Pre-Flop Raises in NLHE

[monkey_love]

How much should I be raising pre-flop in NLHE (specifically, micro-limit)? As a starting point, let's say I raise (3-5 times the BB) with AA-JJ from any position and AKs from late position. I also re-raise with AA or KK.

Typical games seem to have 3-4 limpers with a raise usually getting 1-2 callers.

I'm guessing that this is much too tight but I'm not sure how much I need to expand or how much it is hurting me.

Thanks.
