blitzing on third and long and the problem with poker forum advice

[Silent A]

I think I may be one of the regular posters here whose posts may fit your above description. However, I always assume when we say "the best play is _____" we're talking about the standard play around which we build a mixed strategy.

That said, there is a near complete lack of explicit mixed strategy discussion here. It usually only pops up (indirectly) when different posters suggest different, but individually reasonable, lines.
