Answering questions

  1. PART I:

    This is my “stream of consciousness” review of your first game. I’m not criticizing your play; just trying to figure out what was going on in your mind as you played. My interest is in trying to see (if possible) potential deficits in knowledge/skill that we may share. I have never played this opening with White, generally preferring a more traditional Queen’s Gambit approach with the potential to attack on the queenside with a minority attack rather than a piece/pawn attack on the kingside.

    I have no idea how far into the opening you had studied/memorized this variation, but it seems you had a better feel for it than your opponent. After move 3 I was out of book



  2. In this first game, Black’s plan (7...Nh5; 8...Nxf4) to exchange off the WBf4, doubling White’s f-pawns (and also opening the e-file for White and creating a pawn break on f5) seems dubious to me because White has completed development and is prepared to begin active operations. Back still has to get his king out of the center and his queenside piece development has far lagged behind. Playing 9...c5 seems foolhardy under the circumstances. You rightly saw the possibility of cranking open the e-file with 10.f5. After 10...Nf6 11. Bb5+ you saw the tactical possibility of gaining a pawn with attacking chances on the kingside. After 11...Bd2 12. fxe6 fxe6 it appears that you immediately went for the pawn gain. I assume you mean 11. ... Bd7. No pawn gain was on my mind. I wanted to pry open the e-file and to prevent him from castling

    I’m curious: I know you like attacking play and I know you can SEE the outline of the potential tactics in this position. Why did you reject 13. Ng5? It appears to give you the extra pawn AND to also get your knight into e6 (the ‘octopus knight”!) with tempo. You would have had an even stronger initiative as a result. Does GM Smirnov’s “To take is a mistake!” aphorism apply? I wanted to put pressure on Be7 as soon as possible. I have two rooks and a queen ready for that. It was hard to judge the details. Maybe saccing the exchange was in the air.

    This s one of the areas I have been working on (and still need to work on) – rather than striving to gain material at the first opportunity, perhaps deferring the material gain (or foregoing it altogether) in favor of increased piece activity and complications (i.e., tactical threats that put the pieces in more active positions).

    Black appears to be setting up for a potential raid on h2 after 16...Qc7. The WNf3 might be captured by the BRf8, with a strong attack of queen and knight against your king. Why capture on c5? It brings Black’s queen to a stronger position in the center, and does not improve your piece positions. It does. It makes d3 a save place for my queen and gives d4 to my knight. Why not try to get the White queen off the 1st rank (perhaps d3) and bring the a8 rook into the action on either the d-file or e-file, putting immediate pressure on the IQP? As GM Aagaard says, bring ALL of the pieces to the party when you are attacking!

    Why did you immediately play 17. Nd4? It threatens a knight fork and the defender of Be7 (the black queen) Were you already looking at 18.Ne6, to be followed with an exchange of queens by playing 19.Qd4? Did you consider a plan of getting the queen off the 1st rank (17.Qd3) followed by developing the a8-rook as needed to increase pressure on d5 or e7? It appears that you were applying “one piece at a time” thinking, rather than trying to coordinate ALL of your pieces toward potential targets (a frequent failing of mine). I missed the deadly move 18. a3. Pawn b2 is poisoned, winning the queen, Qc5 allows to win the exchange and other queen moves lose the bishop.

    Black’s 18...Rf7 appears to be a mistake. With 19.Ng5, White gains a strong attack because his pieces are very well coordinated. The BRf7 and BBe7 are targets, and the BRa8 is doing nothing. I started having “fantasies” of things like grabbing the BBe7 (if the Black rook reverts to f8 and/or the Black queen takes on b2) and also a potential classic smothered mate pattern (WN takes on d5, BN takes back, WQ takes with check, BK moves to h8, WN goes to f7 with check. Black would probably give up the exchange and take the knight, rather than permit the smothered mate with BK to g8, WN to h6++, BK to h8, WQ to g8+, BRxg8, WN to f7 mate). Somewhere in there I would have to figure out what to do about the a1-rook (under attack if Black captures on b2 and the WQ is on f7), but it certainly looks more promising than Black’s possibilities.

  3. PART II:

    I did not understand your decision to trade queens and go into an endgame, even though you are a pawn ahead at the moment. Neither did I. So far I was totally winning. Yet one silly move shouldn't be losing. Here a hole in my bucket shows. If I can't come up with a plan, I start to use time and to make mistakes. The rest is irrelevant, since I must first absorb a few standard endgame plans. You lost the initiative and Black ruined your pawn structure in short order, enabling him to regain his material with interest. Did you assume that getting rid of the queens made it easier to win the IQP? The classical method for capturing the IQP requires the major pieces (and that c3 pawn assassin). Black is able to force doubled c-pawns (because of the combined threat against your rook on e3 and the f2-pawn, which is more than adequate compensation for the pawn minus and the IQP (which can no longer be won using the classical plan).

