0       [Next]	COFFEY vs Fidelity Designer 2265 (speed game)
1       [Next]	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.
2       [Next]	You should put two pawns in the center when neither of them can be taken.
3       [Next]	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.
4       [Next]	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.
5       [Next]	The purpose of this move is break up White's strong center.
6       [Next]	Recaptures.
7       [Next]	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.
8       [Next]	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.
9       [Next]	Developing.
10       [Next]	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.
11       [Next]	Developing the knight to a strong square.
12       [Next]	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.
13       [Next]	Black's first mistake is that he should not block his queen bishop on c8.
14       [Next]	Now the knight can come to f3 without being pinned by the c8 bishop.
15       [Next]	Black develops, but is somewhat cramp.
16       [Next]	Pinning the knight makes even more sense after Black's bishop has gone to d6.
17       [Next]	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".
18       [Next]	Trading the bishop for the knight would only ease Black's crampness.
19       [Next]	Black cannot hope to castle kingside after opening up the kingside so much.
20       [Next]	Retreat.
21       [Next]	This is a serious mistake, as it opens a file for the White rook on h1.
22       [Next]	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.
23       [Next]	Necessary, as White was threatening Nf3xg5 which Black can't be take with h6xg5 because of Rh1xh8+.
24       [Next]	White's knight can't be driven from this post by f7-f6 without endangering the Black king to Qd1-h5+.
25       [Next]	Black is having a hard time putting his pieces on good squares.
26       [Next]	Concentrating on the weak "backward" f7 and h6 pawns.
27       [Next]	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.
28       [Next]	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.
29       [Next]	Notice that Black is moving his knight too many times.
30       [Next]	Castling helps activate the rooks.
31       [Next]	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.
32       [Next]	Necessary to prevent Qf2xb2 mate.
33       [Next]	Retreat. What should White do now?
34       [Next]	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.
35       [Next]	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.
36       [Next]	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.
37       [Next]	Mate in 2 coming up. What should White do next?
38       [Next]	Also Rf7-f8+ instead forces mate.
39       [Next]	Take the queen?
40       [Next]	No. Checkmate is better.
