The following information is from Dan Heisman. Dan will be giving a FREE seminar on April 6, 2010.
On Apr 6, I will be giving a seminar at ~9:30 at the Main Line Chess Club in Gladwyne (www.mainlinechess.com) about how I discovered that 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.d4 (The Lolli, as opposed to the Fried Liver 6.Nxf7; the Fried Liver was previously thought to be weaker) is not as good as previously thought, which led GM Larry Kaufman and I to conclude that 5…Nxd5 is probably as good as any other recommended 5th move: 5…Na5, 5…b5, and 5…Nd4. This discovery has subsequently been published in New In Chess Yearbook #94, recently available, on page 25. This seminar is open to everyone and is free. Please spread the word if you think you know someone who might be interested.
