My first experience came from 200K hands at $5 & $10NL FR... where 
tight is not only right, it's essential. You'll get creamed at those levels playing 
loose against nut campers -- winning lottsa blinds and small pots but getting stacked far too often in the process.
Went to 6max and am running 6+BB/100 over 15K hands to date. Yes, can loosen up IF and WHEN your 
post-
flop skills (hand reading, 
pot control, positional 
aggression) 
catch up with your pre-
flop skills. Remember that playing 2nd and 3rd tier hands, even 
in position, give you a much weaker foundation to start you 
post-
flop plan from -- and therefore make for much more difficult decisions.
15K hands isn't sh!t -- but I'
m recognizing a pattern at these levels. 
Steal blinds, poke aggressively and then 
back off when appropriate, take down small pots opportunistically (usually 
in position) keeps me 
ahead of the blinds and maybe contributes a BB/100 or two... The money is coming from the 
monster hand 
stack-offs -- and most of those are coming from big flopped hands... 
QQ+ over pairs, 
AA-
KK PF 
stack-offs, and flopped sets from mid+ pocket pairs.
Took me about 80K hands to learn that taking people's stacks with monsters every 3-400 hands 
don't mean sh!t if I proceed to give it all 
back over the hands in between by p!ssing it away at the margins. But I'
m a little dense....
