{History of the Dory(Doery)Defence}
^Ladislau Döry von Jobbahaza (born in Austria, 1897)- Author of the "Döry Defense" (or "Doery Defense", of course) <1.d4 Nf6  2.Nf3 Ne4>

^He was sentenced to death by the Nazis but it's not clear if he survived the war or not.

^However, the entry on “Döry Defence” in The Oxford Companion to Chess (page 112 of the 1992 edition) states:

“... pioneered by Ladislaus Döry, an Austrian Baron, in 1923 … In 1943 Döry was sentenced to death by the Nazis for sedition, but was released from prison by Allied troops in 1945.”

^The May 1937 Wiener Schachzeitung carried a report on the Döry Defence tournament, held in the Café Central, Vienna on 19-26 May. Keres, Weil, Becker and Podhorzer (order of finish) played two games against each other. From the many games from the event which the Wiener Schachzeitung published, we pick the following:

Now some other games in the Dory.
















^I have to admit that the idea of moving the knight twice is a bit bizarre:
Natalia Zhukova-Antoaneta Stefanova, European Junior Championship Rimavska Sobota 19921 d4 Nf6 2 Nf3 Ne4I like this move which is designed to shock White into making an error. Apparently the Austrian Ladislaus Dory pioneered it in 1923. 3 c4 I noticed that in Vienna, 1937 there was a theme tournament that explored this line and was won by the famous player Paul Keres. It seems to have contributed a lot of the games bolstering the line and I hope some enterprising player will start employing it again on a regular basis. a) 3 Nbd2 d5 4 g3 c5 5 dxc5 Nxc5 6 Bg2 Nc6 7 0–0 e5 Black creates a pawn centre so White will try to undermine it 8 c4 d4 9 b4 Nd7 10 b5 Na5 11 Ne1 Be7 led to equal chances in D.Podhorzer-P.Keres, Vienna 1937. b) 3 Nfd2 d5 4 Nxe4 dxe4 5 Nc3 Bf5 6 g4!? (6 g3 is the safe reply aiming for a kingside fianchetto followed by castling kingside) 6…Bxg4 7 Bg2 f5 8 Bf4 e6 9 f3 exf3 10 exf3 Bh5 11 Nb5 (11 Qe2! puts pressure on the weak e6-square and threatens d4-d5 promising White the slightly better chances) 11…Bd6 12 Nxd6+ cxd6 13 Qe2 Bf7 14 Rg1? (14 0–0–0 leads to a double-edged position with sufficient compensation for the pawn) 14…Qh4+ 15 Bg3 Qxd4 Black wins another pawn and just as importantly prevents White from castling queenside. 16 Bf2 Qxb2 17 Qc4 Qxa1+ 18 Kd2 Qf6 0–1, A.Becker-D.Podhorzer, Vienna 1937. 3…e6 Or 3…d5 4 Nc3 Nxc3 5 bxc3 e6 6 g3 (even though Black has played a wacky knight move the position is level) 6…c5 7 cxd5 Qxd5 8 Bg2 cxd4 9 cxd4 Bb4+ 10 Bd2 Bxd2+ 11 Qxd2 Nc6 12 0–0 Qa5 13 Qb2 0–0 14 Rfc1 Rb8? (it is not a good idea to offer an experienced grandmaster a tactical opportunity) 15 Rxc6! 1–0, K.Aseev-B.Bartsch, Neu Isenburg 1992. 4 e3 b6 5 Bd3 Bb7 6 0–0 I suspect White is assuming that this is an unusual position after the shocking second move. In fact, it has now transposed to a fairly respectable opening which usually arises after 1 d4 Nf6 2 Nf3 e6 3 e3 b6 4 c4 Bb7 5 Bd3 Ne4 6 0–0. 