New heads up poker game - best strategy?

[tmcdmck]

he could push pre anything and would probably be +ev. he could push any 8 out + draw and be +EV vs an overpair even if called with nothing in the pot. When he actually has a hand he has some serious power. and his bluffs become super effective. wow i would definitely choose to be him rather than you. did he have to call for half the amount you bet aswell by the way?
