sharpest reply against d4

Najdorf or Dragon, I prefer Najdorf. 

According to stockfish 5 at 30 depth after 24... a6 the position is 0.00. So much for your refutation . Although I shouldnt be a hypocrite, I play this myself as white. Still black isn't busted if they are well enough prepared!

The sharpest reply to 1.d4 is the Englund-Gambit with 1...e5 (especially the Soller/Felbecker-Gambit after 2.dxe5 f6 and the Blackburne-Hartlaub-Gambit with 2.dxe5 d6,i dont like the passive main lines with Qe7).

A more "solid" reply is the Albins Counter-Gambit which was mentioned in other posts here.

A third option is the Baltic Defence 1.d4 d5 2.c4 Bf5 which can be extremely sharp after 3.Qb3 e5! or 3.Nc3 e6 4.Qb3 Nc6!, but can also be very lame and positional after 3.Nc3 e6 4. Nf3 c6.

All these three openings are my repertoire versus 1.d4...

dutch or KID both give black an attack in the kingside. KID is probably more complicated and more about tempos, you need to learn much more theory.

are you KID ?

I play the KID, and in redcredio's variation, 14...Kh8 is also good.

I play Budapest gambit all the time against d4

Maybe we shouldn't limit the responses to the "sharpest" reply, but good responses in general. Anything else?

1.d4 c5 leads to unusual asymmetrical positions.  One line, the "Dutch Benoni" (AKA Clarendon Court), continues 2.d5 f5.  Weird, and a bit risky for Black.

... SO MANY PAWN MOVES

Is it fair to characterize the King's Indian as a defense which accepts a losing position so rife with counterattacking possibility that the chances of exploiting a White error and winning are extremely high?

No its not.

Hardly...even Stockfish sees the dynamic compensation that blacks temporarily cramped position has, as it doesn't give out huge evaluations in white's favor in the opening like Houdini and to a lesser extent Komodo.  

The Englund never really feels that sharp or maybe I haven't encountered the proper variations:

Why not simply play a Budapest?  White only has a slight advantage at best if he manages to sift through the complications:

@XPLAYERJX, thanks for posting that Clarendon Court game, I enjoyed it.  Based on what I saw, you seem experienced with that defence.  Do you play it regularly?  I have studied GM John Levitt's DVD about it, and I play it once in a while with mixed results.  My chess expert friends tell me it is positionally unsound.  What do you think?

Anyone interested in the Clarendon Court/Dutch Benoni should have a look at the Clarendon Court defense group here on chess.com.

KID is probably the sharpest.

The Englund has been worked out to an advantage for white.

Against the Benko, white can play the b6 declined line where he plays, a4 a5, and neutralizes the initative of the two rooks.

The Benoni is always an option, though I dont find the threats on d6, or the prospect of white clamping down with a2-a4-a5 very appealing.

The Grunfeld is good, but extremely heavy theory wise.

While again, I prefer KID, sometime the Cambridge Springs variation of the Slav is wonderful, especially when your opponent does not know, the highly counter-intuitive move, which is the only move, that does not lose material. If he does stop your idea, you can always just go on with solid play.

The Dutch Benoni or whatever is complete bs

Is your opinion based on experience?  Not trying to start an arguement -- I sincerely want to know.  I've seen GMs and masters play it, so how can it be "complete bs"?

It might be ok as a surprise weapon, but the fact remains that Black's position simply isn't good after 2...f5...which is why nobody good uses it as more than a surprise weapon.

Okay fair enough (it is in fact rarely used, as you say).  I respect your opinion since you are a fairly strong player.  So, I'd like to know your opinion about the Dutch defense in general.  Would you say that any of the Dutch main lines are good enough to recommend to a friend?

I get the impression that many who play the Dutch think that 1.d4 c5 2.d5 f5 is just too risky.
