A pawn may move by vertically advancing to a vacant square ahead. The first time a pawn moves, it has the additional option of vertically advancing two squares, provided that both squares are vacant. Unlike other pieces, the pawn can only move forwards. In the second diagram, the pawn on c4 can move to c5; the pawn on e2 can move to either e3 ...
Exchanges can appear in connection with practically any kind of attacking or defensive chess tactic or combination of tactics. Such tactics can involve checkmating the opponent, avoiding checkmate, gaining a material advantage, avoid losing more material than necessary, helping a pawn to promote, preventing an opponent's pawn promotion, or setting up a draw by any of a couple methods.
The knight (♘, ♞) is a piece in the game of chess, represented by a horse's head and neck. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-files, each located between a rook and a bishop ...
some pawn exchanges may be necessary to open files, but keep pawns on both sides of the board; try to keep the position unbalanced. A passed pawn almost immediately becomes a winning advantage. [15] If the minor piece has an extra pawn (i.e. one pawn for the exchange), the rook should win, but with difficulty.
An isolated pawn on the d-file is called an isolated queen pawn or simply an isolani. [2] In addition to the open or half-open c- and e-files, the isolated queen pawn can provide good outposts on the c- and e-file squares diagonally forward of the pawn, which are especially favourable for the player's knights.
The Queen's Gambit is not considered a true gambit, in contrast to the King's Gambit, because the pawn is either regained, or can only be held unprofitably by Black. Black usually allows the pawn to be recaptured and uses the time expended to play against White's centre.
Except for unusual cases, the attacking side wins if the pawn is a knight pawn (b- or g-files) or a central pawn (d- or e-files). For bishop pawns and rook pawns, the result also depends on the location of the attacking king. If the attacking king is close enough to the pawn, it wins; otherwise a draw results. [8]
Most games featuring 1.d4 Nc6 transpose to other openings. After 2.e4 the Nimzowitsch Defense arises. After 2.Nf3 d5 a variation of the Queen's Pawn Game is possible. After 2.c4 d5 the opening is a Chigorin Defense. There are some lines that are unique to 1.d4 Nc6, most importantly 2.d5 which chases the knight away, usually to e5.
