Early Tourney Hand

This is on the first rotation of the tourney so I don't have any reads on the players. CO got his chips when he took out a player who was down to about t500 with TT against KQ, preflop. The BB took about t450 off CO when he called AK from EP, called a raise to 3xBB and then called CO down on a flop of KJJ and CO had TT again.

Anybody like to reraise preflop? Does anyone lead out here on the flop? What line do people like here considering how I played it? What is your plan on future streets?
