  Joshka: Danny ( in a repeat interview on speaks about a Tal-Larsen game Alekhine's Defense, where Tal could have a Nxf7 move. Checked the database here, do not believe it's the one that is listed, am I mistaken?
Premium Chessgames Member
  AgentRgent: I believe it may be this one: Tal vs Larsen, 1965
May-03-05  Ziggurat: <AgentRgent> beat me to it! That's the game.

<If this had been in a simultaneous display, I would have decided that my opponent had simply overlooked the stroke 6. Nxf7 Kxf7 7. Qh5+, when, against his will, the black king is forced to 'go for a walk'. But Larsen could not have missed this, and I began examining the possible variations, which were, of course, pretty complicated.> - Tal

  Joshka: <agentRgent> <Ziggurat> Allright thanks a lot, this is a very interesting line.
Premium Chessgames Member
  Joshka: What are the moves for the "Kopec" system?....I believe there is a Bd3 somewhere in the opening?
Jun-14-05  pyryk: <Joshka> Check mr. Kopec's first game in this list, D Kopec vs K Spraggett, 1976. White's moves include, among others, e4, Nf3, Bd3, c3, Bc2.
Premium Chessgames Member
  Joshka: <Pyryk> Allright thanks!..this system is almost like playing the white side of a Ruy against the Sicilian, without Bb5.
Jun-16-05  hongisto24: not a fun system- if you like to attack.
Oct-31-05  DP12: It's Dr. Kopec.
May-24-06  Maynard5: Danny is currently a professor of computer science at Brooklyn College in New York, and has authored or co-authored several impressive articles on artificial intelligence.
Feb-05-07  fighter92: Danny Kopec has written a chess book "Mastering the Sicilian".
Jan-31-08  pazzed paun: anybody attended one Kopec's chess camps?
Jan-31-08  Strongest Force: In-between rounds, heading towards an eventual first place, remembering me from junior days, Danny challenge me to some blitz-chess; i declined and gave him Maxim Dlugy instead; NYC is strange.
