Game 3, GW-KW v. Fritz 12 (Level 5), for Control of the Center
[July 4th 2011]


Commentary

RECENT MOVES: 17. N1d2 e5

(GW, July 4th) PROPOSED MOVE: 18. d5

Reasoning:

  • 18. d5
    Gets us an Advanced, Protected Passed Pawn, putting Black's Nc6 under direct attack. I'd expect Black to move this Knight and then we can play 19. e4, creating an Advanced Salient (c4,d5,e4), with the e4-pawn protected by 3 units (Nd2, Qe1 and Bg2). Our e-pawn advance would block Black's e-pawn, which has been threatening a further advanced down onto the 4th Rank.

Ken's Comments ...

(KW, July 4th) This move also makes both Bishops bad, and will force the Black Knight away from its strong spot to an inferior one.
  • 18. Ne4
    This could result in 18. ... Nxe4 19. Bxe4, but then my brain begins to stall on Black's 19th move.

Ken's Comments ...

(KW, July 4th) This move might be a candidate move for move 19 or 20, but not the best here.

(GW, July 4th) I propose 18. d5, as it seems more solid.

Ken's Comments ...

(KW, July 4th) I am puzzled by Black's move, but pleasantly puzzled. Black is relieving the tension in the Center after an entire game to this point of enhancing the tension. By this move of Black's, and by our move d5, White gains control in the Center.

Let's look at how White has Control of the Center:
  1. d5 will be occupied by White's Pawn and protected by the c4 Pawn and Bg2. (+1 for White)

  2. e5 will be occupied by Black's Pawn and defended by Bd6 and Re8, and have the potential of defense by f7-f6 once the KN moves. Once d4-d5, White will influence d4 with Bb2, and has the potential of offense with f2-f4. However, at this moment Black has a Control Advantage over e5 (let's call it +.5 for Black)

  3. d4 is still disputed, with c5 and e5 Pawns and Qb6 influencing d4 for Black, and e3 Pawn and Nb3 Bb2 influencing the square for White. Black will find it difficult to place a Knight on d4, especially in the next 3 moves.

    The Knights will need at least that much to arrive at d4 (Nc6-e7-f5-d4 or Nf6-d7-f8-e5-d4). Black cannot move the current Nc6 to d4 as he will lose the exchange. No other Black Piece is able to get to d4 in the next few moves.

    As Black cannot move a Piece to d4 without losing the exchange, and cannot move a Pawn to d4, while White can control d4 and has the advantage of being able to move through it unimpeded (Black has nothing around able to do even that), White has a slight advantage in Control, even though there are two Black pawns on c5 and e5. (Let's call it +.5 for White).

  4. e4, finally, will be a source of contention for the next couple of moves after d4-d5 (this is really the only square in the Center that can be attacked by a Pawn), however White Controls e4 now (2 Pieces to 1 = +1 for White). White will have the option of either e3-e4 or Nd2-e4.

So to sum up, White controls d5 and e4, and it's about even between d4 and e5. Add to that the Advanced Salient, Protected Passed Pawn, the inability to immediately challenge the Center, and:

White has Control of the Center

I agree, the move to make is 18. d5. White has an advantage that should win the game.

SELECTED MOVE: 18. d5
