set heads up... tell me how to play this better!

[stealyourface]

I have been running over the table for an hour or so, LAGing it up. The table has broken up and it is now heads up. My opponent is unremarkable and seems like he has been waiting to take a stand against me.

I have raised like 7 of the last 10 hands preflop.
