H1 flop is meh. Maybe he has enough fd's and weaker hands to bet for value...idk.

Turn is terrible. You get no value here. People dont like folding top pair hands (especially at 2nl) and the fd's got there. You cant bluff him off whatever he might have, and theres no value in betting.

H2: pre std. flop std. turn im trying to get to sd by any means necessary. I call without giving it much thought at all. Your range is waaaaaaay too wide though, and im pretty sure it stems from some kind of results oriented thinking. Most 2nl players in general are loose passive calling stations, so im hard pressed to give him a range i wouldnt open with myself and i find it even more difficult to beleive that he wouldnt limp these hands most of the time if not just folding them outright.
