Developing a sense for the initiative

Now the ToS is simplified, it is time to get a sense for this way of looking to the position. To describe it in those terms.

Black to move

r3kb1r/2qn1pp1/p4n2/4pNB1/1p3P2/6N1/bPPQ3P/2KR1B1R b kq - 0 1

In terms of the tree of scenarios:
  • Target: The king and queen look juicy
  • point of pressure:  c2; b3
  • line of attack: c-file
  • function: c2 defends king and b3 (overworked)
  • immobility: King has Lack of Space; c2 is pinned; K and Q are at a knightforks distance

Plan: add attacker to b3

Cashing in: it becomes apparent that  you not only have to look for counter attacks when you want to cash in, but at any moment that you don't make a double function move. When you potentially give the initiative away. Due to the multiplex immobility you can permit a move that hasn't a double function. That isn't a two headed monster. (1. ... Nc5)


  1. Its one thing to describe a solution, an other thing to find it. I think it might be more important to find the reason why this puzzle is so hard:

    Some possible reasons are

    Target: Rh1 ( and Kc1 ?)
    line of attack: diagonal h1-a8 and then eventually a-file for the queen with chackmate at the backrank


    you dont want to move the Nd7 because it looks like its dangerous..


    Nc5 is a silent move but the position seems to need a stronger move because of black possible Nd6+


    Its necessary to get ridd of such wrong ideas quick to be able to focus on the right ideas

    1. "Its one thing to describe a solution, an other thing to find it."

      Usually I try to describe how the find it. I want to do it different this time. In stead of to put my already overly trained slow logic brain at work and make it bulkier, I try to educate my unconscious mind by just showing it the essence.

  2. It looks like there are three possibilities on the ToS that might apply.

    (1) diagnosis -> immobility -> Lack of space

    (2) plan -> lack of space -> Squeeze the box

    (3) methods -> exploit immobility

    The "cue" (for me) is the immobility of the White King - it has NO legal moves, i.e., it is already in the "box." That immediately brings to mind - how to attack the White King as fast as possible. The Black Queen is already engaged in pinning the c2-Pawn.

    There are two available Black pieces for adding additional attackers to the "box." The Black Rook (a8) can add to the pressure on c2, but that still does nothing to attack the White King with a check. That leaves the Black Knight at d7. It just "happens" that there is a juicy square (b3) from which the Black Knight CAN give check. So, 1. ... Nc5 rapidly comes into focus as a very significant second-order threat.

    What can White do in the interim? Nothing, really. It will take at least one move to open up an escape from the "box." Intermezzo moves (such as 2. Nd6+ Bxd6) do not change the "box"; it is still locked shut around the White King. Because of the BBa2, capturing the b4 Pawn (2. Qxb4) does nothing to open the "box"; Black can still play 2. ... Nb3+ (reinstituting the pin by the Black Queen AND zapping the White King inside the "box." White has no choice but 3. Qxb3 Bxb3, losing the Queen for a Knight.

    So, it looks like scenario (2) is the operative one. After considering 1. ... Nc5, it begins to be apparent that there is a fork on the White King and White Queen on b3. Although the White Queen CAN move (somewhere), that Queen move will not relieve the "box" problem: the White King still has NO moves after the Black Knight lands on b3 with check, simultaneously closing off the "escape square" (d2) opened by moving the White Queen.

    I didn't even consider trying to "attack" the WRh1 along the a8-h1 diagonal (with, perhaps, 1. ... Qc6). Why not? Because it loses the initiative to 2. Bg2, skewering the Black Queen and Black Rook. Lack of King mobility is a much more important "signal" than attacking an isolated unprotected piece which can be protected (or moved) without adverse impact.

    When there is an immobile King with the "box" already formed around it AND there are at least two pieces "attacking" the "box", my approach is to look very long and hard at how to bring more pressure to bear against that King. Whatever piece(s) can be brought to bear must be thrown at it.

    On this point Alekhine goes so far as to say "all general considerations must be entirely forgotten" and "only that which contributes to the execution of the plan selected is of any avail." - E. A. Znosko-Borovsky, The Middle Game in Chess, pg. 60.


    (I love pithy sayings that have double meanings!)

  3. I experienced the fact that the Q and K are on a knightsfork distance as a form of immobility. 1. ... Nc5 was a move without tempo. But if it had been, there was no way to prevent the fork without the loss of wood.

  4. I'll explain how I looked at this problem.

    Minute 1: Seriously, another tactics problem? (Not you, my sentiment at the moment about every one seemingly suggesting that everything in chess is a tactics problem, and now here is a difficult one to solve).

    Minute 2-3: 1...b3, 2.c3 Qxc3, 3.bxc3 Bh3+, 4.Kb2 Rc1. Oh, wait, 3.Qxc3 prunes that branch. This is perhaps the biggest problem I have when calculating (and it just cost me my last OTB game) is applying the process of elimination. I will go unconstrained on some variation, only to figure out after much time spent that the whole line can be discounted at move one or two. It's as if I see long lines, and then maybe decide to blunder-check them - extremely haphazard methodology of analysis.

    Minute 3: Well, this is a tactics problem, and Black is in favor. hmm, no real immediate threats against Black, so what is this free ...Nd7 doing? Nothing, supposed to be attacking since it's a tactics problem and Black has been given the green light. So, 1...Nc5 and yes unstoppable fork, and 2.Qxb4 fails as well.

    Actually, I solved this problem in under three minutes - which would be a long time in a blitz game, and it's not saying much since in a real game one could be much more mentally tired OTB at this stage of the game, and there is no green light to terminate your opponent's position, only the instinct for survival at times.

  5. Hi Tempo,
    Back from my game bingeing and learning the Benko gambit. In looking at the problem and it solution ; it occurred to me the answer could also be arrived at by asking the principled question. How can I bring one more piece into the attack ? Cheers, Jim Takchess.
