I like Dean's line. I don't know if villain is on the NFD or if he has a set, so combined there are 17 scare cards on the turn. I would probably raise just a little less to give my opponent the illusion that I am not pot committed in case he wants to push the NFD or QQ/99. Aggro villains love to semi-bluff here with an A of diamonds; make sure you give them the opportunity. And QQ/99/22 will have a very hard time folding; don't make their decision easier for them by overbetting the pot.

Fnord's line may be higher EV, but will leave you with some really tough decisions on the turn 1/3 of the time. I'm lost on the turn with any diamond, 2, 9, or Q, so I prefer to pot commit myself now. So I vote zomg don't suckout on me, but don't blow them out of the pot either.
