18. Nd4 Qd6 19. Qh5 f5 |
|Apr-30-04|| ||Benjamin Lau: IBM: interesting line. 14...d5 seems good at a quick glance. I will go take a look at it tomorrow when I have time. Also at a quick glance, 20. g4!? in your line would be a fun try. 18. Ne5 (e.g. 18...Qd6 19. Qh5 maybe) also does not look bad. |
|Apr-30-04|| ||Benjamin Lau: <18. Ne5> (my idea) Qd6 19. Qh5!? seems possible in your line despite the apparent fork. (e.g. 19...g6 20. Qh6! (Qg5? and white is forked) Nxe5 21. f4 Qxa3 22. Bxe5 f6 23. Bb2 Qd6 24. g4! and black looks like he is in serious trouble, although this line is complicated and I may have missed something. Looks forced though.)|
What do you think about 20. g4!? Playing ...fxg4?! seems to invite a strong attack with lots of open files. Qxh7+ and Qxg7+ look bad for black.
|Apr-30-04|| ||Benjamin Lau: In my line, 18. Ne5 <Nxe5> 19. Bxe5 Ng6 (block Qxh7+) 20. Bb2 (this permits effective queen reorganization later i.e. Qa1 or Qc3) b6 21. Rb4 and white has a goood advantage although it is not as significant as with my previous 18. Ne5 (from your line again) Qd6 19. Qh5!? g6 20. Qh6! |
|Apr-30-04|| ||Benjamin Lau: Okay, in my frustration, I deleted my last three posts because it is clear that there is too much confusion and everything has to be sorted out again... |
A recap of what is going on:
IBM suggested an improvement to your line you gave earlier with Rb5!: 14... d5!? 15. exd6ep cxd6 16. Rb5! <d5!? new> 17. h3 Qd7 18. Nd4 Qd6 19. Qh5 f5.
So I gave some interesting ideas:
20. g4!? in his line seems wild but with complications favoring white
18. Ne5 in his line seems better
With regards to 18. Ne5, I said that:
18. Ne5 <Nxe5> 19. Bxe5 Ng6 (block Qxh7+) 20. Bb2 (this permits effective queen reorganization later i.e. Qa1 or Qc3) b6 21. Rb4 and white has a goood advantage
18. Ne5 Qd6 19. Qh5!? g6 20. Qh6! Nxe5 21. f4 Qxa3 22. Bxe5 f6 23. Bb2 Qd6 24. g4! seems very good for white.
|Apr-30-04|| ||Chessical: <Benjamin Lau> Working with IBM's variation: <15. exd6ep cxd6 16. Rb5! d5!? 17. h3 Qd7 18. Nd4 Qd6 19. Qh5 f5> - I like the idea of putting the R on the d file to prepare an assault on the d pawn. The position is very sharp:|
<20.Rd1> Qxa3 21.Nxc6 bxc6 22.Bb4 Qa6 23.Rxd5!
|Apr-30-04|| ||ughaibu: In this line why 17....Qd7 and not Qh5? Isn't the queen better off defending the kingside? |
|Apr-30-04|| ||Benjamin Lau: A good question ughaibu. I glanced over it before and it seemed that 17...Qh5 18. e4 was undesirable. |
|Apr-30-04|| ||Chessical: <Benjamin Lau> After <15. exd6ep cxd6 16. Rb5! d5!? 17. h3 Qd7 18. Nd4 Qd6 19. Qh5 f5> |
I have been looking at your suggestion <20.g4>. So far, I have only been able to explore at the aggressive:
<20...Qxa3> which I think is too dangerous for Black, e.g.: <21.Nxc6> Nxc6 22.Bb2 Qd6 23.gxf5 Ne5 24.f6! Nxd3 25.fxg7 Rf7 26.cxd3 Be6
I hope to look at 18. Ne5 <Nxe5> later. I am out of time for tonight, but look forward to further investigation of this intriguing position.
