B-Method Self-Examination

First, let me say that I make no claims to the accuracy of the following analysis of this game. The goal of this article is to articulate and demonstrate 'how' to use the "B-Method" during play. I make many assumptions during this analysis, and the plan I undertook during the game could easily be the incorrect plan given the specifics of the position. However, I do hope that it serves as a fairly clear example of how to implement the "B-Method" in your games.

This game was played from May to July 2009 on an email server, so it serves as a good training ground for using the "B-Method", as I am able to make notes into Chessbase as I ponder my moves over the course of the game. The opponent will remain anonymous, and I will pick the game up at move 27. As is required for using the B-Method, this game is considered from only one side - Black's perspective.



27.Rexc2
Ok, let's begin this exercise with a quick review of the B-Method Squares Strategy.
Essentially, you, as the player of the pieces from whose perspective the position is being evaluated from, in this case, BLACK, have the task of answering, at first, the three vital questions posed by the B-Method:

The Strategy Question (SQ) - the central square from which your strategy focuses from - the specific area you are defending.

The Direction Question (DQ) - Which direction are your pieces cooperating in from your selected Strategy. You generally look at the influence of your pieces here - Pawns, Knights and Bishops primarily.

The Color Question (CQ) - which color squares should you be trying to play actively on? It stands to reason that you can answer this question best by what color squares your opponents' pieces defend the least.

These three questions give you a basis from which to understand which of your opponents' pieces are in conflict with the given strategy chosen -that is, what pieces you need to Put to Question (PQ) to advance the strategy. This should lead you to develop a list of Candidate Moves (CM) - moves that advance the strategy, and analysis and calculation should give you the 'best' move as the Game Move (GM).

SQ: Strategy Question: e5-Strategy. Black has chosen the e5-Strategy as he is defending the e5-area from attack. As a pawn sits on e5, this would also be considered a "Pawn Strategy" from e5. In B-Method shorthand: +S(e5...)

DQ: Direction Question: f4. Here it is important to note what squares your pieces cooperate on. In this position, the Bb7 and the Knight maneuvers Qf5 and Nf4 all place the black pieces in position to attack in the f4 direction. +S(e5>f4,...)

CQ: Color Question: White squares. Black Bb7 and Nd5-f4/Qf5 cooperate on the white squares. It's important to note here, generally speaking, with bishops of opposite colors you would want a strategy that takes advantage of your own bishops' color. +S(e5>f4, wsq)

PQ: Put to Question: Which white pieces defend the white squares that we are attacking? These squares are namely e4, f3, e2, g2 and d3. the White pieces that defend those squares are Pg2, Nf3(to e1), and Qh4. Those are the pieces we want to 'put to question', i.e., attack and divert or trade off. Also note that the white Bishop is essentially invisible to our white-squared strategy. +S(e5>f4, wsq), >> Nf3,Qh4,Pg2

CM: Candidate Move: Queen is threatened, so a queen move is indicated.
CM1: Qf5 attack the light-squares e4/f3/d3 and it cooperates with Bb7 and Nd5-f4.

GM: Game Move: Qf5

27...Qf5 28.Bc5


This time, more briefly:

SQ: e5-Strategy (same)
DQ: f4 (same)
CQ: wsq: (f3, g2,e4,e2,d3); Nd5/Bb7/Qf4 work on wsq; Pg2/Nf3/Qh4 defend wsq;
+S(e5>f4,wsq)>>(Pg2,Qh4,Nf3)
CM: Nf4

28...Nf4 29.Ne1


SQ: e5-Strategy (same)

DQ: f4. Black wants to control/occupy f4,g3,h2 and attack e4,f3,g2. Black's pieces cooperate against g2,f3,e4,d3. Therefore, pursue the e5-strategy towards f4. +S(e5>f4...)

CQ: What color do the white pieces cooperate on?
The Black pieces cooperate on Black squares: Qh4, Bc5 - this shows white-squared weaknesses. The White pieces cooperate on White squares: - wsq: Nf4,Qf5,Bb7; Therefore, Black should strive to attack the white squares and aim for a white-squared initiative.
+S(e5>f4,wsq)

PQ: Black should look to those pieces that are defending the white squares (Ne1,Pg2) and seek moves which tangle them up in play ('Put to Question'). These are your candidate moves.

CM: Candidate Moves
CM1: Ba6: threatens Ne2+ winning the exchange; easily parried by Kh1.
CM2: Be4: threat Bxc2 winning exchange;Red8: occupation of the open file. this seems to froce the Rook to b2, a better square to meet a minority attack by black on the queenside and supports the push b4.
CM3: Rac8: Rook to open file and pinning the Bc5 to Rc2; This may induce white to play b4, weakening his Q-side pawns by the mere fact of their advancement, making them susceptible to a minority attack on the Queenside.

