Only raising AA,AK,AK or KK is being way to nitty. You should be raising more with your position then the strength of your hand. The later position the less dependent on good cards.
This article should help.
Id call instead of raising if im in position, and against someone who is raising too much. If he's been raising alot and i think my hand does good against his range. If i hit ill most likely be ahead and if i dont, i still have position.
You have to 3-bet shove with 20-bb imo.
Which is why id rather call in this situation.
Id also raise to 2.5bbs from late position alot of the time.
