i show hands when i feel that it is to my advantage.

. I show trash when i get folded to and have crap only if I am generally playing tight and i want people to think i am a nutjob.

. I show good cards when i had a good competitive hand with someone I like as a courtesy IF I feel it will be to my advantage.

. I show good cards when I am rocking on to emphasize how much i rock.

I RARELY tell a hand when it is not shown and when i do i am 95% full of crap.
