My refutations of openings (early pawn sacs)

    I'm not going to claim "refute", but I always get an EXCELLENT GAME as Black using the Chicago Defense!  The key is don't develop the Bishop to e7 and allow the 12.Na4 garbage.  Against the "Main Line", Black should play the 7 pawn moves, Nc6, Ra7, Rd7, and either 11...Na5 (my preference) or 11...Bb7.  Both are fine for Black, and it's sheerly a matter of personal taste as to why I prefer 11...Na5.

    I really liked the Chicago defense for black in the Smith-Morra, and I've played it several times in the past.

    But white can play an early Be3, and then Ra7 is not possible.

    Now i'm looking for ways to refute the stonewall dutch

    I think in Euwe's book (The Middlegame 1) shows how to play against the Dutch Stonewall properly without tricks.

    the smith morra gambit is pretty good but not as good as the good old reliable 2. Nf3 according to this paper:

    There is a misunderstanding in this thread as to the chess definition  of  refute.Refute doesn't mean,one's game becomes more difficult,in chess "refute" means one's winning chances are few to none,draws are still very possible but essentially one has no chance of winning.The side playing a refuted line is essentially passing on the oppertunity to win and will struggle for a draw.

    I've never lost to the KID even against a 2435. (who i beat) However, due to the massive complexity of the main line, I will be wrong

     in some cases.

    It seems that even the great ajian can lost when playing against the KID

    so far my refutation of the blackmar diemer has went through and my wing gambit one works. you guys are making it hard for me in terms of from and danish

    Your 'refutation' of the blackmar diemer is so hilariously deficient I'm guessing no one felt the need to address it. No one would play 6.Bc4 after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nc3 Bg4. Just so you know, 6.h3 is almost certainly White's best move in that position. That leads to the Teichmann defense, which has been mapped out pretty thoroughly and after 6...Bxf3 7.Qxf3 c6 8.g4, there's probably no advantage for Black there, but there are plenty chances for Black to mess up horribly in its hapless quest for an endgame with an extra pawn.



    The most challenging systems against the BDG, both from a theoretical standpoint and a practical standpoint are the Lembergher defense (3...e5) and the O'Kelly/Ziegler defense (4...c6), and I anticipate the more dogmatic advocates of those systems will have some strong things to say about this opening (and perhaps me, for even playing it) quite soon. It's unclear if Black can concretely refute the gambit in those lines, but I think Black can definitely equalize by force a few ways and there is the potential for some lines to lead to =/+ endgames. I can't leave my engine running days on end for every move in every variation, to be sure of it.

    I would play 6.Bc4 

    Develops a piece to an agressive square, prepare's castling, and is sound positionally, so why is it bad.

    Like the sicilian dragon, the scandinavian, the caro-kann 4...Nd7 variation and the Grunfeld defence. (the latter will also be very difficult so I will use the fianchetto variation) @vishal kobla

    You'll never be able to do it becaues I play it!
