The Petrov Defense with c6.

Is it possible within the Petrov Defense for Black to eventually aim to push the pawn to c6, is this goal for black good or bad? Provide an explanation.

Please provide a pgn to show everyone

You misunderstood the question, I wasn't actually showing any specific lines, just advice on general tactics, theory and strategy in relation to whether a c6 pawn push would be viable, although it would definitely be helpful if I was to be shown specific variations or lines showing a d6 pawn push from black under standard play from white.

 Still waiting for an answer.

   Your question is a bit vague. After 1.e4 e5 2.Nf3 Nf6, we're in a Petrov, but it's white's move. After just about any move white plays, black can reply c6. Is it "viable" depends on what white has played on move three. Just go into Game Explorer and check the line. After white's commonest third moves, Nxe5, Nc3 and d4, the reply c6 has been tried, with various results and a lot of transpositions.

I'm being very specific about what I knew and didn't know, learn the terminology.

Yet again you show no sign of having a clue about what I was talking about, when one side of the board aims for a particular move they are working towards a strategy that entails setting up the board in such a way as to utilise a certain square or a certain pawn being pushed towards a particular square for tactical and postitional value as well as for creating particular structures in the future.

there is nothing wrong with c6 at certain time, comparing to Nc6, white does not feel pressure with d4 or possible Nb4 where it must decide what to do with Bd3.

As black,  used to play ocasionally and somehow i missed above two with c6 setups, Nb8 has less active development... still at some average club levels, completely solid setup. 

You really need a pgn or this type of question, because it depends on the position, and what white does.
