Hand 1 - It's weird because why is he suddenly going crazy? Nothing makes sense to beat you so yeah, fine, but I think your river betsize is interesting. Every possible draw missed and you potted it? Think 25c or 30c on the flop gets just as many calls too.

Hand 2 - Nice, really well played calling down instead of trying to rush the money in.

Hand 3 - Someone who is 54/8 limp/calls a 5x iso out of position and c/minraises an A-hi flop? Pretty sure he's going to show up with a bunch of Ax hands here, and you only beat A4 and A5. And then there's 22, 44, etc. You didn't give a read beyond "donk" so I'm just gonna give up the turn. As played never fold river given the price.