    Assessing the position after 24...Rc8, I think Black has the advantage of better pawn structure. Both sides have three pawn islands but Black’s IQP is easily protected with the BN and the two connected queenside pawns are better structurally than the isolated a-pawn and the double c-pawns. White’s 3:2 majority on the kingside will not be a factor until very late in a pawn endgame, if at all.

    After 29...Nxc3, the primary consideration is that a knight and pawn endgame should be played essentially as if it is a pawn ending (Botvinnik’s “rule”). It is crucial is to get the king to the center of the board ASAP. I’m doubtful that it would hold the draw, but at least it’s a chance. Trying to advance the 3:2 kingside majority to create a passed pawn is too slow in light of the advanced b-pawn; it merely weakens the pawns for when the Black king comes calling. Perhaps a better way would be to try to get the White king in front of the b-pawn, trying to keep the Black king tied to its defense, freeing up the night to shepherd the kingside pawns forward. However, if the knights can be forced off, then the “fox in the chicken house” strategy works: White is forced to spend time going after the b-pawn, while the Black king is free to raid the kingside pawns.

    I look forward to your critique of my thoughts! Thank you!!

  4. That I missed the tactical win? No worries, I'm working on that. That my attack was a bit suboptimal? No worries, I'm studying the art of attack.

  5. But the lack of an endgame strategy is a serious hole in my bucket. And it is placed low, every player above 1850 escapes trough it. So I must plug this before anything else. I don't like it, but I have to.

  6. In general, I use the following criterium: when I start to use time and cannot come up with a plan: there is a hole in my bucket, and if it occurs frequently I must plug it before anything else. But it takes time and energy to shift plans often.

    1. I'm a bit more ambitious than that. Or cocky, if you like. I don't think that My System from Nimzowitsch nor The art of attack from Vukovic are final works. I don't think the authors looked at them that way. It are beginnings of a new area of chess thinking. And I like to elaborate on that. Or at least, to work out a version that I can call my own. Because I think that is fun. It might not pay off immediately, but it will do so in the long run.

  3. I'll repeat a little of what I learned from GM Jacob Aagaard's Grandmaster Preparation: Thinking Inside The Box. (I previously posted a long series of comments based on that book on June 20, 2021; I won't bore you with a total repetition.)

    ."At one point, by means of an abstract association with another subject, I realized that often the problem is not that we are unable to come up with the right answers; but rather that WE FAIL TO UNDERSTAND WHAT QUESTIONS WE SHOULD BE ASKING."

    "One day I spent an afternoon writing a long list of recurring questions; I then pruned it. I wanted a very short list: one I could remember."

    "1. Where are the weaknesses?"
    "2. What is my opponent's idea?"
    "3. Which is the worst placed piece?"

    "These three questions are the most relevant ones. Games are decided on the weaker squares [1]; our opponent moves roughly as often as we do [2]; and your position can always be improved by bringing in the worst placed piece, or by preventing your opponent's worst placed piece from getting into the game or being exchanged [3]."

    I suspect that if we apply this set of questions, in a relatively short time we will need to find other questions to ask. That repetitive process is implicit in an improvement spiral.

  4. You need a set of standard plans for each situation. There are only about 50 tactical themes, and every theme has three or for scenarios. Often these scenarios are the same. Add attackers, eliminate a defender, win a tempo and the like. When you start to absorb these tactical scenarios, you fill your toolbox. The next question is: what am I going to make with these tools. For what am I going to use them?

    The answer to this question is limited. You are going to attack on a certain part of the board. And the amount of scenarios to attack is limited. You need a set of plans for the uncastled king, the king that is stuck in the middle, the king that has castled kingside, that has castled queenside, that has finachettoed, a minority attack, a majority attack, a pawn break and the like. The amount of plans is very limited, but the amount of ways you can execute a plan is endless, of course. But you need a set of standard scenarios first.

    How can you know that you have absorbed an insufficient amount of standard plans? You can measure it with the clock. If you start to use an unreasonable amount of time, then you have no clue. If you have no plan for how to handle an endgame with pawns at two flanks, and you cannot decide where your king must go, you are clueless. And when you are clueless, you cannot find the best plan by calculation behind the board alone. Calculation is for checking if your plan is possible, not for creating a plan by trial and error. Without a plan, you cannot know what is the best places for your pieces or which pieces to exchange. The clock doesn't lie.

