Ng4 or Nd7 will win the e-pawn. The d-pawn should always be moved in the first seven moves or so. Never be caught with it unmoved. It often pays to sacrifice a pawn by d5-d6 in order to prevent it from moving. Be careful about moving any pawns except the two in the center. They cannot retrace their steps. Two pawns in the center are strongest side by side. Advancing one of them may leave the other weak. The moving of any of the three pawns in front of the castled King may lead to weakness.
If one is already moved, be very chary of moving another. When your d-pawn is gone, castling on the Queenside is often good, since the Rook gets the open file at the same time. Moreover the King is nearer the center of the board for the endgame. The disadvantages of castling on the Queenside are: 1 The a-pawn is not defended by the King; 2 The King is exposed to a check on the diagonal. When your b-pawn has made a capture on c3, the Queen's Bishop need not be developed, since it threatens to come out in either direction, and this option should often be retained.
The Queen's Rook may take the open b-file. The following device should be known, since it may occur in more than one opening. Nf3 Nc6 3. Bc4 Nf6 5. Re1 d5 7. Bxd5 Qxd5 8. Nc3, recovering the piece and eventually the second pawn. If Black has made two non-developing moves in defending a gambit, and White none, White has the better game, even though he cannot recover the gambit pawn.
Example: 1. Nf3 c5? Here Black's second and third moves are both non-developing, and White should get the best of it by 4. The pawn advance to d4 is often an effective reply to Chances similar to this and the next occur fairly often. In the Center Game, after 1. Qxd4 Nc6 4. Qe3 Nf6 5 e5 Ng4 6. Qe4 d5 7. Bb4 pin. The Middlegame The object of the game is to mate, and as quickly as possible. Captures are made only to deprive the King of his defenses.
An attack on a well defended castled King must usually conclude with the sacrifice of a piece. All pieces, if possible, should be defended, and not by Knights.
A Knight which is the sole defense of an attacked piece is virtually pinned, for his misfortune is that he cannot move without undefending it. Beginners are especially fond of playing a Bishop to g5, defended by a Knight at f3, and attacking a Queen at f6. The reply Qg6 is usually feasible, and leaves the Knight immovable.
The Queen should usually be kept in the background till a promising attack is established. Avoid using her for hunting distant pawns, such as the b-pawn.
It takes two moves for the Queen to take it and get home again - if she can. Before playing Qxg7, attacking the King's Rook, see that the opponent cannot reply with Bf6, defending the Rook, and attacking the Queen and perhaps something else on the Queenside.
Beware of capturing the g-pawn or h-pawn in front of your castled King, unless your opponent has also castled on the same side. The Queen may sometimes pin one of two minor pieces. Thus, after 1. Bb5 a6 4. Ba4 d6 5. Nxd4 Nf6 7. Nxc6, Black can save loss of the Exchange, by Qd7, a device which is frequently overlooked.
Always be on the look-out for mates to follow a Queen sacrifice. Another is to play Qh6 when you have a Knight at f5 and a Bishop at b2, Black having castled on the Kingside. When you have a pawn at g6, the opponent's King and King's Rook being unmoved, look out for a chance of playing Qxh7, attacking the Rook.
For if Rxh7, then gxh7 often secures a Queen next move. Rooks should be played to the open files. If no files are open, positions on the back row opposite the opponent's King and Queen are generally useful, whatever may intervene.
Rooks should protect each other as soon as possible. Rooks are strongest when they are doubled on an open file or on the seventh rank; the latter usually means a winning position. A Rook is dangerously placed in the middle of a crowded board. A line of retreat should be left open. Taking Rxb7 is often a dangerous capture; the Rook may be bottled up by Bishop or Knight playing to b6.
Since there are obvious exceptions, the precept must be taken as referring to attacks of a speculative nature. However, one Rook has the possibility to access all squares on the chessboard. This is one reason why Rooks are worth more than Bishops. Additionally, rooks can also control more of the board at once, especially on the edges. When in a corner, a Rook controls all the squares of a rank and a file.
When a Bishop is in a corner, it's severely limited because its line of attack is only 7 squares diagonal. Rook is a higher piece value due to the Checkmate factor. The Rook has 14 Squares under its dominance and the Bishop occupies 7.
If it is put on a Central Square the Rook has still 14 and the Bishop has max So you see that Rook is much more worthy than the Bishop. I am not comparing any position where the relative value may be higher or lower. Sign up to join this community. The best answers are voted up and rise to the top.

Rewan Demontay It is good to remember that 1 a Bishop will allways be bound to the color of diagonal it was born, 2 Losing a Bishop will make you ineffective on a color of diagonal, 3 Diagonals have different sizes accross the board while columns and rows are always the same size.
A Bishop will have to conquer the center to have full effectiveness while the rook will have the same reach from any square of the board not counting here threats or movement block imposed by opponents — user Note: One bishop is worth 3 points, but having two of them on different colours, as usual gives you an additional Pair bonus of 0.

Active Oldest Votes. To see how you can compare two given pieces, let's consider your bishop vs rook question at a basic level: A rook's movement is not restricted to a color, unlike the bishop's. This makes half of the board squares inaccessible to a bishop. Assuming an empty board, the rook can always see 14 other squares from any other square, whereas a bishop's scope of legal moves varies between 7 to 13 depending on the square, the latter only reached when the bishop is centralised, something the rook doesn't care about!
Further, that it can jump over other pieces means it can defend without suffering a drop in offensive power. It has the potential to touch all 64 squares, as, on each move, it alternates between white and black squares.
A bishop functions completely differently from a knight. It is a long-range piece that moves diagonally and can swoop from one corner to the other if unimpeded. There are distinct situations where a bishop is preferred. For example, two bishops are better than two knights or one of each. Bishops are also preferable to knights when queens have been exchanged because, Grandmaster Sergey Erenburg, who is ranked 11th in the U. When forced to say one is better than the other, most anoint the bishop.
I've had a couple of situations arise where I had the opportunity to win the exchange but was hesitant because of an already-existing weakness on the light squares. The queens were still on the board and there existed a ridiculously open diagonal right to my king. I ended up winning both games, but it seemed to take quite a few moves before black's initiative ran out of steam and I was able to start trading off With a pre-existing weakness on the light or dark squares, I can understand why you might be a bit concerned about losing your primary defender of them there squares!
Recently I declined an oppertunity to force a complicated exchange that according to point value would have favored me a rook and two bishops from me for my opponents queen and remaining rook. I was even already up an exchange, but this complicated trade would have left my opponent with a passed pawn and me with no middle pieces to threaten it. It would have been a thorn in my side for the rest of the game. Position adds alot to value; that passed pawn would have immeasurable value!
Northern Lad. Originally posted by Learux There is a reason that a bishop is 3 and a rook 5 points! Learux It's best not to consider chess entirely in such material terms, even though that's basically what computers do! Of course, a rook is stronger than a bishop in most positions, not least because the rook is likely to be much stronger in the endgame.
However, my experience is that in many middlegame positions a bishop and pawn can be a rough equivalent of a rook. Interestingly enough there are situations where bishop is more valuable than rook e.
However these are quite specific positions. White to play and win Originally posted by thesonofsaul Recently I declined an oppertunity to force a complicated exchange that according to point value would have favored me a rook and two bishops from me for my opponents queen and remaining rook. The more complex and assymetrical the trade, the less one can use the point value to evaluate the trade.
