Hand 1: fold
Hand 2: i fold but i think a call wouldn't be bad.
Hand 3: fold preflop! don't call flop, don't bet river, don't call river.
Hand 4: Call because his play makes no sense at all and it's a very safe board.
Hand 5: your getting like 3:1, easy call.
Where the hell are you playing, what's with this uberaggressive play!?
