I'd call the police and barricade my door. Like to see him smash through a door that also has my bed lodged between it and the opposite wall.
From that position I have no chance of defeating him but assuming he is a real assassin I would never have a chance of defeating him, my best chance is to fight him off and delay him till the authorities arrive.
I have an aerosol can and a lighter so if he manages to cut a hole in the door somehow I'll flame his face if he tries to look through and shoot me.
I also have a souvenir from when I lived in Thailand, an elephant hook, basically a steel spike curved at 45 degrees away from a 18 inch long stick, of course it is just an ornament at the moment but if my life was threatened I would do anything to defend myself...
If that doesn't work Plan B is to set my bed on fire and escape out my window where I can actually leap into my neighbour's garden where I would then run, not in a straight line but taking as many turns as possible and not stopping till I'm physically exhausted, then I hide.
