Well, the op called very often (too often against odds) but reraises were very rare so i probably should have known i'm beaten.

after tinkink a while on this hand i considered, that probably a check on the river could have been cheaper to me. if i check he might consider making a small (callable) bet. And if he pushes afer my check i should really know, i'm beaten. But showing weakness on the river could also lead him to a push to get me out of the hand without a showdown.

As you can see, i'm a bit confused about this hand