  6. PART I:

    Game 2:

    Overall question: At what point(s) did you feel like you had no plan or even an idea of how to proceed?

    Please note: my comments are based on my impressions and may be totally off the mark. It is virtually impossible to get inside someone else’s head regarding their thoughts during a game. It’s sometimes difficult for me to even figure out what’s going on inside my own head!

    1. d4 Nf6 2. Nc3 d5 3. Bf4 c6 4. e3 Bf5 5. f3 e6 6. g4 Bg6 7. h4 h6 8. Bd3
    Bxd3 9. Qxd3

    You have a lead in development and more space on the kingside with the potential to break open some lines there.

    9... Bb4 10. O-O-O

    Question: Why not bolster the WNc3 with 10. Ne2? Black’s only immediate means of increasing pressure against WNc3 is with … Qa5 with a ‘threat’ to disrupt the pawn structure in front of your king.


    10… Nbd7 11. Nh3

    Question: What was your plan here? 11. Ne2 would maintain control of c3 and also indirectly provide a defense of the a2-pawn. The WNe2 would ‘defend’ f4 and potentially allow it to be occupied in support of the pawn advance. Additionally, the line of the WRh1 would not be blocked. Prophylaxis on the queenside and in the center, combined with potential aggression on the kingside.

    11… Qa5 12. Kb1 (tactically forced to avoid losing the a2-pawn) 12… Nb6

    At this point, Black shows his hand: he intends to ‘attack’ your king with three pieces, possibly adding pawns to the mix if/as needed while ignoring your kingside pawn storm. [Three piece ‘rule’: one piece to sacrifice, one piece to protect the mating piece and the mating piece – mating threats can materialize quickly.] If he can get the queens off the board, he will have the opportunity to castle queenside and open up the c-file with pressure on your castled position.

  7. PART II:

    13. g5

    Black has the opportunity to sacrifice here with 13… Bxc3, allowing 14. gxf6. Then he adds the third piece with 14… Na4. Things get tactically ‘interesting’ at this point because the Black queen and knight work together quite well to create potential mate threats. Black took a different route, trying to get all three pieces in place.

    13… Nh5 14. gxh6 gxh6 15. Be5 O-O-O

    Black had the opportunity to equalize here with 15… Bxc3 16. Bxh8 Na4 (Again, notice the excellent coordination between the Black queen and knight.)

    16. Bxh8 Rxh8 17. Nf4

    Question: Why not 17. Ne2? It removes the possibility of the exchanges on c3, and moves the knight toward the kingside, possibly allowing either knight to go to f4 without the possibility of Black doubling the f-pawns. Since the g-file is the only open file and Black already has lost the exchange, it seems that the g-file would be a natural avenue for penetrating into Black’s position. It looks like the initiative might have shifted to Black at this point – or maybe I’m seeing a mirage.

    17… Nxf4 18. exf4 Nc4

    Although you are up an exchange, Black is forcing play around your king while his own king is perfectly safe. Since you have taken no steps to occupy the open g-file, he doesn’t have to worry about his king for the time being.

    19. Ne2 Qb6 20. Qb3 Rg8

    I wonder if he considered 20… Nd2+ 21. Rxd2 Bxd2, regaining the exchange? If the queens come off, Black should have some advantage with control of the open g-file and a bishop versus knight with no good points for the knight in the center.

    21. c3 Rg2

    Nice tactical awareness. WNe2 is hanging, and b2 comes back into play, this time with the combined pressure of BNc4 and BRe2 (if White captures on b4). That strong BNC4 combined with the BR on the 2nd rank balance out being down an exchange. White’s major pieces lack coordination.

    The rest of the game:

    22. Rhe1 Be7 23. Qxb6 axb6 24. b3 Ne3 25. Rd2 Nf5 26. Rg1 Rh2 27. Kc2 Bxh4 28. Rg8+ Kd7 29. Nc1 Rh3 30. Nd3 f6 31. Re2 Rxf3 32. Rb8 Nd6 33. Rh2 Kc7 34. Rh8 Nf5 35. Kd2 Bg3 36. Re2 Kd7 37. Rh7+ Kd6 38. Rxb7 Bxf4+ 39. Nxf4 Rxf4 40. Rxb6 e5 41. dxe5+ fxe5 42. a4 e4 43. a5 Kc7
