Well there are books written on the subject so I won't go any farther than to say that when you get to deep stack you can really get into playing some REAL small ball poker. So that's where you should focus your energy for 200 BB. You have more bullets so you can afford to do things like fire warning shots (3-bet backoff buddy) without crippling yourself.
Most tournaments guys like us play, though they may start around 100 BB, you really can't (or shouldn't) get into small ball - or at least not for more than a span of time measured in minutes - because the rapid escalation of the blinds puts you at around 50 BB or less really fast.
So it's not just about starting stack size but how fast the blinds escalate forcing you away from small ball becuase it is just no longer feasible to make speculative investments with a shorter stack - it's kind of like a microcosm of bankroll management. Sure you can beat the odds
by doing what you shoudn't do, but in the long run it's a loser.
