Those were just overall stats, but it's basically the same if unopened in MP.
I don't like being oop, so I keep a fairly tight range until I'm later. I'd much rather 3bet 7:club:6:club: from the CO or button than raise with it in MP. I'd also definitely prefer raising 7:club:6:club: in MP over K:heart:Q:club: or A:diamond:T:spade:. Of course table dynamics vary and sometimes I'd be pumped to put money in with those hands, but on average no.
As far as broadways, I'm folding tons of them in MP. Lot of people I'm playing with are going to be real hard to deal with postflop when they have position. Also their range basically consists or either hands that dominate weak broadway hands, or that will put me in a RIO spot. Once that happens, I'm winning small pots and losing the bigger ones, so I just pass on the spot altogether.