|Apr-30-04|| ||ughaibu: Benjamin: In response to 18.e4 what's the problem with 18....a6? |
|Apr-30-04|| ||Benjamin Lau: Maybe 18. e4 a6 19. Rb3 Rd8 20. exd5 Nxd5 21. Bd2 I suppose and white is slightly better but black has initiative. I sort of just followed IBM's line and I don't think that it's necessarily perfect of course. I used his line as a general sketch for the possibilities after ...d5!? Maybe your ...Qh5 is an improvement. |
|May-01-04|| ||Chessical: <Benjamin Lau><Ughaibu> Why not sac the exchange for a pawn and the continued initiative?|
14...d5 15.exd6 cxd6 16.Rb5 d5 17.h3 <Qh5 18.e4 a6> then:
<19.Rxd5> Nxd5 20.exd5 Nb8 21.Re1 Bd7 22.Re5
An alternative idea in <Ughaibu's> variation <17...Qh5>: 18.Nd4!? Qxd1 19.Rxd1 Rd8 20.Rc5 Be6 21.Rb1 Rab8 22.g4
|May-01-04|| ||Benjamin Lau: Nice line chessical. I didn't consider it mainly because it's not really in my style. If I ever give you a line with a speculative exchange sac, that means there is a typo. :) |
|May-02-04|| ||InspiredByMorphy: <Chessical> 20. ... Ne7 21. Bb4 Nxd5!
In my opinion by black giving the piece back, a slight advantage is held, due to the connected queenside pawns, as opposed to whites isolated queenside pawns. <18.Nd4!? Qxd1> Black doesent have to trade queens, and is better off not doing so. I must admit however that I do like whites position a little better as a result of 18.Nd4 , than what resulted from 18.e4 Here is an example of what black can respond to 18.Nd4 with - 18.Nd4 Qh4 19. Re1 Rd8 20. Qa1 Nxd4 21. Bxd4 Qg5 threatening 22. ... Bxh3 22. h4 (if ... Qxh4 then Bxg7) ... Qh6 (guarding the g pawn.) 23. e4 dxe4 24. Bxe4 a6 Black has the initiative, and if the small advantage of the queenside connected pawns can be retained until the endgame, then they may become a more substantial advantage. |
|May-02-04|| ||Benjamin Lau: IBM, following Chessical's exchange sack line with 14...d5 15.exd6 cxd6 16.Rb5 d5 17.h3 <Qh5 18.e4 a6> <19.Rxd5> Nxd5 20.exd5 Nb8 21.Re1 Bd7 22.Re5, is 20...Ne7 21. Bb4 Nxd5!? really that much better? For instance, now 22. Bxf8 Kxf8 23. Bxh7 and I think white is a pawn up with his heavy pieces occupying the open files. If that doesn't work, 23. Bc4 looks deadly too. |
|May-02-04|| ||InspiredByMorphy: <Benjamin Lau> I have found that whites position is stronger than I originally thought. I must admit, your line is the strongest one for white Ive seen yet on this page. 23.Bc4 is deadly, in fact it at least draws, if not wins since it wins a pawn and keeps the initiative. 23. Bc4 Be6 24. Re1 Nf6 25. Qd6+ Kg8 26. Re5 Qg6 27. Bxe6 fxe6 28. Qxe6+ leaves black can only hope to draw, and may very well lose. 23.Bxh7 isnt bad either, as your right it does win a pawn. I thought you had made an oversight at first as blacks queen is on h5, but it is I who made the oversight. After 23.Bxh7 Qxh7 24.Qxd5 threatening mate ... Be6 25.Qxb7 wins another pawn. |
|Feb-24-06|| ||An Englishman: Good Morning: Of course the line I looked at was 13.Ke2!?,0-0!?; 14.h3!?,Qxg2!?; 15.Rg1,Qxh3; 16.d6!?|
I'm starting to wonder what I'm putting in my coffee.
|Dec-31-09|| ||KingG: Why would a 2140 rated player play such a bad opening? After 8.Nd5! Black would have been in big trouble. For example 8.Nd5! Ba5 9.Rb5! Bxd2+ 10.Qxd2, and now Black has to play a move like 10...Kd8.|
