"control of the center creates momentum"
summary: in this match, we see how the control of center creates unlimited opportunity.
1. h2-h3 ...d7-d5
white opens with his rook-pawn, allowing black to take the initiative in controlling the center of the board.
2. d2-d4 ...Bc8-f5
3. e2-e3 ...e7-e6
notice how both players have made the same number of moves, yet white's queen-bishop is restricted, while black's developed queen-bishop reinforces control of the center.
4. Ng1-f3 ...c7-c5
white develops his king-knight, as a prelude to castling. black plays a delayed version of queen's gambit, and moves his queen-bishop pawn to c-5. this will allow black to develop his queen-knight, while (if white takes the gambit) allows black to develop his king-bishop as well.
5. Bf1-b5 (check) ...Nb8-c6
6. Bb5xc6 (check) ...b7xc6
white has placed black in check twice in a row, but has nothing to show for it (except an opportunity to castle early). black has the momentum in the center, and if 7. d4xc5, black will gain more of a stronghold while developing his king-bishop.
7. d4xc5 ...Bf8xc5
8. 0-0 ...Ng8-f6
9. g2-g4? ...Bf5-g6
white makes a (seemingly) harmless miscue by weakening his king's castle, and black's bishop retreats to safety. although black can castle on his next move, he might wait -- and take advantage of white's weakened position with a king-side attack.
10. g4-g5? ...Nf6-e4
white presses his attack, but black's response creates several problems for white:
- black's knight at e4 takes a powerful, forward position
- black's knight also attacks white's advanced king-knight pawn
- black's queen also attacks white's king-knight pawn, in a "discovered attack"
11. h3-h4 -- in an attempt to protect the pawn.
11. ...h7-h6 black begins the attack.
12. g5xh6 -white would have been better served with 11. N-c3, which would have helped to reduce black's stranglehold on the center.
12. ...Rh8xh6! (instead of 12. ...pxp). now black has provided his king-rook with a powerful attack lane, pointed squarely at white's depleted castle. white has a serious dilemma.
13. Rf1-e1 ...Bc5-e7
white is overwhelmed, and tries to create an escape route for his king. black simply steps-up the attack.
14. Re1-e2 ...Be7xh4
white braces for the inevitable, and black delivers. one look at the board tells the story:
black's pieces are developed, synchronized, and synergistic. white's pieces are restricted, undeveloped, and out of the game.
15. Nf3xh4 -what else can white do?
...Qd8xh4! black patiently saves the development of his queen for the moment of choice -- when she can unleash her power, fully!
16. f2-f3 -white is completely out of options...
black's superior development, patience, and control of the center coincide to create a punishing mate. in the end, white lost because:
- white failed (at the outset) to bolster his center.
- white mounted consecutive advances (which might have given him some instant gratification), but he forgot to lay the groundwork for security and stability.
