Let's walk it through.
A new player comes to the table from the big game (2/5 NLHE earlier, then 1/2 PLO). On his first hand, he straddles, player to his left raises to 10, one caller, you have QQ, raise to 40, and it folds around. On the next hand, 4 limpers to you, you have QQ again, raise to 22, and end up HU with the new guy, who dark checks to you and the flop comes AdJd7d. What do you do and why? (btw, you don't know if you have the Qd, but don't think so and don't want to look for the time being)
