Jun-06-05  cuendillar: I've been experimenting with the highly unorthodox 1.c3!?, which may give up the first move advantage but works fine anyways. My most original plan is 1.c3 e5 2.c4 entering a reversed sicilian. Now you can play it as white too!
Jul-25-05  azaris: Here's a little gambit for those blitz games.

1. g3 d5 2. Nc3 d4 3. Na4!? Qd5 (she takes the bait) 4. Nf3 b5 5. Bb2! and now:

I) 5...c6 6. c4 Qxc4 7. b3 Qb4
II) 5...Nc6 6. O-O Bb7 7. c4 Qxc4 8. b3
III) 5...e5 6. c4 bxc4 7. O-O Bb7 8. d3

White is ahead in development and wins more time harassing Black's queen.

Jul-25-05  Pawsome: <azris> 5. Bg2 was intended, no?
Jul-25-05  azaris: Yes of course.
Aug-02-05  Marharepa: I played with my father 1.a4 a5 and I won! :D

An extremely irregular, but symmetric opening.

Aug-02-05  SEMENELIN: Unorthodox opening has an interesting results in the entire game. Thats whats making A00 a dangerous line for beginners. Usually its really best for beginners to study such openings. :). I think applying an irregular opening to high rated players could just result to a drawish endgame. Specially if a high rated player knows all the theories its hard to use a A00 cause its risky!
Aug-02-05  ranchogrande: about two weeks time I saw a game between two norwegian GM´s(!!):1.e4-c5.2.a3-g6.3.h4-h5. Poor Tarrasch and Nimzo would rotate in their graves if they saw this.
Aug-02-05  jcmoral: <ranchogrande> Maybe they were just trying to mess with the kibitzers. ;)
Aug-24-05  ThreeE: I wish chessgames would break A00 and some of the other openings down farther. Sure, most of these openings are oddities, but you can learn a lot from these -- how to exploit the weak openings. For example, I'd like to see a discussion focused on 1.Nc3.

  Eric Schiller: I have broken down the A00 stuff in my Unorthodox Chess Openings, and extensive excerpt is online at http://www.ericschiller.com/pdf/Uno..., if you are interested. All the openings are broken out in the Caxton Named Openings project and <chessgames> is working on implementing them here. Names are much better than codes!
Aug-25-05  azaris: <1.e4-c5.2.a3-g6.3.h4-h5. Poor Tarrasch and Nimzo would rotate in their graves if they saw this.>

Why? <1.e4> controls the center and prepares to develop the KB. <1...c5> discourages d2-d4 and allows Nc6 without blocking the c-pawn. <2. a3> prepares b2-b4, contesting the pawn on c5. <2...g6> discourages b2-b4 by threatening to play Bb7. <3. h4> attacks the king position loosened by the push g7-g6 by threatening to play h4-h5, and <3...h5> stops that plan. All perfectly sound and logical opening play, if not a bit modern.

See: Sicilian (B20)

Aug-31-05  ThreeE: Thanks Eric -- I do enjoy your other books. Are you affiliated with this site? Would be nice if this site had some agreed on analysis for each opening.
Sep-25-05  Averageguy: Here is an interesting game I played three weeks ago against Little Chess Partner. It was a Grob opening and I was black: 1.g4 d5 2.g5 e5 3.Bg2 Nc6 4.Nc3 Be6 5.d3 Bc5 6.Nf3 f6 7.0-0 Qd7 8.Be3 Bd6 9.Nb5 Be7 10.Re1 a6 11.gxf6 gxf6 12.Na3 0-0-0 13.c3 f5 14.d4 f4 15.Bd2 e4 16.Ne5 Nxe5 17.dxe5 Nh6 18.Bxf4 Rdg8 19.Nc2 Bh3 20.Ne3 Bxg2 21.Nxg2 Qh3 22.Bg3 Rxg3 23.hxg3 Ng4 24.e3 Rf8 25.Qc2 Qh2+ 26. Kf1 Qh1+ 27.Ke2 Rxf2+ 28.Kd1 Qxe1+ 29.Nxe1 Nxe3+ 30.Kc1 Nxc2 31.Nxc2 Bg5+ 32.Kd1 Rd2+ 33.Resigns
Nov-18-05  melianis: Opening of today is the Van Geet opening 1.Nc3, which blocks the c-pawn and makes it difficult to efficiently develop the QB. Black may quite easily transpose to Sicilian, Caro-Kann or French. If I played this, I'd go for Vienna, or inverted Dutch, with an early f4, or try something really obscure like 2.a4, 2.h3 and see what comes out of it, or if 1...c5 then 2. a3. One interesting line could be 1.Nc3 c5 2.d4 cxd4 3.Qxd4..., with a Scandinavian like queen without the retreat to c2. Blocking the c-pawn is IMO outright silly, since English systems with 1.c5 and 2.Nc3 are available. Slipped there to pathos, sorry, advocates of this opening.
Dec-06-05  garfi: i really love polish opening. I got 1576 rated from that opening
Dec-06-05  refutor: polish is garbage ;) 1.b4 c6 2.Bb2 a5! wins for sure...the old outflank variation

<melianis> in the van geet after 1.Nc3 d5 what would you play? i don't like 2.d4 and if 2.f4 (for instance) isn't 2. ...d4 looks decent as in Fine vs A J Fink, 1932

Dec-08-05  melianis: <refutor> After about 15 mins of not very serious investigation (avoiding the main lines 2.d4 and 2.e4) it seems to me that in one line, e3, f4 and Nf3 could work (though black has many options). Another try could be 2.e3 and 3.a3 or 3.a4 trying to setup a French Winawer-, or-what-ever-, like position for white. I don't know if there's any benefits to the 'extra move' in this case. Still one more line could be 1.Nc3 d5 2.f3 d4 3.Ne4 e5 4.c3 ... resulting in a very congested position, which may be strong enough for a decent game. Or did you ask suggestions for black?? I did look at the game you mentioned, but did not even try to go into details. Fine played (once more) a fine game.

Dec-09-05  Ivan23: What's the Meadow trap in 1. a4 e5 2. Ra3, maybee I can try it in correspondence :)

  keypusher: I seem to be getting outplayed on the black side of a Polish right now on Gameknot -- I'll post it when it's over. Unfortunately I didn't see <refutor>'s post on the Outflank Defense in time. :-)
Dec-12-05  melianis: <refutor> of course I meant this Opening Explorer as white (with Nc6 to follow), no white winawer accessible here. Maybe this is playable, but i don't like it.
