Attack and Defense

A man is said to ATTACK another man if he moves so that on his next move he could capture the other man. Thus, in Diagram 5, White could attack Black's Bishop by moving his Rook to d1 or to e6.

A man is said to DEFEND or to PROTECT another man if he moves so that in case the other man is captured by a hostile man he could recapture the latter. Thus, in Diagram 5, Black could defend his Bishop by moving his Knight to either e4 or e8 in case White attacks with the Rook from d1. Should White attack from e6, then Black would not defend the Bishop with the Knight, for on e4 as well as on e8 the Knight is unprotected and could be captured by the Rook without White losing anything in exchange. Black has a much more simple way to defend the attack of the Rook from e6, that is, by capturing the Rook with the Pawn f7. For this reason White would not have moved the Rook to e6.

Check and Checkmate

If a man makes a move which attacks the opposing King the King is said to be in "check." The player whose King is checked then has to make a move which gets the King out of check
