I suspect deep stack play is heavily dependent on your playing environment and as BQ features posters who play all over the place, you might get heavily variable advice here.
I play 25nlz, so my advice is based on that.
Reg V Reg or Reg V Unknown eff stack > 200bb, oop 3bet bluffing is simply spew, you'll get called preflop and floated flop everytime. So oop 3bets will be linear and strong. IP you can balance a little bit with good speccy hands, but just be aware you going to get called waaaayyyy more whatever you do.
4bets and more deep are basically AA v KK, so don't be the guy who stacks off preflop 200bb with KK.
One thing above all else...deep stack play, you want
position its a huge factor. So preflop you really got to think it through before you get into the pot.
Post flop deep stack play is a book all by itself. A one line piece of advice I've seen dozens of times is:
"In a deep stack pot, don't build a big pot out of position" (unless you know you are way ahead and staying way ahead).
Finally deep stack spots are uncommon, so I wouldn't worry about individual reads/stats on your deep stack preflop ranges - stat convergence factors would mean villain would need thousands and thousands of hands on you to draw any conclusions.
Good regs that understand deep stack play, will know what's going on. Poor regs will just look at your raw 3bet stat and apply that.
Being IP against a poor reg in a deep stack spot is thing of great beauty
Unfortunately it does not happen often enough
