  • COFFEY vs Fidelity Designer
  • 2265 (speed game)

  • The Caro-Kann defense is one of
  • Black's stronger replies. It
  • prepares to put a pawn in the center
  • with d7-d5. It has an advantage over
  • the "French" e7-e6 in that there is
  • no pawn on e6 to block the Black c8
  • bishop.

  • You should put two pawns in the
  • center when neither of them can be
  • taken.

  • Black has only one pawn in the
  • center, but it is better supported
  • than either of White's pawns. White
  • must do something about his attacked
  • pawn.

  • White defends his pawn that was
  • attacked. This will probably lead to
  • the exchange of pawns and a semi-open
  • game. Possible instead is e4-e5 that
  • leads to more of a closed game.
  • Since there are no open files to
  • place rooks on, eventually both sides
  • will have to try to create open
  • files.

  • The purpose of this move is break up
  • White's strong center.

  • Recaptures.

  • This knight move prepares to play
  • Ng8-f6 without a risk of doubling
  • pawns. It is more common to see
  • Ng8-f6, but after Ne4xf6+, Black's
  • pawns get doubled. Black would
  • either play e7xf6 keeping his pawn
  • chain intact, or instead g7xf6 so
  • that he can have a semi-open file to
  • attack on the kingside, but at the
  • cost of isolating his rook pawn.

  • With this move, White is waiting to
  • put his knight on f3 until Black
  • commits his bishop on c8 to a square.
  • Thus he avoids having his knight
  • pinned to f3 that might eventually
  • want to go to e5 or g5. I don't like
  • c2-c4 as much because White may then
  • have to go to extra effort to keep
  • his d4 pawn safe. Although a pawn on
  • c4 would exert more control on the
  • center, White has the option of
  • playing c3-c4 later. The c3-c4
  • maneuver might be useful later if
  • Black tries to put a knight on d5.

  • Developing.

  • It is either take or move the knight.
  • Defending the knight with Bf1-d3
  • Nf6xe4, Bd3xe4 Nd7-f6, Be4-d3 doesn't
  • seem too bad, but White may want to
  • wait to commit his biship to another
  • square besides d3. What is wrong
  • with Ne4-g3? I don't know.

  • Developing the knight to a strong
  • square.

  • This is book according to BCO2. But
  • in view of what happened in this
  • game, the bishop would have been
  • instead just as well off on d3.

  • Black's first mistake is that he
  • should not block his queen bishop on
  • c8.

  • Now the knight can come to f3 without
  • being pinned by the c8 bishop.

  • Black developes, but is somewhat
  • cramp.

  • Pinning the knight makes even more
  • sense after Black's bishop has gone
  • to d6.

  • Only accomplishes creating a weakness
  • in the Black kingside. If Black
  • castles kingside, White might use the
  • h6 pawn as a target in a kingside
  • attack. There are some good examples
  • of this in the book "Logical Chess
  • Move by Move".

  • Trading the bishop for the knight
  • would only ease Black's crampness.

  • Black cannot hope to castle kingside
  • after opening up the kingside so
  • much.

  • Retreat.

  • This is a serious mistake, as it
  • opens a file for the White rook on
  • h1.

  • Now White isn't planning to castle
  • kingside either because he has a very
  • strong rook on h1 that is working
  • against a "backward" Black pawn on
  • h6. A pawn is said to be "backward"
  • when it can't be defended by other
  • pawns.

  • Necessary, as White was threatening
  • Nf3xg5 which Black can't be take with
  • h6xg5 because of Rh1xh8+.

  • White's knight can't be driven from
  • this post by f7-f6 without
  • endangering the Black king to
  • Qd1-h5+.

  • Black is having a hard time putting
  • his pieces on good squares.

  • Concentrating on the weak "backward"
  • f7 and h6 pawns.

  • Forces White to do what he would have
  • done anyway! Instead of moving this
  • piece for the third time he should
  • make preparations to castle.

  • White's threat is to play Ne5xf7!
  • Then Black couldn't respond with
  • Qf6xf7?? because of Bd3-g6! pinning
  • the Black queen to the King. Notice
  • that none of Black's other pieces can
  • come to the defense of the f7 pawn.
  • If Black were to play Rh8-f8, then
  • the h6 pawn would drop.

  • Notice that Black is moving his
  • knight too many times.

  • Castling helps activate the rooks.

  • Greed. Black needs desperately to
  • complete his development. It is
  • rarely a good idea to attack when you
  • are behind in development. This
  • shows that the computer has a
  • complete disregard for the safety of
  • its King. I doubt that a human
  • Master would have made the same
  • mistake.

  • Necessary to prevent Qf2xb2 mate.

  • Retreat. What should
  • White do now?

  • Might as well add another piece to
  • the attack! This is better than
  • Ne5xf7 as
  • White is going to win the pawn
  • anyway. Consider Black dead now.

  • No good place to go.
  • Which way should White take the f7
  • pawn? I have asked many
  • students this question, and I usually
  • get many different answers.

  • This is the best way to capture the
  • pawn as it threatens the queen while
  • it threatens discovered check from
  • the queen on h5 by moving the rook.

  • Mate in 2 coming up. What should
  • White do next?

  • Also Rf7-f8+ instead forces mate.

  • Take the queen?

  • No. Checkmate is better.
