Question

Chess,is it official that u have to capture your foes man even if it will cause u to lose a valuable man/queen

Answer 1

No.  Thatis the rule in some variations of checkers (or draughts) not chess.

Answer 2

If you have other options, then no, you don't have to make a move that will result in your piece being taken.  However, if it's the only move that will prevent you from being checkmated, then yes, you would have to.
