Unfortunately -- actually, fortunately, chess is too deep to reward such generalized advice.

The Tarrasch is a pretty solid line; intrinsically, it's not the most active line, but it aims to consolidate the space white has, or else make a compromise -- in the 3...c5 lines for example black often liquidates the center but needs to catch up in development quickly. With Nd2 white's saying "I'm not charging forward right away, but if I take time out now to defend my center, at least it will still be there!" It's merely a slightly different strategy white undertakes -- by no means an inferior one. In fact, 3 e5 in practice tends to give black more opportunities to equalize, because it immediately commits to the attack-able pawn chain. Consequently, black is often able to undermine it a little more easily.

See how "aggressive" doesn't always equal best?

there's no excuse for playing nd2 ,when e5 availible take it every time. Between attack (E5) AND passivity (nd2) move forward....

i like this opening very much!!

How does the french not play for a win? At least besisdes the exchange variation, the french creates a big pawn chain struggle with dynamic counterplay.

I'll admit, I may not be the best player but I do like the French quite a bit.  I find it usually works pretty well for castling to either side and players don't really know any good traps to play against it.  It doesn't really play for a win without a blunder for white but it does play for a draw pretty well.

"I don't see the point of playing the French as black.  It is similar to the Caro-Kann but in the Caro-Kann you can get your bishop out so it doesn't become 'bad'.  Any French players want to explain?"

Yes. the point of playing e6 as opposed to c6 is that black doesn't want to exchange off his d5 pawn. Instead, he wants to attack white's pawn chain with ...c5. Alot of times (well in the advance variation which is better for black than this one) black actually ends up winning the center. with c6 you are just hoping that white can't make use of his space advantage but since black doesn't attack anything although his bishop is open he has less counterplay. white is under more pressure from the ...c5 and ...f6 moves than just exchanging pawns off in the caro-kann.

i think the knights seem a bit closed off. i mean to say they are on the deffenceive side

Qb6 may open up chance of attack for Black

Good representation.

 we must see the position....
