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.
It also looks like our esteemed opponent does not wish to confirm or deny that he is Bruzón Batista. I figured I was right.
I prefer not to confirm or deny every guess or I may reveal myself quickly. However I can deny in this case since I already provided a clue that eliminated him as a possibility (based on current ratings):
