I would say that tactic is a way to compute the situation, and strategy 
is going beyound this.
Basicly, for me the tactic is all you can solve by just reading, and 
strategy what you use when you can't. For exemple, a small strategy 
could be to consider that, if we don't know if a worm is alive, we 
consider it as alive if he has more than 4 liberty and if the worm is 
important, we should change the limit to 5 liberties.
What  made me say that gnugo has not what I call a strategy is his first 
moves. Often, he play a san-san. And after he play a shimari. What I 
learn in go is that a san-san just take all the corner in one move and 
so it is
not urgent to make a shimari.
But the reasonment of gnugo seems to be:
1) what to do now? The corner is empty: let's do a san-san I will win a 
lot of point.
2) what to do now? I can do a shimari, let's do a shimari.
But the point is that he doesn't realize that the second choice should 
be done before playing the first choice.

Now I will speak as a 5kyu player, if I say a mistake, the strongers 
players should correct me.
Chosing just to make more score as possible is a bad strategy in go.
When I discovered that having strong groups is more important than, I 
did significant improvments. Someone said if you have not a solid 
position you can't feel free for attacking.

It's my way of seeing strategy, and as often as I play with gnugo,
I would say he has no sense of strategy.
