Question about raise-size (w/HH)

[emm]

SB and BB are ok players. There aren't really any draws on this board, and Im going to safely assume that a checkraise from one of them has KJ beaten. I can also safely assume that they arent tricky FPS players who will make a play with a marginal hand.


I know I have the donker crushed here. What should my raise size be here?
