Hand 1 is a cooler raisin for the reason u stated as having 2 Q's, but PLEASE 3bet MORE pre-flop!!!!
Hand 2: 3bet the initial guys raise pre-flop. As played, I think you can fold this. AA/KK is a massive proportion of his range here and you need to be right far too often to make the call on the flop.
Hand 3 is disgusting
Hand 4 I call the guy down although I don't mind the flop bet, but I shut down and call down on the turn/river for pot control.
Really unlucky generally raisin, hope it's not affecting you game too much mate.
