* ROOK: Rooks must have open lines. This may take some time to arrange, and because they can be chased by minor pieces they are best place in waiting (like the Queen) on the central e- and d-files. Later, they can move strongly up the board using these central files - for example, in the middle game, to e3 and then move over to g3 to help attack the Black King, or right up to the seventh rank on e7 or d7, where it can attack pawns right along the opponent's second rank. This control of the seventh rank is very powerful, particularly in the endame if your opponent's King is stuck on the last rank (a8-h8). Rooks work even better in pairs - for example, by putting them on e1 and e2 they can control the e-file and then often Black cannot swap off by playing their own Rook to e8. Even stronger is to control the seventh rank absolutely with eg. Rook on d7 and e7, where they can gobble up pawns and often Ks.
