"Yes, of course, but it doesn't seem as if RIGHT NOW more tix are being released for this particular show. (What I meant, anyway.) Since the show doesn't start previews for a few more weeks (right?) there is nothing the OP can look at right now."
OP was looking for tricks to get tix (not necessarily "RIGHT NOW"), and mentioned that s/he had gotten tix for BoM 1 week ahead of time and observed that "shows [seem to] always block seats and then slowly release seats closer to the date."
I was merely confirming that his/her observation was accurate (house seats are most definitely being held back), and gave them a time frame in which to look for them to be released, if they are not used.