All three lines are analyzed. Your responsibility is to select the move that meets the needs of the position the best.

GM: Rac8 - I chose this move because it brings the out-of-play Ra8 into the game and adds pressure along the c-file.

29...Rac8 30. b4

As you can imagine, if the pawn structures do not change, in general, your strategy would probably stay the same. But always be on the lookout for an improvement in target-setting and strategy!

SQ: e5
DQ: f4 direction
CQ: Black pieces coop on wsq; White pieces coop on bsq; +S(e5>f4,wsq); Pg2 (weak), attack(e4,d3);
CM:
CM1: Be4:attack Rc2, square d3.
CM2: Ba6: threaten Ne2+, winning exchange.
CM3: a5: minority attack on queenside.

GM: a5 - I chose ...a5 because it seemed the most consistent plan at this point as it removed the a-pawn from attack on a7 and will allow an eventual ...Ba6, also consistent with a white-squared strategy.

30...a5 31.a3 [ 31.bxa5? g5 32.Qxh6 ( 32.Qg3 Rxc5) 32...Rc7-+]


SQ: e5
DQ: f4 direction
CQ: Black pieces co-op on wsq; White pieces co-op on bsq; +S(e5>f4,wsq); Pg2(weak), squares e4,d3;

CM: Candidate Moves
CM1: Ba6; pressurizes white squares in white position (d3,e2); threat Ne2+.
CM2: Be4; threatens Bxc2, winning exchange.

GM: Ba6 - continues the attack on the white squares d3 and e2.

31...Ba6 32.Kh1

SQ: e5 (same)
Now here, according to my notes, I changed directions with the advance of e4. Is this correct? I cannot say for sure either way, as both strategies have their plusses and minuses, but the end result bore it out. I felt the change was warranted due to the major weakness of the d3-square in white's camp. It also illuminates the fact that you have to always be ready to change stride if the position presents itself. From a color complex point of view, it seems consistent as Black is still playing on the white squares - squares that White has the most trouble defending.
DQ: d4 direction
CQ: White squares: +S(e5>d4,wsq); Sqs: d3,e2,c2,e4;
PQ: Put to question the pieces Ne1, Rc2;
CM:
CM1: e4 - gains space, attacks f3,d3.
CM2: Ne2 - attacks Rc1

GM: ...e4

32...e4 33.Rd1

White's last move seemed to be not the best, leaving the Rc2 vulnerable, but it is a difficult position to play. He is slowly being squeezed.
SQ: e5
DQ: d4
CQ: wsq +S(e5>d4, wsq); d3,e2,c2;
PQ: targets: Rc2, Ne1,Rd1;
CM:
CM1: e3 - Now possible because Bxe3 cannot be played due to White's last move.
CM2: Red8 - Black can grip the light squares with this move followed by a4 and Nd3.

GM: ...e3 - Black chooses this move as it appears to be more to the point and results in a passed e-pawn for black.

33...e3 34.f3


SQ: e5
DQ: d4
CQ: wsq; White defend the black squares - Qh4, Bc5;
PQ: Ne1; Rd1; Pf3;
CM:
CM1: Bb5 - threaten Ba4, winning exchange.
CM2: h5 - takes the g4-square away from White's queen. White's queen is now in peril.
CM3: axb4 - this exchange is unecessary at this point and is not forcing enough.

GM: ...h5

34...h5 35.Qg3



SQ: e5
DQ: d4
CQ: wsq; White defends the black squares - Qg3, Bc5;
PQ: put to question the pieces Ne1, Rd1, Rc2;

CM:
CM1: Bb5 threat: Ba4; idea axb4, Ra8 occupy open file;

GM: Bb5

35...Bb5 36.Rb2 axb4 Black Resigns [1-0]



Black resigned at this point, probably not looking forward to more moves of tiring defense.

A simple example that was pretty clear-cut from the Black perspective. Black, in a position with Bishops of opposite color, chose to play on the wihte squares (his own bishops' color), and was able to dominate white in the center of the board. Meanwhile, White could not generate any meaningful counterplay on the black squares nor defend his white-squared weaknesses for long.

I hope this simple example gives you some idea of how powerful the Squares Strategy B-Method can be if used correctly (did I use it correctly? Only Bangiev can tell me!). Color complexes play an important role in nearly all chess games, and the B-Method has at it's core a color complex-based strategic system.

Keep on Checking!
