When I have a pair of queens (QQ) in hand, I usually find it advantageous to consider an aggressive move and go all-in. Pair QQ is a powerful hand and is often one of the best starting hands I can have. Going all-in has its advantages, as it puts pressure on my opponents and reduces the likelihood of facing a difficult post-flop decision. Also, by going all-in with a pair of QQ, I can make players with weaker hands leave the pot, increasing my chances of winning without needing to see the flop. It's important to consider the context of the game, such as chip stack sizes, player positions, and readings I've taken on my opponents. If I see signs of weakness or if I'm in a situation where an all-in could be profitable, I find it advantageous to use the strength of my QQ pair to try to accumulate significant chips and build a solid stack.
