For me there's many things to consider before folding or when playing QQ. Chip size, what position, read on the opponent etc. One example where I would fold QQ is if my opponent is a tight/cautious player with average stack and re raise me pre flop, I would fold. Another example is if flop has an A or K and my opponent shoves after my c-bet I would fold. I play QQ aggressive more against loose players and fold more to tight players. If I can't get a read on someone like if I just joined a table, I try to limp in to see the flop. Reason is I don't know how that person plays, they could be limping in the pot too with AA, trying to slow play AA. I've seen this happened many times. Also if I'm in position and have a good read at the table, will shove all in on low chip count if there's a few limpers. I hope this helps, btw if you need better advise next time your question should be "how to play QQ"
