For the first 11 moves the game is quite even. White has a slight advantage with a tight pawn formation and a strong forward Knight. With Black's castling and the ensuing exchange of peices puts
White well ahead so that by the end of the 15th move, Crafty gives White a +6.83 for taking the pawn (Qxe6+) which gains a pawn, a bishop and knight for a single knight. Unfortunately, White plays Nd7, giving away all the advantage gained by the exchange of pieces.

Black 17th move was to attack White's Queen. Better would have been to protect the pawn on e. This puts the game back in White's favor. White throws the advantage away by taking the pawn instead of the knight.

White's 20th move puts Black ahead by allowing black to fork the Rook and the Knight.

In the 23rd move, white should claim the C file. Instead a weak move that again puts Black in the game.

White's 24th move should have been to take the Rook and trade Rooks. Instead the Bishop is traded for Pawn.

White's 30th move should have been to move the rookout of danger and attack the bishop, rather than try and be fancy being a piece down.

Black used the advantage of the Bishop to kill pawns until White made a mistake in the 40th move. Resign.

White's 8th move should have been Qc7. This protected the queen provided coverge across the center of the board. Qe5 left the queen easily attacked. White's response (f4) further developed the center of the board and force the Queen to c7 anyway, losing a tempo for Black.


In the 11th move, Black should have concentrated on regaining the center, perhaps g5, threatening the supporting pawn on f4. By pushing the pawn to d6, the queen was unable to over the center of the board and White gained a big advantage

In the 13th move White left a pawn on the 6th row. Bad move. This moved the game well intto Black's field. Then in move 15 Qxe7 allows White to get the Queen. It goes downhill from there.

Hi,

I was playing this game as White. After the game I was using Crafty to analize the game. At this point, Black's 11th move, crafty puts White well ahead with a rating of +3.17. Also Crafty wants to move Bc7 but again I fail to see why that is such a good move.

So, what about White's position was so good at this point?

And, wht was moving the Bishop back to c7 good thing?

Thanks


Matt

I don´t have Crafty and I really can´t say why Crafty thinks White is a piece ahead. This evaluation would be true if Black moves 11...0-0 or something similar.

> And, wht was moving the Bishop back to c7 good thing?

It´s the most logical move. Black has to solve the problem of how to develop his locked in white squared bishop. To solve this problem, Black would like to push e5, freeing the diagonal. The bishop on c7 is ideal suited to support the advance of the e-pawn. Further, on c7 the bishop eyes White´s kingside (h2) and protects d6 from incursion of a knight.

For example: 11...Bc7 12. 0-0 0-0 13. Qh5 e5 and Black may be already somewhat better because of his bishops pair. White has of course 13. f4 so Black may consider e5 in the 12th move before castling.

11...Bb6 12. 0-0 0-0 13. Qh5 and Black has to play Bc7 anyway, giving White an extra tempo. Black has not the option of 12...e5 (13. dxe5 Nxe5 14. Ne4 Qe7 15. Nxe5 Qxe5 16. Nd6+ Ke7 17. Nxf7 wins).

Patrick v. Matt

Play a game with Patrick, I was Black

1. c4 f5 2. f4 e6 3. e3 Nf6 4. h3 Ne4 5. Qf3 Qh4 6. resign

White opened with the English Opening, Black responded with the Anglo-Dutch defence.

White then left both the center and the right side open to attack, leaving places for both the Knight and the Queen to occupy. With the combined threat to King, Queen, Bishop and Rook, White resigned.

Catalan Queen's Gambit

White's 4th move is not strong. It looks good but leaves the center open. Better to stay in the book.

White's 5th move is questionable. Better to cover the center pawns with e3. White's move is ineffective and leaves the center pawns vulnerable.

In the 6th move, the computer prefers taking the knight with the pawn (gxf6) rather than Qxf6.

Black's 8th move strengthens white's position. Black had a strong pawn formation and move waekens the formation.

Black's 11th move puts White well ahead. Crafty rates the board at +3.19. I am not sure why. Crafty perfered to pull the Bishop back to c7.

White's 13th move swings things back to Black's advantage. The pawn on b is left uncovered and now the bishop can capture the pawn put the king in check.

White's 15th move is questionable. It puts Black further ahead by pieces, but goes to open up the pawns in front of Black's king. (-3.23) White further weakens his position with the next move.

Black's 17th move puts White back in the game, somewhat. The computer preferred Q-g4+

With Black's move of the King to e7 in move 19, The game is back to even. The computer liked keeping the king more protected with Kd8

With move 21, White baits a trap for Black's queen, which Black falls into and lose the Queen.

Black's 24th move again leaves the king open to attack. Better may have been c7 with more protection for the King

White missed a couple of good moves on 25, 26 and 27. White should have brought the Queen into play instead of hampering the effort with the pawn.

Black's 30th move was the final blow. The game is quickly over.
