Hand 1: Nothin particularly wrong with this - weak hand, attempt at a pot steal in a pot that's unlikely to have hit anyone - didn't go, give it up - fine. I'd fold preflop of course but I understand that sometimes you might wanna show down a wacky hand like this for cheap.

Hand 2: Looks good. Could go for more of a steal approach but it was fairly obvious that you had the same hand by the turn/river action.

Hand 3: Makin a move - if they guy can lay down an overpair on the flop - nice -- evidently he can't, which is fantastic information for when you flop a set on him. The turn bet is (as stated) the only woops I see here against this calling station.
