Hi and welcome-

I'll say first of all that I have not yet managed to win at 1/2 yet but that said:

I would raise preflop.
I would 3 bet on the flop.
I would lead the turn.
I would lead the river.

As it played out, sounds/looks like you lost to an 8, but it shouldn't change the way you play the hand on the flop and turn. Assuming he has an 8 in his hand, theres just as much chance that the river is a Q as an 8.
