Kibitzer's Corner
Jun-04-04  PinkPanther: Ouch, not looking too good for white in this variation.
Jun-27-05  12929011: In my MCO 14th edition, 6...e5 is given an exclamation point, but it doesn't explain why it is such a good move. It just doesn't seem apparent to me why black does so well here. Could someone explain please?
Sep-03-05  lopium: All depend of all.
Apr-25-06  sewun77: i was enter my card number , and still can not proccess. exactly what must i do now
Apr-13-10  rapidcitychess: <12929011> I think it is due to the sidelining of the knight on b3. My book says white has a large advantage<Winning chess openings> but this turned about to be wrong about the Sicilian, and French.
Apr-13-10  CruyffTurn: 7.Nb3 just leads to an equal game. 7.Nf3 planning h3, Re1, b3, Bb2 is slightly more testing, but Black is still fine.
Sep-07-11  Robert Hill: Yes, in all my games playing Nf3, I do a lot better.
