KK from SB - Better Line?

[bnorthro]

I just played this hand and I'm wondering what a better line would have been. When you catch a monster from the Blinds, so your'e out of position for the rest of the hand, it seems checking is going to be kind of suspicious, and I'd really hate to get checked through. Would you play this differently? Villians are all pretty loose/passive, BB was 64/7, UTG was 35/0.

A check raise probably would have been good somewhere, but against passive opponents, I thought it may get checked through. Anyone?

Thanks.
