How the Chess Rook moves
The Chess Rook is called -a heavy piece- and loves open files and ranks. In your chess game never lock him away behind blocked pawn structures or let him fall asleep behind a silly pawn in the corner. In general he is stronger than a bishop or a knight.
Never exchange your rook for a bishop or for a knight in equal chess positions. You will have made a bad exchange and are at a disadvantage from then on. But if you can trade in your rook for the queen then do it as the value of a queen is roughly two rooks!
In a chess game rooks are developed later in the game. After the initial opening pawn moves, the light pieces (knights and bishops) move out first to exercise control in the center. After that the rooks move to the open or half-open files.
In a chess game it is a very strong plan, if you can double up two rooks on an important open file and control it completely.
Later on you might penetrate to the second (as black) or seventh rank (as white) from this position, which gives you positional advantage.

| The chess rook attacks the FILES and the RANKS. In this case the d-File and the 5th Rank. |
He can take the valuable queen or the bishop. A bishop has less value than the rook, so take the queen. The queen has a value of two rooks. You get the queen for FREE! That's good business! |
 |
 |
| The rook attacks the bishop. If you capture you will lose the R and get the bishop. Bad deal. Your R has more value. |
Here he has checked the King, he must move away OR the knight goes to f6, to block the check between the king and the rook. |
 |
 |
| The R attacks the pawn on d7. If he takes the pawn he will give check to the black king at the same time. |
The R could take the Pawn on d5. But the black Pawn will recapture and you lose the rook for a lousy pawn. That's real bad business, man! |
 |
 |
| The rook attacks the king.(gives check) He must move or protect himself in pushing the g-Pawn in between. After that you can take the b-Pawn for free. |
I am happy to give my R for the queen here! That's good business as the queen has a value of TWO rooks! |
