defending you Big Blind in a 10 or 9 seat full ring game...

I am a proven winner at Longhand and thats what I know how to play...
the big thing for me was to just realize how I should be adapting my
successful play there to be successful at SH...

I also am unsure of how to properly/correctly defend my Big Blind (in both Longhand and SH)...

I am most concerned with my thinking/thought processes/how I should be approaching the SH
games, and wow - it hit me like a ton of bricks when you guys
were saying I should be playing the SH games just the same at I would in the same Late Positions as
I would in the Longhanded games...no different. Not at all. I shouldn't even be trying to
steal with trashy hands myself, because most opponents will have widened defense ranges, so
therefore, in that type game (which is most SH games out there),
I would gain no benefit by trying to steal with "increasingly trashy" hands myself. I should, as said before, simply be attempting steals WITH THE SAME EXACT HANDS THAT I WOULD IN
A LONGHANDED GAME IN THE SAME POSITIONS OF THE HJ, CO, AND BUTTON.
This is profoundly correct thinking in my opinion, thinking in which I had not previously considered...

the 2nd adjustment I should be making (which Ed really points out in his article) is
to defend my BIG BLIND "tenaciously." And to be doing this because my opponents
(in the typical SH game that's out there) have incorrectly widened their steal range, and NOT because the
blinds are posted more often (this fact is irrelevant and should be
thought of as "the price you pay for getting to be in the advantageous late positions of the HJ, CO, and BU more often" as BArron said.
Ed also said that although you post your blinds more often, you have more "equity" in them each time...
(and, although I'm not totally sure here, I believe the REASON FOR THIS
is because of the incorrect play of the typical SH opponent (that causes you to adapt and defend more) and not because you post them
more often...Pls. correct me here if wrong...

I know that doing these 2 things will make me a significant SH winner.
I haven't put these into practice yet, I just know they'll work...

Please correct any of the above if I'm wrong - I wanted to summarize it and type it back to you guys to make sure I understand this properly...before I hit the tables and try it!
(if it works I owe you guys who responded a beer...no...a full dinner! lol)

1 more follow up question about "defending." (which, as I just learned, if your opponents are playing SH correctly and not widening their steal range in the SH game, would be the same as for SH as it is for Longhand...).

Ed mentioned to 3 bet a steal raiser with hands that have "showdown value."
What hands would these be...pretty sure they are:

1.) any pocket pair
2.) any ace
3.) anything else?

And pls. comment on what I said about the 72o...if you KNOW a player is weak post flop, and WILL fold if he misses the flop (if he has an AQ or AK/2 big cards OR if he has 10s and 2 overcards flop, etc....he's a tight wad) AND
you raise him, does it make it correct to ALWAYS take a flop against this guy?
(when he raises your Big Blind and you have not even looked at your cards?)

(once you start doing this, he should catch on and adapt, but we'll assume he wont't and is a tight-wad ABC player who "only plays HIS cards" for the purposes of answering the question...)

Thanks again,
