Probably i'm better at living, but frankly i have so little confidence in my reading, that i wouldn't say i'm good at living. (But then, i wouldn't say i'm good at anything in go
)
Most of the times i know that my groups are alive, or more precise, know how to make life if it is attacked. Sometimes when i overlook these things (happens too often) and my opponent takes a vital point of my groups i can somehow find a slight weakness in his surrounding stones to make a second eye.
Also i'm a fan of a more peacefull game, both players taking swings at the big points of the game, without a huge dragon-fight, so this might explain this a bit.
When i have to kill it's usually a result of me playing a moyo-game (or more precise, my opponent forcing me into a moyo-game, somehow i can't seem to prevent this), and my opponent invading the moyo "too deep". And then i try to kill the invasion.
But i have a bad experience of these fights going wrong for me, because i misread things at a crucial moment allowing him to escape or live in gote - resulting in me having not enough points to win the game or even continue. After such things i loose confidence and my fighting spirit drops, i often resign after such a failure even if i could continue the game.
Overall this leads to me having a constant fear of misreading things when i have to kill a group to win. Which may be another reason i don't enjoy killing groups as much as other people.
Easiest solution would be doing more problems, but i can't force myself to read when doing tsumego or not regulary enough for it to benefit. I seem to need the pressure of a real game to fully read a given position.
