Continuing on from there, then.... I think it is the Qb6 that is the 
bizarre'
move, not necessarily the Bb5.
Why develop the Queen so early... and for what purpose?
 
Well, that is how this particular opening is played. The idea of playing the 
Queen to b6 is the attack on the b pawn. Also the Queen lends support to the 
d4 c5 squares. Also because of the unprotected King the Queen slows castling 
for white. Since the French for black is somewhat cramped it makes sense to 
develop quickly and to slow whites development in the process.
Now that the queen is there white plays Bb5 to shut the line off for the 
queen and pin the knight. BUT it's a bad pin. Right? Unless white plans to 
close the center down in which case trading the knight for a good bishop 
makes sense. 
So many things to consider. Sorry for the typos.
 
Take care.
