Secrets of Opening Surprises

Sep-27-04    siggemannen: what does this Doubly Deffered means? Sep-27-04    refutor: doubly deferred, he had the option at Opening Explorer and Opening Explorer Sep-27-04    sneaky pete: <siggemannen> 4.Bxc6 .. is the exchange variation. If white delays the exchange one move and plays 5.Bxc6 .. it's the Bayreuther variation, named after Alekhine vs Bogoljubov, 1934, 16th matchgame played in Bayreuth. If white only exchanges at move 6 it's called Deferred Exchange Ruy Lopez Delayed or Steenwijker variation, after Euwe vs H Kramer, 1940, played in Steenwijk. Sep-28-04    siggemannen: thx <refutor><sneaky pete>. I've always wondered if it was some special meaning in those words, but now i know. anyway, is this opening sound in high quality chess? Mar-01-05    Abaduba: What about the DERLD part? What does that mean? it's not like they needed to make the name longer. (= Apr-24-05    crankydoodle: so the logic of this opening is to "fake" your opponent into castling kingside, whereas in the regular exchange black does ...Qd6 (in general) and goes for a queenside castle, right? Apr-25-05    Dick Brain: <crankydoodle> A big difference is that the regular exchange variation variation usually results in an endgame, often very similar to the one seen in the Berlin Defense. The DERLD usually remains a middle game, although it's probably even more drawish than the regular exchange. May-23-05    crankydoodle: k thankz Sep-07-05    aw1988: Is this quite possibly the funniest name for a chess opening ever? Sep-07-05    Resignation Trap: <aw1988> Obviously you are unaware of the Double DIRPs Defense: 1.e4 Nh6 2.d4 Na6 3.Bxa6 bax6 4.Bxh6 gxh6. "DIRP" is an acronym for "Doubled, Isolated Rook Pawns". Sep-07-05    aw1988: Uh. Heh. Apr-02-06    blingice: Thinking back to the Chessmaster tutorials I watched last night by Josh Waitzkin, he said to "capture towards the center". With that rule, the b pawn should capture the bishop, not the d pawn. Why should the d pawn take here? Is it simply the variation with no logic other than that no one has tried to challenge it with off-book ways? Apr-02-06    ganstaman: I think it comes down to pawn structure. Capturing with the b-pawn isolates the a-pawn, which isn't so good for an endgame. Capturing with the d-pawn creates a solid queenside pawn mass, with the doubled c-pawns not being too much of a weakness. Also, it's important to know why the general rule is to capture towards the center. This is because doing so increases your control of the center (this is why a c-pawn is slightly more valuable than a b-pawn, therefore ...bxc6 is somewhat of a promotion in general). Without actually knowing much about this variation, I'd imagine that the half-open d-file allows the black queen some center control, and ...dxc6 also allows the light square bishop to develop to better squares. You should also look at this variation of the Scotch: 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4 Nf6 5. Nxc6 bxc6 6. e5 Qe7 7. Qe2 Nd5 8. c4 Ba6 (I think I got all the moves right...). Here, 5...bxc6 is preferable to 5...dxc6. From what I've found playing this and similar variations, black's light square bishop works best on a6 (as seen here). In other variations without 6. e5, having played 5...bxc6 allows an eventual ...d5. The most important thing to know about a rule is when to break it. Apr-02-06    aktajha: It's actually important to take it with the d-pawn; to protect your pawn at e5. After nxe5 you know have the fork Qd4. If you would've taken with the b-pawn, you'd have lost a pawn for nothing. Apr-02-06    who: 7.Nxe5 Nxe4 Apr-02-06    blingice: Another question: The line for this opening says it ends after 6. Bxc6, but the diagram shows after 6..dxc6. Which is correct? I'd expect it is truly a C85 after 6..dxc6.
