The sharpest or most tactical d4 opening?

Which is the sharpest or most tactical d4 opening for black? I think the king's indian is a good one but I hate the exchange variations.

perhaps the budapest opening

kings gambit dah other then e4 e5 d4 stuff

benko

wsry didnt read title but yah noteboom variation of semislav

but what if they play some exchange variation?

Botvinnik semi-slav's are pretty wild.

The Dutch Leningrad seems to be one that if White wants to fight for an advantage he must accept that it's going to be a wild tactical game..

don't post again ever antony

anthoney is by far in the top 100 of contributing members on chess.com you should not tell him to do anything lol and that is kinda rude especially since he is stronger then you as the rqatings say

The KID is primarily a strategic opening.  Tactics happen after preconditions have been met or serious mistakes have been made by either side.  Its not using the same 6-9 opening moves every game then throwing your pawns at white's king.

"..est" opening don't exist, best, sharpest, easiest, quickest, etc.  An opening may be more tactical or more strategic in general terms but all openings require an understanding of both strategy and tactics, even gambits.  That said, if you want to have the greatest reliance on tactics as black vs. 1. d4 you should look at gambit answers.  Albin countergambit, Blumenfeld gambit, Noteboom,  Englund, etc.  If you go this route you will need a couple as white may sidestep you. 

The Albin Counter Gambit is very sharp:

Gonnosuke gave the very best move-order above to get a sharp version of the Slav defence : you can thank him, as it took me more than 1 year to reach this conclusion !

Albin gambit is also an option to get a fighting game.

I would add Ben-Oni to the list : you can conjure up tactics in almost any variation as Black. Besides, the Ben-Oni is a very good practical weapon, as it's not very trendy.

As for the Nimzo, you could try to steer the game into tactical channels against most variations but maybe not all of them (for example 4.e3 is pretty positional).

And as you rightly mentioned, you can't always force a sharp struggle with KID : many variations are pretty positional too or make it difficult to get the same kind of counterplay than is the Classical (especially Fianchetto, but also Exchange var., Petrosian, 6.h3, Averbackh...). Actually, I've always considered KID as a rather strategic opening, as you must learn how to play on a whole board (queenside, center and kingside).

The problem with playing sharp openings and destroying everyone at your local club with them is that those players will start playing the "exchange" variation each and every time...making you weep and contemplate taking up backgammon.

I gave up playing the benko because everyone played 3.Nf3...

Now all I get against the king's indian is the classical exchange line...

I think maybe I should just play the dutch, or is there some lame-ass line people can play against that too?? 

Yeah there's always some really drawish line, in every opening. For example I play the semi-slav so I see the exchange variation alot, which is dull. But if a lower rated player plays the exchange against me I'm going to win, one because I'm a better play and because I have a better understanding of the opening/middlegames positions. If a player rated high than me plays the exchange, I should be able to get a draw, and if a player of equal rating plays it against me I should win because I'm underrated. Don't worry about the opening so much, if you play a drawish opening  and outplay your opponent in the middle and end game you should still win.

Well yea...

But still, I would rather have an interesting game from the very beginning and not have to squeeze out a win from an equal position. I would rather be slightly worse with lots of play than equal in a dead position!

 Amen to that! I hate boring draw's I rater give 2 pawns and give up :)

never

Yea that's more or less my only consolation. People fear my benko! mwahaha! 

I don't blame them though...I have an undefeated record with the thing over the board and have allowed only one draw. Still, they should book up, grow some balls, and challenge me in the mainlines like manly men.

 Victory comes from choosing the battlefield.  Why fight on ground (Benko) of the opponent's choosing?
