Hand 1: I dont like the donk-bet against a loosey at 2nl, i find that it works best against tight passive and tight aggressive opponents. Just some general advice, a hand like TPTK is considered a small pot hand( depends on opponents ofc), so you should use pot-control to try and get a cheap showdown. You dont want to loose your stack with tptk.Just my 2c.
Hand 2: Standard.
