I am curious: is there a way to see, which stats my opponents have collected about me in those hands I played with them ?

No, because all of the stats in the database for you are much more complete than what he/she would have since you always know your hole cards any they will only know this some of the time.

Yes, sure. But it might be interesting, if an opponent has a complete wrong image of me. E.g. he might think i was a fish, because I played some losing sessions with him. He might think I was a maniac, because I was very aggressive in some sessions, but I just have had lots of good cards and a am generally tight passive.

But it isn't really important anyway. As I said, i was just curious.
