d4

what is the best opening for black against d4 ???

Probably one of these:

1...Nf6

1...d5

1...e6

1...f5

1...g6

1...d6

1...c5

or

1...c6

But I say probably because it might be 1...Nc6 or 1...b6 as well.  Hard to go too far wrong, unless you're playing ...h4 or ...Nh6 or something.

Whatever the flavour of the week is at the top level.

What do you mean the best? Depends on your strategy. But, anyway, this is what I do: I attempt to bait whites d4 with my c5 pawn- 65% of players take the bait and attack it. I lose a pawn, then my next move is to be d5 to begin my take over of the middle  board  followed by d4; a pawn on the 5th rank. Then ive adapted several ways to defend  its position while maintaining my defense of my king. It all works great, its just my end game that falls through. But that is what I do, it's a very un-normal opening but it is effective 75-80% of the time.

Play on dude!!!!

 I like that too!!

can you name the openings so i can look them up? 

thank you

Try the Nimzo-Indian Defence.

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4.

This of course depends on your opponent's 2nd and 3rd moves.

thank you jesse for taking spending your time to help me out.

the ansers to your questions.

1) im aggresive player, like the attacking style.

2)i like to devlope my pieces till the rooks are connected, and then go on to attack.

3)im not playing chess to become a GM or anything, i found it to be a good way to spend my free time. i addopted it as my hobby, so now i play chess whenever i get time.well my priority is to have fun , but then of course, i'd like to get better, otherwise i wouldn't have asked  this question in the forum.

hope you can help me out :)

thank you

PS, what im currently using is the dutch stone wall, but im not really good at applying it, and tends to loose most of games when i play it

Have you ever tried the Leningrad Dutch?  I think it's more interesting than the Stonewall, but it can be nerve-wracking to play. 

When I was just starting out in chess I got very good games using the Cambridge Springs variation of the Queen's Gambit Declined. It's easy to learn and fits your description of the way you like to play chess.
