hand 1 is close ; i probably call about 50% of time vs unknowns, probably a little more vs someone like this. If he didn't reriase AK preflop it doesn't mean he played it "weakly", he could have been LOLTRAPPING

hand 2 you usually see a similar hand to yours and his range is slightly ahead of your hand (99-1010 or QQ, sometimes a trappy KK that got scared by that flop). If you're seen villain fold then a 2nd bullet looks very very strong. As played I think you win the showdown very very rarely so I'd usually shove the turn or river (if I'd seen villain fold before).

hand 3 is nice
