Wyps numeric strategies?

For a certain time I keep losing all my games.

What I took for bad luck starts to bugger me...

Would someone offer me some tips, I am mainly interested on when you should try to place many stones and when you should rather turn the important ones.

I had the impression it is good to try to empty the bag so that in the endgame you have more stones than your opponent but apparently that does not work so well.

Also when should you look in the endgame at whether or not you will play last stone in void areas?

Why did you post this post here? I guess if you posted it in word games forum, it 'd be recognized much faster than that :)

My second question is, are you still puzzled?
