So far we have four votes for a4 (Timelord2067, actmyname, languagehasmeaning, and Taras) and two votes for Rfd1 (abacus and myself). There is also one vote for Rac4 (jjacob), but that is not a legal move. We will wait until everyone's done debating a4 vs. Rfd1 and for jjacob to correct his vote before deciding.
We are 3-3 until now, languagehasmeaning switched to Rfd1.
I would like to change my vote from a4 to Rfd1. It sounds like you agree with me that a4 does not accomplish much if black just responds with Qb6
