The top board at the university I attend always answers 1...d6 to everything and always strives for Philidor-type positions like the one in the diagram below. And if a line like e4 d6 d4 e5, if white decides to exchange pwns then queens, white will have very few winning chances (if any) against a good defender.
Above is the general development of the Black side - such a setup is not very easy to attack. Black aims to attack on the Qside or in the center and often will develop the bishop to b7 or a6.
Originally posted by YugaGM Andrew Soltis wrote a book recommending that Black play 1...d6 against all moves. For a while, GM Joel Benjamin often played this line as Black, also recommended by Soltis in the above book: 1 e4 d6 2 d4 Nf6 3 Nc3 c6 4 f4 Qa5. Benjamin gave up on this system after GM Walter Browne crushed him in the 1995 or 1996 U. S. Championship.
