Yes you should be looking for options to stack the other big stack. Preflop matters less, because the implied odds are more.

Think about it as this:
Both players have 1000000000000 stacks. BB is 1. You can call any standard preflop bet with any hole cards you get.

Especially play big pot cards; Axs, connectors, 1 and gappers.
And you can start 3-betting a lot more preflop. Preflop betting sets the betting amount postflop. When stacks are deep, you can play bigger postflop...and you have to, to win villains big stack.

There's a lot more to deep stack playing what I don't know, but others will......but there are the basics.
