Can't be answered simply, bishop ... there are four major choices for White in the French and Black's continuations are different in each case: a) Exchange (after 2.d4 d5 3.exd), b) Advance (after 2.d4 d5 3.e5), c) the Tarrasch (2.d4 d5 3.Nd2), and d) the Main Line (2.d4 d5 3.Nc3). Check out the Wiki article for more details on each: http://en.wikipedia.org/wiki/French_Defence.
Good luck with the French.
