I disagree to fold QQ in early position. On the moment that the blinds are bigger, people will be raising more since there is more to win and probably enough ante in the pot already. Also the lowstacks will shove quicker with decent hands like A10 or lower, maybe KQ, KJ, K10. Sometimes J10 suited and lower pocket pairs for example. It can be good to limp in a hand like QQ with a big stack. Theres much likely someone raising or either going all-in. If nobody raises and the flop is scary, with more limpers in the hand and the small and big blind, then u can easily fold to a raise, depends on the flop also of course. Anyway "NEVER FOLD" the QQ in my opinion.
