hand 1: i like it. if you lose, oh well. i think you win here more often.
hand 2: i like the fold. i give credit to button for a str8, or a str8 and flush draw (AJs), given no reads and no prior noise from him.
hand 3: small lead suggests flush or nut draw. RR confirms. call flop/bluff turn...meh. like a fold better here to his small lead.
just my .02