6…Be7 The alternative 6… f5 to support the knight is a well know idea in the Nimzo-Indian and has proved successful for grandmaster Sax: 7 Nbd2 Bd6 8 Qc2 Also possible: a) 8 Ne5 Bxe5 9 dxe5 Nc5 10 Be2 Nc6 11 f4 Qe7 this is the merit of not castling early because now Black has the option of safely putting his king on the queenside in order to attack freely on the kingside 12 Bh5+ g6 13 Bf3 a5 14 Nb1 0–0–0 15 Nc3 g5 16 Nb5 g4 17 Be2 Ne4 18 a3 Rdg8 19 Bd3 g3 20 Bxe4? (20 h3 Nf2 21 Qe2 Qh4 is good for Black) 20…gxh2+ 21 Kxh2 Qh4+ 22 Kg1 fxe4 23 Rf2 Rg6 24 b3 Rhg8 25 Raa2 Rg3 0–1, T.Straeter-G.Sax, Senden 1998. b) 8 Qc2 Nxd2 9 Nxd2 Qg5 (it is always good to threaten
Opening Lanesmate) 10 d5 Na6 11 a3 Nc5 12 Be2 exd5 13 Bf3 Qh6 (if at first you don’t succeed threaten mate again) 14 g3 Qe6 15 cxd5 Bxd5 16 Bxd5 Qxd5 (the point of the black queen’s manoeuvres are revealed because he won a pawn and managed to make White compromise his kingside pawn structure) 17 Rd1 0–0 18 Nc4 Qf3 19 Nxd6 cxd6 20 b4?! (it can hardly be wise to encourage Black to bring another piece into the attack) 20…Ne4 21 Bb2 Rac8 (Black wishes to stop the white queen from defending the f2-pawn) 22 Qb3+ Rf7 23 Rf1 Ng5 24 h4 Nh3+ 25 Kh2 Nxf2 26 Rad1 f4! 27 Rg1 (there is no escape from the crisis because 27 gxf4 Qh3+ 28 Kg1 Qg3 mate or 27 exf4 Qxb3 wins) 27…Nxd1 0–1, M.Scekic-G.Sax, Athens 1999. 7 Qc2 f5 8 Nfd2 Nd6 9 e4 It is better to bring the rest of the pieces into the game before advancing the e-pawn so 9 Nc3 deserves consideration. 9…Nc6 10 e5 Nxd4 11 Qc3A quick glance indicates that Black must lose a knight and I suspect that White was happily awaiting resignation. 11…Ne4! An excellent idea which refutes White’s tactical scheme. 12 Nxe4 12 Qxd4 allows 12…Bc5 trapping the white queen. 12…fxe4 13 Qxd4 Bc5 14 Qc3 exd3 15 Qxd3 Qh4 Black has excellent practical chances because the pair of bishops are aimed at the white king which is a sure sign that an attack is imminent. 16 Nd2 16 Be3 to reduce the effectiveness of the bishop on c5 is the best defence. 16…0–0 A simple but effective move that heaps the pressure upon the f2-pawn. 17 Qg3 Or 17 Qe2 is met by 17…Rf5! when 18 Nb3 Bf3! 19 gxf3 Rh5 leads to mate. 17…Qxg3 18 hxg3 Rxf2 19 Rxf2 Rf8 The pin on the rook means that Black will have a material advantage. 20 Nf3 Bxf3 21 Bf4 Be2 22 Re1 Bxf2+ 23 Kxf2 Bxc4Now Black is two pawns up and has a winning advantage. There are plenty of players who might still think of a draw due to the opposite-coloured bishops, but because the rooks are on the board it is of little help. 24 Ke3 Bd5 25 Rd1 h5 26 b3 Rf5 27 Kd4 Bxg2 28 Re1 Bd5 29 Re2 h4 A nice nuance to create a passed pawn. 30 Rh2 Of course 30 gxh4 allows 30…Rxf4+. 30…g5 31 Be3 hxg3 32 Rh3 g2 33 Rg3 c5+ 34 Kd3 Kh7 35 Bxg5 Rf3+ 36 Rxf3 g1Q 0–1
