When do I raise my QQ on a ultra-loose table?

[Sqwrlking]

QQ is the third best starting hand. It does play well multiway, so raise it up. You aren't doing it to thin the field, you are raising because you have a huge equity advantage. Raise for value.

Bet the flop. People with anything will call regardless, you can't drive them out. Raise for value and to not give a free card. You almost certainly have the best hand, and you have backdoor straight and flushdraws. Bet for value.

You have to play a premium hand like QQ aggressivly. You'll probably win less often if you raise preflop, since a lot of people will call more often in a big pot than in a small. But the pot will be so much bigger it'll easily offset the times you lose because you bloated the pot.
