Move 9
What's the deal with 9. a3?

The appropriate continuation is 9. Bb3! —The preceding unsigned comment was added by JamesMazur2 (talk • contribs) 20:26, 9 October 2009.
 * For a time ECO gave 9.a3 an '!', reason being white takes central piece and gains initiative. SunCreator (talk) 19:02, 12 October 2009 (UTC)

This needs to be changed. The correct notation is 8...Nb4, not Ncb4. There's only one Knight that can move to b4. —The preceding unsigned comment was added by 76.74.203.112 (talk • contribs) 02:17, 6 July 2010.
