I have a question regarding <i>en passant</i>. I have heard that each player may only capture <i>en passant</i> once per game. This would seem to be supported by the wording the <a href='http://www.research.ibm.com/deepblue/reference/html/i.2.e.html' target='_NEW'>chess glossary</a> at IBM's site on the Kasparov/Deep Blue match: "<b>En passant:</b> (In passing) A special pawn capture which can only be effected once by each side in a game...." But I had always heard before that you may capture <i>en passant</i>, even if you have already done so before in the game (with different pawns, of course). <p> I understand that once an <i>en passant</i> move becomes available, you must either do it that turn or pass up the opportunity to capture that pawn via <i>en passant</i>, but if you <b>do</b> capture, can you still capture <i>en passant</i> later, if the same situation (with different pawns) were to come up again? What if you <b>don't</b> capture?
