I am wondering what people mean by 'open up' preflop.
My stats are very similar to Martin's and we both play the same site and stakes.
It is a very fishy site (PokerRoom skins) and there are a ton of calling stations. I prefer not to piss money away to these people postflop with mediocre holdings so I value bet all the way and make decent money that way.

However, in my session review it was suggested that I throw away too many reasonable hands that could at least be limped in early to mid position. KQo, ATo, QJo, JTo, suited connectors and the like. I just dump this stuff most of the time (on non-limpy tables) in EP cuz I'm folding it to a raise (mostly) anyway. And if it's a 3-way hand I'm not going to make much outta the hand anyway. I'm sure there is some value in 'stealing' postflop with these types of holdings...but most of the time I'll be check-folding the flop so I have previously considered such open-limping to be a waste of a quarter

Is this type of limping in any way what people mean by loosening up? What about in late middle position or HJ-Button if there are no limpers? I would definitely open raise KQo, ATo in the HJ or beyond...but I don't tend to open limp most of these hands (maybe KQ) in MP or LP with no limpers before me...at best I would win a tiny blinds-only pot so I don't bother - especially when multi-tabling.

This is FR btw and not 6-max we're talking about - obviously those hands play a little differently at 6max.
