French Tarrasch

You better check again!  My claim is that 3...c5 nullifies 3.Nd2?!

You probably stopped at 3.Nd2?! And see percentages based on the 117 games that I played Black on this site.

However, my claim is that 3...c5! Is the Tarrasch Killer.  You will see only 89 of those 117 games did I play 3...c5!, and there, my numbers are BETTER, NOT WORSE, than 3.Nc3.

My claim is that other moves are worse, and the stats of the 28 games where I did not play 3...c5 just back up that statement!

That said, even then, internet blitz is garbage!

Tarrasch is nothing after c5 @ThrillerFan is right

There is no such a thing as nothing, a lot of people like to play the Tarrasch as white and it isn't really refuted, I as a french player am covinced that black is good in all the lines that;s it

It's kind of cute when you hear all these armchair grandmasters like FizzyBand and ThrillerFan dismiss a whole variation played thousands of times at GM level, with only one move, namely c5. Well, even after 3.c5 there is a game of chess to be played.

well I mean in pretty much all openings black is able to equalize, unless it's the Catalan lmao

ThrillerFan's "nothing" is this one:

...which is a bit more than nothing: Black has to work on this to get full equality.

I never said it is refuted.  If White has zero advantage by move 3, he has nothing!  There is a difference between "Nothing" and "Busted".

The French Tarrasch is Nothing for White.  The 1.e4/2.Ke2 is refuted.

Got it?

Black is also completely equal after 1.e4 e6 2.d4 d5 3.Nd2 c5 4.exd5 (4.Ngf3 Nc6) exd5 5.Ngf3 Nc6 6.Bb5 Qe7+.

7.Qe2 Qxe2+ 8.Bxe2?! =/+

7.Qe2 Qxe2+ 8.Kxe2 a6 =

7.Be2 Qc7 8.O-O Nf6 9.dxc5 =

7.Be2 Qc7 8.O-O Nf6 9.Re1 =

Well of course the Tarrasch isn't refuted nothing means no advantage/no serious chance for an advantage Sure White can win with the Tarrasch but it's just like White winning with the Canal Attack- Sure it happens but it's not because of the opening

Just because you get nothing from the opening doesn't mean you can't win as white it just means that it's less likely and you can't really "force" black to hold the draw

Korchnoi played the black side of the Tarrasch numerous times in his matches against Karpov.   He always played 3...c5.  As far as I remember Karpov didn't win a single game. 

Can we say 1.e4?!  then... What does white have against say the Marshall attack?

I think most Tarrasch setups are very easy to play, all except the Botvinnik System, which occurs after the Nf6 Closed Variation, and b6!? instead of Nc6, the normal continuation. Black wants to attack on the queenside and get counterplay while you try to kill the black king on the kingside. I just lost an OTB game due to this system against some 1900 so I recommend you study this. It's rare, but if faced with it, if you don't know the theory, you kinda ded. (aka me)

About the OP statement on 3...c5!? I think it's actually much easier to play as white in the open variation, no matter whether your opponent goes for 4...Qxd5 or 4...exd5.

If they don't take the pawn back after 4. exd5, just develop your pieces and don't worry about anything else. You don't have to try to keep the pawn, instead take advantage of this tempo (the tempo your opponent will use to recapture your pawn) and just keep developing, castle, and have a safe and solid game. Here's an example of something that might happen.

You don't need to take the pawn on e6 because that will slow down your development. Engine doesn't agree with me, but as a human, I think better safe than sorry. Obviously we cannot play perfect moves so even if the final minimax outcome is better for us, it is not guaranteed we can achieve that outcome, maybe our position would be better off had we declined the pawn sacrifice.

I won my one and only game with the Qxd5 variation due to a likely misclick from black. (10 min game) I knew zero theory.

I've been playing this against the tarrasch the last few weeks and I don't think I've lost a game yet. I am waiting for other shoe to drop though. Someone will come along soon and show me just how weak my king is. 

 This used to be a decent line for White before, because Black most of the time went 11..Qd7, when 12.f3 Nd6, 13 Nc5 Qc8 14.Nd3 0-0, 15. Re1, with b3 available, and here Black's knights are deprived of both c4 and e4 squares which is an important part of Black's counterplay in this line. Unofrtunately, Black has a very important resource:11..Nd6! Luckily there are a lot of other setups White can choose from. The one I like is the one with 10.Re1 0-0, 11.Nf1 intending Be3-d4 and Ne3 putting pressure on the d5 pawn.
