KQ and AJ

These hands are causing me some headaches at the moment, I'm happy raising them in the last 2 or 3 seats with no raises in front of me. However in middle position i find myself wanting to call rather than raise with them. I don't know if this is just me being weak and passive or not. In the first 2 seats i also get torn between folding and calling. Most of the time a raise will come in behind me and i'm not calling a raise in EP with these hands so folding seems sensible but these are pretty good hands and throwing them away seems a bit weak as well.

Over my past 10k at full ring 50/100 NL i'm running at 15/3.5
3.5% pfr seems rather low, i used to run at about 7% but i've had an 18 month gap and i'm trying to get back into the groove. I'm winning at a fairly mediocre 1.9 BB/100 so there's plenty of work to be done on my game.

So how do you guys play these hands, especially in middle positions?

id raise, but then my mp range is quite wide meaning id have 78s and T9s here some times and AJ/KQ also.

Yeah, 3.5% pfr is really low. I open raise KQ & AJ from all positions and raise them behind limpers (but my FR pfr is 14%). If they're suited I'll usually call raises with them (occasionally re-raise), if offsuit I'm almost never calling raises, except from loose pfr'ers.

Since you're obv a bit more conservative, I'd recommend dumping them offsuit in EP, open-raising in MP and later, and always raising both from LP. If they're suited you could open limp or limp behind limpers in EP & MP, and still always raise in LP.
